What are Domain Authority, Page Authority, and Spam score thumbnail

Greetings! Here you will get detailed information about what are Domain Authority and Page Authority along with Spam Score. All necessary areas are covered in this guide.

When your website grows, you often come to know about domain authority. In the beginning, it is somehow ignored. Although after hearing it so many times bloggers try to understand what is the matter. Probably you have also heard different opinions on it. Some people say it is highly important. Some people say don’t think about it all. Who is right? You can decide and form your opinion after knowing the detail. Here depth information is pulled so that you can out of confusion and help others too.

Firstly we know all the necessary detail of domain authority and page authority. After that spam score will be discussed. Finally, you go deep into some free tools. So let’s dive into the discussion.

What are domain authority, page authority, and spam score

Look at the term. Here authority is used frequently. What does this authority mean?

In simple words, Authority refers relevancy of the website. Another term for it is trustworthiness. When a website has good authority we can consider the website relevant or trustable for that particular information. For example, PETA (People for the Ethical Treatment of Animals) for animal care, Google for search engines, etc.

Therefore, domain authority, page authority, and spam score are indicators of the website’s reliability. By these, you can know how trustable or reasonable to use this website for particular information.

We go deep into all of these. Let’s start with domain authority. Here SEO points of view will be presented.

What is the domain authority in SEO

In SEO, domain authority delivers insights into how relevant the website is for a particular field or industry. These directly relate to how search engine visibility should be for this website.

It is developed by Moz. It provides a score ranging between 0-100 based on the different factors. You will know deeply about all thing. For now, look at an example to start commanding on this topic.

Let’s say, you score 50 out of 100 in Mathematics in your school days. Someone scored 30/100 on the same exam. Here people can identify you good for acquiring more marks.

Similarly, let’s say, the domain authority of your website is 50. Your competitor has 30 for the same field. It is assumed that your website should have better searchability on Google (t&c applied) because you acquire more scores here. Although, it is not compulsory and depends upon lots of other factors.

Similarly what If you have 60 domain authorities in the News niche and your one competitor has 75? Your competitor may get more visibility on the internet. Again, it depends upon lots of other factors too. For firm understanding keep in touch throughout the whole article. Now, let’s discover the detailed meaning of domain authority score.

Domain authority score meaning

You already know it is ranging between 0-100. Here 0 means the lowest domain authority and 1 means perfect domain authority. However, all websites hold 1 DA by default. It increases after the link-building processes.

It is even breakdown further by Moz to get a clear idea. That is –

0-10 –> worst

10-30 –> bad

30-40 –> acceptable

40-50 –> average

50-60 –> good

60-90 –> excellent

90-100 –> ideal

This classification is also accepted by many websites. They use it for their link-building strategy. You may note it for further use.

This score is based on a logarithmic scale. The more you reached a higher score, the more it is hard to increase it. For example, It is incredibly easy to reach from 1 to 10 in comparison from 80 to 90. Above 90 is generally found among big giants like Google, Amazon, etc.

Let’s know how it works.

How does domain authority work

Domain authority is calculated by 40+ factors selected by Moz. One example can be the mesh of inbound links. If you have a better quality of inbound links, you are in a lead.

Although it has controversy in the market. Many claims that There are only two factors that are dominant here. e.g, quantity and quality of a backlink, etc. Look at it.

Domain authority factors

You already know there are 40+ domain authority factors developed by Moz. These are not properly disclosed yet. You also come to know about Authority score, Domain rating, etc developed by Semrush, and Ahrefs.

By not targeting any particular website, here important domain authority factors are discussed. These are –

1) The total number of backlinks:

It indicates the total number of links from another website has a destination on your website. The more you have backlink quantity there are more chances your domain authority will increase.

2) The total number of unique domains:

Let’s say, A-Z is the name of 26 websites. One person gets 100 links from only 2 websites A, and B) Here unique domain number is 2.

Another person has 100 links from 20 websites (A-T). Here unique domain number is 20.

In this example, the second person will get more leads for the Domain authority score.

3) Quality of backlinks:

Quality of backlinks refers to how good the DA score of the website from you get the link. Let’s take the example again.

A, and B are the two websites. A gets 10 links from the different websites which have an average authority score of 20. Whereas, B gets 10 links which have an average score of 50.

Here B website significantly outperformed the A website. These create huge differences despite the same number of backlinks. Therefore, quality backlinks are very much important for domain authority. The more you have quality backlinks, the more your website DA will increase.

4) Relevancy of the backlinks:

It is a crucial domain authority factor. Relevancy indicates how much it is relatable to your website. Again look at the example –

A website has a Food niche. It gets 10 backlinks from Cryptocurrency, C++ programming language (technical), etc niche. Is it relatable? There is a 90% chance of not having the right reasons. Even these types of random links can be known as spammy links. It may hurt the SEO.

B website has a Business niche. It gets 10 backlinks from business, finance, etc niches. Is it relatable? Yes, here relevancy exists. It also depends on whether the link has existed in the relevant post or not. If it is under the relevant place under the relevant post then this is a strong signal for complete relevancy.

Here A website has no comparison to B in terms of relevancy. B is ahead in every aspect. The more your website gets links towards B website example, the more your DA will increase.

5) Link in root domains:

Root domain refers to the highest level in the hierarchy of a domain. At the same time, it is the starting point of all other domains/subdomains. For example, “bloggerguidepro.com” is the root domain for this website. In other words, a domain name without prefixes and suffixes is a root domain.

Here it is noticed how many links are directed to root domains only. It refers to how much people talk about your brand. This type of mention is often found for mentioning the source of content, images, videos, etc. The more you get the link in your root domain, the more your chance of a better DA than those who have less. It also depends upon how intensely this factor is considered by the respective tool.

Link in the root domain can also be looked at another way. If a website passes 3 backlinks to your website, here link in the root domain will be considered as 1. It refers to how many individual websites pass the link to your website.

6) Competitors’ link profile 

Domain authority is a relative term. It depends upon which link profile is comparatively good.

Let’s say, You and Amazon are tough competitors. You built your domain authority at a certain level. After that Amazon gets a massive link from others. Your DA may fall without doing anything. The reverse is also true. If you acquire massive backlinks, Amazon may have relatively less DA than the previous one. However, a generally massive drop is not found in these cases because of a large market area.

The above discussion is for putting the point that competitors’ link profiles affect the DA score.

7) Social media presence:

This factor is related to bookmarking social sites. Let’s take the example.

A website has focused only on organic traffic and not the account in social media. There is significantly less content is bookmarked on social sites. Therefore it has a less social media presence.

B website has an account on different social media. It has been massively bookmarked on social media like Pinterest, Facebook, etc. Therefore it has a strong social media presence.

In this case, B’s website is far better than A website In terms of social media presence. Therefore, It may ahead in DA if the respective tool considers this domain authority factor.

Here you may get feared. Let be mentioned that Google does not say that it is the factor that is considered by them. Even Google professionals denied it because massive manipulation can be done here. Moreover, here domain authority factors are discussed. It will be discussed letter if is there any relation between domain authority and Google considering factors.

8) Search engine traffic and ranking

Yes, it is a considerable factor. Even it is easy and a dedicated factor. DA and ranking are dependable on each other. Increasing DA refers to better visibility in search engines. Another side, better visibility automatically refers to a good DA. Therefore, rank-worthy content indirectly plays an important role to increase your DA.

9) The mesh of internal linking:

Internal linking is the only do-follow link that is completely in your hand. It can increase your page authority. This also helps to increase the domain authority. Moreover, internal linking sends a strong signal to google that your website has rich information.

In some cases like news websites, this opportunity is less. However, for any static articles, internal linking opportunities should not be missed for higher visibility in search engines as well as for DA scores.

10) Number of do-follow and no follow backlinks 

No-follow backlink increases domain authority. However, do-follow links have a major role in it. Therefore how many backlinks are do-follow or no-follow helps to determine the DA.

11) Updating algorithm by DA checker tools:

DA checker tools update the metrics to make them more relevant with time. It also causes because of Google updates. DA checker tools try to maintain the similarity as much as possible. You can understand it by one example.

Moz updates its matrix (DA 2.0 matrix) in 2019. It causes the falling of DA scores like 5-7 of the websites. The given reason is to make the DA score more compatible with Google rankings.

Apart from that 12) content quality, 13) SEO performance, etc is also considered by a few tools.

A detailed discussion of the domain authority factor is put in. Now, look at How to find out the domain authority number or scores of a website.

So you knew how to find a domain authority number of a website. We will know about many tools later. Now let’s look at what is a good domain authority number.

What is a good domain authority number?

Here is one thing that needs to understand. It should never use as a number for good domain authority. Instead, it must be used comparatively. If your DA score is better or similar to your competitor’s website, you are in a better position. It can be understood through two cases.

Case -1 (Small Local businesses):

Let’s say, your online business belongs to a particular region You checked your competitor’s DA. These are 15, 32, 23, etc. You found the average DA is 25 and the highest is 34. Now your DA is 31. It can be considered a good domain authority. In another case, you have 10 DA which is below average (below 25). In this case, you can consider improving it.

Case 2 (Big global giants):

Now you have a global presence. Your competitor is Facebook, Twitter, etc. You found Facebook has 96 DA and Twitter has 94 DA. Let’s say, the average DA is 90. Now your DA is 80. It is still less than average and there is a long way to go. Continuous improvement may achieve the same or better position.

Therefore, a good domain authority number is solely dependent upon your competitors.

How to increase the domain authority of a website

Now the question comes to how to increase the domain authority of your website. Will it improve automatically or have a proper strategy to increase it? The answer is both.

Two main types of SEO are On-page and Off-page SEO. Quality content, keyword optimization, etc comes under On-page SEO. Link building, brand awareness, etc. comes under Off-page SEO. If your On-page SEO is excellent, Domain authority will improve automatically over time. Another side you can focus on link building, and brand awareness to make this process fast. Here are some crucial strategies for improving the domain authority of your website.

1) Use Link building strategy

Understanding, implementing, and managing the links comes from another website is known as a “link-building strategy”. This helps to improve the Domain Authority.

When you get a fresh domain, its DA is 1 by default. As before discussed a good DA can be identified by looking at competitors. It is an exception to beat your competitors without DA.

Which one thing is essential to remind for implementing link building strategy? It goes with the natural links. These days people use invalid practices to build links like a bulk order of buying backlinks. These harm the website in long run. It is not about getting the link anyway. Ultimately, through hard work or by an SEO expert these processes should be gone through naturally like pitching the website, building relationships, etc.

2) Produce linkable content

Content is king! This is equally true for increasing the domain authority of a website.

Did you notice which links you are mentioning in your article? Ask yourself. You can also get links by introducing that type of content. Here are some common features to include linkable content –

i) Share accurate information. People like authenticity and fear including any controversial or biased content.

ii) Produce the best content on a particular topic. People love to share information that is best on the internet. That is the reason why big pages get free promotions on Facebook, Pinterest, etc.

iii) Write comprehensive content. If you need to give all-in-one information to your clients which pages you may refer to? The article clears the doubt of your audience or finds worth value in it. Right? Generally, a comprehensive article includes many things in detail. Therefore it is a better chance to get natural links in long-form of posts.

iv) Make content with the primary data. These days primary content is at the top level. Case studies, surveys for statistics, etc primary source data get a huge backlink. You may notice frequent links for mentioning statistics in different posts.

v) Produce trending and shareable content. Trending topics is highly shared within less time. These are also mentioned when secondary content is written. Moreover, research trending topics and which is most shared on social media within your niche. This helps a broad reach of the content which helps to get natural backlinks in posts.

Here are a lot of discoveries waiting in the way.

3) Do competitor analysis

It is one of the most vital things for increasing the domain authority of a website. Why? It gives you a direct hack of content that gets backlinks. After understanding this it is far easier to produce content like that. For easy understanding consider the below example –

For competitor analysis, you can go to Ahrefs free backlink checker page.

Ahrefs free backlink checker page

Enter your competitor’s website URL and look at the result.

competitors backlink analysis

Here SERP snippets and guest posting lists are discovered. It is understood that posts that are not very common but important get links from another website. You can create posts accordingly. If your content is highly useful then you can pitch your content to the respective website. The success rate is not very high but you can get results depending on the content quality. It is a major strategy for many high-authority websites. There is one more like that.

4) Do broken link analysis to get a backlink

It is similar to the previous one but with a very high success rate. A broken link refers to when a page does not exist for this link. It creates a 404 error. No one likes that. You can take advantage of it in 5 steps.

i) Make a list of websites that provide backlinks to your competitor’s page.

5) Do regular guest posting

Guest posting is a popular method that starts from the beginning. The guest posting indicates when you write an article for another website. They will get quality content for free and you may get a backlink as a reward in the relevant posts.

Consider this popular blogging statistic. “1-5 guest posts in a month are written by more than half (60%) of the respondents” (Referral rock)

You can join this party. It is worth considering posting regularly on guest posting sites related to your niche. Over time you will get large traffic along with brand awareness and backlinks.

6) Build do follow and no follow backlink

Do-follow and no-follow links are important for increasing the domain authority of your website. Simply any good links pointed to your website are a signal of trustworthiness.

Many ones have confusion. Is a no-follow link harm the website? Well, this question is also asked on Google search central. Matt cuts share the answer on September 9, 2013, in a youtube video. The simple answer is no until it is causing a huge amount of intentional spamming.

Therefore take the advantage of everything. Broken links, guest posting, etc are for a do-follow strategy, and blog commenting, opening an account in web 2.0 sites, etc are for a no-follow strategy. You can know in detail 31+ tactics to get backlinks for free articles.

7) Diversified your content through Email, Podcast, social media, etc.

The main motto of this point is to diversify your rich. It can be a podcast, RSS, google uploading image sites, email, newsletter, different social media sites, etc. This reach helps you to create brand awareness. People are more comfortable linking a brand. In this journey, you will also get vast experience and a strong network to grow easily with a smart strategy.

8) Remove Spammy backlinks

Removing the bad stuff is also a firm strategy. You made your authority slowly and with due effort. You do not like to get this down without any reason. Therefore, you may consider removing spammy links.

For that, you can use Google stuff. Go to this Disavow links page and request for removing any spammy links. Here one thing is to remind you, It can be the last step and you must be sure about the reason. Otherwise, taking random use may affect your site.

9) Work on On-page SEO

It is an essential element. The more you have improved in on-page SEO, the more you are ahead in this game. Why? It causes the expanding reach of the internet. That automatically generates a natural backlink for whoever finds it as helpful. You can better idea from these references –

iv) Perfect keyword optimization through 14 places.

Now last but not least.

10) Work on Technical SEO

Technical SEO is directly related to bounce rates. Bounce rates significantly impact the natural backlinks. Website speed can be taken as an example. If your site takes much time to open, users will leave your site before interacting. Another side, If your pages load fast, users have a great experience. It leads to an increase in Ranking as well as getting many natural backlinks.

Similarly, the Structure of the data, SEO performance of the sites, Clean and attractive interface, etc technical SEO will be maintained properly for the best result.

That is the end of how to increase the domain authority on a website. The domain authority is discussed in detail. Now, dive into the page authority. First, look at what is page authority.

What is page authority?

Page authority is developed by Moz to predict the strength of the individual page for SERP ranking.

It is based on dozens of factors and results by an algorithm based on a machine learning model.

Page authority scores range between 0-100. The more score goes towards 100, the more it has a chance in the SERP ranking. It is based on a logarithmic scale. That means achieving 10-20 page authority is exceptionally easy compared to 90-100.

Now let’s know how to check the page authority.

How to check the page authority

Many tools will display your page authority. These will be discovered later. Here Moz tools are mentioned which is similar to checking the domain authority. These are –

i) Free domain SEO analysis tool

ii) Meet link explorer

iii) Keyword explorer by Moz

iv) Mozbar chrome extension

v) Mozscape API

Now, let’s discuss what is a good page authority number.

What is a good page authority number?

There is a need for clarity about one thing first. There is no fixed range to identify good page authority. Instead, it is used s a comparative tool. It depends upon what is the page authority score of your competitor’s page on which you want to rank. Look at the below two different examples for clarity.

1) Rank on “Blogger job description” (low difficulty):

The Blogger job description has easy difficulty and less search volume (100 in the United States). The page authority of the first 5 SERP results is consecutively 46, 32, 24, 24, and 28. Here 30 can be considered a good page authority. Although it is for rough understanding only. Ranking depends upon lots of other important factors.

2) Rank on “SEO” (short tail keywords, high difficulty):

SEO has very high difficulty and high search volume (111k only in the united states). The top 5 results and their page authority are consecutively 65, 39, 71, 59, and 45. Here 30 may not be a good page authority. It needs to be improved to get a better result. Here 60 page authority can be considered as good.

You knew how to understand it by looking at the competitor’s page. Now it’s time to know how to improve the page authority.

How to improve the page authority

It covers most of the important aspects of blogging. However, some major considerations are –

i) Content is king and plays a major role here. So write highly useful content that people love to link.

ii) Create an inbound link (link to your pages from another website) for the specific pages which you want for a better PA.

iii) Link internally from another page that has a high DA. Make sure these are relevant to the link. By the proper interlinking, you can easily get a few Page Authority.

iv) Share your content throughout social media so it has the chance to get links/mentions by users.

v) Remove spammy links for this particular page. It can be done by using Disavow links by Google.

I hope, it is well known about Domain Authority and Page Authority. Let’s make it more clear by knowing the difference between them.

Domain Authority and Page Authority difference

For easy understanding, it is explained through four major points. Enjoy this difference.

1) Scope:

Domain Authority helps to predict the ranking visibility of the entire website. Page Authority helps to predict the ranking visibility of individual pages.

2) Calculation

Domain Authority is calculated over 40+ factors. Page Authority is calculated over dozens of factors but not includes specific on-page elements like content optimization or keyword use.

3) Score:

A 0-100 DA score represents the strength of the entire website. A 0-100 PA score represents the strength of a single page on a website.

4) Importance:

Domain Authority is the first thing to consider by everyone. Many bloggers know about Page Authority later. For a greater DA website, competing with less or average PA will be relatively easy.

You also folded it. Now, look at a vital fact.

Is DA important for ranking in Google?

It is a controversial topic in the SEO area. However, that can be answered very easy way.

DA and PA are invented by Moz and not by Google. Moz clearly stated that DA is not the factor for Google ranking and it has no effect on SERPs.

Anyway, In a video of Google search central, it clarifies that Google does not consider it. At the same time, it is mentioned that Google uses its separate metric for it.

Let’s end this debate. First thing why Moz will take responsibility that it relatively matches with Google. If it does not match then what is the use of it? Moz considers DA, and PA to have no relation to avoiding taking any responsibility. Google does not need to follow another tool like Moz. Google has enough strong algorithms to detect it.

The knowledge of DA and PA is based on the quality of the website and pages. If DA and PA are forgotten then also these criteria are valued a lot.

If you manually check over the internet, there is a strong correlation between domain authority and ranking. You can check high-difficulty keywords SERPs. 8 out of 10 belong to the high domain authority. In low-difficulty keywords, there is a mixture of high DA and relatively lower DA.

The problem arises when people started to collect the links through invalid practices. Otherwise more natural backlinks directly indicate the relevancy of the content. Therefore, it naturally tends to rank. Even Facebook, Instagram, etc also try to detect valuable content by engagement.

Google considers a lot of factors for ranking content. Therefore it is never found that DA 73 must be above DA 71 in the result. Rather than that, Take it as if all the qualities are equal then better likable sites can get priority. It is better to take Domain Authority and Page Authority in a range like “40-60” or “60-90” etc. An above example of SEO consecutively 65, 39, 71, 59, and 45 are found. Here the range can be 35 and above. It matters. If DA is 1 or 10 then very rare chance to beat them.

Now conclude. DA has somehow proper relation (because of its valuable factor) with ranking but in a range rather than an individual number. SERP depends upon the content quality first and not on DA. After that, DA and PA matter depending upon your competitors at the domain level and Page level. You can take pre-steps and post-steps accordingly. Clear!

Let’s take one more step here.

When to focus on DA and PA

Confusion on this matter has a chance of mistracking. It is not funny that some people start to build 50+ DA with only 5-10 low-quality content. For those who do not interact directly with an audience, it is hard to believe. That is the wrong practice. Maybe this site was unlucky enough to get free traffic at the beginning but soon it looks like 1k to 10 organic impressions. It hurts and makes unstable them.

Then when to focus on DA. It can be understood through three steps.

i) Is the content rank-worthy now? Is it properly optimized for the keyword, SEO, and from every aspect? Ask yourself. If that is ok then go to the next step.

ii) Is it followed best practices for technical SEO? It may be Site speed, Accessibility, best practices, etc. If yes then go for the third step.

iii) What is my plan to manage DA and PA to beat my competitors? How it can be achieved through valid practices? Get the answer from yourself and build Domain Authority and Page Authority accordingly.

After these practices, your content will be ready to look better result.

Apart from Domain Authority and Page Authority, one important factor provides hints for your website health. It is Spam Score. Let’s know what is the spam score.

What is the spam score?

The spam score is a metric used by Moz to indicate the matching percentage of similar practices websites which is previously penalized or banned by Google.

It belongs to range from 0% to 100%. The more score represents there is more chance it can be considered a spammy website.

Moz uses 17 signals to estimate this percentage. Not having an email address, Default to HTTPS or not, Number of external Outlinks, presence of poison words, etc are a few of them. The more it matches the indicators, the more percentage is shown.

A greater spam score is not necessarily the website that must be spammy. Instead, It is used for further investigation to make sure everything is fine.

Spam score checker
