When it comes to website Authority we have a few different vendors who have each their own method to measure the authority of a website. The goal of these methods are the same. Google’s algorithm is called Page Rank, Moz’s is called Domain Authority and Ahrefs’ is called Domain Rating.

What is Domain Authority and what is Page Rank

In this article we will discuss what Authority is and we will look at some of the elements that gives websites higher Authority and thus higher ranking in Google.

What does Page Rank mean?

PageRank is a rating system developed by Google that assigns a numerical weighting to each element of a hyperlinked set of documents, such as the World Wide Web, with the purpose of “measuring” its relative importance within the set. The algorithm may be applied to any collection of entities with reciprocal quotations and references. The numerical weight that it assigns to any given element E is referred to as the PageRank of E and denoted by PR(E).

PageRank was named after Larry Page, one of the founders of Google. PageRank is a way of measuring the importance of website pages. According to Google:

“PageRank works by counting the number and quality of links to a page to determine a rough estimate of how important the website is. The underlying assumption is that more important websites are likely to receive more links from other websites.”

In other words, if many other websites link to a particular page, then that page is probably important and should rank well in search results.
The Page Rank Scale is logarithmic


What is Domain Authority?

Domain Authority (DA) is a search engine ranking score developed by Moz that predicts how well a website will rank on search engine result pages (SERPs). A Domain Authority score ranges from one to 100, with higher scores corresponding to a greater ability to rank.

Domain Authority is calculated by evaluating multiple factors, including linking root domains and the number of total links, into a single DA score. This score can then be used when comparing websites or tracking the “ranking strength” of a website over time.

It’s important to note that Domain Authority is not a metric used by search engines like Google in determining search rankings, and it should not be used as the sole criterion for evaluating the importance of a website or page. However, it can be a useful tool for comparing the relative importance of different websites or pages.


What is Domain Rating?

Domain Rating (DR) is a metric that was developed by Ahrefs, a company that provides tools for analyzing and tracking websites. It is used to measure the strength and popularity of a website or domain, with a higher score indicating a stronger website.
The DR of a website is calculated based on a variety of factors, including the number and quality of external links pointing to the site, the age of the domain, and the strength of the websites linking to it. DR is used as a way to gauge the authority and credibility of a website, and is often used by SEO professionals to help assess the potential value of a link from a particular domain.



What is Backlinks and what do they mean for Ranking?

Backlinks are incoming links to a webpage. When a webpage links to any other webpage, it’s called a backlink. Backlinks are also called inbound links, incoming links, inlinks, and inward links. Backlinks are important for SEO because some search engines, especially Google, will give more credit to websites that have a good number of quality backlinks, and consider those websites more relevant than others in their results pages for a search query.

Backlinks are a way to get higher rankings in search engines. If you have backlinks from high-quality and authoritative websites, search engines consider your website to be of higher quality and relevance, which can lead to higher rankings in search results. However, it’s important to note that the quality of the backlinks, not just the quantity, is important for ranking. It’s also important to avoid using any tactics to try to get backlinks that are against search engine guidelines, as this can lead to penalties and reduced rankings.


Domain Authority and Domain Rank is a logarithmic scale.

A logarithmic scale is a scale used when there is a large range of quantities. It is based on orders of magnitude, rather than a standard linear scale, so the value of each tick mark on the scale is a fixed multiple of the previous tick mark.

For example, a logarithmic scale with a base of 10 might have tick marks at 1, 10, 100, 1000, etc. This is because each tick mark is 10 times greater than the previous one (1 x 10 = 10, 10 x 10 = 100, 100 x 10 = 1000).

Logarithmic scales are often used when the range of values being plotted is very large, because the logarithmic scale can compress the large range of values into a more manageable range on the plot. This can make it easier to compare values that are vastly different in magnitude.

It’s important to note that the logarithmic scale is not the same as a linear scale, where the value of each tick mark is a fixed increment greater than the previous tick mark (for example, a linear scale with tick marks at 1, 2, 3, 4, etc.). The logarithmic scale is based on orders of magnitude, while the linear scale is based on a fixed increment.

This means the first backlinks are easy to get, but the more you get the harder it becomes to get more.

This is just an example with a logarithmic base of 5. DON’T take the numbers as a guide. It is ONLY an example and only a handful of people knows the real numbers in the algorithm. ALSO remember the quality of the backlinks matters and it matters if it is a dofollow link or a nofollow link. And there re probably hundreds of other factors in play here.

to get your blog from DA 10 to DA 20 you need 20 relevant backlinks
to get your blog from DA 20 to DA 30 you need 100 relevant backlinks
to get your blog from DA 30 to DA 40 you need 500 relevant backlinks
to get your blog from DA 40 to DA 50 you need 2.500 relevant backlinks
to get your blog from DA 50 to DA 60 you need 12.500 relevant backlinks
to get your blog from DA 60 to DA 70 you need 2.500 relevant backlinks
to get your blog from DA 70 to DA 80 you need 62.500 relevant backlinks
to get your blog from DA 80 to DA 90 you need 312.500 relevant backlinks
to get your blog from DA 80 to DA 99 you need 1.562.500 relevant backlinks
to get your blog from DA 99 to DA you need an infinite number of relevant backlinks

The point here is to show you that it gets much harder to get backlinks the higher Domain Rank you have. The numbers are NOT exact. Only an illustration.


Why do I need Domain Authority?

Domain Authority decides how high you rank on Google and backlinks is the most important factor to consider when trying to rank on Google. Without Domain Authority you are getting nowhere.


How to increase Domain Authority

There is only one good way. You need backlinks. High Quality Relevant Backlinks.


You Can’t Trust Google and Bing!

 Unfortunately that is a fact!

Their indexing is run by Artificial Intelligence and it makes mistakes. Just like humans. And like most humans AI doesn’t learn from it’s mistakes. They are simply not programmed to do so!

You Need To Check Google WebMaster Tools and Bing WebMaster Tools ALL THE TIME.

I have seen a lot of sites suddenly being removed from their indexes. And that hurts! All your organic visitors disappear.

A HUGE problem when Google and Bing removes sites from the index is they DO NOT TELL YOU WHY!!! They ONLY refer to their guide lines and when you check them (I can recite them in my sleep), you find that there is nothing in the guide lines you have violated. Nothing! Not even close.

As I told you – They make mistakes!

And another thing!

Google is very well known to be political biased. We saw that under the Trump campaign where democratic bastions got boosted and Libereal web sites got down ranked in Google. And Tulsi Gabbard got her Google Ads account suspended for no reason – other than they wanted Hillary Clinton as president!

Unfortunately it backfired on them! Luckily – I will add fast!

If Google decides they have enough great information on a topic and you try to add something to the mix that does not contribute with anything new, they might reject to index your site!

That is what they claim and unfortunately it looks to be true.

This is a pain in the ass for new websites because how the Screaming Duck are new websites supposed to compete with established web pages that have millions and millions of pages?

Google are arbiters of taste and Bing has become too. They decide what is in the index or not. Google believes they have an democratic attitude, but this exact attitude is actualy ultra liberal! 

Well, politics aside!

The only thing you can do is to make sure your website is top tuned and your content in relevant! And RELEVANCE is the new keyword here. Relevance is mainly determined by searches. Secondary on Google poltics!

And make sure you submit Sitemaps and if you find non indexed pages in Google Search Console, submit them again! Same in Bing.

I found it is a great thing to check your rankings in all the major search engines. Ig you are no. 1 for your keywords in Yandex and Baidu, but non existing in Google or Bing there is something totally wrong. Probably with the search engines, but we have to get them back if we want organic traffic.


How to rank higher in Google

To rank higher in Google you need a few things.

  • You need to research keywords and use them in your article. Rank Math and Yoast will check if you use the keywords enough times.
  • You need articles 2,500 – 4,000 words
  • You need diverse backlinks. Dofollow and nofollow. Backlinks from low ranking pages as well as high ranking pages. But NOT from dirt sites! They should be disavowed using Google Disavow Tool.
  • You need to check in WebMaster Tools that your pages are indexed AND ranking. That is two different things.
