The Authority of my Website, what it serves and how to Measure it

More or less when we talk about the authority of a website we all have a vague idea of what it means: the authority of a website is its prestige, the relative importance it has over the rest and, ultimately, value and quality Which has our website. Now … What good is a high web authority?

First, if our site enjoys high authority, Google will be much more forgiving and lenient about techniques that may be morally questionable. This not only protects us from internal faults (who have not missed a link where they should not be link building) but also protect us from external attacks. For example, if a competitor chooses to bombard our website with foul links, our page will not be so affected if it has a high authority (please, if I have perfect authority, how am I going to be so despicable to put a link on a farm Of links). At the end of the post I will tell a rather funny anecdote about this topic.

The Authority of my Website, what it serves and how to Measure it

In addition, the high authority also affects the quality of our links. If we have a high authority, our links will have much more value than other sites with much lower prestige. This in the long run can lead to the temptation to sell these high value bonds.

Anyway, how can we measure this authority?

Basically there are three indicators to measure authority:

The first indicator to measure the authority of a website is the Page Authority of a site. The Page Authority is an indicator created by SeoMoz that predicts the probability of each page of a website ranking well in Google searches regardless of Google (Note, do not confuse page with site, page , A website is a location that includes a multitude of pages organized hierarchically). The Page Authority is measured with a value between 1 and 100. It is important to point out that it is quite simple to increase from 1 to 10, something complicated to increase from 40 to 60 and practically impossible to increase from 90 to 100. To measure it, we will use the Open tool Site Explorer (owned by SeoMoz).

By emulating Page Authority, the Domain Authority is another indicator created by SeoMoz that measures the likelihood that a domain (ie, the particular site) will rank well in search engines. We can also measure it with the free version of Open Site Explorer. Anyway, if you want to measure Page Authority or the Domain Authority with relative frequency I recommend you install this plugin (available for Chrome and Firefox) that will automatically indicate these values, both in the search results and on the pages themselves.or you can check also via some online tool if you have more than 1 domain you can check this Bulk Domain Authority Checker.which is 100% free and easy to use.

The last indicator of the authority of a website is PageRank. PageRank is a numerical value (between 0 and 10) that represents the popularity that a site has on the Internet. This indicator is patented by Google and owes its name to its creator, Larry Page. Its operation is extremely simple: When page A links to page B, page B receives value (what we know as juice) from the first page. The more links you get from different sites, the more your popularity increases. Increasing the PageRank of a website is the main goal of link building. There are many pages to measure. I recommend that you download these SEO tools, where you can instantly see in your marker bar, among other things, the PageRank of each website.


As a curiosity, never forget that the PageRank that these tools mark you is different from the one that Google has in its algorithm. The PageRank we see is updated every 3 or 4 months but the Google algorithm is updated daily so who knows, even my blog has already reached a PageRank 3.

SeoMoz case.

I owed you an anecdote and an example: here you have it. The SeoMoz page has a Page Rank of 6, a Domain Authority of 94 and a Page Authority (the home) of 93. The authority of this domain is practically unbeatable.

When Google wanted to prove that the fruitful links of Negative SEO, created by our competition to smash our SEO position, did not affect the positioning did the test with SeoMoz. The first conclusion was that the Negative SEO did not affect the search results since the positions for the keywords for which SeoMoz was positioned were hardly affected. However, this was something to be expected, since a site with such authority … It is untouchable! But what if the example had done with a page with a PageRank 2, a Domain Authority of 30 and a Page Authority of 28? They eat it!
