In Google's PageRank, its algorithm evaluated the amount of traffic and the quality of the links to a site, with these data it calculated the level of relevance
that the content of your page has for the user, and it assumed that the more traffic, quality, and number of links, greater interest users had in the contents of a page.
The PageRank rating was assigned from 1 to 10, the higher the rating, the higher the page was considered and the better position it had in the search results.
The MOZ tool uses these and many more variables to qualify the Domain Authority and assigns a score from 1 to 100 that works in principle equal to PageRank: the higher the score, the greater the ability of our site to qualify in the first search results.
According to MOZ, the Domain Authority rating is based on machine learning calculations that compare the metrics obtained from the evaluation of a site, with the metrics obtained from the millions of sites that exist on the internet.

Some key points of MOZ

• It is a logarithmic scale from 1 to 100 points, which means that it is much easier to go from a low score of 10 to one of 20 than to increase from 70 points to 80 or more.
• The difficulty is that the higher the score, the SEO factor in the sites with which you compete is much higher, and therefore, the effort must be greater.
• Due to these calculations, a site's score may change as the algorithm uses different variables in analyzing this data. For example, taking as reference our explanation of Google PageRank
, which MOZ also uses.

If a website like ours is linked to millions of pages, the Domain Authority of other sites that classify in the SERP with our same keywords and that have not had this same level of links would fall with ours.
There is something clear that we must take into account: the qualification or the result that the Domain Authority gives should be taken as a relative metric to compare our SEO efforts against the millions of existing sites on the net.

Tips for ranking your site

1. Use keywords in the writing of the content of your main pages naturally and fluidly, make sure that it is a content of at least 400 words.
2. Make links between the content of your site, make sure that your content is well optimized for search engines.
3. Start link building campaign with other websites with the highest Domain Authority and allow tracking of these links to your site.
4. Remember that Google penalizes the purchase of links to generate traffic, we must ensure that the pages that are linked to our website are useful for the user and their score is very good.
5. Make sure you do not have images, files, or contents in error 404. The bad user experience is a reason for penalizing the SEO of our site.
6. Share the contents on social networks, if the social network is specialized, include your site as a source of consultation on fragments of the article or page to which you want to redirect the user.
7. The list of variables to take into account SEO is quite long and depends on each audit tool.

Achieve a good grade

Regardless of the tool, we used to evaluate our efforts when trying to position the site in the search engines, we must consider optimizing the greatest number of these variables to achieve a good rating.
A good SEO strategy that is focused on raising the content level of the pages of a site is essential in the task of increasing Domain Authority.
