Domain metrics have a huge impact on how well your website ranks in Google search results. Not only that, if you perform this task well, you could find yourself in a stable position at the top of page one.

Domain metrics are made up for three key areas: Domain Authority, Page Authority, and SEO Moz.

Domain Authority – DA

Domain authority is not a new phrase in the world of SEO, but there are many SEO specialists who are unaware of it and its significance.

Domain authority is a metric created by Moz (an SaaS company), for the purpose of rating a website on a scale of one to 100 (100 being the best and one being the worst). The higher the domain authority of a website, the higher it ranks in search engines.

Although domain authority is a good way to measure the success of your SEO, it’s also the best way to compare your ranking with your competitors. The best way to check this is with this domain authority Moz checker by SEO review tools.

All you have to do is type in your website’s URL…

Then go scroll down to see your domain authority score…

All you have to do then is make a note of your score, and perform the same search for your top competitors.

Underneath your Moz domain authority is the number of backlinks to your site, a main contributing factor to your DA. There are over 40 different ranking signals that boost your domain authority, so we’ll leave that for another piece.

Page Authority – PA

Page authority is another metric created by Moz that predicts how well a specific page will rank on search engine result pages (SERPs). Like domain authority, page authority is ranked from one to 100, with higher scores corresponding to a greater ability to rank.

Page authority is based on data from Moz’s web index and, like domain authority, it uses machine learning to identify the algorithm that best correlates with rankings across the thousands of SERPs.

This metric is scored on a 100-point, logarithmic scale. Therefore, it’s significantly easier to grow your score from 20 to 30 than from 70 to 80. These algorithms are constantly updated so you may see your score fluctuate from time to time.

If you want to check your page authority, you can use the page authority checker by SEO Review Tools again.

This time, type in the URL for the specific page you want to check and hit “perform check”…

Again, you can use this tool to compare your score to your competitors.

SEO Moz/Trust Flow – TF

Trust Flow is a metric trademarked by Majestic that analyses how trustworthy a site is by measuring its quality, which is the essential data of this metric.

If a link pointing to your website is authoritative and qualitative, then your trust flow will increase. These are the “backlinks” we mentioned earlier.

Google rewards qualitative backlinks dependant on how authoritative the site linking to you is. The more trustworthy a site linking to you is, the better chance you have of ranking on the first page of Google.
