25 Off-Page SEO KPIs to Measure Your Authority


Why Key Performance Indicators Matter in Off-Page SEO?

Key Performance Indicators (KPIs) are measurable values that demonstrates the effectiveness of an activity (and the person or team behind) in achieving their objectives.


KPIs are crucial for monitoring progress, identifying areas for improvement, and making data-driven decisions to optimize performance and drive success. KPIs are used across all industries.


SEO isn't an exception. Without measuring SEO KPIs, you have no idea if your SEO activities are effective.


To solve that issue, I created several months ago a free document summarizing 22 SEO KPIs in order to help you monitor the performance of your SEO activities. Hundreds of you downloaded it.


And now I've added 23 new KPIs related to off-page SEO, so there are 27 off-page SEO KPIs in total in the document. You'll be able to fine tune your measures and find the more specific ones based on your off-page SEO needs.


The updated document is still free, and now available as the 45 SEO KPIs (yes, I'm good at Maths ;).


Leverage it to implement my 10-step process to audit your website authority.

1. Website Authority

These metrics allow you to measure the website or page authority from both your website and that of competitors. They are calculated by SEO tools with proprietary formulas.


  • Domain Authority (DA) by Semrush or Moz, acknowledging these are too distinct measures.
  • Domain Rating (DR) by Ahrefs.
  • Domain Ranking (DR) by Open Link Profiler.
  • Page Authority (PA) by Moz.

2. Number of Backlinks and Referring Domains

The main components of your off-page SEO activities are backlinks, and you should work towards increasing their quantity:


  • Number of backlinks.
  • Number of referring domains.

3. Link Juice

Measure these attributes to understand the quality of your backlinks, especially to know if they are building your authority or not.


  • Number of DoFollow backlinks.
  • Number of NoFollow backlinks.
  • Number of sponsored backlinks.
  • Number of User-Generated Content (UGC) backlinks.

4. Link Velocity

These measures will help you assess the impact of your link building efforts, control your existing links, and eventually update broken links.


  • Number of new backlinks.
  • Number of lost backlinks.
  • Number of broken backlinks.
  • Number of new referring domains.
  • Number of lost referring domains.
  • Number of broken referring domains.
  • Net Link Growth
  • Link Velocity.
  • Net Referring Domains Growth

5. Link Toxicity

These non-conventional KPIs will offer another insight about the quality of your backlinks; offering you the opportunity to find out and remove the toxic ones.


  • Toxicity Score, by Semrush.
  • Spam Score, by Moz
  • Number of toxic backlinks.
  • Number of non-toxic backlinks.

6. Anchor Text

While anchor texts are difficult to change on websites you don't control, there are still options you can leverage. If you are working towards improving your anchor texts, then identify the good and bad practices with these metrics:


  • Backlinks with anchor text.
  • Backlinks without anchor text.
  • Backlinks with exact match anchor text.
  • Backlinks without exact match anchor text.

Formulas and Tools

In my 45 SEO KPIs document, you will find the formulas or tools to use the obtain the values, as well as a description of each individual KPI.


If you'd like to see its implementation on a real case, read this article: Case Study: Off-Page SEO Audit of JuGo Graphic Design. Steps, raw data, spreadsheets and results are showed.


And if you want to get your off-page SEO audit to measure your own authority and analyze your backlink profile, then you can either do it yourself with my course or have it done for you with my SEO agency service.


In both cases, you win ;).
