We Studied Over 1 Million Domains to Find the Most Common Technical SEO Issues

There’s a lot that can go wrong on a website, and every site is going to have some issues to fix.

We looked at 1,002,165 domains to find the most common technical SEO issues. Keep reading to see what we found.

What should you fix?

What you prioritize to fix will be determined by the scale of the issues and which ones you think will have the most impact for your site. 

We have a default prioritization for issues in Site Audit, but you can edit the priority by going to “Issue settings” at the top right of the Site Audit dashboard. I’ll warn you now that changing the issue prioritization will impact your Health Score!

In fact, you can fully customize the issues. You can edit existing issues, create new issues, change the priority of issues, or turn off ones that don’t matter to you.

Prioritizing fixes or even determining if you should fix some issues is one of the hardest parts of technical SEO. It gets even more complicated when you have to weigh fixing technical issues along with things like creating content or links. 

Sometimes, the best course of action is to do nothing because the costs outweigh the benefits.

I don’t want to make assumptions about your sites in this study, but I have listed some of the projects I would prioritize in our beginner’s guide to technical SEO. We also have guides on doing a technical audit and fixing technical SEO issues to give you more ideas.

The way I usually prioritize issues is by the impact I believe they will have and the effort that I (or my dev team) believe it will take to fix them. This makes for a nice visual for presentations and helps you see which fixes will have the most impact with the least effort.

Final thoughts

A huge thanks and shoutout to my colleague, Oleksiy Golvoko, for helping me gather this data! It was interesting to see the issues at a scale that has never been done before.

In case you missed the other two links to it, here is a sheet with the rest of the issues.

Dan was a delight to work with. I needed a few headshots taken for my LinkedIn profile and Dan provided the easiest and most comfortable experience using state-of-the art equipment in a very professional setting. Also, the turn-around time on results was quick and I felt completely engaged and satisfied during the entire process. I highly recommend his services.Donny RitcharoenDecember 19, 2023

It’s so rare in these times to find one man with so much wow factor and more rare to find men with similar interest and passion in their life journey as myself . Dan Elliott has been introduced to many in what is now considered as the Terror Dome , a place where many dreams are not deferred they are detoured to routes that lead to dead ends , he comes in full of optimism so infectious that he, maybe with out knowing is energizing those who have ventured where others would fear going with just the right jolt to forge on in the way of helping fallen humanity … His various fields of expertise has helped many in my region and I can only imagine the number he has effected beyond those I know … from day one I knew “ this was a man of kindred spirit “ Dan Elliott is a Gem and adds glimmer to things he touches … I’m a Witness ….and eternally grateful….L.Rashaan RichMay 21, 2022

We'd used some other agencies before, but man, they simply knocked us all over. After being in business for 30 years, I wonder how much more business we'd be doing if we'd hired them earlier.Rebecca HoneaMay 17, 2019
