You can also quickly export all the headings in a CSV. Now you can easily compare 2 different pages in a spreadsheet.

How is the SEO Pro Extension Better than {Another Tool}?

The SEO Pro extension was inspired by SEO Meta in 1 click which I, Kristina, loved and used every day. 

But it was missing some features (like Schema, status codes and redirect chains, export options, etc.) and the design was not quite usable for me. So I took it as an inspiration and created a new tool that has many more great features to offer. 

Some people also ask how the SEO Pro extension is better than SEOQuake. I haven’t used the latter for a long time. But here’s what other people say:

At the end of the day, you’re free to choose the tool that works better for you. 

What data SEO Pro extension shows in Core Web Vitals?

The extension first checks Field data for a page. 
If Field data does not exist, it checks for Origin Summary info (the aggregate experience of all pages on the website). In this case, all metrics will be the same across all website pages. 
If neither Field data nor Origin Summary is available, the extension does not return any info. You can then use Page Speed Insights to check the lab data.
