79 Best Chrome Extensions For SEO

Last updated on July 31, 2021.

A list of 79 Chrome SEO extensions together with descriptions, screenshots and download links.

Here is probably the longest list of SEO Chrome extensions. It took me more than a week to compile this list and select the best extensions for you. I’ve personally tested each and every SEO extension from the list.

I almost killed my computer while testing these extensions because at one point I had almost 80 active extensions and 100+ tabs open. That’s why, even though all of these extensions are cool, I do not advise installing and actively using all of them.

Check my list of SEO audit tools and Google SEO tools as well.
