Looking for a list of free SEO-related Chrome extensions that will help you to work faster and smarter? Then look no further.
I asked the /r/bigSEO community to name their favourite free Chrome extensions.
I received more than 60 suggestions. And some people even took the time to suggest a bunch of extensions (thank you!)
In this post, I’ve consolidated the suggestions and split them into three categories (as I did with our list of the best free SEO tools):
- 23 well-known free Chrome extensions;
- 30 lesser-known free Chrome extensions;
- 14 “freemium” Chrome extensions.
I also added a few of my own favourite extensions to the list, as Google Chrome is my browser of choice, too.
Let’s get started!
We aim to keep this list fresh and up-to-date, at all times. So if you feel we’ve missed any useful free Chrome extensions for SEOs, you can suggest them for inclusion here 🙂
23 Well-Known Free Chrome Extensions for SEOs
Most of these Chrome extensions are very well-known in the SEO community.
In fact, I have approximately 75–80% of these installed myself.
And I would say I use 40–50% of them on a regular basis.
Now, these extensions aren’t all 100% SEO-focussed. But they are all useful for SEO in one way or another.
Here they are (in no particular order):
LinkMiner — Broken link checker that integrates with Ahrefs, Moz, and Majestic (to show metrics for the links that point to 404 pages). All broken links are red, whereas live links are green. And you can export the data to CSV in one click, too.
SEOquake — Web browser extension with a ton of uses. Analyse and extract Google search results, examine internal/external links, uncover on-page issues, check metrics, and much more.
Other similar extensions: SerpWorx (Freemium)
Keywords Everywhere — Adds search volume and CPC data to the websites you already use including Google, Amazon, YouTube, and more. It even shows search volume data within Google Search Console.
Link Redirect Trace — Uncovers all URLs in a redirect chain including 301’s, 302’s, etc. Very useful for finding (and regaining) lost “link juice,” amongst other things.
Other similar extensions: Redirect Path

30 Lesser-Known Free Chrome Extensions for SEOs
Most of these extensions have a much lower volume of users (according to the Chrome Web Store).
But, that doesn’t mean they’re any less useful than the ones mentioned above.
It just means that far fewer people know about them.
For example, one lesser-known extension is FindLinks.
This simple tool highlights all hyperlinks on the page to make them super-easy to see.
Very useful for uncovering rogue/unwanted links on your website(s).
Here are more of the best lesser-known Chrome extensions:
FATRANK — Tells you where the webpage you’re visiting ranks in Google for any keyword/phrase.
It only checks the top 100 results. It will return “not in 100” for websites that don’t rank in the top 100.

14 Freemium Chrome Extensions for SEOs
To get the most out of some Chrome extensions, you must be a paying customer of a particular service.

Chrome extensions can have a huge impact on productivity.
But, installing too many may slow down your browser. So, choose them wisely.
If you use a lot of extensions, you can always create multiple user profiles for different tasks. Then, you can install different extensions on each profile and switch between them as needed.
And finally, if you would like to suggest a Chrome extension to be added to this list in the future, you can do so here.
