Looking for a list of free SEO-related Chrome extensions that will help you work faster and smarter? Then look no further.
This is not a random list of extensions. We’ve tested all of these tools and found them worthy of your attention. We also use a lot of them in our everyday work here at Ahrefs.
The list contains 26 extensions, so we split them into categories for your convenience.
Let’s start at the top.
Use these extensions to improve your webpages.
This extension looks for SEO issues on the page, tells you how many there are, and lets you investigate further. The check covers meta tags, canonicals, indexability, Open Graph tags, structured data, hreflangs, page speed, and more.
It also has a built-in Audit module that uses Google’s Pagespeed Insights API.
Despite its name, this tool has nothing to do with incoming links. It analyzes the outgoing links on a page. Like many other link checkers, it highlights all broken links red and live links green. It can also export all links on a page to a CSV or XLSX file along with their anchor text, HTTP status, and “rel” attribute for further analysis.
Unlike many other broken link checkers, this one allows you to increase the time delay between link requests for slower page analysis. This prevents many false positives caused by server protection.
Although lots of extensions show hreflang data, this one is more advanced. It crawls the URL’s hreflang tags to check if they have return links.
Use these extensions to find and research keywords.
Generates thousands of keyword ideas from a seed keyword by scraping autocomplete suggestions from Google, Youtube, Bing, Yahoo, Amazon, and eBay. If you’ve ever used Keyword Sheeter, you’ll already be familiar with the concept. All data can be exported to CSV.
TextOptimizer describes itself as a writing assistant tool. It analyzes search results for relevant terms and extracts “intent tables” to suggest other words that you can use in your copy “to better match search engines’ expectations.”
Keyword research and SERP analysis tool. It gives away an insane amount of data for a free tool: domain-level traffic estimations in the search results, keyword volumes (both local and global), keyword suggestions, and domain-level backlink counts.

Use these extensions to improve your site from a technical standpoint.

11. AMP Validator
Checks if a page has an AMP version (Accelerated Mobile Page). The tool then runs the AMP validator to see if the page passes or fails.

Other similar extensions: Structured Data Testing Tool
Mimics user-agents to check that your website displays correctly in different browsers and OS’.

There are quite a few Chrome extensions that bring the features of online SEO tools and services right into your browser. I hope that this post helped you to find an extension or two that will have a significant impact on your productivity and will save you lots of time.
Just keep in mind that using too many browser extensions may slow down your computer. 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.
You can also use One Click Extensions Manager to keep your extensions neat and orderly.
