SEO-related Chrome extensions can help you work faster and smarter. 

I’ve tested a few dozen popular free Chrome extensions and included 14 of the most useful ones in this article.

This extension allows you to inspect the meta information on webpages, find issues, and get advice to fix them. It covers meta tags, canonicals, Open Graph tags, structured data, hreflang, subheaders, and more.

It also provides advanced data about the internal and external scripts used on the page.

Meta SEO Inspector

Unlike many other extensions, Hreflang Tag Checker does not simply list a page’s hreflang data. It actually crawls the links in hreflang tags to check if they link back to the page you’re visiting.

Use our free Ahrefs Webmaster Tools for auditing your whole website for hreflang and other SEO-related issues.

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.”

There are more than enough premium content optimization tools on the market, but TextOptimizer does a good job as a free tool.


This extension gives away a good amount of data for a free tool: Keyword search volumes, keyword ideas, and domain-level traffic estimations are provided straight on Google’s SERPs.

Recently, it added a new feature called “Outline Generator.” This feature creates an article outline by analyzing the top-ranking search results in one click.

Keyword Surfer

The SEO Minion extension is one of the multi-tools for SEO. It allows you to check on-page SEO data, highlight outgoing links, and check pages for broken links.

Arguably, its best feature is the multilevel “People Also Ask” query export from the SERP. This will provide you with related long-tail queries that you can consider when creating a new piece of content.

With this extension, you can emulate Google searches from any location and check if a particular URL ranks in the top 100 results.

This will help you see how rankings vary for a query in different parts of the world.

SEO Search Simulator

Link Redirect Trace uncovers all URLs in a redirect chain, including 301s, 302s, and JavaScript redirects.

Besides, it displays some page-level metrics from LinkResearchTools at no cost.

The Glimpse Chrome extension turns Google Trends into a keyword research tool. It enriches Google Trends data with keyword search volumes, long-tail keyword suggestions, and a topic map.

However, you should note the free version allows only 10 searches per month. You’ll also need a paid subscription for extensive keyword research.


This is a must-have tool for those who work with JavaScript-powered websites.

It compares the raw page code and its rendered version. And SEOs can check, for example, if JavaScript overwrites titles, descriptions, or canonical tags.

View Rendered Source

With Similarweb for Chrome, you can check estimated traffic, traffic sources, visitor geography, and other key statistics for any website.

This extension is useful for evaluating link opportunities and analyzing your competitors.


This extension from Hunter finds email addresses associated with the website that you’re visiting. You get 50 free credits per month. There’s also a Google Sheets add-on for fast bulk-checking.

Gmass is a powerful and lightweight tool for organizing outreach campaigns. It integrates straight into Gmail and requires no additional resources.

It allows you to schedule emails, send mail merges with Google Sheets, create email sequences, and track email opens.


Data Scraper allows you to extract various data from any webpage and save it onto a spreadsheet.

You can extract tables and lists, get paginated results, and create custom scraping “recipes” for your needs.

Our very own toolbar can easily replace a bunch of other SEO extensions for Chrome. 

It offers the following features: on-page SEO report, redirects tracer, HTTP headers reader, link checker/highlighter, and search location simulator.

Ahrefs users also get page, domain, and keyword metrics for the URLs they visit and for search results. Besides, this extension can help you send URLs to Link Intersect and Content Gap reports easily.

Final thoughts

There are quite a few Chrome extensions that bring the features of online SEO tools and services right into your browser. I hope this post helps you 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 the One Click Extensions Manager to keep your extensions neat and orderly.
