For most people, the best SEO Chrome extensions in 2026 are Ahrefs SEO Toolbar and Detailed SEO Extension for checking pages, Check My Links by SelectorsHub for broken links, and GMB Everywhere for Google Business Profile work. All four were live and rated 4.5 or higher when we checked them on November 9, 2026.
Many older lists are out of date. Chrome removed all remaining Manifest V2 extensions from its store on August 31, 2026, and that took some long-time favorites with it. Others are still listed but now sit behind a paid plan. This guide shows what changed and what to install instead.
Which SEO extensions broke, vanished or went paid
These are the changes most likely to affect you if you've used SEO extensions for a few years.
| Extension | What happened | Use instead |
|---|---|---|
| Check My Links (Logflare) | Removed on August 31, 2026. It had 70,000 users and was last updated in 2020. | Check My Links by SelectorsHub |
| LinkMiner | No longer listed in the Chrome Web Store. | Ahrefs SEO Toolbar, which also spots broken links |
| Web Vitals (Google) | Support ended in January 2025 and its features moved into Chrome DevTools. | The DevTools Performance panel, or Core Web Vitals Visualizer |
| SEO Minion | Still listed, but it needs a Keywords Everywhere Silver plan or higher. Rated 1.6. | Detailed SEO Extension or META SEO inspector |
| MozBar | Rebuilt as version 5 and still listed. Rated 1.4 from about 2,500 ratings. | Keep it if you need Moz's Domain Authority. Otherwise, Ahrefs SEO Toolbar |
| MagicBrief (ad saving) | Reported as discontinued on July 31, 2026, and no longer listed. | Foreplay, a paid ad library tool |
SEOquake belongs in a different group. It had a rough patch, but it's still here with 1,000,000 users, an update on November 6, 2026, and a listing that says its search results overlay is back. It's rated 3.6, so you may want to try it before you replace it.
How the current extensions compare
We read the Chrome Web Store listing for each extension on November 9, 2026, and used Chrome-Stats to confirm the removal date for Check My Links. These are lifetime store ratings, so they include old complaints, and some come from a small number of people. We compared listings and did not test paid features.
The gap at the bottom of the chart is hard to miss. MozBar and SEO Minion sit below 2.0, and Keyword Surfer is at 2.7 from about 1,100 ratings. A low rating doesn't always mean a tool is useless, but it does mean you should read the newest reviews first.
Why your SEO extension stopped working
If an extension you've relied on has gone quiet, the most likely reason is Manifest V2, the older format Chrome extensions were built on. On Chrome 139 and later, these extensions no longer run at all. Once one is removed from your browser, you can't reinstall it from the store.
The fix takes a few minutes:
- Type
chrome://extensionsinto your address bar and look for anything turned off or flagged. - Remove the ones that no longer work, so they don't clutter your toolbar.
- Install a replacement from the table above.
- Check the developer name and last update date on the listing before you add it.
That last step matters more than it sounds. There are now two extensions that have been called Check My Links, from two different developers. An old review praising one tells you nothing about the other.
The best SEO Chrome extensions by job
Checking a page: Detailed SEO Extension
Detailed SEO Extension shows a page's title tag, meta description, robots tag and other basics in one click. It has about 600,000 users and a 4.8 rating from 234 people. The store lists Ahrefs as its developer, so this pick and the next one come from the same company.
Links, redirects and more: Ahrefs SEO Toolbar
Ahrefs SEO Toolbar covers on-page checks, highlights links, traces redirects, spots broken links and exports the results to CSV. You can also switch user agents to see a page as Googlebot would. It has 400,000 users and a 4.7 rating. Those tools are free, while Ahrefs' own metrics need a paid account. If you want a second opinion on page data, META SEO inspector is free to install, with 200,000 users and a 4.3 rating.
Broken links on one page: Check My Links by SelectorsHub
This is the closest match for anyone who used the original. It scans a page, flags broken links, and can now check links in Google Docs and Sheets too. It has 90,000 users, a 4.6 rating and an update from October 31, 2026.
Broken links across a whole site: Checkbot
Checkbot crawls more than one page and also looks at speed and security. It's rated 4.9 by 956 people, the highest score in our comparison, and its listing says the free version covers small websites. Its last update was January 14, 2025, so keep an eye on how actively it's maintained.
Page speed: Chrome DevTools
You may not need an extension here. Google moved the Web Vitals features into the DevTools Performance panel, so they're already in your browser. If you'd rather see problems marked on the page itself, Core Web Vitals Visualizer has 10,000 users and a 4.9 rating, though only 19 people have rated it.
Google Business Profile: GMB Everywhere
For local businesses, this is the one to know. GMB Everywhere shows a listing's categories on Google and runs basic audits of profiles, reviews and posts, which makes it handy for seeing what nearby competitors are doing. It has 300,000 users, a 4.5 rating and an update from November 2, 2026. Check which features are free before you build it into your routine.
What these tools can't tell a local business
An extension shows you what's on one page. It can't tell you whether that page brings in calls, or why a competitor is ahead of you in the map results.
It's still good at catching simple mistakes. When we checked 92 small contractor homepages, 41% didn't name a town or city in the page title or main heading, and 16% had no meta description. Detailed SEO shows you both in one click.
Once your page basics are clean, the next step is your profile and reviews. Our guide on improving your Google Maps ranking walks through the order to do things in, and our free tools cover things like watching for lost Google reviews.
Frequently asked questions
What is the best free SEO Chrome extension?
Detailed SEO Extension is the simplest choice for checking a page, and it's rated 4.8. Ahrefs SEO Toolbar does more, including broken link and redirect checks, and its core tools are free.
What happened to Check My Links?
The original Check My Links by Logflare was removed from the Chrome Web Store on August 31, 2026, the same day Chrome removed its remaining Manifest V2 extensions. It hadn't been updated since 2020. A separate extension with the same name from SelectorsHub is still available.
Is MozBar still available?
Yes. MozBar is still in the Chrome Web Store and was rebuilt as version 5, but it's rated 1.4. It's mainly useful if you specifically want Moz's Domain Authority score, so check what your Moz account includes.
Why are my Chrome extensions disabled?
Most often, they were built on Manifest V2, which no longer runs on Chrome 139 or later. Open chrome://extensions to see which ones are affected, then install a current replacement.
Do SEO Chrome extensions help a site rank?
Not directly. They only show you information. Rankings improve when you act on what they find, such as fixing a broken link or giving a page a clearer title.
Keep your toolbar short
You probably need two or three of these, not ten. Install one page checker, one link checker and, if you run a local business, GMB Everywhere. Then spend your time fixing what they find.
If you'd like someone to find those problems for you, look at our technical SEO services or request a free audit.
