Best SEO Chrome Extensions: SEO Extensions for Chrome That Check Pages, Links, Speed and Keywords

Updated October 2026 · Written and maintained by the Progression Agency strategy team

An SEO Chrome extension puts a quick check one click away: titles, headings and canonicals on the page you are looking at, the redirect chain behind a link, whether robots rules block a URL, or keyword data beside Google’s results. This guide organizes the best SEO Chrome extensions by the job each one does, notes which are free and which need a paid account, and explains what each extension’s own store listing says it shows. Extensions are listed from their Chrome Web Store listings and vendor documentation, read in October 2026; we have no affiliate relationships with any of them.

What an SEO Chrome extension can and cannot tell you

An SEO extension is a small program that adds a toolbar button, a side panel or an overlay to Chrome, and shows facts about the page you are on or the Google results you are reading. Whatever the store calls it, an SEO extension for Chrome does one of a few jobs, and the useful question is which job you need done on which page. Searchers also look for a Chrome extension SEO checker when they want the page facts in one panel, and that is the first set below.

What does an extension actually read?

Two kinds of data come out of an extension. The first is read from the page you have open: the title tag, meta description, headings, canonical tag, robots directives, links, image alt text and structured data. That information is exact for the page as your browser received it. The second is looked up by the vendor and shown beside the page: traffic estimates, authority scores, link counts and keyword numbers. Those come from the vendor’s own crawl or model, and nothing in Google’s systems has to agree with them.

Why do extension numbers differ from Search Console?

Google Search Console reports what Google itself recorded for your site: impressions, clicks and the indexing status of a URL. A vendor toolbar can only estimate. Two vendors will show two different traffic figures for the same site, and an authority score from one company is not comparable with another’s. Use extensions to find questions quickly and Search Console to settle them. Our guide to SEO tools for small business covers the Google tools and software platforms that sit behind these checks.

What one page at a time means for your work

Extensions look at one page per click. They suit a spot check of a landing page, a competitor’s title, a redirect that seems wrong or a robots rule that might be blocking a section. They are not a crawler, so they will not find a pattern across ten thousand URLs. A few, such as the SEO Minion and Ahrefs toolbars, add link and broken link checks for a single page, and a separate crawl is the better choice for a whole site.

The best Chrome SEO extensions at a glance

No single extension wins every task, so this guide explains each entry’s job instead of scoring it. The table lists what each store listing says the extension does, the free or paid terms as the listing or vendor states them, and the month the listing was last updated. Use it to shortlist, then read the sections below for the entries that fit the task you have.

Where a row says the listing states no price, the listing gives no tier, so check the vendor’s page before you rely on it. Extensions last updated before 2025 stay in the table with their month so you can judge them.

How do you pick the right one?

Start from the question in front of you. A title that looks wrong calls for an on-page checker. A link that lands on the wrong page calls for a redirect checker. A section that will not index calls for a robots checker. Keyword and link tools come last, because they answer research questions rather than fix questions. Most people end up with three or four extensions that each do one job.

Before you install anything from the table, run through these checks:

• Open the extension’s own Chrome Web Store page, not a link from an email or an ad.
• Read the description and the privacy section, and note the last updated month.
• Read the vendor’s page for what is free and what needs an account.
• Choose the narrowest site access Chrome offers.
• Test it on a page you know well and compare its facts with the page source.

Do these work in Edge or Firefox?

Some vendors say so on their own pages. Ahrefs says its toolbar is also available for Firefox and Safari, Moz offers MozBar for Chrome and Firefox, Keywords Everywhere offers Chrome, Firefox and Edge, Similarweb lists Chrome, Edge, Firefox and Opera, and WebAIM lists WAVE for Chrome, Firefox and Edge. For any other extension, check the vendor’s page rather than assuming it carries over.

Free SEO Chrome extensions worth installing first

A free SEO Chrome extension is only free if its vendor says so, and plenty of tools are free to install but ask for a paid plan once you want their data. These starter picks are ones whose own pages or listings state what is free, with what each is good for. A handful of them covers most spot checks.

• Detailed SEO Extension: the vendor’s page calls it free, and it pulls the title, meta description and meta robots tag for the page you are on.
• META SEO inspector: the listing calls the platform completely free with no account, and it covers metadata, headings, image alt text, social tags and JSON-LD.
• Redirect Path: Ayima’s terms say its extensions are provided free of charge, and it shows status codes, redirect chains and headers.
• Lighthouse: open source, with the same audits also built into Chrome DevTools.
• Keyword Surfer: Surfer’s page describes it as free, and it adds keyword ideas beside Google results.
• Ahrefs SEO Toolbar: the core tools are free; Ahrefs metrics need a paid account.
• MozBar: a free guest level and a free account level; Moz Pro unlocks the rest.
• Similarweb: the vendor’s FAQ says it is free to install and use.

Free tiers change, and a few vendors have moved features behind a plan. SEO Minion, for example, now says it comes with Keywords Everywhere’s Silver, Gold and Platinum plans. Confirm the terms on the page you read, and note the date.

On-page SEO checks: titles, headings, canonicals and schema

Every on-page SEO extension answers the same opening questions: what is this page’s title, how long is it, what does the meta description say, which headings are on the page, and does the canonical point somewhere unexpected. A good chrome extension seo analysis panel lays these out together so you do not have to open the page source, and an on page seo extension is also the quickest way to compare your page with a competitor’s.

Detailed SEO Extension

Detailed SEO Extension is built by working SEOs according to its listing, and it is meant for daily analysis: one click shows the title tag, meta description, meta robots tag and more for the site you are on. It suits a first look at any page, because it surfaces the tags a search engine reads before you open the source code. The store page shows its last update as June 2026.

SEOquake

SEOquake has been around since 2006, says its listing, and offers a Quick View for a compact snapshot and a Full Report for deeper checks of robots directives, hreflang, sitemap availability, image alt text and structured data, plus a keyword density report. An overlay adds Semrush metrics under each Google result, and the listing says core reports and the built-in metrics work without an account. Its store listing was last updated in October 2026.

META SEO inspector

META SEO inspector lists titles, descriptions and their lengths, canonicals, meta robots, headings from H1 to H6, image alt data, Open Graph and Twitter tags and full JSON-LD, with a dockable side panel and a broken link checker. Its listing calls the platform completely free and says there is no account to register, so it is an easy first install. The store page shows its last update as October 2026.

SEO Minion

SEO Minion is a sidebar of twelve tools according to its vendor page, among them an on-page analysis, a broken link check, a SERP preview, a comparison of the source HTML with the rendered DOM and a hreflang checker. The vendor page says it is included with the Silver, Gold and Platinum plans of Keywords Everywhere, so it is a paid plan feature rather than a free add-on. Its store listing was last updated in February 2026.

SEO META in 1 CLICK

SEO META in 1 CLICK shows a page’s title and description with their lengths, the canonical, meta robots, headings in order, how many images have alt text, link counts, social data, and links to robots.txt and the sitemap. Because the listing is from 2024, treat it as a simple reader of meta data and confirm anything important in the page source. The store page shows its last update as August 2024.

Redirects, status codes and robots rules

Redirect and robots problems are quiet ones. A page can look fine in the browser while a chain of redirects slows it, a meta tag asks search engines to skip it or a robots rule blocks the folder it lives in. The extensions below make those hidden signals visible on the page you are viewing. Fixing them is technical SEO work, and these tools are how you find the first leads.

Redirect Path

Redirect Path flags 301, 302, 404 and 500 status codes as well as meta and JavaScript redirects, and it also shows headers such as server type and caching, along with the server IP address. Use it when a link seems to land on the wrong page or a campaign URL loads slowly, because the chain is shown step by step. Ayima’s terms say the extensions are provided free of charge. Its store listing was last updated in May 2026.

Link Redirect Trace

Link Redirect Trace calls itself an all-in-one redirect path analyzer. It also reads protocol headers, canonicals and robots rules at each step, and its listing says it can show whether robots.txt or an X-Robots-Tag blocks crawlers from a redirect. The listing is older, so rely on the redirect path it traces and confirm anything else elsewhere. The store page shows its last update as June 2024.

Robots Exclusion Checker

Robots Exclusion Checker says it reports on six elements: robots.txt, the meta robots tag, AI bots, the X-Robots-Tag header, the canonical tag and the nofollow, UGC and sponsored link attributes. You can pick a search engine user agent in its settings to simulate what that engine is allowed to see, which makes it the clearest check for a page that will not index. Its store listing was last updated in March 2026.

NoFollow

NoFollow outlines nofollow, UGC and sponsored links on the page and detects nofollow and noindex meta tags, with search engine specific robots tags supported. That makes it a quick way to see how a page’s outbound links are marked before you decide whether a link needs a different attribute. The store page shows its last update as September 2026.

Rendering and JavaScript: seeing what Google sees

A page built with a JavaScript framework may send one thing from the server and show another in the browser. The question for SEO is whether the content you can read after rendering is also what a search engine processes. Two tools help: an extension that compares the raw and rendered HTML, and Google’s own URL Inspection tool.

View Rendered Source

View Rendered Source shows the raw source the server sent, the rendered page after the browser has built it and a difference view that highlights, line by line, what JavaScript changed. It is meant for pages built with Angular, React or Vue, and it lets you emulate a mobile user agent. Its last update is old, so confirm it still loads on your version of Chrome before you depend on it. Its store listing was last updated in June 2023.

Chrome DevTools and URL Inspection

You do not need an extension for the second opinion. Chrome DevTools is built in, and Google Search Console’s URL Inspection tool reports on Google’s indexed version of a page. Google’s help page says the tool can show a rendered view of the page, the crawled page code and loaded resources, and that a live test checks whether a URL might be indexable. A rendered-source extension shows what your browser built. URL Inspection shows what Google recorded, and when the two disagree you have found a real problem.

Speed and Core Web Vitals checks

Page speed shapes how a visit feels, and a quick browser check gives you a reading on the page in front of you. If a page keeps failing the checks, the fix is usually in images, scripts and hosting, and our website speed optimization service covers that work.

Lighthouse

Google’s documentation describes Lighthouse as an open source, automated tool with audits for performance, accessibility, SEO and more, and says it runs in Chrome DevTools, from the command line or as a Node module. The same page says to prefer DevTools over the extension unless you have a reason, because DevTools can test local sites and pages that need a login and the extension cannot. The store page shows its last update as June 2026.

What happened to the Web Vitals extension?

Google’s Chrome team ended support for the Web Vitals extension on January 7, 2025. Its blog explains that the extension’s core features moved into the Performance panel of Chrome DevTools, which now shows your local Largest Contentful Paint and Cumulative Layout Shift, and Interaction to Next Paint once you interact with the page. The extension’s store listing no longer loads, so we do not list it. Use the Performance panel instead, and read Google’s announcement for the details.

Keyword and SERP data beside Google results

Keyword extensions put data next to the search results you are already reading. They can show related terms, estimated traffic for each result and People Also Ask style ideas. The numbers are each vendor’s estimates, and the free allowance differs by vendor. This page describes what each listing says the tool shows and does not print figures from any of them.

Keywords Everywhere

Keywords Everywhere is described in its listing as a freemium extension that covers 15 or more sites, including Google, YouTube and Amazon. The vendor’s page says the keyword lists, traffic metrics, link metrics, backlink data and prompt templates are free with no API key, while search volume, cost per click, competition and trend data run on credits, so you pay for the data you pull. The listing also mentions a Search Console visualization. Its store listing was last updated in October 2026.

Keyword Surfer

Keyword Surfer shows keyword ideas and search data in a side panel on Google results, according to its listing, including cost per click, related terms and on-page data. You can store keywords and export collections as a CSV file. Surfer’s own page describes the extension as free. The store page shows its last update as January 2026.

SEO Search Simulator by Nightwatch

SEO Search Simulator by Nightwatch simulates unbiased Google searches from a chosen location so you can check where your site or a competitor’s ranks. Its listing points to the Nightwatch app for people who run many searches and hit rate limits or captchas in a browser. Its store listing was last updated in March 2025.

A fuller keyword workflow also needs Google Search Console and a clear idea of the page each term belongs on. Extensions help you notice terms; they do not decide strategy.

Links and authority metrics

Link extensions show how many pages link to the one you are viewing and score the strength of that profile. The key point is that each score is one vendor’s own measure. Domain Authority is a Moz score, Domain Rating is an Ahrefs score and Trust Flow is a Majestic score, each calculated from that company’s own crawl, so the numbers are not interchangeable.

MozBar

MozBar names three access levels in its listing: a guest level with on-page elements and link details, a free account level that adds Domain Authority and Page Authority, and Moz Pro for Spam Score, page optimization and keyword queries. Moz’s own page calls it a free extension for Chrome and Firefox, with premium features for Moz Pro subscribers. The store page shows its last update as September 2026.

Ahrefs SEO Toolbar

Ahrefs says on its own page that you can sign in free to see Domain Rating and URL Rating, and that a paid account unlocks Ahrefs metrics in the browser. The Ahrefs SEO Toolbar listing also mentions highlighting links, tracing redirects, reading HTTP headers and switching user agents to see a page as Googlebot would. Its store listing was last updated in September 2026.

Majestic Backlink Analyzer

Majestic Backlink Analyzer shows link counts and the Trust Flow, Citation Flow and Visibility Flow scores for the page you are on. Its listing says the link counts and flow scores are free for pages you visit, with speed limits, and that Majestic subscribers can link their account to see backlink and anchor text detail. The store page shows its last update as January 2026.

Similarweb

Similarweb shows traffic over time, traffic sources, AI chatbot referrals, top prompts, top keywords and a site ranking for any website, according to the vendor’s page, which also says the extension is free to install and use. Traffic figures from this kind of tool are estimates, so use them to compare sites with each other rather than as a count of real visits. Its store listing was last updated in October 2026.

Technology and site stack detectors

A technology detector tells you what a site runs on: the CMS, theme, ecommerce platform, analytics and scripts. SEOs use it before a migration, to understand a competitor’s setup or to explain why a site loads the way it does. Our own tech stack page shows what Progression builds with.

Wappalyzer

Wappalyzer identifies the CMS, frameworks, ecommerce platform, JavaScript libraries and more, and its listing says results can be exported to CSV. Wappalyzer’s pricing page says a free account includes 50 lookups and email verifications a month, so check its plans before you plan heavy use. The store page shows its last update as October 2026.

BuiltWith Technology Profiler

BuiltWith Technology Profiler returns all the technologies BuiltWith can find on the page you are viewing, according to its listing. Treat the old update date as a reason to compare any surprising result with the page source. Its store listing was last updated in May 2022.

Accessibility checks that overlap with SEO

Accessibility and search share ground: clear headings, descriptive link text, alt text on images and a readable page structure help screen reader users and search engines alike. Automated accessibility checkers cannot say a page is accessible, but they catch the common errors fast. If your site needs a full review, our ADA compliant website design page explains the standards.

WAVE Evaluation Tool

WebAIM says the WAVE Evaluation Tool extension runs entirely inside your browser and sends no information to the WAVE server, which lets it check intranet and password-protected pages. The listing says WAVE errors align with WCAG 2.2 failures and adds that no automated tool can tell you if a page is accessible. The store page shows its last update as May 2026.

Accessibility Insights for Web

Microsoft’s page describes Accessibility Insights for Web as an extension for Chrome and the new Microsoft Edge with a FastPass for common high-impact issues, automated checks for about 50 requirements, a tab stops tool for keyboard access and an assessment that guides you through WCAG 2.1 AA. The same page says the tool is open source. Its store listing was last updated in September 2026.

Search Console, YouTube and international checks

A few extensions are narrow on purpose. They add a feature to Google Search Console, support a marketing platform you already use or check one thing such as hreflang. Narrow tools are worth having when you do that one thing every week.

Google Search Console Enhanced Analytics

Google Search Console Enhanced Analytics adds date comparison, percentage changes, search volume generation and an Excel export to Search Console reports. Its listing says it needs no access to your Search Console property, stores no data, and keeps any DataForSEO credentials you choose to save in your own browser. The store page shows its last update as September 2026.

Conductor for Chrome

Conductor for Chrome brings page performance insights, topic opportunities and keyword research into the browser. The listing calls it free for all marketers and says it is available to anyone with a Conductor or Google account. Its store listing was last updated in June 2026.

Hreflang checks

Hreflang tags tell Google which language and region a page is for, and they have to point at each other. The Hreflang Validator listing describes checks for language and country codes, trailing slash mismatches, redirects and canonical conflicts. The listing was last updated in October 2024 and the extension is a small, single-purpose tool, so treat it as a helper. SEO Minion, MozBar and the Ahrefs toolbar also say they cover hreflang, and you can inspect the tags in the page source by searching for hreflang. For a site that serves several countries, see our international SEO page.

YouTube SEO extensions

The listings read for this guide do not include a tool built only for YouTube, so no dedicated YouTube SEO extension is recommended here. Keywords Everywhere’s listing does mention YouTube search insights, video insights and tags, and your own channel analytics show how viewers find your videos. For titles, descriptions, chapters and search on the platform, see YouTube SEO.

Are SEO Chrome extensions safe to install?

Most are, but an extension is software that can read the pages you visit, so a careless install is a real risk. Chrome’s own help page tells you to approve only extensions you trust. Treat every SEO Chrome extension the way you would treat any program on a work computer.

Permissions to read before you click Add

Chrome shows the permissions an extension requests in a dialog, and the Chrome Web Store help page explains how to review them later. You can set an extension to run only when you click it, on one site or on all sites, and you can allow or block incognito use. The Chrome Web Store program policies tell developers to request the narrowest permissions necessary and to limit user data to a disclosed single purpose. Read the program policies once so you know what a developer owes you, then prefer the narrowest setting for every extension.

Extensions that stop being updated

Browsers change, and stale extensions break. Chrome’s help page warns that Chrome may disable extensions that do not meet current requirements. Google’s Manifest V2 timeline shows how large a shift can be: Manifest V2 extensions were disabled for all users with Chrome 138, and Google’s page says all remaining Manifest V2 extensions were removed from the Chrome Web Store on August 31, 2026. The updated month in the table above is a simple health signal, and a listing that has not changed in years deserves a second look before it touches client work.

Keeping client data out of extensions

An extension that adds vendor metrics to a page has to ask the vendor about the page you are viewing, so read each listing’s privacy section before using it on logged-in client pages, analytics or a CMS dashboard. WebAIM states that the WAVE extension sends no information to its server, and Ayima’s listing says Redirect Path does not contact anyone except to update itself, which is the kind of statement to look for. A separate Chrome profile with only the extensions you need keeps client sessions apart from everything else.

From extension checks to a real SEO fix list

Extensions find things quickly, and they often find more than one person can fix. Fifty pages with missing descriptions, a redirect chain on the home page and a robots rule nobody remembers adding are all useful findings, but they are not yet a plan. An SEO Chrome extension shows a symptom; an audit explains the cause, ranks it and says who fixes what. The flow below is how we usually move from a quick check to a list, and our guide to SEO tools for small business covers the free Google tools that confirm each step.

A useful fix list is short enough to act on. For each finding, write down:

• The URL, or the template, where the problem appears.
• What the extension showed, and what Search Console shows for the same page.
• Why it matters: blocked from indexing, slow, duplicated or just untidy.
• Who can change it: the person who edits the page, the developer or the hosting provider.
• How you will know it is fixed, such as the same check coming back clean.

When is it time to hire help?

Bring in an expert when the findings span templates rather than single pages, when Search Console shows pages excluded for reasons you cannot trace, or when traffic has dropped and the checks do not explain why. A written SEO audit covers crawl, indexing, content and links in one review, and ongoing work then sits under our SEO services.
