22 Chrome extensions to boost your SEO

What's more convenient than SEO tools built right into your Chrome browser?

SEO (search engine optimization) helps drive more organic traffic to your website by ranking your pages higher for relevant queries in search engines, predominantly Google but others too.

SEO still very much matters. Organic search consistently drives more traffic than any other channel, and the extensions below let you check rankings, research keywords, and audit pages without ever leaving your browser tab.

While you're thinking about your own website's SEO, it's worth understanding the difference between on-page and off-page SEO, since the tools below split fairly cleanly across both.

Chrome extensions are tools built into your browser that help you work faster and smarter. Put the two together, and you get a little SEO magic.

We refreshed this list for 2026: a few of the original tools were discontinued, renamed, or moved behind a paywall, so we swapped in current, actively maintained replacements and updated every link. Here are 22 Chrome extension recommendations to help boost your website's SEO.

Four categories of SEO Chrome extensions: rank checking, keywords, on-page, and technical SEO
Today's SEO extensions generally fall into four workflows: rank checking, keyword research, on-page audits, and technical checks.
Recommended

Chrome retired support for old Manifest V2 extensions, so a few once-popular SEO tools have quietly stopped working. Check each listing's "Updated" date and permissions before installing, and prefer extensions that are actively maintained.

SEO rank-checking extensions

SEO Search Simulator by Nightwatch

The SEO Search Simulator by Nightwatch extension emulates Google searches to check if a particular URL ranks in the top 100 results.

These Google searches can be run from any of over 107,000 supported locations, so you can see how rankings vary in different parts of the world without a VPN.

SERPTrends SEO Extension

The SERPTrends SEO Extension tracks your Google, Bing and Yahoo searches. Over time, as you repeat queries, you'll see trends and ranking movements directly in the search results.

Included in the data shown:

  • Whether a website moved up or down in the search results
  • When a website is ranking for the first time or hasn't changed position
  • How many positions a website lost or gained compared to your previous search

SEOquake

SEOquake, from Semrush, gives you a detailed overview of any website, including indexing information for Google and Bing, plus a full SEO audit of the current page. No Semrush account is required to use the core features.

The extension lets you dive deeper with a keyword-density report or an overall diagnosis report that breaks down on-page SEO elements for any web page.

Keyword-research extensions

Keywords Everywhere

Keywords Everywhere is a freemium extension used by more than 1.6 million marketers. It shows keyword search volume, CPC and competition data directly inside search results on:

  • Google
  • YouTube
  • Amazon
  • Bing and 10+ other sites

Free users get related keywords and "people also search for" suggestions, while paid credits unlock full search volume, CPC and SEO difficulty data.

Ubersuggest

The Ubersuggest extension, built by Neil Patel, shows keyword monthly search volume, CPC and competition data. You can find related keywords and information within search result pages on Google, YouTube and Amazon, and export data to a CSV file.

TextOptimizer

The TextOptimizer extension is a writing assistant that helps you write concise, high-quality, targeted content that reads well for people and is optimized for search engines.

It works by analyzing search results for relevant terms and extracting "intent tables," recommending other words you can use in your copy to better match what search engines expect to see.

Keyword Surfer

The Keyword Surfer extension, built by Surfer SEO, is a keyword research and SERP analysis tool used by over 700,000 people daily. The data it offers includes, but isn't limited to:

  • Domain-level traffic estimations in Google Search results
  • Keyword volumes, locally and globally, across 70 countries
  • Keyword suggestions and related terms
  • Domain-level backlink and word-count data for ranking pages

You can also set up a content editor and start creating right away: researching, writing, and optimizing without ever leaving Google Search.

Five-step SEO workflow: research, optimize, fix, build, monitor
A typical SEO workflow moves from keyword research through on-page and technical fixes to link building and ongoing rank monitoring.

On-page SEO extensions

SEOInfo

SEOInfo audits your website pages, reporting any SEO issues and letting you dig deeper. Specifically, the extension examines:

  • Meta tags and canonicals
  • Indexability and Open Graph tags
  • Structured data and Core Web Vitals
  • Page speed, via the Google PageSpeed Insights API

The Free Backlink Checker by LRT extension analyzes the outgoing links on a page, rather than incoming links from other websites.

It highlights broken links in red and live links in green. For further analysis, you can export all links on a page to a CSV or XLSX file, along with their:

  • Anchor text
  • HTTP status
  • The "rel" attribute

To prevent false positives caused by server protection, you can increase the delay between link requests, which slows the analysis but improves accuracy.

Hreflang Checker

The Hreflang Checker extension analyzes any webpage's hreflang tags in one click, catching the errors that can cost you global rankings. It validates return links, language and region codes, canonical consistency, and self-referencing tags, and it works with JavaScript-rendered hreflang on single-page applications.

This supports your site's language targeting and hreflang architecture, giving you a fast, reliable read on how well your site is optimized for international organic search.

Technical-SEO extensions

Link Redirect Trace reveals all the URLs in a redirect chain, including 301s, 302s and JavaScript redirects. It's considered an all-in-one redirect path analyzer.

A typical backlink profile usually includes redirects from other websites, and this tool helps you check whether those redirects are SEO-friendly or are quietly harming your website.

Google Lighthouse

Google Lighthouse audits your page and suggests improvements related to:

  • Performance
  • Accessibility
  • Developer best practices
  • SEO

The extension runs a battery of tests against the page and generates a report on how well it performed. You can use any failing tests as a checklist for what to fix next.

AMP Validator

The AMP Validator extension, built by Google, checks whether a page has an AMP (Accelerated Mobile Page) version. The page then runs through the validator, which reports whether it passes (green) or fails (red) directly on the extension icon.

Worth noting: AMP is no longer a direct Google ranking factor, so treat this as a maintenance tool for existing AMP pages rather than a reason to build new ones.

The OpenLink Structured Data Sniffer discovers metadata embedded in HTML documents as structured data, including Microdata, RDFa, JSON-LD and RDF-Turtle, and presents what it finds in a clean property-sheet view.

It simplifies understanding what a given HTML document is about for both end users and developers. For a deeper look at why this matters, including how AI answer engines use the same markup, see what structured data is and how to use it.

View Rendered Source

See how the browser renders a page, not just what the server sends, with the View Rendered Source extension. This is a must-have for anyone working with JavaScript-powered websites, since it compares the raw page code against the rendered version.

With this tool, you can see whether JavaScript is overwriting your meta tags, for example, or hiding content from search engines.

Link-building extensions

Linkclump Plus

The Linkclump Plus extension lets you open, copy or bookmark multiple links at once. Drag a selection box around links with your mouse to quickly open them as new tabs, open them in a new window, save them as bookmarks, or copy them to your clipboard.

This is a Manifest V3 fork of the original Linkclump, built to keep working as Chrome phases out older extensions, and it can be a big help during link prospecting.

BuzzSumo

The BuzzSumo extension shows how many social shares, links and top-performing pages a website has, right from the SERPs or any page you're browsing.

A BuzzSumo account with an active trial or subscription is required to unlock full data, but it's a strong way to spot outreach targets and content ideas at a glance.

Similarweb

The Similarweb extension shows website traffic and key metrics for any site, including engagement rate, traffic ranking, keyword ranking and traffic sources. It now also breaks out how much of a site's traffic comes from AI chatbots like ChatGPT, Gemini and Perplexity.

This is especially helpful for evaluating link and partnership opportunities before you invest outreach time in them.

Hunter

With the Hunter extension, you can find who to contact when you visit a website.

Along with email addresses, you can get names, job titles, social profiles and confidence scores, each with its public source listed in the results. This can help you reach the right people while you're link building for your own website.

All-in-one SEO extensions

Ahrefs SEO Toolbar

The Ahrefs SEO Toolbar is free and trusted by over 360,000 SEO professionals. It includes an on-page SEO report, a redirect tracer, a broken-link checker, and a nofollow-link highlighter, plus region and language switching so you can research global SERPs without a VPN.

The core tools stay free. A paid Ahrefs subscription unlocks page, domain and keyword metrics directly on visited URLs and search results.

MozBar

The MozBar extension gives you instant metrics while viewing any page or SERP, including the ability to:

  • Create custom searches by engine, country, region or city
  • Quickly assess the Domain Authority and Page Authority of any site or page
  • Access and compare link metrics across pages while viewing any SERP
  • Find and highlight keywords on a page and tell links apart by type
  • Expose page elements, general attributes, markup and HTTP status

A free Moz account unlocks Domain Authority and Page Authority; a Moz Pro subscription adds Spam Score, Page Optimization scoring and keyword-ranking queries.

SEO Minion

SEO Minion helps with daily SEO tasks such as on-page SEO analysis, broken-link checking, hreflang validation, and SERP preview.

Warning

SEO Minion is currently gated behind Keywords Everywhere's Silver plan or higher. It's still a solid toolkit if you already use Keywords Everywhere, but it's no longer usable for free on its own.

In conclusion

There's no single perfect tool, or Google Chrome extension, to serve every SEO need. It's worth auditing your priorities for your website's SEO, then looking through this list, identifying your top candidates, and experimenting with the extensions that seem most promising.
