I’ve curated the best SEO Chrome extensions into one handy article. Whether you need to audit on-page content, do fast SEO analysis, research keywords right on the SERP, or troubleshoot technical issues, these SEO extensions for Chrome can seriously streamline your workflow.

You’ll see which extensions are best for quick wins and how they save you time (and headaches) in daily SEO tasks. Let’s dive in!

The best SEO Chrome extensions: category-by-category

Ready to turbocharge your browser for SEO? We’ve organized the top Chrome extensions for SEO into categories so you can find exactly what you need. From on-page content optimization to technical SEO fixes, we’ve got you covered with these SEO extensions Chrome users swear by.

On-page SEO and content structure (Chrome extensions for SEO content)

When it comes to optimizing content, these extensions give you instant page-level insights. Use them to spot gaps in metadata, outline content structure, and make sure your pages meet SEO best practices.

1. Detailed SEO Extension

Best for: instant page-level insights, meta tags, headings, schema markup

This all-in-one extension is like an on-page SEO Swiss Army knife.

With one click, Detailed SEO Extension reveals the page’s title tag, meta description, canonical, and robots tags, plus all headings (H1 through H6). It even shows the number of images and links, and has a handy Schema tab to check for structured data on the page.

Why you’ll love it: It saves you from digging through HTML source – you get an audit of key on-page elements at a glance.

For example, you can quickly verify if a page has an <H1> tag or if the meta description is missing. It’s perfect for content audits and ensuring nothing critical slips through the cracks – the kind of detailed seo review you’d otherwise do by reading source code line by line.

2. SEO Meta in 1-Click

Best for: Fast meta info inspection with key elements in one pop-up

As the name implies, SEO Meta in 1-Click gives you all the meta and header information for a page in a single click.

A popup shows the page’s title, meta description, OG tags, Twitter card data, and alt text – handy when planning image link building that relies on clean, descriptive media. It also lists all headings (H1, H2, etc.) and the number of images with or without alt text.

Use case: When you need to do a quick on-page SEO check (e.g., make sure a blog post has a meta description and only one H1), this Chrome extension for SEO makes it effortless.

It doesn’t modify anything – the pop-up simply surfaces what you’d hunt for in source code, but faster.

3. HeadingsMap

Best for: Outlining your heading structure to avoid thin content issues

Struggling with messy heading structures? HeadingsMap comes to the rescue by generating a clear outline of all headings on a page (H1 through H6) in their hierarchical order.

You can instantly see if an <H2> is missing or if you have multiple <H1> tags (oops!). This helps ensure your content is well-structured for both readers and search engines.

Why it’s important: A logical heading hierarchy is crucial for SEO – it helps Google understand your content and also improves accessibility.

HeadingsMap gives you that bird’s-eye view in Google Chrome, so you can reorganize or add headings as needed to fix thin content or hierarchy problems.

What are the best SEO Chrome extensions for technical SEO?

Technical SEO issues can hide below the surface, but these Chrome extensions will help you quickly identify what to fix without spinning up a full crawl.

From redirect chains to header responses, they turn complex technical checks into a one-click task.

4. Redirect Path

Best for: Surface status codes, redirect chains, and HTTP headers quickly

Redirect Path (by Ayima) is a must-have for technical SEO.

Click the extension on any page, and it instantly shows the HTTP status code (200, 301, 404, etc.) and any redirect hops that occurred. This makes it dead simple to find redirect chains or loops without crawling the whole site.

It also displays important HTTP response headers like cache-control or server type.

Why you need it: When a page isn’t loading as expected or you suspect redirects are slowing things down, Redirect Path lights the way.

It’s especially useful after site migrations – you can quickly verify that 301s are in place and not creating daisy-chains that hurt crawl efficiency.

5. Link Redirect Trace

Best for: Visualizing redirect hops and canonical/robots signals

Think of Link Redirect Trace as Redirect Path on steroids. It not only shows the redirect chain, but also fetches SEO signals for each hop: rel=canonicals, robots.txt blocks, meta robots tags, even backlink counts for URLs in the chain.

The extension gives a visual flow of the redirect path from start to finish. It’s specially useful in advanced technical audits where you need to ensure no link juice is leaking.

For example, if an old URL redirects to a new page, Link Redirect Trace will show you if that new page has a canonical pointing somewhere else – a sneaky issue that could confuse crawlers.

It’s an all-in-one technical SEO extension for Chrome when you want a fuller picture of URL behavior, including which hops might dilute equity or surface unexpected nofollow links.

What are the best SEO Chrome extensions for JavaScript rendering and source parity?

JavaScript-heavy websites can be an SEO black box. These Google Chrome extensions help you compare how Google sees your page versus what users see in their browser, so you can close any gaps caused by client-side rendering.

6. View Rendered Source

Best for: Compare raw vs rendered DOM for hidden content

When a page’s content is generated by JavaScript, View Rendered Source becomes a lifesaver.

It loads two versions of the code: the original HTML and the rendered HTML after JS execution. It then highlights the differences.

This means you can spot content that only appears after rendering (like lazy-loaded product listings or client-side injected text).

Why it matters: Googlebot may not see content that isn’t in the initial HTML, especially if rendering fails.

With this extension, you can verify if crucial keywords or links are present in the raw source or only injected later.

It’s perfect for debugging JS SEO issues so search engines and users get the same experience – and ensure that client-side rendering (CSR) isn’t holding back your organic performance.

7. Lighthouse

Best for: Baseline performance, accessibility, and SEO checks

Lighthouse is Google’s open-source auditing tool, conveniently available as a Chrome extension. Run it on any page to get a report card on Performance, Accessibility, Best Practices, and SEO.

It simulates a mid-tier mobile device and throttled network to spotlight things like slow load times, render-blocking resources, or missing meta tags. SEO-wise, Lighthouse will alert you to basic issues (e.g., images without alt text, improper heading nesting, or lack of HTTPS).

In Google Chrome, Lighthouse turns into a quick panel of seo insights (key metrics you can act on immediately): speed metrics (First Contentful Paint, etc.), mobile-friendliness, and even an SEO score. Use it to catch glaring problems quickly and as a guide for further investigation.

8. Web Vitals & CLS Visualizer

Best for: Diagnose layout shifts and site speed metrics

Core Web Vitals are crucial for user experience (and Google’s Page Experience signals). This extension (actually a combo of Google’s Web Vitals extension and a CLS Visualizer) provides real-time feedback on a page’s vitals.

As you browse, it displays metrics like LCP (Largest Contentful Paint), FID (First Input Delay), and CLS (Cumulative Layout Shift).

The CLS Visualizer specifically highlights elements that jump around the page (layout shifts) by outlining them in red as they move.

How this helps: Instead of guessing why your CLS score is poor, you’ll see exactly which banner or image is causing that jarring shift.

Similarly, you can monitor if your optimizations are improving LCP in real time. This is a fantastic Chrome extension for SEO specialists focused on page experience and performance.

What are the best SEO Chrome extensions for backlinks and crawlability checks?

These Google Chrome extensions make link audits and crawlability checks a breeze, so you can keep link equity flowing and ensure nothing is inadvertently blocking crawlers.

9. Check My Links

Best for: Find broken links on a page in seconds

Instead of clicking every link on a page, fire up Check My Links.

This extension quickly crawls all links on the current page and highlights them: usually green for valid links and red for broken ones.

It’s a huge time-saver for content audits or when revising older pages – you can instantly spot outbound links that return 404s or any internal links that need updating.

Pro tip: Run Check My Links on your important pages (like your homepage or hub pages) to catch broken links that could hurt UX and SEO. It saves you from relying solely on periodic crawl reports – you can fix issues on the fly.

10. NoFollow

Best for: Identify nofollow, UGC, sponsored links and page directives

The NoFollow extension shines a light on links that search engines won’t follow. It outlines nofollow links on the page with a red border, so you can quickly identify which URLs won’t pass equity.

Many versions of this plugin also indicate meta tags or headers that affect indexing (like noindex or nofollow directives in the HTML).

This is excellent for a quick crawlability review.

For example, if a page isn’t indexed, you can click NoFollow to see if perhaps a noindex tag or X-Robots header is present (many such extensions will flag it).

It also helps in evaluating user-generated content or external links – are they properly marked as nofollow/sponsored? In one glance, you’ll know which links might not be passing PageRank.

11. Link Grabber

Best for: Export all page links for quick internal linking passes

Need to analyze a page’s internal linking or scrape all URLs listed on a resource page? Link Grabber does exactly that: it extracts every hyperlink on the page and presents them in a list (with options to copy or download).

This is super useful for tasks like: gather all product links on a category page for a crawl, quickly see all outbound links on a guest post, or generate a list of URLs to feed into another tool.

It basically spares you from manually viewing page source or using a crawler for small jobs. It’s ideal when you need all page links from a website in seconds.

Pair Link Grabber with a spreadsheet and you can perform fast internal link audits or build a list of target URLs for outreach.

What are the best SEO Chrome Extensions for SERP research and competitive Context?

Level up your keyword research and competitive analysis without leaving the SERP. These extensions overlay valuable data – like search volumes, related terms, and domain metrics – right onto Google search results pages.

12. Keyword Surfer

Best for: Related keywords, search volume, and on-SERP content ideas

When you perform a Google search with Keyword Surfer enabled, you’ll see extra info directly in the results: approximate search volumes for your query, CPC estimates, and a sidebar of related keywords with their volumes.

Keyword Surfer is like having a mini keyword research tool inside your search results. The extension also suggests content guidelines (like how many headings or images top pages use).

Why use it: It’s fantastic for brainstorming on the fly. If you search a term and want to quickly gauge its popularity or find long-tail variations, Keyword Surfer gives you those numbers instantly.

Plus, it’s 100% free – a great alternative now that some other tools aren’t free.

13. Keywords Everywhere

Best for: Search volume overlays and trendlines across sites

Keywords Everywhere turns your browser into a keyword insight engine.

With an API key (paid credits for volume data), it will display monthly search volume, CPC, and competition metrics beneath Google search boxes and other sites like YouTube, Amazon, and more.

It also adds a trend chart showing interest over time. Many SEO pros love it for the convenience of not having to open a separate tool for basic keyword metrics. If you need more than what free extensions offer – for $10 this get you a huge number of credits that make this effectively freemium.

It’s especially useful if you’re vetting keywords on Google Trends or Google Search Console; Keywords Everywhere will augment those pages with volume data, saving you copy-paste steps.

Just beware it can clutter the SERP with info – but you can toggle it on/off easily.

14. SEOquake

Best for: On-page authority metrics and SERP overlay for competitive analysis

A long-standing favorite, SEOquake provides a toolbar with tons of SEO metrics at a glance.

On any webpage, you can get an “SEO snapshot” including the page’s title, description, word count, internal vs external links, and even a keyword density analysis.

But where it shines is in the SERP: SEOquake can overlay each Google result with metrics like Alexa rank, SEMrush rank, or number of indexed pages. It also has a SERP export feature to download results.

How to use it: Turn it on when you want a quick competitive landscape view.

For example, you search your target keyword and see each result’s domain authority proxies or backlink counts right next to it. This helps evaluate how tough the competition is without manually checking each site.

It’s a versatile Chrome SEO plugin that combines on-page and off-page insights in one package.

15. Glimpse

Best for: Google Trends power-up for instant topic validation

Glimpse supercharges Google Trends by adding something it lacks: actual numbers. Normally, Trends shows relative interest over time with no clear volume axis.

Glimpse changes that by injecting an estimated search volume scale onto the Trends charts. It updates daily and lets you see new trending queries with far more context.

In practice, this means if you spot a rising topic on Google Trends, you can gauge its significance (e.g., “is this in the 1K searches range or 100K?”).

It’s especially useful for Content marketers and SEOs validating topics – you get the trending trajectory plus volume, all in one view. Glimpse often has a free tier (10 searches per month) which is enough for occasional use. For trend-hunters, it’s a gem for staying ahead of the curve.

What are the best Chrome extensions for Local SEO and location testing

These Chrome extensions help you simulate searches from different locations and glean insights about Google Business Profiles – without having to hop on a plane!

16. SEO Search Simulator by Nightwatch

Best for: Simulate Google searches from different locations

If you’ve ever wanted to see un-personalized, local-specific Google results, SEO Search Simulator is the answer. This extension lets you choose a country, city, or even a specific Google domain and then enter a search query.

It shows you the Google SERP as if you were in that location (and with a fresh, logged-out context). This is incredibly useful for checking how your site ranks in different regions or for international SEO audits.

It’s also a safe way to simulate search results without affecting your personalized results or analytics.

Use it to verify your Google My Business (Google Business Profile) rankings in various cities, see competitors in those locales, or just emulate search engine results pages for a country you’re not physically in.

17. GMB Everywhere

Best for: Google Business Profile data for local SEO decisions

GMB Everywhere (short for Google My Business Everywhere) is a nifty extension for local SEOs.

When viewing a Google Business Profile (in Google Search or Maps), it adds extra info and quick-links.

For example, it can show you categories the business is using, the latest reviews, Google Post statistics, and more. It basically layers auditing tools onto the GMB interface.

Why it’s helpful: Suppose you’re researching competitors’ local strategies – GMB Everywhere lets you gather intel like which categories they selected (so you can compare or discover category opportunities) and see their review counts/trends without manual digging.

It also provides direct links to various Google reports for that listing (audit shortcuts). It comes with free and paid versions, where the paid unlocks more in-depth audit data. If local pack rankings matter o you, this SEO Chrome extension gives you an upper hand in fine-tuning your GMB presence.

18. MST SERP Counter

Best for: Number the search results for faster rank tracking

Ever notice how searching a keyword doesn’t show the position numbers of organic results? MST SERP Counter simply adds a numbered index next to each organic listing in Google.

So the first result gets a “1. “, second gets “2. “, and so on. It sounds basic, but it’s wonderfully useful when you’re scanning the SERP or taking screenshots for reports.

For example: if you want to quickly find, say, what the #7 result is, you don’t have to count down the list – the extension labels it for you.

Additionally, with features like people-also-ask boxes and ads, the numbering helps distinguish true organic positions.

For rank tracking or auditing how far down your result appears (especially if there are featured snippets occupying slot #0), this visual aid is a time-saver. No more miscounting or manually annotating screenshots – MST SERP Counter does it automatically.

What are the best Chrome extensions for tech stack detection and market context?

Knowing a website’s tech stack can inform your SEO strategy (and envy, if they have a fancy setup!). These extensions reveal what’s under the hood of any site – from CMS to analytics – and even give traffic estimates to size up the competition.

19. Wappalyzer

Best for: Identify CMS, frameworks, analytics tags, and more

Curious what CMS a competitor uses or if they’re running certain analytics or marketing scripts? Wappalyzer has you covered.

With a click, it displays all the technologies detected on the site: the content management system (WordPress, Shopify, Drupal, etc.), JavaScript frameworks (React, Angular), analytics tools (Google Analytics, Facebook Pixel), CDNs, you name it.

Why SEOs care: The tech stack can hint at site capabilities or limitations.

For example, if you see a site uses Cloudflare, you might check for CDN caching. Or if they run WordPress with Yoast, you know where to look for certain SEO settings.

It’s also great for prospecting – if you’re an agency pitching web development or SEO services, knowing a site’s platform is step one. Wappalyzer satisfies that curiosity instantly and helps you approach each site with context.

20. SimilarWeb

Best for: website traffic and engagement at a glance

For a quick competitor intel briefing, SimilarWeb’s Chrome extension is quite handy.

When on a site, click the extension and it will show estimated monthly traffic, average visit duration, pages per visit, and bounce rate, along with the site’s top traffic sources (e.g., what % is from search vs social) and geolocation of visitors.

It basically miniaturizes the data from similarweb.com into the plugin.

Caution: The data is estimates and can be very rough for smaller sites, so take it with a grain of salt. However, as a relative gauge (e.g., Site A has more traffic than Site B) it’s useful.

You can use it to demonstrate the impact of SEO (if you see a high percentage of traffic from search) or identify competitors’ strong channels. It’s a convenient way to get a pulse on a website’s popularity and audience behavior without logging into analytics – great for competitive research and client pitches.

21. Tag Assistant

Best for: Debug GA/GTM/Ads tags and Consent Mode

Google’s Tag Assistant extension helps ensure your tracking tags are firing correctly.

When you activate it and reload a page, it will report which Google tags it finds (Analytics, Google Tag Manager, Ads conversion tracking, etc.) and whether they loaded successfully. If there are errors (like duplicate GA tags, or a Tag Manager container that didn’t fire), Tag Assistant will flag them.

Why SEOs should care: Analytics data is the bedrock of measuring SEO success. A broken or duplicated Google Analytics snippet can wreak havoc on your data (e.g., self-referrals, inaccurate metrics).

Tag Assistant lets you troubleshoot analytics issues on the spot. It’s also very handy for checking if Consent Management is working (in cases where cookies should be blocked until consent).

In short, this extension makes sure your Chrome browser can tell you, “Yes, your tracking is working (or not working) as expected,” so you can fix any measurement blind spots.

What are the SEO Chrome extensions for structured data acceleration?

Implementing structured data can be tedious if you’re not familiar with JSON-LD. These extensions simplify schema markup generation and verification, so you can enrich your pages with confidence.

22. Schema Builder

Best for: Generate, edit, and validate structured data (JSON-LD)

No need to hand-code JSON-LD from scratch – Schema Builder provides a user-friendly form to create common schema types (FAQ, HowTo, Product, etc.).

You fill in fields (like name, image, price), and it outputs a ready-to-go JSON-LD snippet that you can add to your site. Some Schema Builder tools also let you edit existing schema on a page and test it.

Perfect for: When you want to add structured data but aren’t a coding whiz.

For instance, an e-commerce SEO can quickly generate Product markup by plugging in product details, then copy-paste the JSON into the site.

According to experts, Schema Builder is especially great for e-commerce scenarios, turning schema markup into actionable seo insights without code. Always double-check with Google’s Rich Results Test – but Schema Builder often gets you 90% of the way there with far less effort.

Conclusion
