Chrome SEO extensions are the fastest way to check the title, meta description, headings, redirects, or link structure without digging into the page source. In this roundup you’ll find seven extensions used by both SEO consultants and webmasters: three for on-page analysis, one for full audits with link metrics, two for tracking redirects and HTTP headers, one for simulating search results from any location, and one for keyword research. All of them run in Chrome.

On-page analysis extensions
Three extensions that essentially do the same thing – they show metadata, headings, canonical, robots, schema markup, and links on the open page. They differ in details and in what they’re best optimized for.
Detailed SEO Extension
Built by Glen Allsopp from Detailed.com and acquired by Ahrefs in 2024 – they’re the publisher in the Chrome Web Store today.
Click the “D” icon next to the address bar and you get a panel with tabs: Overview (title, meta description, canonical, meta robots, word count, indexability), Headings (H1-H6 with indentation showing hierarchy and font size growing with heading rank), Links (internal, external, nofollow, anchor texts), Images (alt texts), Schema (schema.org, Open Graph, Twitter, hreflang), and Social (social media share preview). Every list of links and images can be exported to CSV.
The Advanced tab has two interesting things most competitors don’t:
- User-Agent switcher to Googlebot (and a few other bots) without touching DevTools,
- “People Also Asked” extractor from Google results, optionally multi-level.
Right-click also opens shortcuts to view the current page in Ahrefs, Moz, SEMrush, Wayback Machine, and SimilarWeb. This is the fastest way to check whether the competition has backlinks once you’ve diagnosed on-page.
💡 Tip: Detailed SEO Extension only covers the current page – it doesn’t crawl the whole site. For a full crawl, use Screaming Frog or Sitebulb.
All in One SEO Analyzer by AIOSEO
An extension from Semper Plugins – the same company behind the AIOSEO plugin for WordPress.
It does what the name suggests: an SEO score for the page, analysis of meta tags, headings, keyword density, image alt attributes, structured data, plus simple internal and external link diagnostics. The score is helpful if you work with clients who like seeing “85/100” rather than a raw “issues” list – but treat it as guidance, because it’s AIOSEO’s internal algorithm, not any official standard.
⚠️ Heads up: the latest update in the Chrome Web Store is from October 2024 (version 1.0.2). Functionally the extension still works, but if you want a regularly maintained tool, Detailed or SEO Pro will be the better pick.
SEO Pro Extension
Publisher: marketingsyrup.com, an extension focused on speed for everyday checks. The interface is less elaborate than Detailed, but it shows a few things that one doesn’t surface as directly.
Where SEO Pro shines:
- Core Web Vitals from field data (LCP, INP, CLS) – pulled from CrUX, so you see real user experience instead of a synthetic test result.
- One-click export of all the page’s text content – useful when you want to feed a competitor’s text into a semantic analysis.
- Status codes and redirect chains visible right in the main view.
- CSV export of headings, links, and images – including nofollow attributes and anchor texts.
- Highlights nofollow links on the open page.
The heading hierarchy view shows the H1 count (and warns when there’s more than one) plus the H2-H6 layout, which makes it easier to spot gaps in your content structure.
Extension for full audits – Ahrefs SEO Toolbar
The Ahrefs toolbar pulls together three worlds: page tech, link analysis, and keyword research. It’s available in 15 languages, including Polish – one of the few extensions in this roundup with a Polish localization.
The free version gets you: title and metadata preview, HTTP header and response code checks, redirect tracking, link highlighting on the page with filtering (internal/external, dofollow/nofollow), broken link detection, CSV export of links, User-Agent switching to Googlebot, saving URLs from open tabs or SERPs, and switching Google’s region, language, and domain without a VPN.
Once you log into a paid Ahrefs account, you get the metrics that are the actual point of this toolbar: Domain Rating, URL Rating, estimated organic traffic, keyword count, referring domains – displayed right next to every SERP result and on every page you open. This is the only moment you see a competitor’s “link potential” without clicking through to a separate tool.
💡 Tip: if you already pay for Ahrefs, this toolbar saves you dozens of clicks a day. If you don’t pay – it’s still one of the better free extensions for basic technical checks available in Polish.
Extensions for redirects and HTTP header analysis
Two extensions that solve the same problem – “why isn’t this URL the URL it seems to be” – but at different levels of detail.
Redirect Path
An extension from UK agency Ayima. It runs quietly in the background: when you open any page, the icon next to the address bar changes color and shows the number of redirect steps the URL went through.
Click the icon and you’ll see the full list of steps with response codes: 301, 302, 307, 404, 500, plus client-side redirects (Meta refresh, JavaScript). On top of that, it shows HTTP headers (server type, cache headers, X-Robots-Tag) and the server’s IP address.
What Redirect Path doesn’t show: any SEO assessment of the redirect or link metrics. This is a diagnostic tool, not an audit tool.
✅ Worth checking: when you migrate a domain or restructure URLs, Redirect Path helps you verify whether old addresses actually point to new ones with a single 301 – rather than a chain like 301 → 301 → 200, which leaks authority and frustrates crawlers.
Link Redirect Trace
An extension from LinkResearchTools (LRT) – a more elaborate cousin of Redirect Path.
At every step of the redirect chain it shows:
- whether robots.txt blocks crawlers from accessing that URL (it also checks the
X-Robots-Tagheader), - which URL drops cookies,
- LRT Power and LRT Trust for the address (proprietary LinkResearchTools metrics),
noindexandnofollowtags at every stage,- bot-specific blocking – cases where the page behaves differently for Googlebot than for the browser.
| Feature | Redirect Path | Link Redirect Trace |
|---|---|---|
| Redirect chain | yes | yes |
| HTTP codes (301/302/404/500) | yes | yes |
| Meta refresh and JS redirects | yes | yes |
| Server HTTP headers | yes | yes |
| robots.txt check at every step | no | yes |
| noindex/nofollow tags per step | no | yes |
| Link metrics (LRT Power/Trust) | no | yes |
| Account required | no | no |
| Best for | quick migration diagnostics | broader link audits |
SERP simulation extension – SEO Search Simulator by Nightwatch
The Google results you see in your own browser are personalized: based on history, location, and previous clicks. That means your “position 3 for ‘pizza near me’” might be someone else’s “position 11”. The SEO Search Simulator from Nightwatch.io solves this by running neutral queries from a chosen location.
It’s straightforward: type your query, pick a country and city, enter the domain you want to check, and the extension shows where that domain ranks in roughly the first 100 results. The result is “clean” – no influence from your history and no geo-bias from where you actually sit.
⚠️ Heads up: with heavy use, Google enforces rate limits and can throw captchas at you. The extension makes sense for quick, ad-hoc checks – not regular rank tracking, which is what Nightwatch’s paid app is for.
Keyword research extension – Keywords Everywhere
In the free version, Keywords Everywhere gives you: estimated traffic and the top 10,000 keywords for any domain or URL, Moz metrics (Domain Authority, Spam Score, referring domains, backlinks), SEO Difficulty and On-Page/Off-Page Difficulty indicators, widgets with related keywords, People Also Search For and long-tail phrases, keyword analysis for any page’s content, visualization of Google Search Console reports, an Instagram hashtag generator, metrics for YouTube, Pinterest, and Twitter, and – interestingly – fanout queries, the hidden queries ChatGPT and Gemini use to generate answers.
The paid version adds what most people actually come to Keywords Everywhere for: exact monthly search volumes, CPC, competition, and 12-month trend – displayed right under the search bar in Google, YouTube, Amazon, eBay, Etsy, Bing, DuckDuckGo, Google Search Console, Keyword Planner, and Trends. Plus historical data going back to 2004, custom keyword list imports, and competitor gap analysis.
Pricing comes in two flavors: a subscription, or pay-as-you-go – you buy a credits pack (one credit = one volume lookup). The pay-as-you-go path works out cheaper than monthly Ahrefs or Semrush subscriptions for occasional users, but the data mainly comes from Google Keyword Planner and is less granular than what the “big” tools offer.
💡 Tip for the Polish market: Keywords Everywhere also handles Polish queries and shows volumes for Poland, but if Polish is your main working language, pair it with DataForSEO or Senuto for full research – both have far deeper data for the Polish market.
How to pick the right extensions for your workflow
The simplest heuristic: one on-page analyzer, one redirect tool, and one for keywords covers 90% of your daily work. Which specific extension you pick depends on what you do most often.
