In short.

Free SEO tools will not rank your site, but used well they show you where you are losing enquiries. PromotEdge's SEO team tests tools like these and uses them every day to find weak points.

We then check the result against enquiries. SEO (search engine optimisation) tools keep you updated with data about your website. They make it easier to study your competitors, find your weak points and spot areas to improve.

This post lists SEO tools and browser extensions that are fast and easy to use. We checked each one on its own site in October 2026. Some have a part that costs nothing and a part that is paid, and we say which.

We have not picked these at random. Our SEO team has tried them. Plans and limits change often, so check each tool's current terms before you install it.

We have grouped the tools by what they do. The last group has our 2 favourite all-in-one SEO tools, which we cannot do without.

Here is the list, group by group.

Free SEO tools and extensions by use

a) On-page SEO

1. SEOInfo: It alerts you to SEO-related technical errors as you move through the pages of a website. It shows errors such as invalid canonical links, AMP pages and hreflang tags. It shows pages or resources blocked by robots.txt. It also shows errors in images, CSS or JavaScript files. It also shows performance data such as page speed and file size, which matter for SEO.

2. SEOquake: A browser toolkit for on-page SEO. Its page says it runs on-page audits, shows internal links, compares URLs in real time and exports the data to a file. The download costs nothing. You can analyse pages right in the Google search results.

3. Beam Us Up: A crawler you download for Windows, Mac or Linux. Its own page says it costs nothing and has no limits. It checks broken links, redirects, duplicate content, page titles, meta descriptions, headings, canonical tags and XML sitemaps. It can also show Google PageSpeed scores through Google's API.

b) Keyword research

4. Keywords Everywhere: Type a keyword in Google, and this extension shows related and long-tail keyword ideas on the page. It costs nothing to install, and 18 of its features work without a sign-up. Search volume, CPC (cost per click) and competition data run on credits, so that part is paid.

5. Keyword.io: Its own page says it costs nothing and you can search without an account. You need an account only to save keywords into lists. It makes long-tail keyword ideas from autocomplete suggestions on sites such as Google, YouTube, Bing and Amazon. Amazon and some other sources are rate limited, so use Google, YouTube or Bing for unlimited searches.

c) Rank checking

6. SERPTrends SEO Extension: A Chrome extension that shows ranking changes on the Google results page. Its Chrome Web Store listing says it shows which sites are moving up or down. The listing shows an update in June 2025. Use it to spot-check competitors on your most important keywords.

7. CanIRank: SEO software for small businesses and startups. It covers keyword research and keyword difficulty. It checks competitors, tracks ranks and sends weekly progress reports. It also gives task-based advice, and its page says it uses AI to do that. It offers a trial, and plans are paid after that.

8. Fatrank: A Chrome extension that checks where the site you are viewing ranks for a keyword on Google. Its listing says it costs nothing. It checks up to position 100 and shows 'Not found' beyond that. It uses your Google location settings, so set your location to your country for country-level results. Many checks in a short time can make Google block results for a while. You can export the session history as a CSV file.

d) Technical SEO

9. PageSpeed Insights: Many searches are done from smartphones, so you should check your website's loading speed. If a site takes too long to load, visitors leave. PageSpeed Insights tests mobile and desktop. It shows field data (real visits over the last 28 days) and lab data (a test run by Google's Lighthouse tool). The score runs from 0 to 100. A score of 90 and above is good, 50 to 89 needs work and below 50 is poor.

PageSpeed Insights also reports Core Web Vitals. LCP is how fast the main content loads, and 2.5 seconds or less is good. INP is how fast the page responds to a tap or click, and 200 milliseconds or less is good. CLS is how much the layout jumps, and 0.1 or less is good.

10. Redirect Path: It shows all the redirects between the URL you entered and the final URL. It also shows whether they work or are broken. It flags 301, 302, 404 and 500 HTTP status codes. It also flags client-side redirects such as Meta and JavaScript redirects. So you spot issues that might go unnoticed.

Google Search Console is Google's own tool, and it costs nothing. Its Performance report shows how often your site appears in Search, which searches show it and how often people click. Its Indexing tools help you fix indexing problems and ask Google to look at new or updated pages.

e) Link building

11. Hunter: Hunter's no-cost plan includes 50 credits a month. Finding an email address costs 1 credit, and verifying one costs half a credit. You can use it to find email addresses linked to a website.

f) All-in-one

12. SEO Minion: A browser extension from Keywords Everywhere. It works in Chrome, Firefox or Edge. It shows meta tags, headings and canonical settings for a page, and checks broken links. It previews how your title and description may look on Google, and it checks results for different locations. Its page says it is included with paid Keywords Everywhere plans and needs an API key, so check the current terms.

13. MozBar: Our team that provides SEO services in Ranchi uses this tool. MozBar shows Domain Authority and Page Authority. It highlights followed, nofollow, internal and external links, and checks schema markup, hreflang, robots.txt and sitemaps. Its Chrome Web Store listing says guests get on-page elements and link details, a basic Moz account adds Domain Authority and Page Authority, and some features need a Moz Pro subscription. It helps when you research competitors.

SEO audit tool or SEO audit consultant?

An audit tool scans your site and lists errors: broken links, slow pages, missing titles and duplicate content. It is quick and cheap to repeat, so use it for regular checks.

An audit consultant reads those results with your business in mind. They sort the fixes by impact and look at things tools miss, such as whether your pages answer what searchers want, and whether your content is thin, outdated or repeated. A content quality audit asks that last question page by page.

Use a tool for steady checks. Call in a consultant when traffic stalls, or before a redesign. Google's own advice is that a great time to hire an SEO is when you are planning a site redesign, the earlier the better.

AI Overviews and AI Mode in Google do not change these checks. Google says there are no extra requirements to appear in them, and no special files or markup are needed. Your page must be indexed and eligible to show with a snippet. Google counts this traffic in Search Console's Performance report under the Web search type, so you cannot see it on its own. A Pew Research Center study of US adults in March 2025 found that people clicked a regular result link in 8% of visits with an AI summary, against 15% without one.

Wrapping up

If the long list feels like too much, do not worry. PromotEdge offers SEO services in Ranchi that are trackable and measurable.

Some tools promise quick rankings by buying links in bulk or stuffing pages with keywords. Google lists link spam, keyword stuffing and scaled content abuse as spam. Pages that break its policies may rank lower or not appear at all. Use tools to find problems and fix them, not to trick search engines.

We work to improve your website's visibility and traffic.

  • Yes. Hunter's no-cost plan includes 50 credits a month. Finding an email address costs 1 credit, and verifying one costs half a credit. Keep any email short and honest, and say why your page would help the blogger's readers. A tool only finds contacts. The link comes from a page worth linking to.
