The best free SEO tools for a small business are the ones Google and Microsoft give you for your own site: Google Search Console, Bing Webmaster Tools, Google Analytics 4 and Google Business Profile. Add PageSpeed Insights, the Rich Results Test and a free crawler such as Screaming Frog's free version or Ahrefs Webmaster Tools, and you can run most of the SEO a small business needs without paying for a subscription. What costs money is the time and judgement to act on what these tools show you.
I have used every tool below on client and personal sites. This list is about doing the basics properly, not about collecting dashboards.
How I chose these tools
- Genuinely free for a small site. Either fully free or with a free tier that is useful on its own, not a seven-day trial.
- First-party or reliable data. Data from Google or Microsoft about your own site beats third-party estimates for most small businesses.
- Covers a real job. Each tool answers a specific question: is my site indexed, is it fast, what do people search, why are visitors leaving.
- Usable without a developer. An owner or a junior marketer can learn the basics in an afternoon.
Everything below was checked on the vendor's official site as of October 2026. Free tiers change, so check each vendor's page before you plan around a limit.

1. Google Search Console
What it is: Google's free service for monitoring how your site appears in Google Search. It shows which queries you appear for, clicks, impressions, average position, indexing problems and the sites linking to you.
Who it suits: Every business with a website. If you install only one tool, install this.
What it does well: It is the only place you get Google's own data on your search performance. Google announced dedicated generative AI performance reports in June 2026 and says they were rolled out to all websites by 31 August 2026. They show impressions, pages, countries, devices and dates for your URLs appearing in generative AI features such as AI Overviews and AI Mode.
Limits: The AI report shows impressions, not clicks, and it groups AI features together. Query data is sampled and some queries are hidden for privacy.
Tip: Verify the domain property (not just one URL prefix) and submit your XML sitemap on day one. Then check the Pages report monthly for anything "not indexed" that should be.
2. Bing Webmaster Tools
What it is: Microsoft's free equivalent for Bing. You can import sites you have already verified in Google Search Console.
Who it suits: Anyone who cares about AI answers as well as classic search.
What it does well: In February 2026 Microsoft launched AI Performance as a public preview. According to Bing's own announcement, it shows total citations, average cited pages, a sample of grounding queries and page-level citation counts across Microsoft Copilot, AI summaries in Bing and select partner integrations.
Limits: Bing says the metrics show how often you are cited, not your ranking or placement within an answer. It is a preview, so expect changes.
Tip: Use the GSC import to set it up in minutes, then compare the pages Copilot cites with the pages Google shows in AI features.
3. Google Analytics 4
What it is: Google's free analytics product for websites and apps. A paid tier, Analytics 360, exists for larger organisations.
Who it suits: Every business that wants to know whether SEO traffic turns into enquiries.
What it does well: It connects traffic to outcomes: form submissions, calls, WhatsApp clicks, purchases. It also integrates with Search Console and Google Ads.
Limits: The interface takes time to learn, and it only reports what you set up. Without key events configured, it tells you very little.
Tip: Define three to five key events that represent real leads before you look at any traffic report. Tag campaign links consistently with the UTM builder so paid and email traffic don't get muddled with organic. If traffic is healthy but leads are not, read why websites get traffic but no leads.
4. Google Business Profile
What it is: Your free listing on Google Search and Maps. Google states that creating a profile is free.
Who it suits: Clinics, showrooms, restaurants, real estate offices, service-area businesses: anyone who serves a location.
What it does well: You can manage hours, services, products, posts and reviews, and see insights such as the searches, calls and bookings that came through the profile.
Limits: It does nothing for a purely online business, and suspensions can happen if details don't match your real address and signage.
Tip: Choose the most accurate primary category, reply to every review, and keep your name, address and phone exactly the same as on your website. My local SEO checklist covers the rest.
5. PageSpeed Insights
What it is: Google's free speed test. It reports field data from real Chrome users over the previous 28 days and lab data from Lighthouse.
Who it suits: Every site, especially mobile-heavy audiences.
What it does well: It shows your Core Web Vitals (LCP, INP and CLS) and whether a page passes, plus specific suggestions such as oversized images or render-blocking scripts.
Limits: Small sites often lack enough real-user data, so you only get lab results. The lab score swings between runs.
Tip: Test your five most important templates (home, service, product, blog, contact), not just the homepage. Fix what the field data flags first.
6. Rich Results Test
What it is: A free Google tool that checks a public page, or pasted code, for structured data and tells you which rich results Google could generate from it.
Who it suits: Sites using schema for products, FAQs, reviews, events, articles or local business details.
What it does well: It catches broken or missing required fields before you publish.
Limits: Valid markup makes a page eligible; it does not guarantee rich results will show.
Tip: Run it after every theme or plugin update. Those updates quietly break schema more often than people expect.
7. Google Trends
What it is: A free view of search interest over time and by region. Google's help pages explain that the data is relative: each point is scaled from 0 to 100 based on a topic's share of all searches, not an absolute search count.
Who it suits: Seasonal businesses, and anyone choosing between two ways of describing the same thing.
What it does well: Timing content and campaigns, and comparing which phrasing people in a particular state use more.
Limits: No volumes. A score of 100 is peak relative interest, not a number of searches.
Tip: Set the country to India and compare terms side by side, then filter by state if you serve a region.
8. Google Keyword Planner
What it is: A keyword research tool inside Google Ads. Google's help page says you need to complete account setup, including billing information, to access basic features such as keyword ideas.
Who it suits: Businesses that want keyword ideas from Google's own data without a paid SEO suite.
What it does well: Generating related keyword ideas from a seed term or a competitor's URL, with monthly search estimates.
Limits: It is built for advertisers, so figures are estimates and very low-volume keywords may not appear.
Tip: Use it for direction, not precision. Group keywords by intent and map each group to one page.
9. Screaming Frog SEO Spider (free version)
What it is: A desktop crawler that finds broken links, redirects, duplicate titles, missing meta descriptions and similar technical issues. The official site states the free version crawls up to 500 URLs per crawl; the paid licence is listed at £199 per year.
Who it suits: Small sites under 500 URLs, and anyone comfortable with a spreadsheet-style interface.
What it does well: Showing every page's status code, title, H1 and canonical in one view.
Limits: The free version cannot save crawls and some configuration is locked. The interface is technical.
Tip: Crawl, sort by status code, and fix every 404 and redirect chain on internal links first.
10. Ahrefs Webmaster Tools
What it is: Free access to parts of Ahrefs for websites you verify. As of October 2026 the official page lists Site Audit (5,000 crawl credits per project per month), Site Explorer (up to 1,000 backlinks and keywords visible), and Web Analytics (up to 1 million events per project).
Who it suits: Owners who want backlink and keyword data that Search Console doesn't present as clearly.
What it does well: A cloud-based site audit and a readable view of who links to you.
Limits: Works only on sites you own and verify, and the visible data is capped.
Tip: Schedule the audit monthly and only fix issues on pages that matter commercially.
11. Microsoft Clarity
What it is: A behaviour analytics tool that Microsoft describes as "free forever" with no traffic limits. It provides heatmaps and session recordings.
Who it suits: Businesses that rank and get traffic but don't get enough enquiries.
What it does well: Showing where visitors scroll, click and stall. The site also describes AI summaries and an AI visibility feature for bot crawling and citations.
Limits: Recordings capture behaviour, so you must update your privacy policy and mask sensitive fields.
Tip: Watch ten recordings of visitors who reached a service page and left. Patterns appear fast.
How to choose (and what to skip)
- Start with the four foundations: Search Console, Bing Webmaster Tools, GA4 and, if you serve a location, Business Profile. They cost nothing and nothing else replaces them.
- Add one diagnostic tool per problem. Slow site: PageSpeed Insights. Technical errors: Screaming Frog or Ahrefs Webmaster Tools. Poor conversion: Clarity.
- Don't pay until a free tool's limit actually blocks you. If your site has 200 pages, a 500-URL crawl limit is not a limit.
- Set a monthly 60-minute review. Tools only help if someone looks. A fixed review slot beats a stack of unused logins.
- Skip "SEO score" widgets. A single score rarely maps to what drives enquiries.
Where I help: I set up and connect these tools, then turn the data into a short list of actions. That is usually part of an audit or ongoing SEO strategy work.
Frequently asked questions
Can I do SEO with only free tools?
For most small businesses, yes. The free tools from Google and Microsoft show your real search data, and free crawlers cover technical checks. Paid suites mainly add competitor research and larger data limits, which matter more as you scale.
Is Google Search Console enough on its own?
It is the most important tool, but it won't tell you what visitors do after they arrive. Pair it with GA4 for conversions and with a crawler for technical issues.
Do free tools show whether I appear in AI answers?
Partly. As of October 2026, Search Console shows impressions in Google's generative AI features and Bing Webmaster Tools shows Copilot and Bing AI citations. Neither covers every AI assistant, so treat them as a starting point.
Is Keyword Planner really free?
Google's help page says you need to complete Google Ads account setup, including billing details, to use keyword ideas. Check Google's current requirements, and whether running campaigns changes the detail you see, before you rely on it.
How often should I check these tools?
A monthly review is enough for most small businesses, plus a quick check after any site redesign, migration or plugin update. Search Console also emails you when it spots a critical issue.
Next step
If you've set these tools up and aren't sure what the data is telling you, a 30-minute strategy session (₹2,999 + GST) is a simple way to get a second opinion and a short list of priorities. No obligation beyond that call.
