Can't justify a paid tool right now? Good news: you can do real SEO work without spending a penny. Google gives away tools that many professionals use daily. Here's what they are, what they do well, where they fall short, and how to use them properly.
✓ All tools on this page are free to use
The non-negotiables
These are free tools that every site owner should have set up before even thinking about a paid subscription. If you haven't done this yet, do it today.
Google Search Console
search.google.com/search-console, Free, always
The only tool that shows you exactly how Google sees your site. Real impression and click data, the actual keywords driving traffic, pages Google can't index, Core Web Vitals issues, manual penalty alerts. No third-party tool can replicate this because it comes directly from Google.
100% Free
How to actually use it
Performance report → Queries tab: Sort by Impressions descending. Find pages with high impressions but low click-through rate (under 3%) — those title tags need rewriting.
Coverage report: Any pages with errors need fixing before anything else. Crawl errors mean Google isn't indexing your content.
Performance → Pages tab: Find your top 10 pages by clicks. These are your earners — they deserve the most attention and internal links.
Enhancements → Core Web Vitals: Any pages marked “Poor” are being actively held back. Fix Largest Contentful Paint first.
Links report: See what sites are linking to you and which anchor text they use. Basic but real.
What it does better than paid tools
Actual click and impression data — Semrush estimates, this is real
Index coverage — know exactly what Google can see
Manual action alerts — nothing else tells you this
Core Web Vitals from real Chrome users
Zero cost, no data limits on your own site
What paid tools do that GSC can't
Competitor keyword data — GSC only shows your own site
Keyword difficulty scores
Backlink prospecting and competitor link data
Keyword ideas beyond what you already rank for
Historical data beyond 16 months
Google Analytics 4
analytics.google.com, Free
Tells you what happens after people arrive from search. Which pages they read, how long they stay, whether they convert, where they drop off. Connect it to Search Console and you get one view from keyword to outcome. Essential for understanding which SEO wins are actually moving the needle.
100% Free
How to actually use it
Link GA4 to Search Console: In GA4 → Admin → Search Console Links. Now you can see queries alongside engagement metrics.
Reports → Acquisition → Traffic acquisition: Filter by Organic Search. Which landing pages are getting traffic? Which ones have high bounce rates?
Engagement → Pages and screens: Sort by Average engagement time. Low engagement on a high-traffic page is a content quality signal.
Conversions: Set up at least one goal (email sign-up, contact form, purchase). Without this, you're optimising for traffic without knowing if it pays.
What it does well
Real user behaviour data — not estimates
Conversion tracking — ties SEO to revenue
Audience insights unavailable in GSC
Free, no data caps for most sites
Limitations
GA4 interface is genuinely difficult for beginners
No keyword research or rank tracking
Data sampling on large sites can skew reports
Setup requires correct event configuration
Free keyword research tools
Keyword research is where most free tools fall short. These are the legitimate free options — honest about what they can and can't do.
Google Keyword Planner
ads.google.com/aw/keywordplanner, Free with a Google Ads account
Google's own keyword research tool, built for advertisers but genuinely useful for SEO. Shows real search volume ranges, related keyword ideas, and seasonal trends directly from Google's data. The catch: you need a Google Ads account (free to create, no spend required). Without active ad spend, volume shows as ranges rather than exact numbers.
Free (account needed)
How to get the most out of it
Create a Google Ads account but don't add payment: Skip the campaign setup — click “Switch to Expert Mode” → “Create an account without a campaign.” You get Keyword Planner access without spending anything.
Discover new keywords: Enter 3–5 seed keywords related to your topic. Filter results by Average Monthly Searches and Competition (Low/Medium/High).
Trick for exact volumes: Run a £1 Google Ads campaign briefly to unlock exact search numbers. Pause it immediately. Your data stays accurate. Cost: pennies.
Check seasonality: Click any keyword to see the monthly search trend chart. Useful for planning content around seasonal peaks.
Download to CSV: Export everything — sort in a spreadsheet by low competition + decent volume. That's your free keyword research workflow.
What it does well
Data comes directly from Google — as accurate as it gets
Unlimited keyword lookups
Seasonal trend data for every keyword
Groups keywords by theme automatically
Completely free with no paid subscription
Where paid tools beat it
Volume shown as ranges (100–1K) without active ad spend
No keyword difficulty score — can't tell how hard it is to rank
No competitor keyword data
No rank tracking
Skewed toward commercial/transactional intent
Google Trends
trends.google.com, Free, no account needed
Shows the relative search interest of any keyword over time and by geography. Doesn't give absolute search volumes — it's an index from 0 to 100. Genuinely useful for validating whether a keyword is growing or dying, comparing two topics, and identifying seasonal patterns. Often overlooked, frequently useful.
100% Free
Practical uses
Validate before you write: Search your target keyword. Is the trend flat, rising, or declining? Don't invest heavily in a topic that's been dropping for 3 years.
Compare topics: Enter two competing keywords. Trends shows relative interest — useful for choosing which angle to lead with.
Find related rising topics: Scroll to “Related queries” → switch to “Rising.” These are topics with breakout growth — often low-competition.
Plan seasonal content: Check if your topic spikes in certain months. Write and publish 6–8 weeks before the seasonal peak so Google has time to index it.
Genuinely good for
Trend validation before committing to content
Seasonal planning — more accurate than any paid tool
Spotting rising topics before competitors
Geographic breakdown of interest
Not useful for
Absolute search volumes
Keyword difficulty
Long-tail keyword discovery
Competitor research
Google Autocomplete & People Also Ask
google.com, Free, no account
Underrated. Google's autocomplete suggestions and “People Also Ask” boxes are real keyword data — they reflect what people are actually typing and what Google thinks is related. Not volume data, but excellent for understanding intent and finding long-tail angles that keyword tools miss.
100% Free
How to use it systematically
Autocomplete mining: Type your seed keyword followed by each letter of the alphabet (e.g. “SEO tool a”, “SEO tool b”...). Screenshot or copy every suggestion. These are all real searches.
People Also Ask: Click one PAA question to expand it — more related questions appear. Keep clicking. You can generate 20–30 related FAQ ideas in 5 minutes.
Related Searches: Scroll to the bottom of any results page. 8 related searches, all real. One of those is often a better keyword than your original.
Use a browser in Incognito mode to remove personalisation from your results. More accurate for keyword research.
Free technical SEO tools
Technical SEO problems can hold back a site regardless of how good the content is. These tools find the most common issues at no cost.
Screaming Frog SEO Spider (free tier)
screamingfrog.co.uk/seo-spider, Free up to 500 URLs
The paid version is the industry standard for technical SEO. The free version crawls up to 500 URLs and is not a crippled demo — it finds broken links, duplicate title tags, missing meta descriptions, redirect chains, and canonical issues. For any site under 500 pages, the free version does everything the paid version does except Google Analytics integration and JavaScript rendering.
Free up to 500 URLs
First crawl workflow
Enter your domain and hit Start. Let it run.
Response Codes tab → filter 4xx: These are broken pages. Fix or redirect them.
Page Titles tab: Filter for “Missing” and “Duplicate.” Both hurt rankings.
Meta Description tab: Same — filter missing and duplicate.
Directives tab → Canonicals: Look for canonical tags pointing to wrong URLs.
Redirect Chains report: Multiple redirects in a row waste crawl budget and dilute link equity.
Free version covers
Full technical audit for sites under 500 pages
Broken links, missing tags, redirects, canonicals
Everything most small sites actually need
Need the paid version (£259/yr) for
Sites over 500 pages
Google Analytics / Search Console integration
JavaScript rendering (SPAs)
Scheduled automated crawls
Google PageSpeed Insights
pagespeed.web.dev, Free
Tests any URL for Core Web Vitals and performance issues. Uses both lab data (simulated) and real-world data from Chrome users. Gives a scored report with specific recommendations. Page speed is a confirmed ranking factor — this tells you exactly what to fix and in what order.
100% Free
How to read the results
Mobile score matters more than desktop for most sites. Google uses mobile-first indexing.
Largest Contentful Paint (LCP): Should be under 2.5 seconds. Usually fixed by optimising your hero image or largest above-fold element.
Cumulative Layout Shift (CLS): Elements shouldn't move around as the page loads. Common cause: images without defined height/width attributes.
Opportunities section: Listed in order of impact. Work through these top-down — they're prioritised by how much time each fix saves.
Google Rich Results Test
search.google.com/test/rich-results, Free
Tests whether your schema markup is valid and eligible for rich results in Google search. If you have FAQ schema, Product schema, Review schema, or How-To markup, this tells you whether it's going to work or whether there's an error preventing it from showing. Takes 10 seconds per URL.
100% Free
When to use it
After adding any structured data to a page — validate before publishing.
If your rich results disappear from Google — check here first for errors.
To test competitor pages — enter their URL to see what schema they use.
Free competitive research tools
Understanding what competitors are doing is harder without a paid tool, but not impossible.
Google Ads Transparency Center
adstransparency.google.com, Free, no account
Google's public database of every active search and display ad. Search any brand or domain and see every ad they're currently running, the ad copy, which regions they target, and how long the ads have been live. Primarily a paid search tool, but the ad copy tells you a lot about what messaging a competitor is testing and what they believe converts.
100% Free
SEO uses for an ads transparency tool
Steal title tag ideas: Ads that have run for months are proven copy. If a competitor has been running the same headline for 6 months, it's working. Adapt that angle for your title tags.
Understand their value proposition: What do they lead with? Price? Speed? Trust? This tells you what the market responds to.
Find which products they're pushing: Active ads reveal which parts of their business they're actively investing in — which means those are competitive areas.
Track changes over time: New ads appearing on keywords you target means a competitor is moving into your space.
Useful for
Real ad copy from real campaigns — not estimated
Understanding competitor messaging and positioning
Title tag and meta description inspiration
No account or login required
Not useful for
Organic keyword rankings — only shows paid ads
Traffic estimates
Backlink data
Competitors who don't run Google Ads
Ahrefs Webmaster Tools (AWT)
ahrefs.com/webmaster-tools, Free for verified site owners
Free access to Ahrefs' backlink and crawl data for sites you own. Verify ownership via DNS or HTML tag and you get: all backlinks to your site, which pages have the most link equity, crawl errors Ahrefs found, and basic keyword rankings. The data is from Ahrefs' paid database — you're getting real professional-grade data for free, limited to your own site only.
Free (own sites only)
What to check first
Backlinks report: See every site linking to you. Check for toxic-looking links you'd want to disavow, and identify your strongest backlinks for outreach follow-up.
Best by links: Which pages have the most backlinks? Those pages should link internally to pages you want to rank.
Site Audit: AWT runs a crawl and flags technical issues — similar to Screaming Frog free tier but cloud-based.
Organic keywords: Limited in free version, but shows your ranking keywords with real Ahrefs data.
Bing Webmaster Tools
bing.com/webmasters, Free
Bing's equivalent of Google Search Console, and significantly underused. Bing Webmaster Tools has a keyword research tool (free, with volume data), a backlink analysis tool, and crawl data. In 2026, Bing powers Copilot and several AI search experiences — if you care about AI search visibility, Bing is more relevant than it was two years ago.
100% Free
Features worth using
Keyword Research tool: Free, shows actual search volume (not ranges like GKP without spend). Import your site and it suggests keywords based on your content.
Backlinks report: Shows links Bing has crawled. Different from Google's link graph — sometimes surfaces links GSC misses.
SEO Reports: Free site audit focused on Bing's crawl — usually surfaces the same issues as Google, so it's a useful second opinion.
Moz Link Explorer (free tier)
moz.com/link-explorer, 10 free queries/month
10 free backlink lookups per month with no account required (more with a free account). Enter any domain or URL and see their Domain Authority, top linking domains, and a sample of backlinks. Not a full picture, but enough for a quick competitive check on link building targets.
10 free/month
Best use of your 10 free lookups
Check DA on sites before pitching guest posts — is the link actually worth getting?
Look at competitor backlink profiles to identify which sites link to them that might link to you.
Verify new links you've built are being indexed correctly.
Ubersuggest (free tier)
neilpatel.com/ubersuggest, 3 free searches/day
3 keyword or domain lookups per day without signing up. Gives keyword volume, difficulty score, and a small sample of ranking pages. Limited, but useful for quick spot checks. Creating a free account increases the limit slightly. Note the known accuracy issues on low-volume keywords — verify important data in GSC.
3 free/day
Make the most of 3 daily lookups
Use on your highest-priority keywords only — don't waste lookups on terms you already know.
Look at the “Content Ideas” tab for a target keyword — shows real pages ranking and their estimated traffic.
Domain overview on a competitor — see their estimated top keywords.

The free SEO stack — set this up before spending a penny
In order. Each step builds on the last.
1
Google Search Console + Google Analytics 4 — Non-negotiable. Verify your site, connect both. This is the data foundation everything else depends on. Free, takes 30 minutes.
2
Ahrefs Webmaster Tools — Verify your site for free backlink and crawl data from Ahrefs' database. Takes 10 minutes.
3
Bing Webmaster Tools — Free keyword research with actual volume data. Import your sitemap. Often overlooked but the keyword tool alone is worth it.
4
Screaming Frog free — Crawl your site. Fix every broken link, duplicate title, and redirect chain. Do this once a quarter.
5
Google Keyword Planner + Trends — For keyword research, use GKP for volume ranges and Trends for direction. Supplement with Autocomplete and PAA for long-tail ideas.
6
PageSpeed Insights on your top 5 pages — Fix LCP and CLS issues. These have a direct impact on rankings and user experience.
When free tools aren't enough
Free tools cover a lot of ground. But there are specific points where the gap becomes a real business problem.
You need competitor keyword data. Free tools only show your own site. The moment you need to know what keywords a competitor ranks for — to find content gaps, analyse their strategy, or understand why they outrank you — you need a paid tool. There is no free alternative that does this properly.
You need daily rank tracking. GSC shows impressions and clicks but not daily position data in a format you can monitor and report on. Once you're actively optimising and need to see whether changes are working within days, Wincher ($49/mo) or SE Ranking ($65/mo) are the cheapest options.
Your site is over 500 pages. Screaming Frog's free crawl limit hits and stops. The paid licence at £259/year is around £22/month — cheaper than any all-in-one platform and does the technical work better than most of them.
Ready for a paid tool?
SE Ranking at $65/month covers everything the free stack can't — daily rankings, competitor keywords, backlink data, site audit with no URL limit, and AI content tools. 14-day free trial, no card required.
Yes, with limits. You can audit your own site, track your actual performance in GSC, research keywords using GKP and Trends, fix technical issues with Screaming Frog free, and analyse your own backlinks via Ahrefs Webmaster Tools. What you can't do for free is competitor keyword research or reliable daily rank tracking — those require a paid tool.
Yes, though with one caveat. Without active ad spend, volumes show as ranges (100–1K) rather than exact numbers. For most keyword research decisions — is this worth targeting, is it high or low volume — the range is enough. The trick of running a tiny campaign briefly to unlock exact numbers works if you need precision.
GSC shows how your site performs in Google search — impressions, clicks, rankings, crawl issues. GA4 shows what happens after people arrive — behaviour, time on site, conversions. They're complementary, not alternatives. You need both. Connect them in GA4 settings to get a combined view.
Yes — Ahrefs has confirmed it's permanently free for verified site owners. You verify ownership via DNS record or HTML tag (same as GSC). You get real Ahrefs backlink data and crawl data for your own site, with no trial period or credit card required. The limitation is it only covers sites you verify — no competitor data.
Because ads that have run for months represent tested, proven copy. Competitors investing in Google Ads are showing you what messaging they've found converts. Their best-performing ad headlines are often better title tag inspiration than any keyword tool — they've been A/B tested against real users. It's free competitive intelligence.
Bing Webmaster Tools, consistently. It has a free keyword research tool with actual volume data (not ranges like GKP), a backlink analysis tool, and crawl data. Most SEOs never set it up. Takes 20 minutes. Given Bing now powers several AI search experiences including Copilot, ignoring it is increasingly expensive.
