The 11 Best Free SEO Tools in 2026 (No Trials, No Catch)
Genuinely free SEO tools—not trials dressed up as free tiers. What each one covers, where the free limit bites, and how to run a complete SEO workflow at zero cost.
Most "free SEO tools" lists are lead magnets. They pad the count with 7-day trials, freemium tiers that expire the moment you do anything useful, and the vendor's own product at number one.
This one has a rule: if it stops working after a trial period, it isn't on the list. Everything below is free indefinitely, with the real limits stated.
Full disclosure: we build Sightivo, which appears at number three — a free checker that needs no account at all, plus a free plan. The other ten are free from someone else.
The Best Free SEO Tools at a Glance
| Tool | Job | Real free limit |
|---|---|---|
| Google Search Console | Your search performance and links | None — fully free |
| Bing Webmaster Tools | Second index + competitor peek | None — fully free |
| Sightivo | Whether ChatGPT names you + where to get mentioned | Checker: no signup · Plan: 10 opportunities/wk |
| Ahrefs Free | Backlinks and audit for your own site | Verified sites only |
| Google Analytics | What visitors do after they arrive | None for most sites |
| Screaming Frog | Technical crawl | 500 URLs per crawl |
| Google Trends | Demand and seasonality | None |
| PageSpeed Insights | Core Web Vitals | None |
| Moz free tools | DA checks and spot research | Limited queries/day |
| AnswerThePublic | Question research | A few searches/day |
| Google Business Profile | Local visibility | None |
What "Free" Really Buys You in 2026
Complete measurement. Search Console, Bing Webmaster Tools and Analytics together tell you what you rank for, what gets clicked, what links you have and what people do next. Nothing paid improves on this for your own site.
Adequate technical auditing. Screaming Frog's 500-URL limit covers most sites entirely.
Enough research to start. Free tiers of keyword tools are capped but workable for a small target list.
A shortlist of places to get mentioned. Newer, and the gap that used to require paid tools.
What free still won't do: competitor backlink analysis at scale, reliable contact data at volume, automated follow-ups, or ongoing alerts across a large link profile.
The 11 Best Free SEO Tools
1. Google Search Console
Not just the best free SEO tool — the best SEO tool, for your own site, at any price.
What you get: Every query you appear for, impressions and clicks, average position, indexing status, the links Google has recorded, and Core Web Vitals. Where it stops: Sampled link data, no competitor view, 16 months of history, no alerts on lost links. Pro move: Filter for queries ranking positions 8–20 with decent impressions. Those are pages one small improvement away from real traffic.
2. Bing Webmaster Tools
What you get: Bing's index of your links, keyword research, site audit — and a competitor comparison view Search Console has no equivalent of. Where it stops: Bing's view of the web, and a smaller traffic share for most sites. Why it matters more now: Bing's index feeds Microsoft Copilot, so this is partly an AI visibility tool.
Our tool
3. Sightivo (free checker + free plan)
Ours, and included because it does a job the rest of this list doesn't: telling you where to go get mentioned. Everything else here reports on what already exists.
Start with the free checker — no account, nothing to install. The AI Visibility Checker takes your domain, works out the buying questions people in your category actually ask, puts them to ChatGPT with live web search, and tells you how many of those answers named you — and which competitors took the slots you missed. First check needs no email. It is a spot check rather than a measurement (one sample, one engine), and it says so on the page. Two more free tools sit alongside it: a backlink checker (domain rank, referring domains, top 100 links, competitor gap, CSV export) and a keyword research tool (100 related keywords with volume, difficulty, CPC and intent). Neither needs an account for the first run.
What the free plan adds: Ten scored opportunities every week — directories, roundups, comparison posts and ranked pages relevant to your category — with the authors behind them and their contact details. Plus an AI visibility snapshot across ChatGPT, Perplexity and Gemini, ten tracked prompts, and two tracked competitors. Where it stops: One company, one seat, and caps on opportunities, scans and drafts. Not a trial: No credit card, no expiry date. Starter is $79/mo if you outgrow it.
4. Ahrefs Free (Webmaster Tools)
The best backlink index in the business, free for sites you can prove you own.
What you get: Your backlink profile, referring domains, anchor text, a site audit and limited keyword data. Where it stops: Verified sites only — no competitor research — with limited crawl credits and report rows. Best used for: A far more complete picture of your own links than Search Console gives.
5. Google Analytics
What you get: Sessions, engagement, conversions, and which channels — including AI assistants, if you segment referrals — actually produce customers. Where it stops: Free tier limits only bite at high volume; the interface is the real cost. Pro move: Build a segment for referrals from ChatGPT, Perplexity and Copilot domains. That's your AI traffic baseline, free.
6. Screaming Frog SEO Spider
What you get: A full crawl of up to 500 URLs — broken links, redirect chains, duplicate titles, missing meta, outbound links. Where it stops: The 500-URL cap and no scheduled crawls. Pro move: Crawl a resource page on someone else's site, find its dead outbound links, and offer your page as the replacement. The tactic is in broken link building.
7. Google Trends
What you get: Relative demand over time, seasonality, breakout queries, regional differences. Where it stops: Relative not absolute volume, so it won't size a market. Best used for: Deciding whether a rising term is real or a blip before you write for it.
8. PageSpeed Insights
What you get: Core Web Vitals with field data and specific fixes. Where it stops: One page at a time; recommendations are technical and sometimes need a developer. Best used for: Your highest-traffic templates, not every page.
9. Moz free tools
What you get: Domain Authority checks for any site, limited Link Explorer queries, a keyword explorer with daily caps, and the MozBar extension. Where it stops: Query caps arrive quickly. Best used for: Vetting a site before you pitch it, and DA numbers stakeholders recognize.
10. AnswerThePublic
What you get: The questions people actually ask around a topic, mapped visually. Where it stops: A few free searches a day. Why it's more useful now: Those questions are close to how people prompt assistants — a free way to build the prompt list you'd track in an AI visibility tool.
11. Google Business Profile
What you get: Free control over how you appear in local search and Maps, plus reviews, photos, and query data. Where it stops: Local only, and it needs consistent upkeep. Best used for: Any business with a location or service area — still the highest-ROI free asset in local search.
A Complete Free Workflow
Week 1 — Baseline. Search Console, Bing Webmaster Tools, Ahrefs Free, Analytics. Note top queries, pages ranking 8–20, and your current backlink count.
Week 2 — Fix what you control. Screaming Frog crawl for broken links and redirects. PageSpeed Insights on your two most important templates. Rewrite titles for those positions 8–20 queries.
Week 3 — Find where to show up. Free opportunity shortlist plus Moz checks on candidate sites. Aim for 20 targets ranked by relevance, not authority.
Week 4 — Pitch and follow up. Send from your own inbox, personalized, and diarize a follow-up for seven days out — Backlinko's 12-million-email dataset shows a single follow-up produces 65.8% more replies.
Monthly. Re-check Search Console, ask assistants your buyer questions, and repeat week three.
That's a complete SEO practice at $0. The cost is about five hours a week.
When Free Stops Being Enough
When research eats more than half your time. Three hours of finding targets to send five emails is a bad trade against a $79 tool.
When follow-ups stop happening. The most common and most expensive failure.
When you need competitor backlink data at scale. The one job free tiers genuinely can't do — that's when Ahrefs Starter at $29 or Lite at $129 earns its place.
When you're managing several sites. Free tiers are single-site by design.

Common Questions
What is the best free SEO tool?
Google Search Console, by a distance. It's first-party data about your own site and no paid tool improves on it.
Are there free keyword research tools?
Yes, with caps: Search Console (queries you already rank for), Bing Webmaster Tools, Moz's keyword explorer, AnswerThePublic and Google Trends. Together they cover a small target list well.
Is there a free backlink checker?
Ahrefs Free for your own verified site is the most complete. For any other domain, Moz's free Link Explorer queries and Bing Webmaster Tools give you limited but real data.
Can I track AI visibility for free?
Partly. Ask ChatGPT, Perplexity and Gemini your buyers' questions manually and log the answers, or use a free plan that tracks a small number of prompts for you. Both beat guessing.
Do free tools give worse data?
Usually less data, not worse data — free tiers show a subset of the same index. Treat counts as a floor rather than a total.
What should I pay for first?
Whatever removes the most hours from your week. For most people that's research and contact finding, not sending.
