Free SEO Tools That Stay Free: A Stack Built by Job

Most lists of free SEO tools are really lists of free trials: three searches a day, a 100-page audit cap, a keyword column hidden behind an upgrade button. If you run SEO for one site on no budget, you need a stack that still works in month six. This one is built by job, uses tools that are free at the point of use, and says what each one asks of you (an account, a verified site, billing details) before you depend on it.

Two rules shaped the picks. First, the tool has to answer a real question on its own, without a paid plan to make the output usable. Second, every limit listed here comes from the provider's own documentation or product page, checked in October 2026. Free tiers change, so treat the limits as a snapshot and re-check before you build a process on one.

Speed and Core Web Vitals	PageSpeed Insights	Nothing	Field data needs enough real Chrome traffic
Keyword volume	Google Keyword Planner	Google Ads account with billing details	Volumes are estimates; very low-volume terms are hidden
Keyword ideas with difficulty and intent	CrawlTide Keyword Generator	Nothing, no signup	Up to 50 ideas per seed
Structured data eligibility	Rich Results Test and Schema.org validator	Nothing	One URL at a time
Single-page technical checks	CrawlTide free tools	Nothing, no signup	One page per check, not a full-site crawl

Start with the data only Google and Bing can give you

No third-party tool sees your real impressions and clicks. Search engines do, and they hand that data over for free once you verify the site. Set these two up before anything else, because the history only starts accumulating from the day you connect.

Google Search Console: your actual queries, pages and clicks

Search Console's Performance report lists the queries your pages appeared for, with impressions, clicks, click-through rate and average position. Google's Analytics help documentation states that Search Console keeps data for the last 16 months, so export anything you want to compare year over year before it ages out.

The most useful free move in the whole stack: filter the Performance report to queries where your average position is between 8 and 20. Those are pages Google already considers relevant that sit just off the first screen. Improving one of those usually beats writing a new post from scratch.

Search Console now also reports AI search. On 3 June 2026 Google introduced Search Generative AI performance reports, covering impressions in AI Overviews, AI Mode and generative features in Discover, with breakdowns by page, country, device and date. A note on the Search Central announcement says the reports reached all websites worldwide as of 31 August 2026. They show impressions only, so treat them as a visibility signal, not a traffic report.

Bing Webmaster Tools: a second index and Copilot citations

Bing Webmaster Tools gives you the Bing equivalent of the Performance report, plus crawl and indexing diagnostics. Its bigger draw in 2026 is AI Performance, a public preview Microsoft announced on 10 February 2026. It reports how often your pages are cited in Microsoft Copilot, Bing's AI-generated summaries and some partner integrations, with page-level citation counts and the grounding queries behind them.

Read it with the caveats Microsoft gives: grounding queries are a sample, and a citation count says nothing about placement in the answer or about clicks. It is still the only free, first-party view of AI citations from a major engine.

Keyword research without a subscription

Free keyword research has one hard problem: volume data costs money to collect, so most free tools either hide it or ration it. You have two workable options.

Google Keyword Planner is free inside Google Ads, but Google's help documentation says you must complete account setup by entering billing information to use features like "Get ideas for new keywords". You do not have to run a campaign. Google describes the monthly numbers as estimates, and says keywords with very low search volume are not discoverable, which is exactly where many small-site opportunities live.

The CrawlTide Keyword Generator takes a seed keyword and a country and returns up to 50 ideas with monthly volume, CPC, keyword difficulty and intent, straight from DataForSEO, with no account. If you then need to decide which ideas deserve their own page, paste the list into the keyword clustering tool to group them by intent.

Google Trends rounds this out. It shows relative interest over time rather than absolute volume, which makes it the right tool for one specific question: is this topic growing or fading before I spend a week on it?

Technical checks you can run on any single page

A full-site crawl of a large site is the one job that genuinely needs paid software. Most day-to-day technical questions are about one page, though, and those are free to answer.

• "Why is this page not indexed?" The indexability checker reports HTTP status, redirect chain, robots meta, X-Robots-Tag header, canonical and sitemap presence in one pass. Then confirm with the URL Inspection tool in Search Console, which shows Google's own view.
• "Are links on this page dead?" The broken link checker tests the first 50 links on a page for 4xx and 5xx errors, redirects and timeouts.
• "Is this page fast for real visitors?" PageSpeed Insights shows two kinds of data. Field data comes from the Chrome UX Report and reflects real users over the previous 28-day collection period. Lab data is a Lighthouse run on a simulated device. When they disagree, trust the field data for ranking questions and use the lab data to find the cause.
• "Can search engines read my robots.txt and sitemap?" The robots.txt and sitemap checker confirms both exist, are reachable and parse cleanly.

Structured data: two Google-side checks and one gap finder

Google's Rich Results Test tells you whether markup on a URL qualifies for a rich result in Google. The Schema.org validator checks the markup against the vocabulary itself, including types Google does not reward. Neither tells you what a page is missing entirely, which is the question that matters when you are planning. The schema markup checker lists every JSON-LD type on the page and flags high-value types that are absent. For when to reach for which, see our comparison of schema markup testing tools.

One date to remember before you add markup for a rich result: Google stopped showing FAQ rich results for every site on May 7, 2026, after limiting them to well-known government and health sites in 2023. FAQ markup will not earn an expandable result anymore, whatever an older tutorial says.

Where free SEO tools stop being enough

Every tool above answers a question about one page, one keyword or one moment. None of them watches the whole site over time and tells you what changed. That is the point to look at a platform, not before: when you are checking the same ten pages every week by hand, or when a ranking drop shows up in Search Console and you cannot tell which change caused it.

Signs you have outgrown the free stack:

• You need a crawl of every page, not spot checks, because the site has grown past what you can review by hand.
• You want rank and AI visibility history for keywords you do not rank for yet, which Search Console cannot show.
• You are reporting to a client or a manager and rebuilding the same spreadsheet each month.

If you get there, our write-up on what a full SEO platform adds covers site audits, backlink monitoring and reporting in one place. Until then, the free SEO tools here cover more ground than most small sites ever use.

A one-hour setup order for a new site

1. Verify the site in Google Search Console and submit the sitemap.
2. Verify the same site in Bing Webmaster Tools.
3. Run the homepage and your top three landing pages through PageSpeed Insights and note any failing field metric.
4. Run the same pages through the indexability checker and schema markup checker.
5. Pull 50 keyword ideas for your core topic, cluster them, and pick one cluster for your next page.
6. Set a calendar reminder for four weeks out to read the Search Console Performance report, once it has data worth reading.

Start with step one today, because it is the only one where waiting costs you data. Then open the full set of free CrawlTide tools and run your homepage through the SEO score checker to see what to fix first.
