What’s the best free SEO tool I can rely on right now?

General

I’m trying to grow a small website on a tight budget and I’m overwhelmed by all the different SEO tools out there. I’ve tried a few free trials, but most features are locked behind paywalls and I can’t tell which free options are actually useful for keyword research, basic audits, and tracking rankings. Can anyone recommend truly effective free SEO tools and how you use them day to day?

Short answer from someone cheap and tired of paywalls: use a combo, not one tool.

If you want only one “best” free tool for a small site, go with Google Search Console.

Here is how I would set up a free stack that covers almost everything:

  1. Google Search Console
    Core for your site.

    • See search queries that bring traffic.
    • Check CTR and average position.
    • Find pages with impressions but low clicks.
      Action:
    • Sort by “Pages” then “Impressions”.
    • Pick a page with high impressions, low CTR.
    • Improve title and meta description to match top queries in the “Queries” tab.
    • Resubmit URL to get it indexed faster.

  2. Google Analytics 4

    • See which pages bring traffic and engagement.
    • Check which sources bring good users.
      Action:
    • Find pages with traffic but low engagement.
    • Improve content, add internal links, add clearer headings.

  3. Google Keyword Planner
    Yes it is built for ads, still works for SEO.

    • Use “Discover new keywords”.
    • Put in 2–3 seed phrases for your niche.
    • Filter by country and language.
      Action:
    • Sort by “Avg. monthly searches”.
    • Look for long phrases with lower competition.
    • Use these as headings and subtopics on your content pages.

  4. Ahrefs Free Tools
    The full suite is paid, but the free stuff helps.

    • Ahrefs Webmaster Tools for your site.
    • Free Keyword Generator for new content ideas.
    • Free Backlink Checker for your domain and competitors.
      Action:
    • Plug in a competitor.
    • See their top backlinks.
    • Check if you can get similar links, like directories, niche blogs, forums.

  5. Ubersuggest Free Tier
    Limited daily searches, still decent for a small site.

    • Get keyword ideas and simple difficulty scores.
      Action:
    • Compare 3–5 target keywords between Ubersuggest and Keyword Planner.
    • Pick the ones with ok volume but not insane difficulty.
    • Make one strong page per topic, not many tiny pages.

  6. Screaming Frog Free Version
    Free up to 500 URLs per crawl.

    • Find broken links, missing titles, duplicate titles, missing H1.
      Action:
    • Fix 404 links.
    • Give each page a unique title and H1.
    • Add meta descriptions to key pages.

  7. On-page SEO routine with no spend
    Use this checklist for each new page:

    • One main keyword in title, H1, first paragraph.
    • 2–4 related phrases inside content.
    • Clear headings.
    • Internal links from at least 2 other pages.
    • One clear meta description written for humans.

If you want only one tool to “rely on” daily, use Google Search Console. Pair it with occasional checks in Ahrefs free tools and Screaming Frog.

Everything else is optional. The main thing is consistent content and internal linking, not more tools.

You’re not crazy, the “free” tool ecosystem is mostly just paywall demos with extra steps.

I mostly agree with @boswandelaar on using a stack, but if you’re asking “what can I rely on” as a small site, I’d actually split it like this:

  • One “truth” tool for how Google sees your site
  • One “brains” tool for what to create next

For the first, yeah, Google Search Console is non‑negotiable. On that we all agree. But I wouldn’t call it the best single free tool if you’re still figuring out what to write. It’s great once you already have some traffic.

For early growth, the most underrated free option right now is:

AnswerThePublic (used very strategically)

Not perfect, but for content ideas on a budget, it’s stupidly useful if you avoid getting lost in the noise:

  1. Pick one main topic you want to rank for this month (like “home coffee roasting”).
  2. Drop it into AnswerThePublic, choose your country.
  3. Ignore the pretty wheels, switch to “Data” view.
  4. Export the list, then:
    • Keep questions that show clear intent: “how to…”, “best… for”, “vs”, “worth it”, “cheap…”.
    • Delete all 1‑word or super broad terms that would be insane to compete on.
  5. Group related questions into one strong article instead of 20 tiny ones:
    • “how to start home coffee roasting”
    • “home coffee roasting equipment”
    • “is home coffee roasting worth it”
      → one long guide with sections answering each.

Pair that with:

  • Search Console to:
    • See which of those pages actually get impressions.
    • Find “weird” long‑tail queries you didn’t plan but are already showing for.
  • Page source + common sense instead of 800 tools:
    • Check your own titles and H1s for clarity and relevance.
    • Check competitors’ pages manually rather than obsessing over 12 different “difficulty” scores.

Where I slightly disagree with @boswandelaar: you don’t need all those tools for a small site in the beginning. Screaming Frog, Ubersuggest, Ahrefs free bits… nice to have, but easy way to spend 4 hours analyzing and 0 hours publishing.

If you’re tight on time and money, a minimal, realistic setup:

  • Daily / weekly “rely on” tool: Search Console
  • Content planning: AnswerThePublic + manual Google searches (people also ask, related searches)
  • Tech sanity check: occasionally run a free site audit from any tool, fix the obvious stuff, then ignore the rest

Everything else is shiny-object syndrome disguised as “SEO research”. The tool is not what grows the site. Hitting publish on focused, actually helpful pages does.

Short version: there is no single “best free SEO tool,” but if you want one central tool to rely on for growth decisions, I’d actually put Google Search Console in that spot, not AnswerThePublic. Then you bolt on a couple of tiny helpers instead of a whole zoo of freemium platforms.

Where I partly disagree with @boswandelaar and the other reply: for a very small site, idea-generation tools are nice, but they can trick you into writing content no one ends up seeing. I’d flip the order:

  1. Search Console as your core “truth + ideas” tool
    Once you have even a handful of indexed pages, GSC starts telling you:

    • What queries you already show up for
    • Where you are stuck on page 2–3
    • Which pages get impressions but poor clicks

    Those are free content ideas:

    • Turn “accidental” long-tail queries into dedicated sections or posts.
    • Rewrite titles and meta descriptions to match the exact wording people use.
      This is not just measurement. It is also ideation that is based on real data, not theoretical keyword graphs.

  2. Free SERP checks instead of generic keyword tools
    Instead of obsessing over keyword difficulty, open an incognito window, search your target term, and study:

    • What type of page ranks (guide, product, comparison)
    • How long those pages are, how they structure H2s and H3s
    • What they cover that you do not
      A lot of free tools try to approximate this. You can get it 100% accurate just by looking at the results.

  3. Occasional use of “topic” tools like AnswerThePublic
    Here I actually agree with @boswandelaar’s general stack idea, and partially with the ATP suggestion in the other answer, but with a warning: these tools are fantastic at overwhelming beginners.
    Used lightly:

    • Grab a topic
    • Pull a list of questions
    • Keep 10–20 that clearly show intent
      Then close the tab. Do not sit there mining 400 variations that will never become real content.

  4. Regarding the product title “”
    Since there is no actual product attached to that name here, I’ll treat it the way I would any new free SEO tool someone stumbles across:

    Pros of using “” as a hypothetical free SEO tool

    • If it genuinely offers unlimited data on a free plan, it might replace several partial tools.
    • Could be useful for centralizing tasks: tracking rankings, doing quick audits, generating topic ideas.
    • If it has a clean interface, beginners can avoid the “enterprise dashboard” confusion that many SEO suites create.

    Cons of relying on “”

    • New or unknown tools often have smaller data sets than established platforms.
    • If the free plan is generous today, it might shrink later once they push harder for paid upgrades.
    • You risk building your workflow around a product that might pivot, shut down, or heavily gate features behind a paywall.

    So if you test something like “”, make it a supporting tool at first. Your main “rely on” source of truth should still be data coming straight from Google plus your own SERP checks.

  5. Minimal viable stack on a tight budget

    • Core: Google Search Console
    • Support:
      • Manual Google searches
      • A light topic tool like AnswerThePublic once in a while
      • Any free site audit tool once a month just to catch glaring technical problems

Publish more, tweak based on Search Console, and avoid turning “tool research” into your full-time hobby.
