What’s the best free keyword search tool to use right now?

General

The “best free keyword tool” is kind of a trap question. Nothing free is both accurate and unlimited, so your real edge is in how you combine imperfect stuff.

Since a lot of ground is already covered, here are different angles that pair well with what @chasseurdetoiles and the other reply suggested, without just rehashing SERPs + Search Console + Ubersuggest.

1. If I had to pick one starting point: Google Search Console… but used offensively

Everyone says “use GSC,” but most people only use it reactively.

How to turn GSC into a keyword finder:

  • Go to Performance → Search results
  • Filter by last 3–6 months
  • Sort by Impressions
  • Look for:
    • Queries where you are ranking between positions 8 and 25
    • CTR is low but impressions are real

These are:

  • Proof that Google already sees you as somewhat relevant
  • Often signs there are related long‑tails you have not covered

Then:

  • Group those queries by theme
  • Turn them into:
    • Separate support articles
    • Sections / FAQs inside your main article
    • Internal links with those exact phrases as anchors

This gives you “low competition” in practice, because you are expanding what already works rather than gambling on random keywords.

Disagreement angle:
I think relying too heavily on external difficulty scores (even for validation) slows people down. For a tiny site, your “KD” is usually:

Can I outdo the top 5 results in usefulness, clarity, and specificity?

That is something no free metric shows.

2. Brave Search & Bing as sneaky idea generators

Almost everyone stares at Google only. That is a mistake.

Brave Search and Bing autocomplete + “People also ask” style boxes can surface phrasing that does not show up the same way in Google.

Use them for:

  • Variations in wording
  • Extra modifiers people use
  • Regional phrasing that Google sometimes hides

Flow:

  1. Type your seed term into Brave or Bing
  2. Note the autocomplete phrases
  3. Compare those to Google’s autocomplete
  4. Target phrases that:
    • Appear across multiple engines
    • But show very weak Google SERPs

This is particularly good for tech, finance, and software queries where audiences are more likely to use non‑Google engines.

3. Competitor content gap method without paid tools

You can do a lightweight version of “content gap analysis” even without Ahrefs / SEMrush.

  1. Identify 3–5 competitors that:
    • Rank for your core topic
    • Are roughly your size or a bit bigger
  2. Manually crawl their key pages:
    • Their “best of” posts
    • Resource / hub pages
    • Category pages
  3. Extract:
    • H2 / H3 headings
    • Table of contents entries
    • FAQ blocks

Each heading is often a disguised keyword:

  • Turn headings into question or phrase variations you can target
  • Cross check:
    • Autocomplete in Google
    • “People also ask” boxes related to that heading

No fancy tool, just using their editorial choices as keyword research.

This goes further than the approach of just plugging seed keywords into tools, which is where I part ways a bit with the Ubersuggest‑heavy strategy.

4. Real‑world language mining: chat logs & support inboxes

One thing almost nobody does for small sites:

  • If you have:
    • Email questions from readers
    • Chat transcripts
    • Comments on your own posts
  • Mine those exact phrases

Use:

  • Their exact confusing wording as:
    • H2s
    • FAQ questions
    • Long‑tail article titles

Then:

  • Toss those phrases into Google autocomplete just to see if the wording lines up with broader search patterns

This beats chasing “0–10 searches/month” estimates, because you already know someone in your niche talks like that.

5. Thoughts on “best free tool” as a label

If I am forced to name a single “tool” for your situation, I still would not say a classic keyword tool.

I would pick:

  • Google Search Console as the core
  • Supplemented by:
    • Brave / Bing autocomplete
    • Manual competitor heading mining
    • Your own audience language

@chasseurdetoiles leans harder into structured tool use. That works, but if you are truly constrained, a manual, research‑heavy workflow can actually beat shallow usage of 5 different freemium products.

6. Quick sanity formula for low competition picks

Before writing on a keyword, run this simple checklist:

  • Top 5 results:
    • At least 1 thin / outdated / off‑topic page?
    • No ultra‑dominant brand “moat” like government docs or major institutions on all 10 results?
  • SERP type:
    • Actual articles are ranking, not just huge tools or product pages
  • Your angle:
    • Can you add one of:
      • Region / scenario specificity
      • Up‑to‑date information
      • Clear tutorial structure

If “yes” to those, I would write even if tools show tiny volume.

About the empty product title “”

Since there is no actual product name or tool there, I will treat it conceptually as if it were a free keyword research helper you are considering.

Pros of “” as a free keyword tool conceptually:

  • Cost: fits any budget
  • Flexibility: you define your own workflow using search data, not locked into rigid metrics
  • Scales: as your site grows, the same base methods (GSC, SERPs, competitor headings) keep getting more powerful

Cons of “” as a “tool”:

  • No single interface: you are stitching together methods manually
  • Learning curve: you need to build your own process instead of leaning on a dashboard
  • No hard “KD” number: you must get comfortable judging SERPs by eye

In other words, the “tool” you actually want is a repeatable process using free sources, not a magic button.

If you set up that process now, any later move to paid tools will feel like an upgrade, not a crutch.
