- Add Google Keyword Planner for volume ranges on keywords you do not rank for yet.

- Best overall: Semrush Keyword Magic Tool — largest database, $139/mo.
- The real skill is reading the search results page, not reading a difficulty score.
Free tools, ranked by how much they matter
Google Search Console
Free foreverThe single most valuable SEO tool that exists, and it is free. It shows every query that produced an impression for your site, your average position, and your click-through rate. That last number is where the easy wins live: a page ranking 8th with a 0.5% CTR usually needs a better title, not more backlinks.
Google Keyword Planner
Free with an Ads accountVolume ranges straight from Google. Without active ad spend the ranges are coarse — '1K-10K' is a wide bucket — but it is authoritative about relative demand and costs nothing.
Ahrefs free plan
Free forever, limitedSix tools at reduced limits, no card required. Useful for spot-checking a competitor's backlinks or your own site health without a subscription.
Google autocomplete and People Also Ask
FreeUnderrated. Type your topic into Google and read the suggestions and the People Also Ask box — those are real queries, phrased the way real people phrase them, with no tool between you and the data.

A process that actually works
Tools give you candidates. This is how you turn candidates into pages worth writing.
- Start from a question you can answer better than anyone. Not from a keyword list. Expertise is the only durable advantage a small site has.
- Check Search Console for what you already almost rank for. Queries sitting at positions 8-20 are the cheapest wins on your entire site — the page exists, Google already shows it, it just needs to be better.
- Expand with a tool. Take the topic and pull long-tail and question variants. Look for specificity, not volume.
- Open the actual search results. This is the step people skip and the one that decides everything. Who ranks? Do their pages truly answer the query, or are they thin listicles? If you can visibly do better, difficulty scores do not matter.
- Check intent before writing. If page one is all product pages, a blog post will not rank there no matter how good it is — and vice versa.
- One primary keyword per page. Two pages targeting the same query compete with each other, and you lose both.
Why difficulty scores mislead
Every tool computes keyword difficulty differently, mostly from the backlink profiles of pages currently ranking. That means the same keyword routinely scores 25 in one tool and 48 in another, and neither number knows whether those ranking pages are actually good.
A “difficult” keyword whose page one is eight years old and badly written is an opportunity. An “easy” keyword owned by a brand with a dedicated product page is not. Read the results page. It takes thirty seconds and is more reliable than any score.
FAQ — keyword research
What is the best free keyword research tool?
Google Search Console, and it is not close — it shows the actual queries bringing impressions to your site, their average position and their click-through rate. No paid tool has that data about you. Google Keyword Planner adds volume ranges for keywords you do not rank for yet, and Ahrefs' free plan fills in basic competition checks.
Do I need to pay for a keyword research tool?
Not to start. A new site's problem is not finding keywords — it is having enough content and authority to rank for any of them. Free tools are sufficient for the first twenty or thirty posts. Pay once research speed genuinely limits how fast you can publish.
What is keyword difficulty and can I trust it?
It is each tool's estimate of how hard ranking on page one would be, usually scored 0-100 and driven mostly by the backlink profiles of pages already ranking. Treat it as a rough sort order, not a fact — the same keyword often scores very differently across tools because each uses its own index and formula.
How do I find low-competition keywords?
Look for longer, more specific queries with clear intent, and check the actual search results rather than trusting a score. If page one is full of forum posts, thin listicles and pages that do not directly answer the query, you can compete regardless of what the difficulty number says. If it is dominated by major brands with dedicated pages, move on.
Is Google Keyword Planner accurate?
It is accurate about what it measures, which is advertising demand in broad ranges. Without an active ad spend it buckets volumes coarsely — a keyword showing '1K-10K' could be either end. Use it for direction and relative comparison, not precision.
What is the cheapest paid keyword tool worth buying?
Mangools, at about $29.90/month. Its KWFinder does keyword research properly and the bundle includes rank tracking and basic backlink data. It is roughly a fifth of Semrush's price and covers what a solo blog actually uses.
How many keywords should one article target?
One primary keyword and whatever closely related variants fit naturally. Modern search engines understand synonyms and related concepts, so an article that answers a question thoroughly will rank for dozens of variations without you listing them. Writing separate thin posts for near-identical keywords creates cannibalisation, not coverage.
Should I target keywords with no search volume?
Sometimes, yes. Tools under-report volume for new topics, regional queries and anything phrased conversationally — and 'zero volume' often means 'below the tool's reporting threshold', not 'nobody searches this'. If a query is one your actual customers ask you, it is worth a page.
