Paid keyword tools are convenient, but their databases are estimates. Google knows exactly what people searched for — and it gives much of that away for free if you know where to look.
1. Autocomplete
Type your topic and read the suggestions. They are ordered partly by popularity. Add a letter or a preposition ("best VPN for …") to reveal dozens more.
2. People Also Ask
The expandable question box gives you the exact questions readers ask. Each one is a potential H2 heading — and an FAQ section that can earn rich results.
3. Related searches
The footer list is a second batch of angles generated from real query patterns. Collect them all before you open any tool.
4. Search Console positions 5–20
This is the highest-value free data you own. These pages already rank on page two; improving them is the fastest traffic win available. Filter the Performance report by position and export.
5. Queries you already get impressions for
Same report, sorted by impressions: keywords Google already associates with your site but where you get few clicks. Write a dedicated page for the best ones.
6. Google Trends for direction
Volume tools tell you size; Trends tells you whether a topic is rising, seasonal or dying. Check five years of data before committing to a topic.
7. Rising and Breakout queries
Trends’ Related queries section flags queries growing fastest. A "Breakout" label means growth over 5,000% — an early-mover opportunity.
8. Search the keyword and read the room
Look at what ranks. Listicles mean write a listicle; guides mean write a guide; product pages mean the keyword is commercial and hard for a blog to win. Intent beats volume every time.
9. Filter by reading level and word count
Open two top results and note their length and depth. Matching the depth of the top pages is more reliable than any difficulty score.
10. Forums and communities
Reddit, Quora and niche forums use the words real people use — not SEO vocabulary. Note the exact phrasings and use them as headings.
11. Competitor gaps
Search site:competitor.com to list their topics, then look for subjects they have not covered. Free, fast, and often the best content ideas you will find.
12. Your own search box
If your site has one, check what visitors type there. It is a direct line to what your existing audience wants next.
How to organise it
Keep a spreadsheet with columns for keyword, intent, difficulty (your judgement from the SERP) and the page you will create or improve. Sort by opportunity rather than volume. Twenty well-chosen keywords beat two hundred random ones.
When to pay
Pay when you need competitive backlink data, historical volume at scale, or automated rank tracking. Until then, free data plus judgement is genuinely enough.
