You don't need an expensive SEO tool to find keywords you can actually rank for. You need to look in the right places. Here are five free sources that consistently surface low-competition terms.
1. Your own Google Search Console
The best source you already have. Go to Performance → Queries. Filter for queries where your average position is between 8 and 20. Those are terms Google has decided you're relevant for — you just need a stronger page to climb.
For each of these, click through to see which URL is ranking. Update that page, add internal links, and watch positions improve. This is the single highest-ROI keyword research activity for most sites.
2. People Also Ask and autocomplete
Type your seed keyword into Google. Look at the People Also Ask box. Each question is a long-tail keyword with weak competition, because most pages don't optimize for them specifically. Build one section per PAA question into your main page.
3. Competitor gap analysis (free)
Use a free tool like Ahrefs Webmaster Tools or Semrush free trial. Enter a competitor domain → Organic Research → filter for keywords where they rank in positions 4-10. Those are terms with established demand but weak top results — exactly what you want to target.
4. Reddit, Quora, and forum threads
Search Reddit for "[your topic] recommendation" or "[your topic] how to." Every question thread is a content gap. If the same question appears 10 times across Reddit, Quora, and a niche forum, build a definitive page answering it.
5. "Best of" comparison terms
Queries like "[product A] vs [product B]" almost always have lower competition than the head terms for either product individually. They're also extremely high commercial intent. Build comparison pages for every relevant pair in your niche.
How to validate a candidate keyword
Before writing, check three things:
- Open an incognito window and search the term. Are the top 5 results comprehensive, or thin?
- Are there big brands dominating (Amazon, Forbes, NYT)? If yes, it's probably too hard.
- Does the SERP show ads? Ads mean commercial value worth chasing.
If all three check out, write the best version of that page you can — then update your homepage, see our homepage optimization guide.
