Keyword Finder
Generates a list of related search terms from a seed keyword, adding metrics like volume and difficulty to help you prioritise which queries to target.
If you have ever picked a keyword on a low score and still failed to rank, you already know the number is not the whole story.
Key points
- Start with a seed term that matches your topic, not your brand name.
- Filter suggestions by search intent before you look at volume.
- Ignore keywords where the top results are all big-brand pages you cannot beat.
- Use at least two keyword explorers to catch ideas one database might miss.
- Re-check keyword metrics every quarter because volume and difficulty drift.
The same seed, three different outputs
You enter 'running shoes' into three keyword finders. Tool A returns 120 suggestions with volume and difficulty; the top term is 'best running shoes for flat feet' at 2,400 monthly searches and a difficulty of 18. Tool B surfaces 90 terms but misses that long-tail phrase entirely. Tool C adds competitor URL analysis and shows you 'trail running shoes wide fit' — a term with 340 searches and a difficulty of 8. You would have missed it without multiple keyword research sources.
Three situations where this changes your decision
- Volume alone misleads A keyword with 5,000 searches may be dominated by Amazon or Wikipedia. The finder's keyword difficulty score tells you whether your site can realistically compete.
- Intent shifts the target A term like 'buy coffee maker' signals transactional intent. If your page is a blog post, the finder's suggestion is irrelevant — you need a product page.
- Long-tail beats head terms A broad term like 'SEO' has high volume but low conversion. The finder surfaces phrases like 'SEO for small business' that are easier to rank and more specific.
Four ways it goes wrong
- Chasing volume blindly Picking the highest-volume term without checking whether your content matches search intent leads to high bounce rates and zero rankings.
- Ignoring difficulty A keyword difficulty index of 80 on a term your site cannot rank for wastes time. Filter by realistic difficulty for your domain authority.
- Trusting one tool Each tool uses its own database. Suggestions vary widely, so relying on a single source means you miss alternative keyword sources like competitor pages, autocomplete data, or YouTube keywords.
- Treating suggestions as final Keyword lists are raw material, not targets. You must filter out irrelevant terms and group by intent before you can act on them.
What to check before you act
- Search intent Look at the top-ranking pages for the keyword. If they are all product pages and yours is a guide, the intent mismatch will kill your chances.
- Keyword difficulty Compare the difficulty score to your site's authority. A score of 30 may be easy for a strong domain but impossible for a new blog.
- Current SERP layout Google changes SERP features over time. A keyword that once returned ten blue links may now show a featured snippet or a video carousel, altering the opportunity.
Common questions
What is the best free keyword research tool?
There is no single best tool. Google Keyword Planner is free but designed for ads. For organic SEO research, try the free tiers of Semrush or Ahrefs, which offer limited daily searches.
What are the best keywords for a YouTube channel?
Focus on question-based and long-tail phrases that match your video content. Use a keyword explorer with a YouTube-specific filter, or check YouTube Autocomplete for real search behaviour.
