Yoast SEO Keywords Tutorial
Guides you through choosing a focus keyphrase and entering it in Yoast SEO so the plugin can analyse and give on-page optimisation feedback.
If you have ever passed all Yoast checks and still failed to rank, you already know the plugin is a guide, not a ranking guarantee.
Key points
- Pick one focus keyphrase per page and stick to it.
- Check search intent and volume before committing to a keyphrase.
- Place the keyphrase naturally in the SEO title, introduction, subheadings, and meta description.
- Treat Yoast’s feedback as guidance, not a rulebook for ranking.
One keyphrase, two different outcomes
A site owner chose 'best running shoes' as the focus keyphrase for a product page. Yoast gave green lights for title, introduction, and meta description. The page still failed to rank because the search intent was informational, but the page was a sales page. A competitor used the same keyphrase on a buying guide, matched intent, and ranked in the top five within three months. The plugin checks were fine; the intent mismatch was the problem.
Three common mistakes that waste your effort
- Same keyphrase on multiple pages Targeting the same term on several pages confuses search engines and splits your ranking potential. Assign one primary keyphrase per page.
- Keyword stuffing to pass checks Forcing the keyphrase into every sentence just to satisfy Yoast’s analysis makes the text read unnaturally and can harm user experience.
- Ignoring search intent Choosing a keyphrase without checking what users actually want — information, a product, or a local service — leads to mismatched content and poor rankings.
Three things to check before you enter a keyphrase
- Search volume and competition Use keyword research tools to confirm people search for the term and that the competition is not overwhelming for your site’s authority.
- Intent alignment Google the term yourself and see what kind of pages rank. If they are all guides, do not target that term with a product page.
- Natural placement in key elements The keyphrase should fit naturally in the SEO title, first paragraph, subheadings, and meta description without sounding forced. Yoast SEO keyword density is a percentage it reports, but forcing that number up often hurts readability.
Common questions
What is a focus keyphrase in Yoast SEO?
It is the main keyword you optimise a page for, entered in the Focus keyphrase field so Yoast can analyse on-page elements.
Can I use the same keyphrase on multiple pages?
No. Yoast recommends assigning one unique keyphrase per page to avoid internal competition and confused search engines.
Does passing all Yoast checks guarantee rankings?
No. The checks are guidance; content quality, search intent, and competition still determine actual rankings.
