Keyword Research

Reveals and evaluates the search terms people use so you can build or adjust pages around real demand, intent, and competition.

If you have ever picked a keyword purely on volume and still failed to rank, you already know that number is not the whole story.

Key points

  • Start with seed topics from your business or audience, then expand using tools and search suggestions.
  • Evaluate search volume, competition, relevance, and intent together — never rely on volume alone.
  • Long-tail and question-based queries often offer lower competition and clearer intent.
  • Analyse competitor keywords to find gaps and underperformed terms they rank for.
  • Use keyword clustering to group related terms into topics and map one primary keyword per page with a few supporting terms.
  • Use Search Console data as your own SEO keyword research report to find impression-rich, low-click queries.

High volume does not mean high opportunity

A travel site targeted 'cheap flights' (110k monthly searches) with a thin page listing generic tips. The SERP was dominated by booking aggregators with rich results and price comparison tools. Despite the high volume, the page never reached page two because the intent was transactional, not informational. A competitor targeting the long-tail keyword 'how to find cheap flights' (2.1k searches) with a detailed guide ranked in the top five within three months.

Three things keyword research is not

  • Not a volume contest Choosing keywords only for high keyword search volume ignores intent and relevance. A keyword with 50k monthly searches may be worthless if searchers want a product you don't sell.
  • Not a one-time task Search intent, competitor content, and SERP features shift over time. Revisit your keyword lists quarterly to stay aligned with current demand.
  • Not a ranking guarantee Even a well-researched keyword can be unwinnable if your page lacks authority, depth, or alignment with the dominant SERP format.

Four common mistakes to avoid

  • Too many keywords on a page Assign one primary keyword and a small set of supporting terms per URL. Trying to rank for everything on one page dilutes focus and confuses search engines.
  • Ignoring search intent Informational queries need educational content; transactional queries need product or service pages. Matching intent is more important than matching exact keywords.
  • Neglecting competitor analysis Reviewing what competitors rank for reveals gaps and underperformed terms. It is an easy source of keyword ideas and content opportunities.
  • Relying solely on tool data Keyword research tools can disagree on volume and difficulty. Validate with Google Search Console and live SERP inspection before committing resources.

Three situations that change your keyword choices

  • SERP features dominate If the top results are all featured snippets, video carousels, or local packs, your page may need a different format or intent angle to compete.
  • Your page is thin A low-difficulty keyword can still be unwinnable if your page lacks depth. Invest in comprehensive content that fully answers the query.
  • Demand shifts seasonally Seasonal keywords require timing. Research historical trends and plan content publication to coincide with peak search periods, or you will miss the window entirely.
