How to do keyword analysis for SEO

Keyword analysis starts with understanding search intent and volume at scale. Begin by identifying seed keywords—broad terms related to your client's business, products, or services. Use tools like Ahrefs, SEMrush, or Moz to pull related keywords and their monthly search volume, keyword difficulty scores, and current ranking positions. The goal isn't just finding high-volume terms; it's finding terms where your client can realistically rank and where the people searching actually want what you're selling. A 5,000-search-per-month keyword is worthless if the searcher is looking for free information and your client sells premium services.

Next, organize keywords by intent and funnel stage. Transactional keywords (people ready to buy) like "best project management software for teams" should get priority over informational keywords like "what is project management." Group keywords by topic cluster—these become your content pillars and supporting pages. For a web design agency, you might organize around clusters like "web design for ecommerce," "web design for nonprofits," and "web design process," each with 5-15 related keywords at different funnel stages. Map these to existing pages or plan new content around them. This prevents keyword cannibalization where multiple pages compete for similar searches, which dilutes ranking power.

Finally, analyze what's actually ranking now. For your target keywords, look at the top 10 results and assess their content length, content type, backlink profiles, and on-page optimization. This shows you what Google considers relevant for that query. If every result is a blog post and you're planning a product page, you need to reconsider your approach. Similarly, if the top-ranking pages all have 2,000+ words and yours has 800, you know what competitive bar you're facing. This competitive analysis reveals gaps too—maybe existing content doesn't properly address certain angles, giving you an opportunity to create something better. Track these insights in a spreadsheet alongside search volume and difficulty to prioritize which keywords offer the best return on content investment. Update this analysis quarterly since search landscapes shift and your rankings change.
