How to research keywords for your SEO strategy

Start by understanding your client's business model, target audience, and competitive landscape before touching a keyword tool. Talk to your client about who actually buys from them, what problems they solve, and where those customers currently search. This context matters more than any keyword volume number. Then use tools like Ahrefs, SEMrush, or Moz to extract keyword data from your client's existing ranking keywords and their competitors' organic traffic. Search for what keywords your competitors rank for in your industry using the "keywords" or "organic keywords" report—this shows you what's actually driving traffic in your vertical rather than guessing. You're not trying to copy competitor strategies wholesale; you're identifying gaps where your client can compete.

Build keyword clusters around search intent rather than compiling random lists. If you're optimizing for a digital marketing agency, you might find that "SEO services," "SEO agency," and "SEO consulting" all address the same buyer intent—attracting businesses wanting professional help. Group these together and target them across related pages instead of treating each as a separate ranking opportunity. Look at the search results for each keyword to see what content rank positions one through ten actually look like. If your client is a local service business and you're seeing national brand results dominating, that keyword might not be worth prioritizing. Conversely, if you see mostly blog content or directory listings ranking, you've found an opportunity where a well-optimized service page could win.

Finally, balance search volume with commercial intent and ranking difficulty. A keyword with 500 monthly searches and low difficulty beating keywords with 5,000 searches but dominated by high-authority sites. Use your tool's difficulty score as a starting point, but manually verify—sometimes small, long-tail variations have lower competition than their volume suggests. Map keywords to your client's actual service offerings and current content, then build a roadmap showing which pages should target which keywords and what new content gaps exist. This prevents the common mistake of optimizing for keywords your client can't actually convert on, which wastes effort and client budget.
