How to choose the right keywords for SEO

A practical guide to keyword research — how to find, evaluate, prioritise, and use keywords naturally to rank higher and attract the right visitors.

What are keywords?

Keywords are the words and phrases people type into search engines to find information. In SEO, you use them in your content to rank for what your audience is searching for. There are three main types:

• Short-tail keywords: one or two broad words, like "shoes" — high volume, very competitive.
• Long-tail keywords: three or more specific words, like "best running shoes for women" — lower volume, easier to rank, higher intent.
• Branded keywords: terms that include your brand name, like "Nike shoes."

Long-tail keywords are usually easier to rank for and more effective at driving targeted, ready-to-act traffic.

Why are keywords important for SEO?

Keywords help search engines understand what your pages are about. When someone searches, the engine looks for pages relevant to that query — so if your content targets the right keywords, you're far more likely to appear in those results.

How to choose the right keywords

• Identify your target audience — who they are, what they care about, and what they search for.
• Do keyword research with tools like Google Keyword Planner, SEMrush, or Ahrefs.
• Consider search intent — match keywords to whether users want information, a product, or a service.
• Look at search volume — aim for solid demand without being impossibly competitive.
• Evaluate competition — target terms you can realistically rank for.
• Use a variety of keywords, including long-tail terms, rather than chasing one or two.
• Use keywords naturally in your content, never stuffed.
• Track results and refine over time.

Keyword research: find, evaluate, prioritise

How to find keywords

• Use keyword research tools to get volume, competition, and related terms.
• Mine your own analytics for terms already driving traffic.
• Study competitors' title tags, meta descriptions, and ranking keywords.
• Use your own knowledge of the questions and problems your audience has.

How to evaluate keywords

Weigh search volume against competition, match keyword intent to your audience, and balance long-tail terms (specific, easier to rank) with short-tail terms (higher volume, harder to win).

How to prioritise keywords

Rank your keywords by a combination of search volume, competition, and intent. Prioritise terms that are achievable, aligned with your audience, and tied to business outcomes. A simple spreadsheet or keyword tool keeps this organised.

Using keywords in your content

How to use keywords naturally

• Include target keywords in your title tag and meta description.
• Use them throughout headers, body text, and image alt text — in context.
• Use variations, synonyms, related terms, and long-tail phrases instead of repeating one keyword.
• Use keywords in internal links to show search engines how your pages relate.

How to avoid keyword stuffing

Don't use keywords too often — it reads as spam and can hurt rankings. Write for people first, use keywords where they fit naturally, check density with a tool if needed, and always proofread before publishing.

Tracking and improving over time

• Choose a keyword-tracking tool that fits your needs and budget.
• Set it up with your site URL and target keywords.
• Track rankings, search volume, and click-through rate.
• Analyse what's working, watch search trends, experiment with new terms, and listen to your audience.

Conclusion

By finding, evaluating, and prioritising the right keywords — then using them naturally and tracking results — you can steadily improve your rankings and attract more of the right visitors. Keyword strategy isn't a one-time task; it's an ongoing process that compounds.
