What is search intent and why does it matter more than keyword volume?

Search intent is what someone is actually trying to accomplish when they type a query. It matters more than search volume because a page that ranks for a high-volume keyword while misreading the intent will rank badly, convert badly, or both.

The commonly used categories:

Informational — the searcher wants to know something. "How does compound interest work." They want an explanation, not a product.

Navigational — they want a specific site. "Barclays login." You cannot usefully compete for someone else's navigational queries.

Commercial investigation — they are researching before buying. "Best noise cancelling headphones", "X vs Y". They want comparison and evidence.

Transactional — they are ready to act. "Buy", "price", "near me", "discount code".

Why volume alone misleads. A keyword with 50,000 monthly searches and informational intent will not sell anything, however well you rank. A keyword with 200 searches and transactional intent may be worth far more. High-volume head terms are also the most competitive, while longer, more specific queries are easier to rank for and usually indicate someone further along.

How to determine intent reliably: look at what already ranks. Search engines have vast behavioural data about what satisfies a query, and the current top results are their best answer. If page one is entirely long-form guides, a product page will not break in — the intent has been settled and you are proposing the wrong format. If it is all comparison lists, publish a comparison.

Intent also dictates format, not just topic: length, whether you need a table, whether video appears, whether the answer is a paragraph or a checklist.

Watch for mixed intent, where results contain several types — that usually means the query is ambiguous, and there is room for more than one kind of page.

Intent shifts over time; re-check rather than assuming.
