Overview

What are Keyword Research Tools?

Keyword research is the foundation of every organic-growth program. Before you write a word or build a page, you need to know what people type into Google, how competitive those terms are, and what searchers expect to find. Guess wrong and you pour effort into pages no one is looking for — or pages you can't realistically rank for.

The tools below take the guesswork out of that first step. Gauge ranking difficulty on a simple 0–100 scale, check term frequency in your drafts to avoid over-optimisation, and classify keywords by intent so every page targets the right stage of the journey. Use them together to build a prioritised keyword map you can actually execute against.
