Quick definition
Keyword research is the process of finding and analysing the words and phrases people search for, so content can be built around real audience demand.
Keyword research is the practice of discovering the terms your target audience actually types into search engines, app stores, and increasingly into social platforms — then evaluating each term for search volume, competition, and relevance. It originated in search engine optimisation as a way to align web pages with real demand rather than guesswork. The core inputs are the same everywhere: what words describe the problem you solve, how many people search them, and how hard it would be to rank or surface for each. Modern keyword research also groups terms by search intent — informational, navigational, commercial, or transactional — so content can match what the searcher is actually trying to do.
Social platforms have grown into search engines in their own right. Many users now open TikTok, YouTube, or Pinterest to look things up the way they once used Google, which means the same discipline applies to captions, hashtags, video titles, and on-screen text. Creators research the phrases their niche searches for and work them naturally into hooks and descriptions so posts surface in platform search and suggested feeds. The overlap with hashtag research is significant, but keyword research is broader — it shapes the actual language of the content, not just the tags attached to it.
Start by listing the questions and phrases a customer would use, then expand the list with autocomplete suggestions, related searches, and competitor content. Prioritise terms where intent matches your offer and competition is realistic for your account size. Rather than chasing the highest-volume keyword, many strategists target specific long-tail phrases that signal clearer intent and face less competition. Revisit the list regularly, because search behaviour and platform trends shift over time.
