Finding hundreds of website content ideas fast with SEMrush

Executive overview

Most content teams exhaust obvious topic variations quickly and feel stuck. SEMrush Topic Research breaks out of keyword variations by mapping semantically related topics — not just synonyms.

Enter a broad or specific niche term, explore subtopics and questions, favourite the best candidates, then export to a writer.

The core insight: topic research generates adjacent ideas keyword tools miss — questions and subtopics with lower competition and higher relevance.

How topic research differs from keyword research

• Keyword tools return variations of the input phrase (e.g. "digital marketing for beginners")
• Topic Research surfaces indirectly related subjects (e.g. Facebook ads, email marketing, influencer marketing)
• Use it for brainstorming first; move to keyword tools later for search volume and difficulty

Working with subtopics and questions

• Each subtopic card shows combined search volume and difficulty for that cluster
• High difficulty on a subtopic signals the whole cluster may be too competitive — skip or choose a narrower angle
• Questions (e.g. "Why is email marketing important?") are typically top-of-funnel and less competitive than head terms
• Favourite promising topics directly from the interface to build an exportable list

Finding hidden gems with views and filters

• Trending subtopics tab surfaces topics gaining momentum rather than evergreen standbys
• Explorer view shows existing content performing well in the space — useful for benchmarking
• Overview tab lists top 10 headlines by backlinks and 10 popular questions at a glance
• Mind map view reveals tangentially related topics not visible in the card view (e.g. "potential customers" branching from "digital marketing")

Turning ideas into a content pipeline

• Export your favourited topics as a list to hand directly to a writer
• For long-tail targets, favourited questions can be used as article titles with minimal rephrasing
• Re-enter promising subtopics (e.g. "potential customers") into Topic Research or a keyword tool for a second layer of ideas
• Run both broad and specific searches to maximise topic range
