Keyword research is easy to make complicated. This guide covers the exact workflow we use for real content plans, tool-agnostic and repeatable.
1. Start with seed intent
Write down what your site solves in one sentence. Every keyword you pursue should map back to that sentence.
2. Expand with a keyword tool
Feed seed terms into Ahrefs, Semrush, Mangools or LowFruits and pull related keywords, questions and long-tails.
3. Score by traffic potential, not volume
Ahrefs's traffic potential metric is our default โ it accounts for the parent topic, not just the exact match.
4. Sanity-check difficulty
Never trust the score alone โ always inspect the SERP for domain authority and content freshness.
5. Cluster into topics
Use WriterZen or the manual clustering trick โ group by SERP overlap, not by word similarity.
6. Build the calendar
Prioritise winnable clusters first; sequence supporting pieces before hubs.
