What to check before you buy
The score is a proxy, not a target. What matters is the quality of the underlying SERP analysis, whether briefs can be handed to writers, and how well the editor fits your existing workflow.
The failure mode of this category: Chasing a content score to 100 produces keyword-stuffed prose that reads badly to humans and to AI engines. Treat the score as a checklist of missing subtopics.
- Write down the job. One sentence, in your own words, describing what should be different in ninety days. Tools that do not move that sentence are not candidates however good they look.
- Price the tier you actually need. Not the entry tier, the one that unlocks the feature you came for.
- Use the trial on real work. Same keyword, same page, same brief you would have used anyway.
- Check the exit. What happens to your data if you cancel in month four.
