Surfer
What users love

- Price increases over time and Surfer AI cost adds on top of the base plan (per G2 reviews)
- No proper free trial — only a 7-day money-back guarantee on first purchase (per G2 reviews)
- Learning curve for using recommendations strategically rather than mechanically following the score (per G2 reviews)
- Very competitive niches still require manual SEO judgment beyond tool suggestions (per G2 reviews)
