What our research says

Keyword Insights

Buy it for the clustering engine, which is genuinely better than doing SERP-overlap grouping yourself in a spreadsheet; treat the AI writer as a bonus rather than a reason. Agencies planning content hubs across many sites get the most out of it, solo bloggers publishing four posts a month will burn less money on Surfer or Frase.

Pros

  • SERP-overlap clustering is the core competency and it is fast at scale
  • Public API means clustering can be driven from your own scripts
  • Basic plan ships 10,000 credits, enough for a real clustering job not a demo
  • Discovery pulls from Reddit, Quora and PAA, not just a keyword database

Cons

  • No free tier - entry is a paid $1 trial that ends in pay-as-you-go
  • Basic is single-seat, so any team needs the $99 Professional plan
  • Full agent-written articles cost 1,200 credits, which drains an allowance quickly
  • Volume and difficulty data is thinner than Ahrefs or Semrush

SEOcluster.ai

SEOcluster.ai's edge is starting from actual Search Console performance data instead of third-party keyword databases, so clusters reflect queries the site already ranks for rather than generic volume estimates. It's built for sites with meaningful existing GSC history; a brand-new site with little search data won't get much out of the clustering.

Pros

  • Clusters use actual ranking queries from GSC rather than estimated search volume
  • Cannibalization detection scores overlap severity instead of just flagging it
  • Content briefs include FAQs and internal link suggestions, not just an outline

Cons

  • Usefulness depends entirely on how much Search Console history the connected site has
  • Free plan caps out at 1,500 keywords, too small for most established sites
  • No company location or team background published
