Semrush: see the whole battlefield

Semrush's strength is data breadth. The SEO plan covers 5 websites, 500 tracked keywords, Position Tracking, Site Audit and basic AI-search monitoring. Starter adds deeper keyword and competitor tools, MCP access so AI assistants can query Semrush data, 300 AI visibility reports a day and an AI-ready Site Audit. Pro+ adds historical data, content optimization, cannibalization analysis and multi-location tracking. Add-ons include white-label Pro Reports ($20/month) and an Agency Partners listing ($90/month).

Surfer: turn briefs into cited content

Surfer is built around the writer. Its Content Editor's live guidelines, Content Score, the Surfy AI assistant, a humanizer, plagiarism checks and 1-click optimization push a draft toward what ranks. Topical Map plans content clusters, and Content Audit flags rank drops and refresh opportunities. The AI Tracker reports visibility score, mention gaps and brand sentiment. Integrations scale by plan: WordPress and Google Docs, then Contentful, then Zapier.
