Surfer

Surfer helps content teams write and update pages that rank in Google and get picked up by AI answers. Its content editor compares your draft with the pages that already rank and gives clear guidelines on terms, structure and length, so writers know exactly what to add.

Around that sit tools for keeping content healthy: content audits for existing pages, topical maps for planning clusters, cannibalization reports that flag pages competing with each other, automated internal linking, a plagiarism checker and an AI detector and humanizer. The AI Tracker shows how your brand appears in ChatGPT, Gemini, Perplexity and Google AI Overviews, and is also sold on its own for teams that only need AI search data.

Surfer works with WordPress, Google Docs, Contentful and Zapier, depending on the plan. It is used by agencies, in-house teams and freelancers, and says it has more than 150,000 customers in 159 countries.

Discovery starts at $49 a month billed yearly, Standard is $99, Pro is $182 and Peace of Mind is $299, with more documents, tracked pages, AI Tracker prompts and seats at each step. Enterprise is custom, and you can start for free.
