Surfer SEO is one of the most popular content optimization tools for Google. But optimizing for Google's NLP algorithm is different from getting cited by ChatGPT and Perplexity — and only Serpely does the latter.
Getting cited by ChatGPT and Perplexity depends on content structure, authority signals, and E-E-A-T — factors Serpely's GEO Score measures directly.
Serpely closes the loop: create, track, measure AI citations, reprioritize — the full content performance cycle in one platform.
Surfer SEO starts at $69/month and focuses solely on content optimization. Serpely starts free and covers rank tracking, technical audits, and AI visibility.
