Short version: they solve different problems. Surfer SEO is the gold standard for Google keyword optimization. Vectory is purpose-built for AI-engine citation across ChatGPT, Gemini, Perplexity, and Claude. Most serious teams use both — Surfer for organic-search clicks, Vectory for the AI-visibility channel that traditional SEO can't see.
Surfer's content editor scores your page against the top-ranking Google SERP. Vectory's Quality Gate scores your page against ~10 target prompts on ChatGPT, Gemini, Perplexity and Claude. If you only care about Google clicks, keep Surfer. If you care about being recommended by the AI engines that are eating Google's lunch — add Vectory.
Surfer's content editor is the most polished in the SEO category. NLP keyword scoring, term frequency, headings — all good defaults for Google-first content.
Their SERP analyzer pulls real top-10 patterns and surfaces them in a way that helps content writers ship in hours, not days.
Mature integrations (WordPress, Jasper, Google Docs, Contentful) and a large agency user base. Easy to plug into existing SEO workflows.
Vectory measures citation across ChatGPT, Gemini, Perplexity, Claude. Surfer is Google-SERP-only — it has no concept of LLM citation, source-attribution, or AI Share-of-Voice.
Vectory re-tests every page against target prompts on real LLMs and patches weak spots. Surfer's "score" is keyword-coverage, not citation-likelihood.
Vectory ships the AI-visibility plumbing (llms.txt, Schema.org, MCP server). Surfer doesn't generate any of those — it's a content scoring tool.
Diagnostic of why your entity wasn't cited (missing schema, weak source, factual gap, brand-mention deficit) on each engine. Surfer doesn't ship one.
Auto-flag of factual drift in your content + auto-patch + brand-safety guardrails for AI-engine consumption. Outside Surfer's scope.
Vectory ships with a real engineer reachable on Telegram. Surfer's support is good but ticket-based.
