SEOTesting's feed is mostly comparison content, with one real shipped feature: an LLM-referral clicks report.
Most crawled entries are SEOTesting's content-marketing blog — competitor comparisons, tool roundups, and SEO testing guides. One entry, however, announces a genuine product addition: a new report showing how many clicks LLMs like ChatGPT and Gemini send to a site. So the feed is largely editorial, with an occasional real release note about measuring AI-search referral traffic.
Surfer rebuilds itself around AI search, betting content has to win citations, not just rankings.
Surfer is repositioning from a Google-ranking optimization tool to one that optimizes for both classic SEO and AI search visibility — getting content cited inside ChatGPT, Perplexity, and AI Overviews. Recent releases fold AI-search scoring directly into the existing Content Score and Auto-Optimize flow, so the dual target is one workflow rather than a separate product. A redesigned workspace and an expanded API round out the platform work underneath.

The observable product thread is small but pointed: SEOTesting is building reporting around AI-search and LLM referral traffic, matching where the wider SEO category is moving. The surrounding comparison content positions it against Ahrefs and Semrush. Expect more measurement features tied to AI search if that one release is indicative.
The next moves may extend AI-search and LLM-referral reporting, given that thread and the 'rank in AI search' content. The comparison posts are marketing, not a roadmap signal.
Surfer is repositioning from a Google-ranking optimization tool to one that optimizes for both classic SEO and AI search visibility — getting content cited inside ChatGPT, Perplexity, and AI Overviews. Recent releases fold AI-search scoring directly into the existing Content Score and Auto-Optimize flow, so the dual target is one workflow rather than a separate product. A redesigned workspace and an expanded API round out the platform work underneath.
The throughline is AI search as the new battleground: a unified score across SEO and AI citations, intro-writing guidelines tuned to whether an AI will cite you, and auto-linking that makes first drafts publish-ready. The new API explicitly names Surfer MCP and an agentic 'Surfy', pointing toward Surfer becoming a programmatic and agent-driven layer rather than only a manual editor.
Expect the MCP and agentic Surfy foundations to ship as usable products next, and for more of the editor's manual optimization to move under Auto-Optimize. How deep the agentic automation goes versus staying assistive is the open question in these entries.
