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.
Kit is becoming a creator-business platform — audience data, native landing pages, and AI access.
Kit is pushing past email sending into the broader business of running a creator audience. Recent releases include Subscriber Signals (demographic and professional data on your list), a rebuilt native landing-page builder, a Kit MCP for AI tools, plus searchability and deliverability fixes. The email core is steady; the value proposition is expanding around it.

So the feed is largely editorial, with an occasional real release note about measuring AI-search referral traffic.
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.

The email core is steady; the value proposition is expanding around it.
The directional moves are about owning more of the creator stack: audience intelligence and sponsorship tooling (Subscriber Signals), displacing third-party page builders (rebuilt landing pages), and an AI/MCP interface for managing it all. Underneath, a run of search and quality-of-life fixes — searchable rules and automations, name search, typo-catching forms — keeps the daily tooling sharp. Kit wants to be where a creator's business lives, not just where their newsletter sends.
Subscriber Signals graduating from early access is the likely next beat, probably tied to monetization features like the sponsorship deck; expect continued MCP and app-store expansion alongside.
