Semrush has launched a Brand Visibility Framework at Adobe Summit, introducing Agentic Search Optimisation as a new discipline for measuring brand presence across AI-generated answers, traditional search, and autonomous AI agents. The framework uses a database of over 213 million large language model prompts to show brands how they are being discussed, recommended, or ignored inside systems where no human ever clicks a link. This comes as organic click-through rates have dropped 61% on queries with AI Overviews, and Semrush’s own AI product revenue has grown 850% to $38 million ARR. The company is in the process of being acquired by Adobe for $1.9 billion, a deal announced in November 2025 and expected to close in the first half of this year. The research accompanying the framework also highlighted a disconnect between investment and visibility, with 94% of brands investing heavily in traditional SEO, while 62% are "technically invisible" to generative AI models.
