Scrunch and Semrush take different approaches to AI visibility

HubSpot’s marketing team has compared Scrunch and Semrush as part of its testing of answer engine optimization tools. Its central distinction is that Scrunch focuses on tracking brand visibility in AI-generated answers, while Semrush includes AI visibility measurement within its broader SEO suite.

Answer engine optimization, or AEO, aims to improve how often AI services mention a brand or cite its website, as well as the accuracy of those mentions. That makes the measurement task different from conventional search-rank tracking. An AI engine may produce a single written answer with several cited sources, or with no citations, rather than a page of search results.

For marketers, the comparison is therefore about more than whether a product tracks keywords. HubSpot frames visibility in terms of what appears in the answer itself: whether the brand is named and whether its website is cited. A measurement tool must examine those responses to assess that visibility, rather than relying solely on a rankings table.

HubSpot organizes its comparison around four areas: coverage of answer engines, citation tracking and auditability, reporting and export, and integration with existing workflows. It presents each area as part of the decision, rather than naming one product the best choice for every team. The appropriate option depends on what a team needs from an AEO tool and how that work fits alongside its existing SEO activity.

The distinction between a dedicated tool and a feature within an SEO suite is important to the comparison. Teams considering Scrunch can evaluate it as a product built around monitoring appearances in AI answers. Those considering Semrush can assess its AI visibility capabilities in the context of the SEO suite their teams may already use. HubSpot also recommends validating AEO data during free trials before making a commitment.

What this means for marketers

Before choosing a tool, teams can use a trial to check how its data supports their own assessment of brand mentions and website citations. They should also review the answer engines covered, whether citations can be audited, how reports and exports work, and how the product fits their workflow. The choice is between a dedicated AEO approach and AI visibility tracking within a wider SEO suite—not simply between two ranking tools.
