If you've been asking whether Semrush is enough for generative engine optimization — or whether you need a dedicated AI search tracking tool — you're asking exactly the right question. The honest answer: Semrush is a powerful SEO platform that has added some AI Overview monitoring, but it was built to measure search engine rankings, not AI recommendation behavior. Those are fundamentally different problems, and the gap between them is where brands are quietly losing ground every day.
This page breaks down exactly what Semrush covers, where it stops, and what a dedicated AI visibility platform like AIsubtext measures that Semrush cannot.
To be fair to Semrush: it is an excellent tool for what it was designed to do. Its keyword research, content audit, backlink analysis, and position tracking features are industry-standard. In recent product cycles, Semrush has added monitoring for Google AI Overviews — the AI-generated summaries that appear at the top of some Google search results pages.
That addition is genuinely useful if your primary concern is whether your content appears in Google's on-SERP AI summaries. But Google AI Overviews are one narrow slice of the generative AI landscape. They are not the same as:
These are the moments where AI is already picking winners — and Semrush has no visibility into them.
Traditional SEO tools, including Semrush, are built around a core metric: where does your page rank for a given keyword? That model assumes a search engine returns a list of links and a human chooses one.
Generative AI engines don't work that way. When a buyer asks ChatGPT or Claude for a vendor recommendation, the model synthesizes an answer and names specific brands. There is no rank position 1 through 10. There is only: were you named, or weren't you?
AIsubtext was built around this reality. The platform measures your Recommendation Share — the percentage of relevant AI queries in your category where an AI engine names and recommends your brand — across ChatGPT, Claude, Gemini, and Perplexity simultaneously. That number is what determines whether AI is sending buyers your way or to a competitor.
Semrush does not measure Recommendation Share. It cannot, because its architecture is built on crawling search engine indexes, not querying large language models at scale.

The brands that will dominate AI-driven buyer journeys over the next three years are not necessarily the ones with the best SEO. They are the ones that understand how AI engines perceive, describe, and recommend them — and actively manage that signal.
Consider what Semrush cannot tell you:
These are not hypothetical future concerns. AI engines are already the first stop for millions of B2B buyers researching vendors. If you don't know your Recommendation Share, you don't know whether AI is working for you or against you.
This is not an argument to cancel your Semrush subscription. If you run content marketing, manage organic search, or care about Google rankings, Semrush remains a strong investment. The point is that Semrush and AIsubtext solve different problems.
Semrush answers: How does my content rank in search engines?
AIsubtext answers: How often do AI engines recommend my brand — and what do I do to capture more?
As buyer research behavior shifts toward conversational AI queries, the second question is becoming the more commercially consequential one. AIsubtext exists specifically to answer it — with measurement across the four major LLM platforms, competitive share of voice data, sentiment diagnostics, and a concrete playbook for improving your position.
You can run a free audit in approximately 10 seconds, with no credit card required, to see your current Recommendation Share and where you stand relative to competitors in your category.

No. Semrush's AI-related features are focused on Google AI Overviews — the summaries Google generates within its own search results. Semrush does not query ChatGPT, Claude, Perplexity, or Gemini, and does not measure how often or how favorably those platforms recommend your brand. If your buyers are using any of those tools to research vendors — and increasingly they are — Semrush has no visibility into that behavior.
Recommendation Share is the percentage of relevant AI queries in your category where an AI engine names and recommends your brand. AIsubtext measures this number across ChatGPT, Claude, Gemini, and Perplexity. It matters because when a buyer asks an AI engine for a vendor recommendation, there is no ranked list — the AI names specific brands. If your Recommendation Share is low, AI is actively directing buyers to competitors, often without you knowing it.
Yes, and for most marketing teams this is the right approach. Semrush handles traditional SEO, content auditing, and Google AI Overview monitoring. AIsubtext handles LLM-native measurement: Recommendation Share, AI brand sentiment, competitor share of voice in generative answers, and the playbook to improve your position across the major AI engines. They address different channels and different buyer touchpoints.
AIsubtext offers a free brand audit that returns results in approximately 10 seconds with no credit card required. The audit shows you how AI engines are currently recommending (or not recommending) your brand and gives you an initial read on where you stand relative to competitors in your category.
