Semrush is excellent for Google SEO. But for AI search visibility — ChatGPT, Perplexity, Gemini — you need a purpose-built AEO tool. Here is why.
This is not an attack on Semrush. It is one of the best SEO tools ever built, and it remains essential for any team doing serious Google SEO. Backlink analysis, keyword research, technical site auditing, rank tracking — Semrush does these better than almost anything else on the market.
The point of this article is simpler: Semrush was built for Google. AI search is a different channel. And if you are using your Semrush subscription as your entire search visibility strategy in 2026, you have a growing blind spot.
Semrush's core strengths are genuine and hard to match:
If you are running a serious Google SEO program, these capabilities are non-negotiable. Nothing changes there.
AI search requires fundamentally different measurement and optimization capabilities.
Brand mention tracking in AI-generated answers — Semrush tracks keyword rankings. AI search requires tracking whether your brand *name* appears in AI-generated answers — not rankings, but mentions in synthesized responses. These are different data points requiring different infrastructure.
[MentionShare score](/features/mentionshare) across 9 AI engines — Your AI visibility is not a single number — it varies by engine. You might have 45% MentionShare on Perplexity but 8% on ChatGPT. Understanding per-engine breakdown requires monitoring each AI engine separately, which Semrush is not designed to do.
Competitor share of voice in AI responses — Knowing that ChatGPT recommends your competitor instead of you, for which prompts, and with what frequency, requires direct AI engine monitoring. Semrush's competitor analysis is excellent for Google; it does not extend to AI-generated answer surfaces.
[Fix Generator](/features/fix-generator) for AI-specific content — The content you publish to improve AI visibility (FAQ blocks, answer paragraphs, targeted JSON-LD schema) requires understanding which specific prompts your brand is missing and generating content for those exact queries. This is a purpose-built capability that traditional SEO tools do not have.
AI SEO page scoring — Scoring each page on FAQPage schema, entity clarity, answer-formatted content, and AI crawler accessibility is a different audit than checking for broken links and page speed.
Semrush has launched several AI-related features, including AI writing assistance and some AI visibility tracking capabilities. These are genuinely useful additions.
However, they are built on Semrush's existing keyword and position-tracking infrastructure, which is designed for Google's ranking algorithm. This architecture produces useful directional data — helping you understand which keywords are trending in AI-related contexts — but it is not the same as directly monitoring AI engine brand mentions.
Think of it this way: Semrush can tell you that the keyword "best AEO tool" is growing in search volume. A purpose-built AEO tool can tell you that ChatGPT recommends your competitor for that query 60% of the time, Perplexity recommends you 30% of the time, and Gemini has never mentioned you. The second data type directly informs your content and positioning strategy in a way the first cannot.
