Instly Scout vs Semrush
Semrush is the biggest SEO platform in the world and now sells an AI Visibility toolkit on top of it; Instly Scout is a two-instrument measure-and-fix service for one website at a time. We compared the two on what each company's own homepage passes, and on how often the four main AI engines named each one when asked which AI visibility tools to use. Semrush wins the naming test today, and ties us on the technical one. We publish that.
Website check, 13 technical checks, 5 Oct 2026
Both homepages pass all 13 checks. Semrush is one of four sites in our 20-vendor benchmark to do so.
AI answer check, 20 answers, 29 Sep 2026
semrush.com was read 6 times across the 20 answers, third most of any domain. Instly Scout was not named once.
Different products for different buyers.
Taken from each company's own homepage on 6 Oct 2026, quoted rather than paraphrased where it matters.
Semrush
Headline: "Be found everywhere search happens". The homepage sells "Get found in search and AI answers", an "AI Visibility" solution, a free "AI Visibility Checker", an "AI Visibility Index" and "317M+ LLM prompts". Twelve customer logos are shown, including Shopify, Booking.com, Samsung, Netflix and Airbnb.
What it is for: an SEO team that already lives in Semrush and wants AI answer tracking in the same dashboard, from solo operators to enterprise.
No price on the homepage; plans on a separate pricing page.
Instly Scout
Two instruments: a website check of 13 weighted technical checks on the homepage, free and instant, and an AI answer check that asks five of your buyers' questions to ChatGPT, Gemini, Perplexity and Claude and records which brands each answer names, cites and ranks. Then the work: content written and blockers fixed, each change approved by you, re-measured with the same questions, with the dated before and after published.
What it is for: a business with one website that wants to be the answer AI gives, and wants proof it happened.
USD 500 a month, three-month term, built and run by one person in Bangkok.
What each homepage passes and fails.

Zero-weight findings: instlyscout.com named its brand only in the browser tab on 5 Oct (fixed the same day; left as measured). Semrush: 18 of 60 sampled sitemap pages have no internal link, including /llms.txt itself. Every AI crawler we test returned 200 on both sites.
Who the engines named, and what they read.
Five buyer questions about AI visibility tools, asked to ChatGPT, Gemini, Perplexity and Claude on 29 Sep 2026, 04:41 UTC. The full table of all 13 tools named is on the league table.
Semrush
Joint first with Profound. semrush.com was read 6 times across the 20 answers. The engines quoted its own AI visibility pages and its blog.
Instly Scout
Passing all 13 technical checks did not get us named once. The engines answered these questions from independent round-ups and from vendors' own comparison pages, and we were in neither on 29 Sep. This page is part of fixing that. Next reading: after 28 Oct 2026, published whichever way it lands.
Pick by what you will do with the data.
Semrush, if
You already pay for Semrush, your team works in it daily, and you want AI answer tracking alongside rankings rather than a separate service that also does the work.
Instly Scout, if
You have one website, you want to know in plain counts whether AI names you for the questions your buyers ask, and you want someone to do the work and show you the dated before and after. Start with the free website check.
Method: website check is Scout's 13-check instrument, run on the homepage over HTTP on 5 Oct 2026; the per-check record is in the dated benchmark behind this article. Named counts are from Scout's AI answer check of 29 Sep 2026. Product descriptions are quoted from semrush.com on 6 Oct 2026 and will be out of date when they change theirs. Nothing here is an opinion about which tool is better; it is two readings and who each is built for. Other comparisons: vs Profound, vs Scrunch AI, vs Peec AI, vs Otterly AI.
