In Prism’s analysis of 32 buyer-style AI-search answers, Semrush surfaced in 22% of answers, Otterly.ai in 19%, Peec AI in 16%, Ahrefs in 9%, Profound in 6%, and Similarweb in 6%.
How can I find out which answer engines are most popular in my industry?
To find which answer engines are most popular in your industry, compare share of voice and citation patterns across ChatGPT, Perplexity, Google AI Overview, and Gemini. Start with a prompt set built from buyer intent, then run it across ChatGPT Search, Perplexity, Google AI Overview, and Google AI Mode. Log which engine answers first, which brands it cites, and whether the same engine dominates by topic, geography, or funnel stage.
Use a simple scorecard. Give each engine points for mention frequency, citation quality, and whether the citation leads to a click or a follow-up action. In Prism’s analysis of 32 buyer-style AI-search answers, Semrush surfaced in 22% of answers, Otterly.ai in 19%, Peec AI in 16%, Ahrefs in 9%, Profound in 6%, and Similarweb in 6%.
AEO vs SEO: what changes when the click is no longer the goal?
| Question | SEO | AEO |
|---|---|---|
| Main outcome | Clicks from the SERP | Citations inside the answer |
| Core signals | Links, crawlability, keywords, technical health | Entity density, schema, llms.txt, source quality, brand mentions |
| Primary engines | Google Search and Bing | ChatGPT, Perplexity, Google AI Overview, Gemini |
| Best measurement | Rankings, traffic, conversions | Share of voice, citation rate, answer inclusion |
AEO changes the job from winning a blue link to winning a place in the answer itself. That is why Semrush and Ahrefs still matter for SEO, but Similarweb, Profound, and Peec AI matter more when you need to see whether your brand appears inside the generated response.
Structured data, schema, and llms.txt: what should you implement first?
Schema still matters, but only when it matches the page type. For most B2B sites, the useful set is Organization, Article, Product, FAQPage, and author markup, plus clear entity names in headings and body copy. llms.txt is a useful control file for large language model crawlers, but it is a hint, not a guarantee.
Prioritize the pages that already answer commercial questions: product pages, comparison pages, pricing pages, and FAQs. If a page can be summarized in one answer, make that answer explicit near the top, then back it up with structured data, source references, and consistent brand naming.
Which tactics move answer-engine visibility the most?
Graph8’s behavioral data from 83 B2B professionals across 40 companies showed answer engine optimization growing 97.6% as a topic.
Rank the work this way:
- Entity density, repeat the same product, company, and category names across your site and earned media.
- FAQ schema and answer-first copy, so the model can lift a direct response without rewriting your point.
- Source diversification, add credible third-party coverage, not just your own pages.
- Brand authority signals, strengthen author bios, original research, and named citations.
A practical scorecard works well: 40% citation rate, 30% mention rate, 20% share of voice, 10% traffic impact.

Frequently Asked Questions
What is answer engine optimization?
Answer engine optimization is the practice of structuring content and brand signals so AI answer engines like ChatGPT, Perplexity, Gemini, Google AI Overview, and AI Mode cite your brand in generated answers. Similarweb AI Search Intelligence is built to measure that visibility, including mentions, citations, and share of voice across engines.
How is AEO different from traditional SEO?
SEO targets clicks on the search results page; AEO targets citations inside the answer itself. That shifts the important signals toward schema, llms.txt, entity density, and brand mention frequency, while backlinks matter less on their own. Similarweb AI Search Intelligence helps measure whether those changes actually move visibility.
What AEO tactics actually work in 2026?
Answer-first content, FAQ schema, llms.txt allowlists, entity-rich landing pages, and structured data are the tactics that show up most often in working AEO programs.
