Answer Engine Optimization is a free tool focused on AI answer engine visibility checks. Its core goal is to measure the extent to which a brand is named and cited in answers generated by AI assistants, rather than link rankings in traditional search results.
Purpose This tool is used to perform an "answer engine optimization" check, helping users understand their brand's visibility in AI answers. Users only need to enter a domain to receive a visibility report across multiple mainstream AI answer engines.
Main Capabilities The tool supports checking six engines at the same time: ChatGPT, Gemini, Copilot, Perplexity, Claude, and Google AI Overviews. The report includes: whether the brand is mentioned in the answer text, mention trends, and which sources the engines cited when generating answers. The report is divided into eight sections, with data from Ahrefs Brand Radar, which records real AI responses so trends can be compared month by month. The tool also provides a free check with no account required.
How to Use Users visit https://answerengineoptimization.pro/，输入域名，即可运行免费的 AI visibility check. The tool reads the brand mentions, trends, and citation sources across six engines and generates a report. In addition, the page also provides an eight-item checklist that does not depend on the tool, to be carried out in order: list the twenty questions buyers will ask before making a decision; run five of those questions in each of the six engines and record who is mentioned; place a two-sentence direct answer at the top of each page; keep the brand name, category, and description consistent across the website, materials, and listings; ensure structured data matches the visible content on the page; check the roundups, directories, and review sites already cited in the category; provide appropriate answers in relevant community posts; update pricing, comparison, and year-labeled pages.
Use Cases Suitable for marketers, SEO practitioners, brands, and content strategists who want to understand their brand's exposure in AI answers. It is especially suitable for teams that find a mismatch between traditional SEO rankings and AI answer visibility, to determine which topics, sources, and community posts are worth investing in, and whether a dedicated person is needed for AI visibility.
Limitations The material does not provide a specific pricing model, price, platform support scope, or performance guarantees. The tool currently only provides a free check, and other features and service scope have not yet been provided. Regarding llms.txt, the material points out that it is a community proposal rather than a ranking requirement, and Google currently says it ignores llms.txt in search visibility, so it can be regarded as optional housekeeping work.
