SAG Tool is a website audit platform that checks any page against SEO, AEO, and GEO criteria — the three disciplines that now determine search visibility. We built it because no existing tool covered all three.
S — SEO. Search Engine Optimization. The foundation — technical signals, content structure, and authority that determine Google rankings.
A — AEO. Answer Engine Optimization. Structuring content so ChatGPT, Perplexity, and Google AI Overviews extract and cite your page as the answer to user queries.
G — GEO. Generative Engine Optimization. Building the entity authority and credibility signals AI systems use when deciding which sources to trust and cite.
We were auditing websites in early 2026 and kept running into the same problem — pages that scored well on traditional SEO tools were scoring zero on AI visibility signals. FAQPage schema missing. No question H2s. No external citations. No Organization schema. No Article schema. The tools weren't checking for any of it.
We built SAG Tool to give website owners, SEO professionals, and developers the complete picture. One audit. Three disciplines. A composite grade from A to F. No guessing about where you stand.
The free tier gives you three audits with no account required. The paid tiers progressively reveal more — why each rule failed, where on the page, and the exact HTML to replace it with.
Title tags, canonical URLs, heading structure, HTTPS, Core Web Vitals, internal links, image alt text, word count, and content depth. The foundation every page needs.
Question H2s, answer blocks, FAQPage schema, comparison tables, step lists, and definition sentences — the signals AI engines use to extract and cite your content.
Organization schema, Article schema, external citations, statistics, named authorship, content freshness, and AI bot access — the credibility signals AI systems trust.
Website owners who want to know if their pages are visible to AI search engines — not just Google.
SEO professionals who need a tool that checks AEO and GEO signals alongside traditional SEO criteria in a single report.
Developers who want line numbers and replacement HTML — not just a list of problems to interpret.
Agencies who need downloadable white-label reports and team seats to deliver AI search audits to clients.
