AEO Villa
An Answer Engine Optimization SaaS that audits websites for AI search visibility, scores them from 0 to 100, tracks whether AI answers cite a brand, and turns every finding into a prioritized fix queue.

The Challenge
Search is moving from result pages to AI answers, and brands had no way to tell whether answer engines could crawl, understand, and cite their sites. Traditional SEO tools ignore AI crawler rules, llms.txt, entity data, and citations, so the product had to audit a whole site against AEO specific checks, measure real citations in AI answers that change from one run to the next, and turn hundreds of findings into a short list of fixes a marketer could act on and measure.
The Approach
Built a Next.js 16 App Router platform on MongoDB and Mongoose with every query scoped to a workspace and brand, enforced by an automated route policy check. A single page scan fetches through an SSRF safe client, parses the page with Cheerio, and blends eight weighted categories (schema, metadata, AI readiness, clarity, trust, EEAT, headings, and performance) into a 0 to 100 score. A multi page crawler runs page scans and Core Web Vitals checks in parallel through the PageSpeed Insights API, then normalises results against a catalog of 89 issue types with a per bot AI crawler access matrix. Citation tracking runs each prompt several times against Gemini with Google Search grounding and extracts the cited domains for share of voice. One cron entrypoint behind a lease lock drives rescans, citation checks, digests, and billing reconciliation, Stripe handles four plans with idempotent webhooks, and the app runs on a Dokploy managed VPS with Sentry monitoring.
