Prerender Buddy: SEO & AI Crawler Checker

Description

Check crawler-readable HTML for JavaScript SEO and technical AEO, GEO, and AI search readiness. Prerender Buddy is a crawler-readability checker for JavaScript websites. It helps you identify when search engines and AI crawlers may receive a thin application shell instead of the meaningful content visitors see after JavaScript runs. Crawler-readable HTML is a technical foundation for JavaScript SEO, answer engine optimization (AEO), generative engine optimization (GEO), and AI search readiness. This extension checks that foundation without claiming to be a complete SEO, AEO, or GEO platform. Open the extension on any public HTTP or HTTPS page to run a focused crawler- style check. The side panel returns a readability score, groups passed checks and problems, and shows the most important technical signals without turning the result into a generic SEO audit. Use it to review: - Readable content available to crawler-style requests - Raw HTML and JavaScript-rendered content signals - Page title, description, headings, and other metadata - robots.txt and crawler-access restrictions - Thin-content, response, rendering, and timeout problems - A score badge for the latest checked page Prerender Buddy is designed for founders, developers, agencies, SEO consultants, and teams working with React, Vite, Vue, no-code, or AI-built websites. It is especially useful when a site looks complete in a browser but you need to confirm what crawlers can actually retrieve. When a problem is found, you can continue to the Prerender Buddy web application to save the site, review setup options, and verify crawler-readable HTML after connecting it. Privacy and permissions: - The extension checks only the active public page when you open it - The active page URL is sent to the Prerender Buddy API for analysis - It does not read passwords, form fields, cookies, or private browsing history - It does not modify the page you are viewing - It does not sell user data Important limitations: Prerender Buddy checks technical crawler readability for search and AI discovery. It does not guarantee crawling, indexing, search rankings, AI citations, recommendations, traffic, or revenue. Content quality, authority, links, structured data, and the rest of SEO, AEO, and GEO still matter.
