Show HN: What GPTBot sees before your React app hydrates (botscore.io)

A new tool called BotScore aims to address the significant issue of "DOM drift" in single-page applications (SPAs) like those built with React, where AI crawlers, such as GPTBot, may not fully render the content after JavaScript executes. Developers often encounter a situation where the initial HTML response contains minimal elements, like an empty `<div id="root"></div>`, causing vital SEO content to be invisible to non-JavaScript-aware agents. This discrepancy can have SEO implications, as critical information intended for both users and AI agents may not be effectively indexed. BotScore provides a browser-based audit tool that compares the initial HTML served to bots with the live DOM after hydration, identifying any missing vital elements like headings and main content. It operates locally on the developer's machine, assessing 27 criteria to determine if key components are accessible to crawlers. By alerting developers to issues such as missing `<h1>` tags in the raw HTML, BotScore ensures that web applications can be optimized for machine readability, enhancing visibility in search engine results and ultimately supporting better user experiences.
