See what AI crawlers can't read on your page | then fix it.

BotScore is a browser extension that audits the page in your active tab for bot and LLM readability. 27 deterministic rules across five categories score a 0–100 GEO score, list issues with fix guidance, and let you copy an Agent Brief in Markdown. Runs locally; nothing is uploaded.

GEO is the practice of making pages legible to AI crawlers and answer engines—not only traditional search rankings. BotScore measures GEO with rules for discoverability (llms.txt, llms-full.txt, robots, sitemap, canonical), machine-readable HTML and DOM drift, structured data, accessibility signals bots rely on, and classic SEO metadata.

BotScore runs 27 deterministic rules across five categories. Your GEO score starts at 100 and subtracts rule penalties (capped at 100 points lost). Category bars show per-category deductions. The panel lists which rules passed, warned, or failed so you fix the highest-impact issues first.

No. Audits execute in the extension on your device. BotScore does not send your HTML or audit results to our servers. The extension may fetch the page URL, initial HTML, robots.txt, llms.txt, and llms-full.txt from the site you are viewing—same origin only. Pro license activation validates your key with our license server; no page content is sent.

On Chrome, BotScore asks once before your first audit. Site access lets the extension inject the audit script and read same-origin files (initial HTML, robots.txt, llms.txt, llms-full.txt) only on pages you audit—not in the background. Nothing is sent to BotScore servers. Firefox does not show this prompt; the permission is included at install.

Firefox shows “Read and modify data on all websites” at install because the extension declares host access in its manifest. BotScore only uses that access when you run an audit on a tab you opened | to read the page DOM and fetch same-origin files (initial HTML, robots.txt, llms.txt, llms-full.txt). It does not run in the background or scan sites you never audit. Nothing is sent to BotScore servers. Chrome asks for the same access once, before your first audit, instead of at install.

No. BotScore does not collect telemetry, analytics, or browsing history. Audits run entirely in your browser; page HTML and audit results are not sent to BotScore servers. License validation sends only your Lemon Squeezy license key and a device instance id to our validation endpoint | not page content.

Chrome and Firefox (Manifest V3). Chromium builds use the side panel; Firefox uses the sidebar action. Install links are on this page and in the install dialog.

Any normal https:// web page you can open in a tab. Browser internal pages (chrome://, the extension UI, etc.) cannot be audited.

Lighthouse scores performance and some SEO basics for humans in DevTools. Traditional SEO suites focus on rankings, backlinks, and campaigns. BotScore is built for agent-readability: llms.txt, llms-full.txt, AI bot robots rules, semantic structure, JSON-LD, DOM drift, accessible names, and how crawlers see your initial HTML.

Traditional tools score your post-hydration DOM. BotScore compares your raw HTML to your hydrated DOM to tell you exactly what AI crawlers are missing.
