About

一鍵檢測網頁的 AEO（AI 搜尋優化）指標：llms.txt、AI 爬蟲權限、sitemap、結構化資料、Meta 標籤與內容結構。

Let's AEO 幫你快速檢查目前網頁在 AI 搜尋時代的優化程度（AEO，AI Engine Optimization）。打開擴充功能，立即取得六項關鍵指標的即時評分，不需要登入、不需要設定。

【檢測項目】

● llms.txt
偵測網站根目錄是否提供 llms.txt（以及 llms-full.txt），這是協助 AI 引擎理解網站內容的新興標準。內建 soft-404 防護，避免把 SPA 萬用路由誤判為有效檔案。

● AI 爬蟲權限
解析 robots.txt，判定主流 AI 爬蟲是否被允許存取你的網站。若全部被封鎖，會明確警告網站對 AI 引擎不可見。

● Sitemap
檢查 robots.txt 是否宣告 Sitemap，或探測 /sitemap.xml 是否存在。

● 結構化資料
掃描頁面中的 application/ld+json，統計區塊數量與 JSON 有效性，並列出偵測到的 @type。對 AEO 特別有價值的類型（如 FAQPage、HowTo 等）會以綠色標示。

● Meta 標籤
檢查 title、meta description、canonical、html lang、Open Graph，並偵測會讓頁面從索引中消失的 noindex / noai。

● 內容結構
檢查是否單一 h1、標題層級有無跳級、是否使用 main / article 語意地標 —— 這些都影響 AI 抽取內容的準確度。

【特色】

✓ 一鍵檢測，打開即跑，無需註冊或設定
✓ 介面支援正體中文、English、日本語即時切換
✓ 完全在本機運作，不蒐集、不上傳任何個人資料
✓ 採最小權限設計，僅在你點擊時讀取當前分頁

適合內容創作者、SEO／AEO 行銷人員、網站開發者，快速體檢網站對 AI 搜尋引擎的友善程度。

One-click audit of a page's AEO signals: llms.txt, AI crawler access, sitemap, structured data, meta tags & content structure.

Let's AEO gives you an instant check on how well the current page is optimized for the AI-search era (AEO — AI Engine Optimization). Open the extension and get a real-time scorecard across six key signals. No sign-up, no setup.

【What it checks】

● llms.txt
Detects whether the site root serves llms.txt (and llms-full.txt), an emerging standard that helps AI engines understand your content. Includes a soft-404 guard so SPA catch-all routes aren't mistaken for a valid file.

● AI crawler access
Parses robots.txt and reports whether major AI crawlers are allowed to access your site. If all are blocked, it clearly warns that the site is invisible to AI engines.

● Sitemap
Checks for a Sitemap directive in robots.txt, or probes /sitemap.xml.

● Structured data
Scans application/ld+json on the page, counts blocks and JSON validity, and lists the detected @type values. Types that are especially valuable for AEO (such as FAQPage and HowTo) are highlighted.

● Meta tags
Audits title, meta description, canonical, html lang, and Open Graph — and flags noindex / noai directives that remove the page from indexing.

● Content structure
Checks for a single h1, skipped heading levels, and the presence of main / article landmarks — all of which affect how accurately AI extracts your content.

【Highlights】

✓ One click — opens and runs instantly, no account or configuration
✓ UI available in Traditional Chinese, English, and Japanese, switchable on the fly
✓ Runs entirely on-device — collects and uploads no personal data
✓ Minimal permissions — reads the active tab only when you click

Ideal for content creators, SEO/AEO marketers, and web developers who want a quick health check on how AI-search-friendly a site is.
