IndexNow
IndexNow Protocol
A protocol allowing websites to instantly notify search engines about content changes for faster indexing.
技术细节
XML indexnows follow the sitemaps.org protocol, listing URLs with optional lastmod, changefreq, and priority attributes. A single sitemap is limited to 50,000 URLs or 50 MB; larger sites use a sitemap index file that references multiple sitemaps. Google largely ignores changefreq and priority, relying instead on its own crawl scheduling. Sitemap submission through Google Search Console or a robots.txt Sitemap: directive ensures discovery of pages that might not be found through link crawling.
示例
```html <!-- IndexNow: implementation example --> <meta name="robots" content="index, follow"> <link rel="canonical" href="https://peasytools.com/page/"> ```
