This handles IndexNow protocol integration so you can notify Bing and Yandex when you publish or update pages instead of waiting for them to crawl naturally. You get it set up once with an API key and verification file, then submit URLs individually or in batches, ideally hooked into your deploy pipeline. The skill emphasizes treating your sitemap config as the single source of truth for URLs rather than maintaining separate hardcoded lists that drift out of sync. Google doesn't support IndexNow, so this is really a Bing play. If you're doing technical SEO work and care about Bing indexing speed, it's a straightforward win with minimal overhead.
