Auto-Indexing 30 Sites with IndexNow and Google Indexing API
This technical article details the development of 'Indexing-Astroworld,' a lightweight TypeScript service designed to accelerate search engine indexing for a network of 30 websites. The author addresses the latency issues inherent in traditional sitemap discovery, where Google and Bing can take days or weeks to index new content. The solution employs a systemd timer to trigger a diff worker every six hours, which fetches sitemaps, compares them against a local snapshot to identify new or changed URLs, and immediately submits them via two distinct protocols. The article clarifies the differences between IndexNow, an open protocol supported by Bing, Yandex, and others, and the Google Indexing API, which requires authentication and has daily quotas. The architecture is notably simple, avoiding databases or queues in favor of disk-based state management. This approach ensures rapid visibility for time-sensitive content across multiple search engines, demonstrating a practical application of modern indexing APIs for multi-site management.
