IndexNow is a free, open-source protocol empowering website owners with unprecedented control over how quickly their content is discovered and displayed in search results—giving consumers access to the most current information at the time of search.

Figures suggest that Google has 1 billion daily active users compared to Bing's 100 million. Yet whilst Google continues to dominate the global market in 2024 with a 90.01% market share, challenger search engines like Microsoft's Bing have pushed to eat up a portion of this share in recent years.

IndexNow offers a powerful solution for webmasters to ensure their added, updated, and deleted content is promptly indexed by search engines. Practically any website with content can benefit from IndexNow, as it helps maintain up-to-date information in search results, enhancing visibility, traffic, and user engagement.

The functionality of both search engines might be similar; however, Google offers more core features overall. The contrast also extends to their index size and crawling, with Google boasting an index of hundreds of billions of web pages. Bing is estimated to have an index of between 8 to 14 billion web pages.
