For years, the Sitemaps protocol had a limit defined by the sitemaps.org that each sitemap file may only contain upto 50,000 URLs, and must not exceed a 10MB (10,485,760 bytes) file size. Today, Bing is increasing the size limit of Sitemaps file to address evolving webmaster needs.

To this end, the sitemaps file and index size limit is raised from 10 MB to 50MB (52,428,800 bytes). Bing notes, that they "occasionally encounter sitemaps exceeding this limit. Most often the cause lies with 'very long URLs' or 'attributes listing long extra URLs (as alternate language URLs, Image URLs, etc)," which inflates the size of the sitemap file, explains bing.

This update to file size change is now reflected in the sitemap protocols, and it only "impacts the file size." Each sitemap file and index file "still cannot exceed the maximum of 50,000 URLs (<loc> attributes)."

With this change, webmasters can still gzip compress their Sitemap files, however they need to ensure that "each sitemap once uncompressed must still be no larger than 50MB," bing adds.

In a releated news, new additions to Bing Search APIs announced today to help developers enrich apps and experiences, such as "video previews, license filters, retailer lists and recipes."

One collection includes web, image, video and news search, embedding the knowledge and intelligence of web search directly into experiences and apps. With the Bing Video Search API, developers can add advanced video search features, including video previews, trending video results, filters for free or paid options and other useful metadata, such as creator, encoding format, video length and view count.

This collection of APIs is a great starting point for developers creating mobile apps. They are REST APIs that follow the latest structured data standards (Schema.org, JSON-LD), making them easy for users to find relevant results from billions of webpages, images, videos and news with one call and a few lines of code.

Here is a brief description of what each of these APIs are meant to be:

  • Bing Web Search API provide search results for billions of web pages, images, videos and news with a single API call including most commonly clicked links on the destination website. Other features include: adult intent signal to help customize safe search level of the results, filtered answers, pagination, bolding, query alteration and spell suggestions where commonly misspelled terms are automatically corrected.
  • Bing Image Search API offers powerful image search capabilities and can provide results that span from a narrow search topic to trending images to visually similar images and more. also, extra filters and parameters such as size, license, style, freshness, and color are available.
    • Image insights allow you to get deeper information about a specific image based on machine learning and entity recognition.
    • Safe search is another powerful feature that allows you to adjust image insight settings to help filter out inappropriate search results, such as explicit adult and racy content.
    • Other new features such as merchants and recipes exposes list of retailers that sell a given product in an image. With images of food, we have tagged a number of different sources where there is a recipe with instructions on how to make that specific item.
  • Bing Video Search API lets you add advanced video search features, including video previews, trending video results, filters for free or paid options and other useful metadata, such as creator, encoding format, video length and view count.

    Motion thumbnails (i.e., video preview) are a new addition that help drive engagement.

  • Bing News Search API help users find relevant news results by topic, geographical location and rich article metadata by category/market and trending news (top results in the relevant topic).
