Bing and Google to Increase Sitemaps to 50 MB

Bing and Google jointly announced that they are increasing the size limit of sitemaps to 50 MB from 10 MB it is currently limited to.  The change only impacts the sitemap file size. It does not affect the restriction on the amount of URLs that can be contained in a sitemap, which is currently confined to 50,000.
In the announcement , Microsoft stated the following:
“While most sitemaps are under this 10 MB file limit, these days, our systems occasionally encounter sitemaps exceeding this limit. Most often this is caused when sitemap files list very long URLs or if they have attributes listing long extra URLs (as alternate language URLs, Image URLs, etc), which inflates the size of the sitemap file.
To address these evolving needs, we are happy to announce that we are increasing sitemaps file and index size from 10 MB to 50MB (52,428,800 bytes).”
For those unfamiliar with what are sitemaps, they are the way webmasters inform search engines about pages on their sites that are available for crawling.  Sitemaps are considered a key component in SEO  (Search Engine Optimization) strategies for some time as it allows for search engines to index sites more easily.
