Bing is the second most powerful search engine after Google. In as much as most people pay close attention to everything Google, using Bing can go a long way in ensuring that your content attains more exposure, attracts more traffic and ranks better in the search engines. If you are yet to create a sitemap for Bing, now is the time so long as your CMS or site can handle it. Alternatively, you can install any of the available sitemap plugins that will take care of all the technicalities for you. In fact, you are always free to use a sitemap generator for this purpose.
If you choose to create your sitemap manually, then you need to stick to the following best practices, especially for Bing but they can apply with any other search engine.
Even though the above best practices may apply for small websites, they may not really be suitable for large sites with millions of URLs. Therefore, as you try to create sitemaps for such websites, it is advisable to prioritize which of the many URLs you consider important and deserve inclusion on your sitemap. It is misleading to assume that the search engines can magically crawl and index millions or even billions of URLs from a single website. Therefore, consider linking only the most relevant pages.
The above best practices are not exclusive to Bing sitemaps because they can also be used in helping you create sitemaps targeting other search engines like the giant Google.
Create, edit, customize, and share visual sitemaps integrated with Google Analytics for easy discovery, planning, and collaboration.
