Be default, All in One SEO has always dynamically generated sitemaps rather than output them as a file on your web server.
Dynamically generated just means that instead of a physical file being created on the server, the content is displayed in the browser when someone goes to the URL.
This is very common when working with Content Management Systems such as WordPress. Every page of content that WordPress outputs is dynamically generated from content in the WordPress database. This is inherently better than creating static web page files like web developers used to 20 years ago.
There are four reasons why we do this, these are:
- Dynamically generating a sitemap means it’s created every time it is requested meaning it’s always up to date and accurately reflects the state of your site at that moment in time
- Dynamically generating a sitemap is usually faster and requires less resources than writing to a static file. Search engines care about how long it takes to access your sitemap, so using a dynamically generated sitemap is much better and avoids them giving up when it takes too long to read
- A static file can be overwritten or deleted, or become corrupt or inaccessible due to server permissions issues. A dynamically generated sitemap doesn’t have these problems
- Writing to a static file is a complicated process, it requires a lot of code to accommodate different server configurations and can be prone to bugs and conflicts. Generating a dynamic sitemap is a natural part of how WordPress works so is more reliable.
