Other new features in Squirrly SEO are Sitemap XML and Robots.txt.
Squirrly informs Search Engines about all of your articles, posts, custom posts, tags, and it also sends information about the images and videos from each article, in order to be indexed in the image and video sections of the Search Engines.
Your articles will be pushed to Google and Bing only when they become public, rather than on every update, in order to prevent getting banned.
Squirrly does not physically create the sitemap.xml file, or the robots.txt file. This is the best choice if you use the WordPress Multisite option.
