XML Sitemap

Sitemap is always should be enabled. Slim SEO automatically generates XML sitemap (at domain.com/sitemap.xml) to submit to search engines. With XML sitemaps, your website are indexed fast and completely.

Slim SEO provides a styling for sitemap, which makes it look beautifully. See demo here.

To optimize the performance when generating sitemaps, the plugin splits the main sitemap (sitemap index) into a list of smaller sitemaps:

  • Post types: each post type has a sitemap.
  • Taxonomies: each taxonomy has a sitemap.

As Google suggested, the maximum number of links in a sitemap is 500. So the plugin generates links for latest 500 posts for each post type sitemap. That doesn’t mean old posts are not indexed. They should be indexed before. The current sitemap shows the fresh content that need to be indexed quickly.

Image Sitemap

Slim SEO also includes the image sitemap by default to make sure your images are discoverable by search engines.

All the images that you insert in the post content are added in the image sitemap. So, when someone search for your images, they’ll go to your posts to see the images.

The sitemap includes both self-hosted images and external images. Images in galleries or shortcodes are also parsed and included, too. For that reason, Slim SEO works with default WordPress gallery shortcode and other WordPress gallery plugins.

Sitemap and robots.txt

The sitemap URL is automatically included in the robots.txt on your website if your website doesn’t have a physical robots.txt file. WordPress automatically creates a virtual robots.txt for your website at domain.com/robots.txt. If you have a physical robots.txt, you need to add the sitemap URL by yourself.
