Essential for websites not already in search.
Gives search engines a map to your site.
Speeds up the discovery of your website.
If your website is brand new, on a never-before-used domain name, no-one will know it exists, not even search engines. Submitting your site directly to the search engines is a fast way to make sure as much of your content gets discovered as quickly as possible. The theory goes: If you build it, they won’t come – unless you tell them it’s here and invite them to visit!
