Is Indexing Necessary if using Attracta
I have not signed up for any indexing under "Options: Indexing". I have, through my webhost, a service called Attracta that rebuilds my sitemap whenever I want and then submits it to the search engines. I assumed that this was a way for the search engines to pick up my backlinks. Is this so? What exactly does the link indexing do, and is it something that gets done anyway, but maybe faster if one uses the Indexing services? Do most people use the GSA indexing or are there others out there?
Thanks,
