However, like any other external link, this takes your customer to someone else's site. They may not necessarily return to your site. It can take up to six weeks from the time your submission is placed until they enter your site into the search engine data base. Be patient with the process. Also, some search engines may drop your listing after a few months, apparently because they do not update it often enough.
Search engines send their spiders out regularly to verify that pages still exist.
The spiders also check to see if we have updated the pages. One benefit you gain from the checks that the search engine spiders make is automatic updating. When you change your meta title, meta keywords or meta description, the spiders will pick up those changes the next time they index your site. Therefore, resubmitting changes is unnecessary for you.
