ok here is a question that I have often wondered about. On our site we have done all the
SEO ourselves and are happy with the results but would like better, obviously.
I have read the jargon from various
SEO companies saying what they will do for your site etc etc. One of the things that was listed is that they will submit your site to the major search engines an a monthly basis.
Surely this is crap?

Why would sites need to be resubmitted regularly to the search engines? Would you say that this is just padding out the service that they are providing?
