Well recently i have heard that you should not submit your url to search engines and just let them find your site on other websites. for example.

Here is your website here

X <- Website (IF you just submit it, This will be the only found link and will have no affect in popularity.)

L - Here is your link on a site (Increases popularity/ rank)

L - Here is your link on another site (Increases popularity/ rank)

L - Here is your link on another site (Increases popularity/ rank)

Only if they are on high trafficked sites of course

With each link it increases your popularity right?

Well my english is bad sorry guys, I'm trying to make a point.

your right do both

Yes, both works. I submitted my site to the google index and also get now results including all the myspaces we're on. So whoever told you this was lying.
