SE Question
 

I performed submissions to SE's 2-3 weeks ago. If I wanted to make drastic changes to the site would this affect my sites ability to get listed.

probably not

nah they probably haven't even gotten to you yet

Changes from time to time are good... It normally takes around 1 week for google to catch up on you if you have some nice backlinks in place.

yahoo will pull your site off for an hour or more, but when its re-listed, it'll still be at the same position/ranking as it was before (unless you fucked with the meta tags)

Is there a free SE submission tool these days?

What a very strange idea you have of how on page optimisation and metas work these days. :1orglaugh

Submitting is not the best way to go about it folks.

Get your site linked to by 5-10 good ranking sies and you will see yourself cached in just hrs. I usually show up in google (cached) 3 days max after settign up a few links.

Take advantage of some linklists, linkdumps, and autohardlink trades to get some links in and let the spider naturally find your shit.
