I made some significant changes to a website I have to help it come up better in yahoo and Google searches. Is there a way to request the spiders to crawl on over to my site and check it out again, or is there any way to speed up the process?Can I request to have a spider visit my website?Resubmit your website to Google, Yahoo, MSN, and DMOZ.org.
Highly recommend you go to Google and get their webmaster tools and place a sitemap in your web.
