Use the signature link in your DP posts , this site gets crawled all ythe time.. Put your new post . page or site in your sig link and when you post on the forum your link will get picked up..
Make sure your robots.txt file doesn't have any entries that can prevent your site being indexed. In case you haven't heard of them, a robots.txt file is mostly used to tell a complying search engine spider to keep away from certain files or directories. Valid entries look something like this (this would tell all spiders to keep away from the /forums and /stats directories): User-agent: * Disallow: /forums Disallow: /stats With Google delivering so much traffic, it is only normal to be eager to submit your page and have it indexed as soon as possible. The Google folks have also made it clear that Google gives a page more importance when it is found through an automatic crawl. This can be easily verified when we consider how Google's PageRank system works: when page A links to page B, part of page A's PageRank trickles down to page B, increasing page B's PageRank (and, therefore, its importance). A manually submitted page will not enjoy this benefit. The best way, at least in my personal experience, is to write an article on your area of expertise and submit it to popular article syndication sites. You can submit a site to Google, but in most cases you won't need to. Google's spiders will follow inbound links to your site and find it for themselves. If your site doesn't have any inbound links then you should submit it, although without them it will probably not be a very successful site. Try to get at least one inbound link - a local or country specific business directory is often a good place to start.
You need to build a site with fresh content and then submit it to top bookmark site. Finally add your sitemap to Google webmaster site .
