Bulk submitting your site to search engines is quite an easy task. Granted, it may sound spammy, but it’s not. This session covered things like XML site maps and paid inclusion options. Google gave an overview of their webmaster tools and gave tips like having separate XML site maps for different types of media (like mobile) and removing un-necessary information from the urls (like session ids). Yahoo talked about Yahoo Site Explorer and said that more features were on the way. They noted that a feedback area launched recently and it was a great way to put in your opinion on what was missing orbroken. It also comes with Digg like functionally so users can vote on topics. The more votes, the quicker Yahoo will consider working on it. Overall, XML site maps is the way to go to make sure you get all your URLs indexed by the major search engines.
This is also a good time to point out the XML site map post that I made a while back.
