So you have a new website and want it to get indexed by Google, Yahoo and Bing? No problem. Here are the submission pages for each one. Just submit your homepage, and they will crawl the rest of your site if it’s built or you have an XML (or regular) sitemap page.
Google: http://www.google.com/addurl/ (no account needed)
Yahoo: http://siteexplorer.search.yahoo.com/submit (you will need a Yahoo account to submit a site to Yahoo)
Bing (MSN): http://www.bing.com/docs/submit.aspx (no account needed)
As stated on Google’s Webmaster Blog at Blogspot, they do not (and have not for a while) used Meta Keywords to impact their algorithmic ranking for web search. They do state that they can use it for enterprise search, but not general web search.
However, don’t go deleting your Meta Keywords just yet. This blog post by Randy Duermyer illustrates a test they did showing that Yahoo does utilize Meta Keywords currently in their algorithmic ranking. When the company doing the website removed the Meta Keywords from a website, the rankings in Yahoo dropped. When the Meta Keywords were restored, the rankings returned. Here is another article describing Yahoo and MSN using Meta Keywords.
