Tagging and pinging are probably one of the most overused techniques to get search engine bots to crawl your website. Ping was especially overused during the time when "blog and ping" was the so called "killer technique" out there.

Usually a ping occurs when a blog is updated. Think of a ping as being a signla to the rest of the servers alerting them that a blog has new content. The ping servers will then visit the blog to check for updates and one of various methods will be used to display your blog updates on the web. So, in theory this helps to get your blog indexed by the search engines because there are many different sites which you can ping all of which will increase the awareness of your blog and its purported relevancy in the mind of the search engine bot.

Tagging saw a dramatic rise in 2006 picking up on a technique that tag sites like Del.icio.us have been employing since 2003. Tagging allows you to tell "social bookmarking" sites to associate certain web pages with certain tags. Tags and keywords. This is useful because the public can search these social bookmarking sites and potentially bring up your site in the results, thus bringing traffic.
