Twitter is catching on as more than a micro blogging, social networking, web 2.0 chat room. People are beginning to use search.twitter.com as a home away from Google. Twitter offers a real time feed for news, events, celebrity conversations, and the latest from your Uncle Joe. Now that Twitter crawls the links found in tweets and indexes the crawled pages, a whole new opportunity presents itself from an SEO stand point. Next time you post to Twitter, take a second to include a relevant link back to your site. Make sure you're not spamming your followers by including a witty remark in the tweet. Remember, it's about quality, not quantity. Include some keywords in your post, and make sure the page you are linking to is optimized for those same words. Lather, rinse, and repeat.
