We are now using Twitter (after the effort required in getting it set up and working) to link back to our newest posts. You can view our not-very-exciting twitter page at: twitter.com/zylstra555
This be thanks to a plugin called: “WP to Twitter“
WP to Twitter automatically links back to my new posts (using a URL shrinking thingymabob) and lets people know whenever I make a new post. Advantages obviously include more visitors and a different way (other than RSS) to track new posts.
WP to Twitter has an easy to use settings interface with relatively simple questions. Either URL Shortening service (unless you choose to use WordPress) requires either an API key or registration of some kind — this is very easy and does not hurt. It is also (though I have not tested it) compatible with Google Analytics Campaign Manager for tracking your Twitter users.
Quite frankly, I hate twitter. This should also assist in placing Google results as well..
