I'm excited to see that you're doing more than a couple things on the internet.
You are right...and I have found that GOOGLE loves Trulia..even more so than AR. Google placement from Trulia is withing hours while AR takes weeks.
I've been testing websites to see which have the best SEO and which get picked up the quickest by the Google.
Yup - besides trulia, I am "on" Active Rain, Linkedin, Zillow, Facebook, Twitter and a few others I probably forgot! My listings are all over the place, too!
Oh, I have a Google profile, too - can't keep up with it all!
Blogging on Active Rain
Answering quesitons and posting info on Trulia and Zillow
Occasionally writing articles on Examiner.com
Posting on Facebook.
Some posts automatically get picked up on Twitter
Can hardly keep up with these!
