Thank you for your question. If you check out my profile you'll notice that the URL is customized: http://www.trulia.com/profile/emily/. You can customize your own Trulia Profile URL as well and add that link to your personal site so that your visitors can see your listings, specialties, interests and more.
To do so, access http://www.trulia.com/account/settings/ and click on the '[+] Edit personal info' button. Then create your customized URL in the 'Public profile' section.
I hope this works for you. Please let us know if you have any other questions.
I would direct this question to the Trulia folks, they are very helpful. But what I do is bring up what I want to link to and copy the address from the browser box or window - whatever that top line on the computer is.
