You can boost your leads on Trulia a number of ways, and, as Larry mentioned below, being active in the Trulia Advice section is one of them. If you're looking to get more exposure for your listings, I encourage you to check out the Trulia Pro subscription packages we offer: http://www.trulia.com/truliapro/,
and if you're looking to expand your brand awareness, you'll want to check out Trulia Local Ads: http://www.trulia.com/localads/
and Mobile Ads: http://www.trulia.com/mobileads/.
The link below in the Web Reference section will take you to a video we recently posted about a Trulia Mobile Ads success story.
We do also offer you a few tools that should help you manage your leads and contacts. Your leads are all stored in your My Leads inbox on Trulia: http://www.trulia.com/inbox/
and they are also easily accessible when you're on the go with Trulia's Mobile App for Agents: http://www.trulia.com/agents/mobile/
In fact, the app will notify you instantly when you have a new lead so you can be sure to respond right away.
Paying customers also enjoy additional lead management features - Lead Alerts give you a phone call or text message when you receive a lead, and Lead Insight helps you identify serious buyers with additional lead information like move timeframe, pre-approval status and whether or not the buyer is already working with an agent.
I hope this helps.
