This really depends how the listings are being submitted to us.
If we receive a new data feed with listing information the listings in that feed should go live on Trulia in approximately one week.
If a website is submitted to us for crawling, the initial setup to crawl the site will take one to two weeks before those listings will go live.
However, once that feed or site is live in our system any updates made to the feed/site should go live on Trulia in approximately 24 hours. Although, depending on exactly when the feed/site is updated and when our own data cycle starts this can take just a bit longer. I'd say that 72 hours should be the longest amount of time that should take.
