refreshing rental ads

[Michael Faurest]

Hi everyone, I have an opening right now in one of my houses.  I have an agent that is listing it but I was listening to one of the podcasts and the guest was discussing how he refreshes his ads every 2 hours to drive leads to the list agent.  It seems like craigslist is protective of this activity.  Does anyone have any creative ideas on how to refresh ads to maximize visibility?  I'm currently using Cozy listing and my agent used zillow to aggregate to all the other sites.  Thanks!
