Re-directing expired pages

Need to handle pages that expire with correct http response

Hi,

I have a section on one of my sites that allows registered users to post classified adverts/job vacancies etc. The ads last for 4 weeks and then are no longer displayed. Users have the option of re-activating the ads for 2 weeks after they expire.

At the moment if an expired ad page is requested from a SERP or by a crawler I'm using a 301 redirect (using php) to the ads section home page. Is this the best way to go about this? I'd appreciate any advice from anyone who's done something similar.

Cheers
