Quick Look at www.gumtree.com

This is primarily an advertising site that’s mainly focused on things centered in the UK.  There’s listings for jobs in london, flats and houses to rent in and around London.  The front page of the site links to categories that contain the actual advertisements.  Just taking a few minutes to look around I noticed that there’s quite a lot of london jobs in a wide assortment of careers from full time to temporary.

Most of the advertising is free, with some sponsored links presented along with the free ones. Posting an ad is a straightforward process and once posted an ad can be edited.  Ads stay on the site for anywhere from 30 days to 90 days depending on the category they’re in.
