I'm running several campaigns at the moment. To be honest I've not seen great conversions from the content results, so disabled it - quite happy with the return from search.
However, I have noticed that some sites that I would expect to be search (eg excuse the url drop http:*//www*.ntlworld.com/searchresults/search_ntlworld.php?q=secured+loans&cr=) seem to be showing content results.
Is this just me? Can anyone else that has disabled content but left search see themselves in the results page above (obv with a diff query!).
