is it time i think about cutting my content budget and just contact these few websites directly about advertising my site?
It seems I should, but I've never gone down that road and wanted to hear from some experienced advertisers out there...
Some things to be careful of:
If the sites are content sites, perhaps an idea is to help them out, write them a good article and ask them to reference back to your website with a link. That way you'll get some free advertising.
