I've been using AdSense for years, but as my traffic gets higher, I'm starting to suspect that it might not be the best fit anymore. I think I need a mixture of advertising programmes and dedicated advertisers. However, finding and managing advertisers isn't something I have time to do myself, as I'm busy working on the content of the site. I've been trying to find a company who will do it for me, but am finding it difficult (despite being inundated with spam offers). Does anybody have any recommendations, please?
