Hi, I have about 60 or so domains (and looking to expand). I've been displaying google adsense adverts on these until they recently closed my account (I believe this is happening to more and more domain parking sites). I'm looking for a good PPC publishing company similar to adsense where you can put one bit of code onto many websites and get context related adverts. My sites are all PHP based so I can alter the code depending on the SEO phrase for each page, but many companies expect you to create specific adverts for each site and this would take forever. Some also require you to get each site approved manually. Any suggestions or recommendations?
