Publisher programmes are helpful to get the extra cash and some people rely on publisher programmes for a good monthly income. Moreover on this subject some people that own big
website hostings and get hundreds of pounds from publisher programmes such as Google Adsense don't go to work because they get sufficient profits for a monthly income. However you need to be wary because some people know about Googles rules and click numerous times and get you banned. I have used publisher programmes before such as Clicksor but I have never used Google Adsense because of their strict policies on their publisher programme. I have heard time and time again people are getting banned from Google Adsense.
