Its not often that I beg for help, but Im really not sure where to turn. Ive posted my question on the google adwords forum and never even got a single reply.
I have been using adsense on my sites for roughly 4 years now.
I am unsure if I have a problem with adsense displaying on my sites. A few weeks ago I noticed that the adsense places on my sites were sometimes empty. Around the same time I noticed a drop in income and a drop in page impressions.
I started to make some observations on my sites and it appears that on occasion that the adverts dont show, it looks like the pages arent loading properly. Sometimes I get messages displaying at the bottom of the page such as :
Waiting for : googleads.g.doubleclick.net
transfering data from pagead2.googlesyndication
transfering data from googleads.g.doubleclick.net
transfering data from img.mediaplex.com
These are observations are made using firefox.
Recently I upgraded php version from 5.1 to 5.2. Could it be in anyway related to this ?
