I have been using Adsense on my WordPress sites for sometime and has been getting good revenues too. 3 months back, there was a sudden rise in my traffic and my host asked to start caching my pages. Luckily I came across this WordPress plugin called WP-Cache which caches your posts, pages etc...And since then I didnt have any issues with my host though the traffic never dropped. Now today I thought of making some changes to my adsense layout in one of my blogs. I just needed to change the text color on a 468x60 banner from black to gray. I made the change in my Adsense Deluxe plugin and then checked the blog post. But the color didn't change. I rechecked with the Deluxe plugin and it was updated correctly. It took me about 5 minutes to recall the WP-Cache plugin which I installed months back. I went to the WP-Cache plugin options and cleared the cache. Then I checked the blog post and now I can the see the color change. It was at this point that I started thinking until now whether my pages were showing Adsense ads dynamically. I mean the Cache plugin basically cached the page to such an extend that even the color of the adsense ads remained the same. But if the color didn't change, did the ad itself change every time a visitor hit the page? Any idea?
Any code or html on the page is cached whereas the javascript that generates the AdSense ads is run on the client side... which means that isn't cached.
Thanks guys. I was just wondering why it didnt update the ad text color when I changed it. Nice to know WP-Cache is ok with Adsense.
