Hi, I manage about 5-6 sites and using google adsense in all sites. I have just a little question that, Can I use one script in my all sites or will I have to create individual ads for each site. for example, I created a 120 x 600 ads for one site "mydomain1.com" Can I use this same ads script to "mydomain2.com" and "mydomain3.com" ? Will this effect on my earnings? You help would be appreciated. Thanks
Yes, you can use the same script, it wouldn't affect your earning. The only disadvantage is you can't track the individual site earning
You can use the same adsense, but you might consider creating additional channels in your adsense so you can track each site better, and ctr, etc. much more accurately. But if you want to use the exact same code for all your sites go for it. Only takes a few seconds to create additional channels though.
