I was looking and see one of the adsense plugins for wordpress was banned and the developer lost his/her account. There are more plugins bu I am hesitant to use any, is it ok to put the adsense code on SSI and include them into templates or other pages without using any plugin?
I am not sure of the plugin that was targeted by adsense but there is no issue using an SSI as long as you don't change the code. Did the plugin alter the code in anyway?
Adsense Deluxe alters the code if you check the donate 5% of the impressions to the developer! it will change your pub-id but I don't think it's illegal since digitalpoint forums are doing this!
Without changing the code in any ways, like encrypting it, you won't get banned. I am using adsense in my blog without using any plugin. It is elementary and tailored just for the purpose. If you would like to drop an eye on an article that i have written, see my home page in my profile.
