Let me give two examples of ads that I don't find disrespectful:
- On one of my informational websites, I have sets of Amazon links underneath the articles. These are ads of books, handpicked by me, to fit the subject of the article. They are quite useful to the reader who wants to go deeper into the subject. The ads are not put into the face of the visitor, but are at the exact spot where he or she might genuinely be interested in getting to know more. And, of course, these are not animated ads.
- The ads that Google places to the right of search results are an excellent example of respectful advertising. No blinking, no video, no sound, just text. Totally relevant. I even click them, when I'm looking to buy something.
I used to find Adsense acceptable, and hadn't blocked it. A bit ugly, usually, but not distracting or annoying. But then I got ads that I thought could only have gotten there through profiling, Google having registered something about my having an impending death in my family, and serving "relevant" ads. I was very much insulted, and then added Adsense to my block list.
