1) The sites you were searching were the ads matched the page content or purely IAB ads? If yes then is it possible that there is a combination of IAB and content related ads.

No. Zero relevance to the pages. It was 100% IAB.

2) What about the sites you own or run? Do you see the same ads on your site as well?

Yes, I do. And my sites have nothing to do with the ads, zero.

3) Suppose Once you clicked on the IAB ad made purchase, after that also you see those same ads? Or they disappear after you purchase the material? Sorry to miss the point in your post. You said discount ads popped up. Whether those discount ads were for same or similar product you purchased?

The ads reflect my most recent search activity, regardless of whether I had already purchased or not.

So according to your experience IAB works.

Only to the extent that I am clicking ads for the first time in my life. But otherwise, not really. :) Only what I stated in the title and in my previous post: "I am only stating that for the first time in my life I am clicking on AdSense ads."
