Ads are getting so smart that if you are looking for something, say a cell phone, plane ticket etc, you will be targeted by the Ad from vendors to show up on your page (side, top, bottom etc).
Example: Looking for cheap plane ticket to Asia, the ad will be shown on my page and all you need is to click on the ad to find out the prices available to you. Actually prices presented are NOT bad at all.
