Recently I did some search on 'cheap hosting solution'... as I was planning to host my blog...and after that.. no matter which site I was visiting... I started to see Google Ads by hosting companies like bluehost, hostgatar.. For example. I visited www.samsungupdated.com and I see hosting Ads by Google. Shouldn't be Adsense be related to content on website. I mean, i should see ads related to mobile there..not hosting. Does this happen to everyone or Just me experiencing this. Why I'm asking this? I heard people suggesting building websites around keyword for higher CPC. Can anyone guide me how we can have content related Ads?
The ads are personalised. If I look at tshirt designs on RedBubble I'll see those exact designs in ads on other sites for the next few days. If I visit a website that is an advertiser I'll see that website being promoted for days Think about it, does Samsung really want to see their competitors ads on their website? They'd rather have something else you are interested in being promoted.
Usually the ads are related to your browsing, so, if you've visited those sites in the past you will see ads from them. That's called remarketing
