It's called Adsense and it's one of the many ways the HDN helps pay the bills and can afford to have #ninjaweek every year and many other things that you see here on HDN.
What is AdSense?
AdSense is a program that allows bloggers and website owners to make money by displaying Google ads. You’ve probably seen the ads all over the place, including in Google search results. Basically, Google gets the largest cut and you get a small percentage. There are two ways to make money from AdSense:
Impressions – this is based on the number of pageviews of pages or posts with ads
Clicks – this is based on how many people click on the ads.
To make it as basic as possible, you sign up for an AdSense account and add the code to your blog or website. You can choose how your ads look, where they show up, and even what kind of ads you’ll accept. Once you get to a minimum threshold of $100, Google will either send you a paper check or make a direct deposit into your bank account.
@sirdizzy when you were off on another part of the internet and were searching for iolite goggles through Google you were using Google Adsense and you didn't even know it. Now fast forward to when your back here at HDN and we use Adsense and it remembers what you've been searching for and can find through the many affiliates where you can get a good price on some. I can assure you though that it's not stalking you, it's basically just keeping you within the loop so to speak and readily available should you decide you want to purchase a pair after all.
I'm always searching for electronics and when I come back here to HDN I see a lot of the same ads inciting me to go buy what I was so enthralled at looking at.
