2. Google AdSense
AdSense is one of many ways to earn money from the web.
AdSense for content is a system of Google contextual ads
that can be placed on blog, search engine, or Web site.
Google, in return, will give a portion of the revenue
generated from these ads, on a pay per click (PPC) or pay
per impression basis.
3. Google restricts you from disclosing AdSense
details, such as how much you were paid for a keyword.
It is free to place AdSense ads.

websites with target audiences closely matching your

response rate for your ad campaign, and you’ll waste
fewer marketing money on ads placed on irrelevant
websites.

likely to visit.

6. Google has replaced the Google AdSense "i"
button on the AdSense ads with "Ad Choices."
When you go to a page with an AdSense ad, it
loads the ad and shows AdChoices in the top right.
Clicking on the AdChoices logo takes you to
the What are Ads by Google? and then lets you
report an issue at the bottom of the page.
So do not be surprised when you see the "i"
replaced by "AdChoices"
