Google AdSense

Google AdSense, also known simply as AdSense, is a high paying affiliate program network owned and run by the search engine giant Google. It provides advertisement units to publishers, who have to sign up for the program network which enables them to use their publisher account to earn money through the ads posted by Google on their website / blog. Each publisher gets a unique ID upon signing up, which is used to generate ad codes for their website so they can start earning cash. You can see why adsense is on of the top affiliate networks for website and blog owners alike just by looking at our pros and cons list.
Pros

    Low traffic requirements: If your website contains unique content of good quality, you will have no trouble getting approved, since it requires very little traffic – 100 or more unique visitors each day, regardless of whether your blog/site has a sub level domain or a top level domain.
    Multiple monetization options: As a publisher, you will not be restricted to earning cash through posting ads directly on your website – you can monetize through search, feed, videos, mobile site, and online games etc.
   
   Multiple language support: Google AdSense is the sole publisher network to allow posting ads in languages other than English. In fact, over thirty different languages are supported!

    No waiting time for ads to show up: Because of the very long list of advertisers present in Google AdWords, ads will start showing up in your Ads space the moment you supply the ad code on your blog.
  
   Multiple ad formats: Text ads, display ads, link ads, rich media ads and video ads are all the various formats in which you can post ads on your website to earn money.

    Highest revenue share for publishers: As compared to other publisher networks, you’ll earn a greater cut of the revenue if you employ Google AdSense. For content, the revenue share is 68 percent, whereas for search, the revenue share is 51 percent!

    Country specific payment methods: Depending on the country you reside in, Google AdSense will let you receive your payments using options which are readily available in your country.

Cons

    Strict uniqueness restriction: If even a single article on your website gets flagged as plagiarized, you won’t be able to get your AdSense application approved. This also includes the content which was originally yours, and was copied by another party.

    Payment threshold: You won’t be able to withdraw earnings under $100, which can be a bother for smaller businesses.
