1. Web Content
2. User Geographical Location

• These Ad contents are related to the website content and User's preference.

Why Google AdSense is popular and best:

• Google uses responsive Ads for websites or Blogs, which automatically adjust upon user device to show the Ad efficiently.
• These Ads are less intrusive, and the content of advertisements will be related to websites.
• Many websites make revenue from AdSense and even small websites make revenue from AdSense.

Google needs from website publishers to serve their Ad:

1. Good Quality Content: It want to attract the readers and provide good reader experience.
2. The website should be constructed under webmaster guidelines.
3. They don't need page full of advertisements. They only need limited number of advertisements in a webpage.
4. Don't try to encourage users to click Ad.
5. Don't redirect to poor reputation website.

Google has removed the policy of limiting the Ad. Now, publishers can place several Ad in same website. But main content of the page should be visible clearly. (Ad should not exceed page content).

• Each time when the end user visits the page. the JavaScript code uses inline JSON to display content fetched from Google's servers.
• For contextual advertisements, Google's servers use a web cache of the page created by its Media Bot "crawler" to determine a set of high-value keywords. If that keyword has been cached already, advertisements are served for those keywords based on Ads bidding system.
