Minimum Number of Pages Required for Google Adsense

How many pages required by Google for Adsense? I'm not Adsense expert but sometimes my friends who learn to create a web page ask me about Adsense to earn money for ads placement in their websites.

Google don't give the minimum amount of pages required to join Adsense, but it is important that Google need pages with high quality content. The website must contains plenty of rich information that includes relevant keywords, used appropriately, that indicate the subject matter of the content.

The website that may will be banned from Google Adsense include:

Autogenerated content
Automatically generated content is content that’s been generated by computer program or script. Often this will consist of paragraphs of random text that makes no sense to the reader but which may contain search keywords.

Doorway pages
Doorway pages are typically large sets of poor-quality pages where each page is optimized for a specific keyword or phrase. In many cases, doorway pages are written to rank for a particular phrase and then funnel users to a single destination.

• Having multiple domain names targeted at specific regions or cities that funnel users to one page
• Templated pages made solely for affiliate linking
• Multiple pages on your site with similar content designed to rank for specific queries like city or state names

Scraped content and thin affiliate sites
Scaped content is content taken from other sites to increase the volume of pages on a website. Example of thin affiliate sites:

• Sites that copy and republish content from other sites without adding any original content or value
• Sites that copy content from other sites, modify it slightly (e.g.: by substituting synonyms or using automated system), and republish it
• Sites that reproduce content feeds from other sites without providing some type of unique organization or benefit to the user
• Sites dedicated to embedding content such as video, images, or other media from other sites without substantial added value to the user

It is important for a site displaying AdSense to offer significant value to the user by providing unique and relevant content, and not to place ads on auto-generated pages or pages with little to no original content.  Your site should also provide a good user experience through clear navigation and organization. Users should be able to easily click through your pages and find the information they are seeking.

So, it's not a question of the number of pages, it's the content that is contained within them. If you still ask me about how many pages required for Google Adsense, maybe in my humble opinion, I can say that 6 month worth of daily posts with original content is good for the start.
