Concept of "Made for AdSense" Websites.

Google, Yahoo, Napoleon and Josephine
A scraper site is a website that copies all of its content from other websites using web scraping. A search engine is not a scraper site: sites such as Yahoo and Google gather content from other websites and index it so that the index can be searched with keywords. Search engines then display snippets of the original site content in response to a user's search.

In the last few years scraper sites have proliferated at an amazing rate for spamming search engines. Open content are a common source of material for scraper sites.

Made for AdSense
Some scraper sites are created for monetizing the site using advertising programs. In such case, they are called Made for AdSense sites or MFA. This is also a derogatory term used to refer to websites that have no redeeming value except to get web visitors to the website for the sole purpose of clicking on advertisements.

Made for AdSense sites are considered sites that are spamming search engines and diluting the search results by providing surfers with less-than-satisfactory search results. The scraped content is considered redundant to that which would be shown by the search engine under normal circumstances had no MFA website been found in the listings.

These types of websites are being eliminated in various search engines and sometimes show up as supplemental results instead of being displayed in the initial search results.

Some sites engage in "Adsense Arbitrage"--they will buy Adwords spots for lower cost search terms and bring the visitor to a page that is mostly Adsense. The arbitrager then makes the difference between the low value clicks he bought from AdWords and the higher value clicks generated by this traffic on his MFA sites. In 2007, Google cracked down on this business model by closing the accounts of many arbitragers. Another way Google and Yahoo are combating the proliferation of arbitrage are through quality scoring systems. For example, in Google's case, Adwords penalizes "low quality" advertiser pages by placing a higher per click value to its campaigns. This effectively evaporates the arbitrager's profit margin.
