A scraper site is a website that copies content from other websites using web scraping. The purpose of creating such a site can be to earn revenue, usually through advertising and sometimes by selling data. Scraper sites come in various forms, ranging from spammy content sites, to price aggregation and shopping sites, and also web search engines such as Yahoo and online maps such as Google Maps.

Search engines such as Google can be considered a type of scraper site. Search engines gather content from other websites, save it in their own databases, index it and present the scraped content to their search engine's own users. The majority of content scraped by search engines is copyrighted.

Made for advertising

Some scraper sites are created to make money by using advertising programs. In such case, they are called Made for AdSense sites or MFA. This derogatory term refers to websites that have no redeeming value except to lure visitors to the website for the sole purpose of clicking on advertisements.
