Scraper site

Source: Wikipedia, the free encyclopedia.

A scraper site is a website that copies content from other websites using web scraping. The content is then mirrored with the goal of creating revenue, usually through advertising and sometimes by selling user data. Scraper sites come in various forms. Some provide little, if any material or information, and are intended to obtain user information such as e-mail addresses, to be targeted for spam e-mail. Price aggregation and shopping sites access multiple listings of a product and allow a user to rapidly compare the prices.

Examples of scraper websites

Search engines such as Google could 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.[1]

The scraping technique has been used on various dating websites as well. These sites often combine their scraping activities with facial recognition.[2][3][4][5][6][7][8][9][10][11]

Scraping is also used on general image recognition websites, and websites specifically made to identify images of crops with pests and diseases.[12][13]

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.[14]

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

Some scraper sites link to other sites in order to improve their

private blog network. Prior to Google's update to its search algorithm known as Panda, a type of scraper site known as an auto blog was quite common among black-hat marketers who used a method known as spamdexing


Scraper sites may violate

copyright violation, if done in a way which does not respect the license. For instance, the GNU Free Documentation License (GFDL)[15] and Creative Commons ShareAlike (CC-BY-SA)[16] licenses used on Wikipedia[17] require that a republisher of Wikipedia inform its readers of the conditions on these licenses, and give credit to the original author.[original research?


Depending upon the objective of a scraper, the methods in which websites are targeted differ. For example, sites with large amounts of content such as airlines, consumer electronics, department stores, etc. might be routinely targeted by their competition just to stay abreast of pricing information.

Another type of scraper will pull snippets and text from websites that rank high for keywords they have targeted. This way they hope to rank highly in the

feeds are vulnerable to scrapers.

Other scraper sites consist of advertisements and paragraphs of words randomly selected from a dictionary. Often a visitor will click on a

advertisement on such site because it is the only comprehensible text on the page. Operators of these scraper sites gain financially from these clicks. Advertising networks claim to be constantly working to remove these sites from their programs, although these networks benefit directly from the clicks generated at this kind of site. From the advertisers' point of view, the networks don't seem to be making enough effort to stop this problem.

Scrapers tend to be associated with link farms and are sometimes perceived as the same thing, when multiple scrapers link to the same target site. A frequent target victim site might be accused of link-farm participation, due to the artificial pattern of incoming links to a victim website, linked from multiple scraper sites.

Domain hijacking

Some programmers who create scraper sites may purchase a recently expired

private blog network
to power their own photography site.

Services at some expired domain name registration agents provide both the facility to find these expired domains and to gather the HTML that the domain name used to have on its web site.[citation needed]
