As part of content syndication , website content can be distributed to other users, i.e. publishers. However, scraping can violate these rules in many ways. There are websites that consist only of content that they have scrapped from other websites.
It is very common to find pages on the web whose information has been copied directly from Wikipedia without being able to find a source. Another case of spam scraping is that online shops copy their product descriptions from successful competitors. Often, formatting is applied directly.
It is important for webmasters to find out whether content is copied from other websites. In extreme cases, Google’s scraping can be blamed on the author, which could then result in a devaluation of the scraped domain. To know when content is taken over from other websites, alerts can be set up in Google Analytics , for example.
Search engine providers such as Google also use scraping to upgrade their own content with relevant information from other sources. For example, Google uses scraping methods to fill its OneBox or to design the knowledge graph . Find best google scraper here.
Webmasters can use simple measures to prevent their websites from being affected by scraping:
– Blocking bots via robots.txt
– Insert captcha queries on the website
– Use CSS to display phone numbers or email addresses
– Strengthening the firewall rules for the server
