Why is web scraping needed in WordPress?

Web scraping (web harvesting or web data extraction) is a computer software technique of extracting information from websites. Web scraping is closely related to web indexing, however, web scraping focuses more on the transformation of unstructured data on the web, typically in HTML format, into structured data that can be stored and analyzed. Web scraping is also related to web automation, which simulates human browsing using computer software. Uses of web scraping include online price comparison, contact scraping, weather data monitoring, website change detection, research, web mashup and web data integration.

Using WP Web Scraper, you can easily embed external content from websites (HTML), structured data feeds (RSS, ATOM, XML, JSON, CSV etc) with ease and mostly without the need of any coding. The possible implementations of this are limited only by your imagination.

While scraping, you should consider the copyright of the content owner. Its best to at least attribute the content owner by a linkback or better take a written permission. Apart from rights, scraping in general is a very resource intensive task. It will exhaust the bandwidth of your host as well as the host of of the content owner. Best is not to overdo it. Ideally find single pages with enough content to create your your mesh-up.
