Web scraping basically boils down to extracting data from websites, and this process is automated through bots that gather website data. The scraping process involves data locating and extracting techniques. This system can scrape data from anywhere and is not limited to the web.

Web crawling vs. web scraping of web pages the main differences

Web scraping allows you to extract content or any kind of data from any website. This system copies pixels on the screen and an underlying HTML code alongside data from a database. Using this method, you can replicate the whole webpage if you need to. This automated process is also known as web harvesting or web data extraction. It fetches a web page. Web crawling is regarded as the central part of scraping since it downloads pages for further usage.

Web scrapers gather specific info from some web page; if you need to find out about prices on websites such as Amazon or any other e-commerce platforms, you can do it with a little help from web scraping.

To draw a comparison with web crawling. This term comes from crawlers of search engines. Web crawlers scan the whole internet to index websites. Google or Bing use their own web crawlers.

But most of the time, web crawling is the prerogative of Google, Yahoo, Bing, and the like. These bots search for specific info about websites, whereas web scraping programs target websites from some particular areas like e-commerce or stock markets.

Do you need proxies for web scraping?

Proxy management is an essential thing for any web scraping efforts. In this article, we will tell you about the crucial aspects of proxies used for web scraping.

An IP address is a number that consists of digits, every device connected to the internet has this number.

Proxies are third-party servers that make it possible for users to process the requests of users adding their own IPs. Thus, when you visit some website, it sees a proxy IP address, not your real one. And this mechanism allows you to scrape the web without exposing your real location.
