Web Crawling is Easier with Scraping Tools

Any business looking to extract useful information from the internet will find it easier to do so using web scraping tools.

Web crawling is an automated data collection technique that allows you to avoid the repetitive work of copying, pasting, and typing data from the internet. It is also referred to as web or data scraping. A web crawler is also known as a crawler, bot, or web spider.


How Do Web Crawlers Work?

Web crawlers – such as Google – index web pages and their content based on specific policies and algorithms. The information is then analyzed and categorized into an index for easy retrieval.

The indexed pages contain new and updated information. Web users are thus easily and quickly served the most relevant information whenever they perform search queries.

Web crawlers crawl known web pages regularly to find out whether there are any changes in the page’s content since the last crawl. If any changes are detected, the search engine updates its index in response to the new changes.

By using web crawling software, you can scrape an unlimited amount of information from websites, which is then processed and packaged in a structured format. This makes it easy to read. Web crawling tools can be either free (opensource) or paid.

It’s important to note that web crawling can also be used negatively to scrape classified, private or restricted information.

Types of Web Scrapers

1. Self-built or Pre-built

You can build your own web scraper – if you can write code. If not, there are many pre-built web scrapers available for download, with some offering advanced options like scrape scheduling and JSON exports.

  1. 2. Browser Extension vs Software

Generally, web scrapers come in the form of browser extensions or computer software. Web scraping extensions are easy to use and can be integrated into your browser. Alternatively, you can download web scraping software and install it on your computer.

While some web scraping tools use a minimal UI and a command line, others boast a full-fledged UI where the user just clicks on the data requiring scraping. People with limited technical know-how prefer the latter.

Local web scrapers run on your computer resources and internet connection while cloud-based scrapers run on an off-site server.
