8 Best Free Web Crawlers for Beginners

4 min read

If you are looking to get online web data, the three most used methods for this purpose are using an open-to-public API connection, building a web crawler program, and resorting to automated web crawling tools.

The former two both require knowledge of computer language. With a focus on beginners in web crawling, this article will be talking about free web crawlers for easy use and help you crawl data from websites quickly.

Why Do You Need A Web Crawling Tool?

With automated web crawling tools, crawling for web data (web scraping, data harvesting, or data extraction) is no longer the only privilege for programmers. Pick a free web crawler to start, you can:

  1. Get the needed data with no need to copy and paste.
  2. Export your data well-organized in different formats such as Excel, and CSV.
  3. Save you a lot of time and effort thereafter.

How to Choose a Free Web Crawler? 

You may have the similar question: Is there a real free web crawler? The anwser is YES. Besides the easy-to-use quality, what you should take into account when you are choosing a free web crawler:

Scalability/limit of use

What data you are looking for and how much are you aiming to scrape? If you want to start from a free web crawler and at the same time meet your need for data extraction, you should pay attention to how scalable the tool is and is there any limit of use for a free plan.

Data quality

In most cases, data is not the final end. What people are expecting from data is to generate ideas and insights or to guide their decision-making process. However, raw data from the web may not be applicable to analysis right away. What you have to do is to clean the data so that the computer can understand and help analyze it. To make this easier, you can choose a web crawler integrated with data cleaning features to free you from repetitive manual jobs.

Customer service

Even though automated web crawling tools have simplified much of the web scraping process for beginners, users could still encounter unexpected problems. Web crawling tools are not omnipotent because of the existing challenges in web scraping. With support from your side, you can have a smooth start and go further.
