· Why Do You Need A Web Crawling Tool?
With automated web crawling tools, crawling for web data (or web scraping, data harvesting, data extraction) is no longer the only privilege for programmers. Pick a free web crawler to start, you can:
Get the needed data with no need of copy and paste.
Export your data well-organized in different formats such as Excel, CSV.

· How to Choose a Free Web Crawler?
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. 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.
