A Web scraper is a great data mining software mostly used by data miners and analysts to gather big datasets over the World Wide Web. It is a tool to automate the process of web scraping with efficient data mining techniques, which would otherwise be impossible to do manually. As data collection through web scraping becomes more and more critical for most businesses, the need for a better web scraper also becomes a necessity. So, in this article, we will tackle the relevance of web scrapers and how you can use this amazing tool for your projects even without any technical or programming skills.
Data Mining in a Nutshell
Before we dive deep into web scrapers, let us briefly discuss data and data mining. The term “data mining,” also known as “knowledge discovery in databases,” was coined in the early 1990s and is the process of data harvesting or digging through large data volumes to identify patterns and connections that can be used to predict future courses. The fundamentals of data mining comprise several scientific disciplines including analytics and statistics. However, as our technology advances, artificial intelligence and machine learning have played a significant role in the process of mining big data.
According to studies, the total amount of data generated worldwide has reached 64.2 Zettabytes as of 2020, and data creation will continue to grow and triple over the next five years. This is why automation in web scraping or data mining is essential. Without it, you will not be able to take advantage of the vast resources available since gathering valuable data in a reasonable amount of time for any of your work will be hard.
Web Scraper - A Modern Tool for Mining
In this modern age, you will need data if you want to do market research and lay out the best business strategies. The most efficient way to gather a vast amount of data and access relevant information is through web scraping. The term “web scraping” refers to extracting any data from a target website. The information collected is then used for various reasons, such as data analysis, marketing research, SEO campaigns, and more. A web scraper is simply a tool that will allow web scraping automation.
It may sound very straightforward right now, but the truth is scraping websites is not an easy task. See, most websites do not like bot crawlers repeatedly accessing their content for any reason. Almost all websites nowadays have some sort of bot detection program or algorithm that will instantly block any suspicious activity, and web scrapers can easily trigger these types of security. This is why choosing the most suitable scraper will significantly affect your data mining success.
Choosing the right Web Scraping Tool - Things to Consider
As someone looking to extract valuable data throughout the internet, you will require a tool capable of accomplishing the task efficiently. Web Scraping is a resource-intensive endeavor and can be tricky without the proper knowledge of what factors you need to consider when looking for a scraping tool. There are several things to keep in mind when deciding, so we have listed some meaningful insights.
Ease of use - One of the reasons why you need a web scraper in the first place is the functionality it offers and how well it can make your life easier. It is one of the most important factors to consider when looking through a list of data mining tools and choosing the one that won’t waste your time focusing on how to use the tool. It should be well-documented and straightforward.
Scalability - A highly scalable tool is a must if you are planning to scrape huge amounts of data for any of your projects. The amount of data available online only increases over time, so it makes sense that your chosen data mining software should be easily scalable if you want to expand in the future.
Quality of Proxies - As a data miner or analyst, you will have to be wary of CAPTCHAs and other bot detection algorithms deployed by websites as they can prevent you from achieving your goals. CAPTCHAs are made to stop bots and web scrapers from sending too many requests from one source via automation and can effectively be bypassed or avoided using rotating proxies.
Pricing transparency - Just like any other service, the pricing structure is an important aspect to look at. Before signing up, users should be aware of added fees. As a provider of the service, these fees should be disclosed to all customers. Setting up your own tools for web crawling is a tedious task and costly for most individuals. Most businesses also prefer to avail proxy services from other companies for their web crawler. So, finding the right data mining software with fair pricing is always a must.
Customer Support - It is not an actual feature of the tool but is an important part of the overall experience when availing of a service or product. It is a necessary function of any business if they want to have successful products or services. As a customer, you deserve to have a good customer support experience, especially with data mining tools like a web scraper, where most of the functions are in the backend and will usually require technical knowledge to troubleshoot.

Extracting Data using a Web Scraper
Now that we have discussed several pointers on how to pick the best data mining software based on your needs let us show you a great example of how to utilize a scraper to extract data from a website. For this example, we will be using Crawlbase’s Scraper API to demonstrate how straightforward the process is. The Scraper API does not require you to have advanced knowledge in terms of coding to use it effectively. The API can be used by itself and can be executed via a web browser or terminal in three simple steps.
Step 1: Create your account and obtain an API key.
Create an account at Crawlbase to get your 1,000 free API requests. Go to your account’s dashboard afterward and copy your private token.
Step 2: Knowing the basics of the Scraper API.
Making your first API call is very easy. You just need to remember the base endpoint of the API and where to insert the website URL you wish to scrape. To understand it better, let’s break it down into three parts:
The Scraper API endpoint:
https://api.crawlbase.com/scraper
Your private key or token:
?token=API_KEY
The target URL:
&url=encodedURL
If you are not familiar with how to encode the URL, you can simply use this URL Decoder/Encoder page.
As a good practice, it is always recommended to read the product documentation before using it.
Step 3: Make your first API call.
With all the parts of a call combined, you can now send your request to the API and let it do the rest for you. Below is a complete example of a Scraper API call with the encoded URL:
1 | https://api.crawlbase.com/scraper? |
This can be executed in several ways, but sending it via your browser is the easiest. Just copy the line, paste it into the address bar, and hit enter. You will automatically get the parsed content of the website within seconds, as you can see in the example output below:
Since the Scraper API is highly scalable, it will be quite easy to build a fully automated web scraper on top of it or integrate it into any existing system or app. Crawlbase also provides a wide range of libraries and SDKs to aid users with the expansion or integration of the API.
