General Knowledge about Data Scraping
Do you really know data scraping and its tools?
Do you also have difficulties and losses in picking up a data scraping tool? Data scraping is no longer a new phrase nowadays; if you don’t know what they mean, let me do a quick intro for you. Data scraping, web scraping or data extraction all mean using bots to extract data or content from a website into a usable format for further uses. A data scraping tool is important because it helps people to obtain a large amount of information in a timely manner.
In the world we live in today, companies compete against each other with massive information collected from a multitude of users — whether it be their consumer behaviors, content shared on social media or celebrities following. People collect information before making decisions, such as going over the reviews to decide whether to buy the stuff. Therefore, at least you should have some web scraping knowledge in order for further use or to be successful.
Although we live in the generation of big data, many businesses and industries are still vulnerable in the data realm. One of the main reasons is due to the minimal understanding of data technology or their lack. Thus, it is necessary to make good use of data scraping tools. In today, data scraping tools or web scraping software is an essential key to the establishment of a data-driven business strategy. You can use Python, Selenium, and PHP to scrape the websites if you know the coding language. As a bonus, it is great if you are proficient in programming. However, don’t be anxious if you don’t know any coding language at all. Let me introduce some web scraping tools to facilitate effortless scraping.
Nowadays, there are more and more data scraping tools being created in the marketplace. Some tools like Octoparse, provide scraping templates and services which are a great bonus for companies lacking data scraping skill sets. On the other hand, some of the web scraping tools require you to have some programming skills in order to configure advanced scraping, for example, Apify. Thus, it really depends on what you want to scrape and what results you want to achieve. If you have no idea about how to get started with data scraping tools, follow me and start from the very beginning with basic steps.
3 basic steps to get started with data scraping tools
First, spend some time studying targeted websites. It doesn’t mean you have to parse the web pages. Just thoroughly glance over the web pages. At least you should know how many pages and what data on the websites you want to scrape. Do some notes and that will be good for the scraping later.
Second, pay attention to the website structure which means its HTML structure. HTML consists of a series of elements which tells the browser how to display the content. Some websites are not written in a standard manner. That being said, if the HTML structure is messed up and you still need to scrape the content, you need to modify the XPath.
If you don’t know what XPath is, check out What is XPath and how to use it in Octoparse.
Third, find an appropriate tool. After learning your targeted websites and its HTML structure, you should have some ideas about them and your data requirement. Then you can go through some data extraction software in the marketplace. Do some research, no matter if you search online, ask friends or try any other methods. Finally, consider comprehensively and make a decision based on your own situation.
If you don’t know any data extraction tools and don’t know where to start. Below are the lists of some personal experiences and thoughts in regards to scraping tools. I hope it can offer you some insights.
