Your business can benefit immensely from web scraping. Web scraping techniques enable you to automatically extract large amounts of data from websites. Although you may already have information-gathering processes in place, scraping is much more efficient at sifting through the mountains of data on the internet, and providing you with only relevant data. By using a good proxy server, you can do this anonymously as well. If you’re ready to learn more about web scraping, read on.

Getting started

Web scraping offers multiple options for you to achieve your goals. For example, you are not limited to any one programming language. So you are free to choose according to your preference. However, many people opt for Python because of its simplicity and its wide selection of libraries, including Requests and Scrapy.

Choosing the right tool

In addition to the programming language, there are also several scraping tools from which you can choose. To select the right tool for you, you need to look at how the data will be delivered, the effectiveness of the anti-scraping techniques, the ability of the tool to adjust to the size and spread of the job, and how good is the customer support. Be sure to check for proxy support as well, in case there’s a chance of getting blocked. Without the right tool, your business won’t be able to scrape the data you need to grow. The actual steps involved in scraping are relatively simple, as you’ll see below.

Step 1 – Making a request

The first step in the scraping process is identifying your target website. Then you’re ready to request the contents of a specific URL from this website. The web scraper you are using will then gather the requested information in HTML format.

Step 2 – Parse and extract

Parsing is the next step, which involves analyzing the HTML code and then producing something that the computer understands and can use. Essentially, HTML parsing is just the extraction of relevant data and assignment of it to its proper role in the final output. That can include paragraph text, links, and headings, among other elements.

Step 3 – Storing Data

Next, save and store the data. You can choose to save the data in CSV (Comma Separated Values), JSON (JavaScript Object Notation), or in a database. This gives you local access to the data for further analysis.

Working with a proxy server

After you’ve learned how to scrape and have chosen a web scraper tool, it’s equally important to use a good rotating proxy server, since it’s almost impossible to scrape extensively without one. When you’re up and running, a service like ProxyMesh can not only help you to scrape efficiently, but also enhance your overall security while helping to avoid IP bans.

Easy access to information

Information is a highly valuable commodity for businesses and individuals alike. Great business strategies depend on reliable data. Make sure you can access and make full use of the information available. Web scraping gives you this data quickly, in an organized structure. Moreover, it delivers the data in a storable format of your choice. Pair your web scraping tool with a reliable proxy server and you’ll have a winning combination.
