- Once the tool is configured, you can run it to extract the data. The tool will navigate through the website and extract the specified data. The extracted data can then be stored in a structured format for later use.
- The extracted data may contain errors, duplicates, or irrelevant information. Therefore, cleaning and processing the data before analysis is essential. It involves removing duplicates, correcting mistakes, and filtering out irrelevant information.
- Once the data is cleaned and processed, you can analyze it to gain insights and make data-driven decisions. Data analysis techniques - data visualization, regression analysis, and machine learning - can be used to extract insights from the data.
It should be noted that web scraping can be complex, and there may be some challenges along the way. For example, some websites may have measures to prevent web scraping, such as CAPTCHAs or IP blocking. Additionally, some websites may require authentication or login credentials to access specific data. Therefore, it is integral to be aware of the potential challenges and take steps to overcome them.
Web scraping can be a powerful tool for obtaining relevant data that can be used to drive business growth and research. However, it is essential to follow ethical and legal practices when using web scraping tools. Organizations must ensure they are not violating laws or agreements when using web scraping tools.

What Techniques Provide High-Quality Web Scraping?
The first method that comes to mind is that data can be collected manually by hiring people to track information on the resources of interest. But the productivity of such work will be low, and the possibility of error due to the human factor will be high. During the development of data science, web scraping has accumulated several proven techniques and tools.
1. Using web scraping tools
Automatic scrapers or click scrape tools offer an easy way to extract data.
- No programming knowledge is required. You only need to know which button to press.
- You can create 100,000 data points for less than $100.
- You can scrape millions of pages without worrying about infrastructure or network bandwidth.
- Even if websites use anti-bot protection mechanisms to prevent data collection, good scraping tools deal with these protection methods and ensure smooth operation.
- You can scrape anytime, anywhere, taking advantage of cloud-based tools infrastructure.
2. Own web scraping technical stuff
If your requirements are too hard to handle by a web extraction tool, consider building your team of developers and data engineers to transform and load (ETL) your data into a database (ETL). This approach allows you to customize according to your requirements, as well as manageability and flexibility. However, this approach requires money and resources.
3. API for data collection
Programming knowledge is usually required to use APIs that provide the required data. But as data requirements increase, so do costs. It is also not possible to personalize the data collection process.
