What is web scrapping?
The process of collecting large amounts of data from websites is called web scraping. The data collected through scraping will be available in unstructured HTML format. This process can be carried out using bots, online services, particular APIs, or sometimes by creating specific codes. Web scraping requires two sections, namely a scraper and a crawler. While a crawler is an Artificial Intelligence (AI) algorithm used to browse and find particular data or information with the help of links available on the internet, a scraper is the particular tool used for this extraction. The scrapers vary largely depending on the requirement and complexity of the scraping projects.
Some websites allow you to access their data in a structured format. Major websites like Google, Twitter, Facebook, and more are some such websites. Although this is an easy task, some websites do not allow data extraction, making web scraping essential to collect data. However, why are these data collected? What are the uses of these collected data? Various businesses and digital enterprises use this data. While certain people illegally use web scraping, the legal uses of scraping include search engines crawling websites to analyze and rank their content, price-comparing websites collecting price and product details, and digital marketing companies collecting data from social media forums and campaigns.
What is the working mechanism of web scraping?
Web scrapers can be used to extract all the data from a particular website or collect specific or required data. Although it is allowed to collect data for legal uses, it is best advised to collect only the required data as the process can be carried out easily and quickly. However, how does the process work? Below are the steps involved in web scraping:
1. Provide the URL
The URL of the target website should be provided to the web scraper.
2. Load the HTML code
Once the URL is provided, the scraper will load the HTML code of the website.
3. Data extraction
Depending on the given instruction, the scraper extracts the whole or specific data available on the website.
4. The final output
As a final procedure, the extracted data will be provided in an accessible format by the scraper.
When can you use web scraping?
As mentioned, web scraping is used for multiple purposes across industries. Some of the most important uses of this process are:
Price monitoring
Through web scraping, companies can gain access to the product details of their competitors. So, it helps them determine an ideal price for their products with maximum profit.
Research about the market
By scrapping the details from different similar websites, you can have a basic understanding of the market and its trends. It will help you analyze the interests and likes of their target audience.
