what is web scraping and how it is works.

What is web scraping?

Web scraping is a way to collect information from all over the public internet, and it can be used in many different ways

Web scraping is a term for various methods used to collect information from across the Internet.

Web scraping is not a new concept. In fact, some would argue that it's always been around; before the internet was even a thing, people were collecting data from across the web. Web scraping is defined as "the process of extracting information from websites." It can be used to collect all kinds of data such as prices, dates and times, images and text. Once collected this information can be analyzed for trends or patterns that could prove useful to an organization or business.

Web scraping is also known by other names: crawling and screen-scraping are two terms that are often used interchangeably with web scraping but there are some differences between them:
  • Crawling refers to accessing content within individual websites (or sections) without having direct access rights; screen-scraping implies using an automated program (script) which extracts certain parts of a web page rather than visiting multiple sites at once like crawlers do - usually via API calls made through HTTP requests/responses sent back-and-forth between servers on either end of said request/response chain; crawling requires less resources than screen

What is web scraping used for?

Web scraping is used in a variety of business scenarios. It can be used to:

  • Monitor prices online and compare them to competitors' prices.
  • Generate leads and capture information that can be used to contact potential customers.
  • Collect sales intelligence data on what products are selling, where they’re selling, and when they’re selling.
  • Scrape contact information from websites or social media platforms so you can reach out directly to potential customers.

Price monitoring and price comparison from web scraping

You may have seen sites that monitor prices for you. They do this by scraping the web and comparing the price of a product from many different retailers. Web scraping can be used to find the optimal price for any given product, helping consumers save money on their expenses.

A common example of web scraping is price comparison sites like pricegrabber.com These sites allow users to compare prices across multiple online retailers in order to find the lowest possible rate for an item they’re looking to buy.

Lead generation via web scraping

In short, web scraping is a way to collect data from across the internet. There are several ways to use this data:

  • Sales Intelligence
  • Contact Scraping
  • Content Scraping (i.e., scraping reviews on Yelp or YouTube videos)
  • Price Monitoring and Price Comparison

Sales intelligence via web scaping

Web scraping is a way to gather information about your prospects, customers and suppliers. Web scraping can help you identify opportunities and understand the competition.

Let’s take a look at how web scraping can be used to find leads:

Identify new leads based on their location or authority in the industry by using social media data. For example, if you want to target CEOs in Portland, you could scrape LinkedIn for users who work at companies located in Portland and have “CEO” as part of their title. You could then send them an email with some information about your product or service (or whatever it is that you do). You would be able to get into their inboxes because they are local business owners who care about helping other businesses succeed; if nothing else works for getting them interested then maybe this method will!
Pull all of the tweets from people who follow your competitors so that there's no chance of missing out on any potential leads who might otherwise slip through the cracks due simply due not being aware yet (or maybe even actively ignoring) what's going on around them right now - especially since every tweet contains valuable information like where someone lives/worked/went school etcetera which can be used later down line when sending out emails advertising certain products/services specifically targeted towards those demographics only (i.e.: those living near Cleveland).

Contact scraping and content scraping are both forms of web scraping.

The most common types of scraping are contact scraping and content scraping. Contact scraping involves collecting contact information from websites like email addresses, phone numbers, and mailing addresses. Content scrapers can collect data using APIs (application programming interface) or by taking screen shots of the website and then interpreting what's on screen. This type of web scraping is also known as web data extraction.

Scraping bots are used to retrieve information from websites that have been coded in HTML language, which is a way to write text for display on the internet. The bot will go through each page one at a time until it has read all the pages needed by its owner. You can use different types of software programs to do web scraping depending upon what kind of data you need and how much time you want to spend collecting it:

  • Desktop applications - These programs run directly on your computer or laptop with some requiring installation before running them for first use; others will run immediately after downloading them but may require updating later if newer versions become available at no cost once installed successfully onto your device
  • Browser extensions - Browser extensions work similarly as desktop apps except they're designed specifically for use within browsers such as Google Chrome or Firefox rather than being installed onto machines themselves--therefore making them more accessible because users don't need administrative privileges when installing them either offline or online (depending upon whether they come pre-installed).

It's a way to collect data from all over the internet, and it can be used in many different ways.

Web scraping is a way to collect data from all over the internet in one place. It can be used in many different ways, like price monitoring and price comparison, lead generation, sales intelligence, contact scraping and content scraping.


In summary, web scraping is a great tool for businesses. With so much data out there, it's important for companies to collect as much of it as possible so they can make good decisions about their products and services. Web scraping lets them keep tabs on what their competitors are doing, which means they don't have to rely solely on guesswork when making decisions about pricing or product lines. It also helps salespeople reach out to potential clients with relevant information when they're looking at different suppliers' websites
