The ultimate guide to web scraping for everyone
In this post, we’ll find out how to use web Scraping Tools & APIs to perform fast and effective web-scraping for single-page applications. This will help us gather and use valuable data that isn’t always available via APIs. Let’s dive in.
What is web scraping?
Web scraping may be a technique used to extract data from websites using certain tools or API. We extract data for either business purposes or for Data analysis. Here we are getting to specialize in tools that will be employed by both Developers also as Non-developers.
We perform web scraping because the target website has not exposed its API. Here are some common web Scraping scenarios:
- Scraping Ecommerce websites for product data.
- Scraping Hotel booking websites for collecting reviews, ratings & pricing of the hotel.
- Scraping Emails for targeting customers.
- Scraping financial websites for data analysis or for preparing a machine learning model.
Getting started with web scraping is straightforward and it’s divided into two simple parts-
- Employing a web scraping tool to form an HTTP request for data extraction.
- Extract important JSON data by parsing the scraped HTML data.
For web scraping tools we are getting to use Scrapingdog. They provide 1000 FREE credits & their services are often easily used directly either from their Tool or API.

You have to stick to the URL of the website you’re scraping.
Paste the key of your account, which is out there right above this tool.
Then you’ve got a Premium proxy option which enables you to use premium proxies for websites that are harder to scrape.
Then you’ve got a geographical position proxy that helps you to urge local data of any country.
The last three options are for specifying HTML attributes & tags using which Scrapingdog provides us JSON data directly from scraped HTML data.
