HOW TO USE IT?
WHAT IS WEB SCRAPING?
Web scraping is an automatic 
method to obtain large amounts of 
data from websites. Most of this data 
is unstructured data in an HTML 
format which is then converted into 
structured data in a spreadsheet or a 
database so that it can be used in 
various applications.

perform web scraping to obtain data

PARTS OF WEB 
SCRAPPING
Web scraping requires two parts, 
namely the crawler and the scraper. 
The crawler is an artificial 
intelligence algorithm that browses 
the web to search for the particular 
data required by following the links 
across the internet. The scraper, on 
the other hand, is a specific tool 
created to extract data from the 
website.

HOW  WEB SCRAPERS 
WORK?
Web Scrapers can extract all the data 
on particular sites or the specific 
data that a user wants. Ideally, it’s 
best if you specify the data you want 
so that the web scraper only extracts 
that data quickly.

PRICE MONITORING
Web Scraping can be used by 
companies to scrap the product data 
for their products and competing 
products as well to see how it 
impacts their pricing strategies. 
Companies can use this data to fix 
the optimal pricing for their products 
so that they can obtain maximum 
revenue.

MARKET RESEARCH
Web scraping can be used for market 
research by companies. High-quality 
web scraped data obtained in large 
volumes can be very helpful for 
companies in analyzing consumer 
trends and understanding which 
direction the company should move 
in the future.

NEWS MONITORING
Web scraping news sites can provide 
detailed reports on the current news 
to a company. This is even more 
essential for companies that are 
frequently in the news or that 
depend on daily news for their day-
to-day functioning.

SENTIMENT ANALYSIS
If companies want to understand the 
general sentiment for their products 
among their consumers, then 
Sentiment Analysis is a must. 
Companies can use web scraping to 
collect data from social media 
websites such as Facebook and Twitter 
as to what the general sentiment 
about their products is.

scraping for email marketing. They 
can collect Email ID’s from various

send bulk promotional and marketing 
Emails to all the people owning these 
Email ID’s.
