Web page scraper is a tool
designed to extract data
from web pages. It simulates
human navigation to gather
specific content.
Easy to Use
Efficient
Accurate
Cost-Effective
1. Identify the Target
Website
Research the website
you would like to scrape.
Ensure it is legal and
ethical to do so.
Use the browser’s developer tools to
examine the HTML structure, CSS
selectors, and JavaScript-driven
content.
2. Inspecting Page
Structure
Select a tool or library in a
programming language you
are comfortable with (e.g.,
Python’s BeautifulSoup or
Scrapy).
3. Choose a Scraping
Tool
4. Write Code to
Access the Site
Craft a script that
requests data from the
website, using API calls if
available or HTTP
requests.
Extract the relevant data from the
webpage by parsing the
HTML/CSS/JavaScript.
5. Parse the Data
Save the scraped data in a
structured format, such as
CSV, JSON, or directly to a
database.
6. Storing the Data
Implement error handling to
manage request failures and
maintain data integrity.
7. Handle Errors and
Data Reliability
8. Respect Robots.txt
and Throttling
Adhere to the site’s
robots.txt file rules, and
avoid overwhelming the
server by controlling the
request rate.
