What is Web Scraping? A Beginner's Guide (2026)

What is Web Scraping?

Web scraping is the process of automatically extracting data from websites. Instead of manually copying information, a scraper reads the webpage's HTML and pulls out the data you need.

Common Use Cases

Price monitoring — Track competitor prices on e-commerce sites

Lead generation — Find contact information from company websites

SEO analysis — Extract meta tags, headings, and links from any page

Research — Gather data from multiple sources for analysis

Content aggregation — Collect articles, reviews, or comments

How Web Scraping Works

Step 1: Request

The scraper sends an HTTP request to a website (just like your browser does).

Step 2: Parse

The HTML response is parsed to find specific elements (titles, prices, emails, tables, etc.).

Step 3: Extract

Relevant data is extracted and structured into a usable format (JSON, CSV, spreadsheet).

Step 4: Store

Data is saved for analysis, monitoring, or further processing.

Web Scraping Without Coding

You don't need to write Python scripts or use complex tools. Krawly.io provides 170+ free scraping tools with a simple interface:

Content Extractor — Pull main content from any page

Table Extractor — Extract HTML tables as structured data

Link Extractor — Get all links from a page

Image Extractor — Find all images on a page

Email Finder — Extract email addresses from websites

Just paste a URL, click "Run", and download the results as JSON or CSV.

Is Web Scraping Legal?

Web scraping public data is generally legal. However:

Always respect robots.txt files

Don't overload servers with requests

Don't scrape personal/private data

Check the website's Terms of Service

Comply with data protection laws (GDPR, CCPA)
