What Is Web Scraping? A Step-by-Step Python Tutorial

Learn what web scraping is and build a working Python scraper that exports website data to CSV. See when clean proxies improve access and reliability

Overview

What is web scraping and how does it work?

Automated systems generated more than 53% of web traffic in 2025, according to the Imperva 2026 Bad Bot Report. Many websites now respond to automated requests with rate limits, CAPTCHAs, browser checks, and IP reputation controls.

Reduce CAPTCHAs and failed requests with pre-filtered residential IPs. Test Gateproxies for $3.50 with 750 MB included.

A web scraper visits a page and extracts selected information from its HTML. Instead of copying product prices or article headlines manually, the scraper finds each field and saves it automatically.

A basic scraping workflow has six stages:

Designed for the job

The infrastructure behind the idea

When a workflow depends on public data, regional context, or stable sessions, proxy selection is part of the implementation—not an afterthought.

01

Research context

Separate the question you are asking from the route you use to collect or validate the answer.

02

Route selection

Match IP type, location, and session behavior to the target and the amount of traffic involved.

03

Validate first

Test a small, representative sample before turning an interesting idea into a production workflow.

How to scrape a website with Python

In short: Website URL -> HTTP request -> HTML response -> CSS selectors -> selected data -> CSV file.

Suppose an online store places a product title inside an h2 element and the price inside an element with the .price class. A scraper can find those elements on every product page and turn them into spreadsheet rows.

Web crawling and web scraping often appear in the same project, but they do different jobs. A crawler discovers pages. A scraper extracts selected fields from them.

For example, a crawler might find 10,000 product URLs. The scraper then collects the title, price, seller, rating, and stock status from each page.

Workflow

Web scraping techniques and tools

01 · Define the question

Turn the article’s question into a clear test.

02 · Choose a representative target

Choose a target that represents the real work.

03 · Select a route

Select a route that matches the target and volume.

04 · Run a small test

Run a small sample before making a broad claim.

05 · Review the result

Review the result against the original question.

06 · Document the method

Document what worked so the method can be repeated.

Details

What is web scraping used for?

Use this guide to frame the decision, then verify the current route and package details in the product pages.

Examples are starting points; test the target with a small, compliant request before scaling.

Practical guidance

Turn the research into an operating choice

The useful takeaway is a testable decision: what to route, where to route it, and how to measure the result.

01

Question

Write down the decision the research should help you make.

02

Test

Use a small, representative sample before assuming a tool or method scales.

03

Review

Keep a record of route, target, volume, and observed behavior.

FAQ

FAQs

Yes. Pick residential, mobile, or ISP Premium based on risk and session needs, then point your tool at the proxy host from the dashboard.
Residential and mobile use per-GB packages (billed monthly or pay as you go). ISP Premium is priced per IP. There are no free unlimited plans.
HTTPS works for most browser and scraper stacks. SOCKS5 is available when your tool prefers it.
Yes on eligible products. Hold the same IP for multi-step flows, or rotate per request for bulk collection.
