Python Web Crawlers: Guide to Building, Scaling, and Maintaining Crawlers

TL;DR: A web crawler is a program that systematically navigates the web by following links from page to page. Python is the go-to language for building crawlers thanks to libraries like Requests, Beautiful Soup, and Scrapy. This guide covers everything from your first 50-line crawler to a production-grade Scrapy setup with proxy integration, JavaScript rendering, and distributed architecture. If you've ever had to collect data from hundreds or thousands of pages and done it manually, this is for you.

Mastering Scrapy for Scalable Python Web Scraping: A Practical Guide

Scrapy is a powerful web scraping framework available in Python. Its asynchronous architecture makes it faster than sequential scrapers built with Requests or Beautiful Soup, and it includes everything needed for production-ready scraping: spiders, items, pipelines, throttling, retries, data export, and middleware. In this guide, you'll learn how to set up Scrapy, build and customize spiders, handle pagination, structure and store data, extend Scrapy with middlewares and proxies, and apply best practices for scraping at scale.

The Ultimate Guide to Scraping eCommerce Websites: Tools, Techniques, and Best Practices

Manual eCommerce data collection breaks because the data doesn’t stay stable. Prices change daily, products disappear and reappear under the same URL, and even mid-sized stores list tens of thousands of SKUs. On top of that, much of the content is rendered with JavaScript, layouts shift due to constant A/B testing, and anti-bot systems detect repeated automated access. This guide shows you how to analyze a target site and choose the right extraction approach.

Proxy Anonymity Levels: Transparent vs Anonymous vs Elite

Not all proxies actually protect your identity. Some proxies openly tell websites, "This request came through a proxy," while some can even leak your real IP if they're configured poorly. There are three proxy anonymity levels: transparent, anonymous, and elite. This article will walk you through each one, explain how they work, and help you choose the most suitable option for you.

From Concert Tickets to Cart Prices: Can AI-Powered Pricing Be Fair?

Dynamic pricing is everywhere – from the flight you booked last week to the headphones in your cart right now. But as AI-powered algorithms grow more sophisticated, adjusting prices millions of times a day based on demand, competition, and increasingly personal data, a critical question is emerging – is this still fair? We analyzed over 1.5M eCommerce price changes and introduced our second-annual Dynamic Pricing Index to find out what’s really happening beneath the surface.

Top 5 Countries Leading the Dynamic Pricing Revolution

Dynamic pricing, the practice of adjusting product prices in real time based on demand, competition, inventory, and other market signals, has become one of the defining features of modern eCommerce. Once limited to airline tickets and hotel rooms, algorithmic pricing now touches nearly every product category, from groceries and fashion to electronics and home improvement supplies. Our second-annual Dynamic Pricing Index, compiled from over 1.5M data points tracked at four-hour intervals across more than 120 eCommerce platforms in 40+ countries, reveals the scale and sophistication of this practice.

How Retailers Are Still Playing Mind Games With Your Wallet

There's a reason that a flat-screen TV costs $999 instead of $1,000. That grocery item rings up at $4.99, not $5.00. Your new sneakers are priced at $79.95, conveniently avoiding the psychological cliff of $80. It's called psychological pricing, and according to our Dynamic Pricing Index report of over 1M price observations on 120 eCommerce platforms, it's not just alive and well in eCommerce. It's absolutely everywhere.

Web Scraping at Scale Explained

Scraping projects usually start simple: a Python script, the Beautiful Soup parsing library, and a list of URLs. That's enough for small jobs. Once you're past a few hundred thousand pages, you start hitting problems: timeouts, IP bans, parsers returning empty fields because someone changed a div to a span. At that point, it's not a coding problem anymore, it's an infrastructure problem. This guide covers the architecture, proxy management, anti-bot evasion, pipelines, costs, compliance, where the industry is headed, and build vs. buy decisions.

What Is a Proxy Server? How It Works, Types, and Use Cases

TL;DR: A proxy server acts as an intermediary between your device and the internet, masking your IP address and routing your requests through alternative IPs. Businesses use proxies to bypass geo-restrictions, avoid blocks and CAPTCHAs, scrape web data at scale, verify ads, monitor prices, and maintain online anonymity. With the proxy market projected to reach USD 3.12 billion by 2032, understanding which proxy type fits your needs can make the difference between seamless data collection and constant roadblocks.

How To Find All URLs on a Domain

Whether you're running an SEO audit, planning a site migration, or hunting down broken links, there's one task you'll inevitably face – finding every URL on a website. It sounds simple, but it isn't. Search engines don't index everything, sitemaps are often outdated, and dynamic pages hide behind JavaScript. This guide walks you through every major discovery method, from quick Google search operators and no-code scrapers to custom Python scripts.
