Insights & Engineering

TL;DR: There is no official Google SERP API, so third-party providers fill the gap. Pricing ranges from roughly $0.30 to $15 per thousand searches, and the right choice depends on your volume, budget, and the SERP features you need to extract. This guide compares the top providers side by side, breaks down true cost at scale, and gives you a decision framework to shortlist the best SERP API for your project.

TL;DR: XPath and CSS selectors both locate DOM elements, but they solve different problems. CSS selectors are faster and more readable for straightforward selections. XPath wins when you need to traverse the DOM in any direction, match text content, or handle complex conditional logic. Most production projects benefit from using both strategically.

TL;DR: Axios routes requests through a proxy by accepting a proxy object with host, port, and optional auth fields. This guide covers how to set up Axios proxy configuration from scratch: basic wiring, authenticated proxies, HTTPS tunneling, a rotation system using interceptors, SOCKS5 via socks-proxy-agent, and diagnosing common errors. Every snippet is copy-pasteable Node.js code.

TL;DR: A Puppeteer download file workflow has four good shapes: click a button and let Chrome write to a folder you control, run fetch() inside the page and pipe base64 back to Node, drive the Chrome DevTools Protocol with download progress events, or skip the browser and pull the URL with Axios using cookies harvested from the Puppeteer session. Pick by file size, auth, and how the site exposes the link.

TL;DR: Node-Fetch has no built-in proxy switch, so you wire an HTTP, HTTPS, or SOCKS5 agent into the request through its agent option. This guide walks through how to use a proxy in Node-Fetch end to end: authenticated HTTP and HTTPS proxies, SOCKS5, rotation, retries, TLS edge cases, troubleshooting, and the modern undici route for Node 18+ native fetch.

TL;DR: Web scraping JavaScript tables in Python rarely needs a headless browser. Open DevTools, find the JSON endpoint that hydrates the grid, replay it with requests, paginate it, and fall back to Playwright only when the network call is signed, encrypted, or otherwise sealed shut.
