Custom Python Web Scraping for Any Website

Client Background

A mid-sized market research firm needed to aggregate pricing, product details, and customer reviews from multiple e-commerce sitesโ€”both static and heavily JavaScript-drivenโ€”to fuel their quarterly competitor analysis reports.

The Challenge

๐“๐ข๐ฆ๐ž-๐œ๐จ๐ง๐ฌ๐ฎ๐ฆ๐ข๐ง๐  ๐ฆ๐š๐ง๐ฎ๐š๐ฅ ๐œ๐จ๐ฅ๐ฅ๐ž๐œ๐ญ๐ข๐จ๐ง: Analysts were spending 20+ hours per Week copying and pasting data. ๐‚๐จ๐ฆ๐ฉ๐ฅ๐ž๐ฑ ๐ฌ๐ข๐ญ๐ž ๐š๐ซ๐œ๐ก๐ข๐ญ๐ž๐œ๐ญ๐ฎ๐ซ๐ž๐ฌ: Some target sites used dynamic loading, lazy-loading elements, and login walls. ๐ƒ๐š๐ญ๐š ๐ช๐ฎ๐š๐ฅ๐ข๐ญ๐ฒ ๐ข๐ฌ๐ฌ๐ฎ๐ž๐ฌ: Inconsistent structures led to missing fields and duplicate entries.

Objectives

โœฆ Fully automate data extraction from up to three target sites.
โœฆ Deliver clean, deduplicated, and structured output in their BI toolโ€“ready formats (CSV and JSON).
โœฆ Provide clear instructions so the in-house team could run or modify the scraper after handover.

Our Approach

Results & Impact

๐“๐ข๐ฆ๐ž ๐ฌ๐š๐ฏ๐ž๐: Automated monthly data collection reduced manual effort by 95% (from 20+ hours to under 1 hour of scheduled runs).
