2) An ecommerce price scraper
Title: An ecommerce price scraper (Jun 2020 – Dec 2020)
Technology: Python 3.7
Role: Sr. Full Stack Developer
Description:
Price scrapers crawl a selected list of your competitors’ websites and extract prices, SKUs, product
names, and other useful information to help retailers compare their product prices and check that their
goods are competitively priced against those of their rivals.
While scraping product prices from an individual ecommerce website isn’t particularly difficult, it

becomes laborious when you need to scrape numerous websites. It usually requires you to develop site-
specific scrapers that extract product prices based on each site’s bespoke HTML markup. Since most

scrapers break when the underlying source code of the scraped pages is changed, this becomes a time-
consuming and expensive process and introduces lots of technical debt.

Approach: Approach is to instead scrape product prices from metadata or microdata embedded within
the page whenever possible. This structured data is added to most ecommerce product pages to help
search engines extract product data to enrich search engine results pages or allow searchers to
compare products via Google Shopping and other price comparison platforms.
By developing a price scraper that extracts microdata or JSON-LD using schema.org markup, a single
scraper can extract prices from many sites, avoiding the need to build a bespoke one for every
competitor.
