Domain Crawler and Comparison Tool

Domain Crawler and Comparison Tool

This repository contains Python scripts to crawl and compare a website for changes.

Table of Contents

Overview

  1. capture.py – A web crawler that goes through all the pages of a given domain and exports the URLs, status codes, page sizes, and heights into both .txt and .html formats.
  2. compare.py – A script that takes two .txt files (generated by crawl_website.py), representing the old and new versions of a website, and compares them side by side. It exports the differences into an HTML file, highlighting the discrepancies.

Installation

Why use this tool?

  • Migrating to a New Platform/Host: Before switching to a new platform or hosting service, you may want to ensure that all URLs from the old platform exist in the new platform and function as expected.
  • Switching WordPress Themes: A change in theme may result in differences in content display, load times, or even broken links. Comparing the website before and after the switch can highlight these issues.
  • SEO Analysis: Ensuring that URLs, especially high-traffic ones, remain consistent during any changes can help preserve SEO rankings.
  • Quality Assurance: Before rolling out a redesigned website, comparing the old and new sites can help identify bugs, missing content, or other issues that need to be addressed.
