How to track changes to a website
To track changes to a website, save the page's text on a regular schedule and compare each new copy with the last one word by word. Ignore parts that change on every load, such as dates and ads, so the alerts you get are about real edits.
Pick the right pages
Pricing, terms, job posts and product pages change in ways that matter. Home pages change constantly and mostly do not.
Compare words, not pixels
A screenshot comparison flags a moved banner. A word comparison tells you the price went from 49 to 39.
Keep the history
A saved copy of each version lets you prove what a page said on a date, which helps in a dispute with a supplier or platform.
Quick answers
Can I do this by hand?
Yes: save the page text, paste both versions into a word diff like ours, and repeat. It works for a few pages.
How often should I check?
Daily suits most pages. Prices on busy stores can change several times a day.
