How to Track Prices on Any Website

Price tracking is simple in principle: a tool watches a product's page and tells you when the price changes so you can buy at the right moment instead of refreshing the page yourself. The catch is that most trackers only work on Amazon.

This guide shows you how to track prices on any website, and how to choose the tool that fits where you actually shop.

How price tracking works

Every price tracker does the same four things:

1. Checks a product page on a schedule (every few minutes, hourly, daily).
2. Reads the current price on the page.
3. Compares it to the last value it recorded.
4. Alerts you when the number changes.

The differences between tools come down to three things: where they can do this (one store or any website), how they run (a website, a browser extension, or a native app), and what they can watch (just price, or stock and other details too). Everything below is a variation on those four steps.

Track your first price in three steps

1. Download and open SmartTracker.
2. Click +, then paste the product URL.
3. Click the price on the page, then confirm.

That's the whole setup. From there it starts monitoring on a schedule and alerts you whenever the value changes.

Your options, from built-in to any website

The right one depends on where you shop and how you want to be alerted. Here's the current landscape, as of August 2026:

• Browser built-ins. Chrome's "Shopping Insights" and Google Shopping's Track price show price history and can alert you on drops, but only for products in Google's shopping catalog, and mainly on desktop.
• Retailer alerts. Some stores email you when a price drops or an item restocks. Free, but inconsistent and different at every store.
• Amazon-only trackers. CamelCamelCamel and Keepa are genuinely great for Amazon, but they can't help if you shop elsewhere.
• Web monitors. Tools like Visualping and UptimeRobot watch any page you point them at, but they're built to monitor entire sites and priced for it: an account, and a monthly bill that grows with the pages and checks you need.
• Native apps. SmartTracker tracks any store from your own iPhone, iPad, and Mac, needs no account, and sends you notifications when any value changes.

Track more than price

Price isn't the only thing worth watching. A good tracker can also tell you when something's back in stock: point it at the "Out of stock" label and get pinged when it changes. Beyond that, any number or text on a page can be tracked: a percentage-off, a rating, a stock count, even a status line. If it's on the page, a capable tracker can watch it.

Store-by-store notes

• Amazon: either an Amazon-only tracker (Keepa, CamelCamelCamel) or an app that monitors any website; Amazon also has a built-in price history now.
• Walmart, Target, Etsy, Shopify stores, niche brand sites: these need a tracker that can watch any site. Amazon-only tools don't work here.
• Anywhere else: if you can open it in your browser, SmartTracker can track it.

Set a target price that actually triggers

An alert only helps if the target is realistic. A few rules of thumb:

• Aim roughly 10–25% below the current price for electronics; smaller for already-discounted items.
• Watch seasonal windows; big sale events and end-of-season clearances move prices more than random days.
• Focus on high-value purchases first, where even a small percentage saves real money.

Which tracker should you use?

It depends on where you shop. If you only ever buy on Amazon, CamelCamelCamel or Keepa will serve you well and cost nothing. If you're monitoring pages that aren't products at all, look at Visualping.

If you shop across several stores and want the alerts on your own devices, that's SmartTracker, a private price-tracking companion for iPhone, iPad, and Mac. Track prices on any website, set alerts, and see clear price history so you can buy at the right moment.
