How often should you check competitor prices?

By the ChangeGist team · Updated 5 November 2026 · 6 min read

Check too rarely and a rival quietly undercuts you for a fortnight. Check too often and you drown in alerts you can't act on. The right answer depends less on your tools and more on two simple questions about your market. This guide walks through them, with examples for different kinds of shop.

The short answer

For most small online shops, once a day is plenty. Move to every few hours only if your competitors change prices during the day and you can actually respond that quickly. Once a week is fine for slow markets, such as trade supplies or price lists that change a few times a year.

If you're not sure, start with daily and adjust after a few weeks of real history.

Question 1: how often do their prices actually move?

Some markets reprice constantly. Others change twice a year. Before picking a schedule, find out which one you're in. Watch a handful of competitor pages for two or three weeks and look at the history: how many changes, on which days, and at what time.

You'll often find a pattern. A rival might run a sale every first weekend of the month, or update prices every Monday morning. Once you know the rhythm, you can check around it.

Question 2: how fast can you respond?

There's no point knowing about a price change within the hour if it takes you three days to update your own shop. Match your checking to your reaction time:

Worked examples

These are made-up shops, to show how the two questions play out:

Check more often around busy dates

Prices move most around big retail moments: Black Friday and Cyber Monday, the run-up to Christmas, Boxing Day and January sales, and end-of-season clearances. It makes sense to check more often for those few weeks and drop back afterwards.

The same goes for your own launches. If you're about to cut a price or run a promotion, keep a closer eye on how rivals respond in the days after.

When checking more often stops helping

More checks are not automatically better:

A good test: if you've never acted on an alert within an hour of getting it, you don't need hourly checks.

Watch the right pages

How often you check matters less than what you watch. For most shops, a few pages do most of the work:

Make alerts tell you something useful

An alert that just says “this page changed” sends you off to work out what happened. Look for one that tells you the old and new price, and ideally how that compares with yours.

ChangeGist's price check does this. You enter your own price for a product and the competitor pages that sell it, and it emails you when someone undercuts you, and again when you're the cheapest once more. Other changes, like new photos or reworded descriptions, are filtered out as noise.
