How often should you check competitor prices?
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:
- If you review prices once a week, a daily check means you'll never be more than a few days behind.
- If you can change a price from your phone in two minutes, checking every few hours can pay off.
- If price changes need a sign-off from someone else, daily is about as useful as it gets.
Worked examples
These are made-up shops, to show how the two questions play out:
- A candle shop watching three rivals. Prices change for seasonal sales and new ranges, a few times a month. Daily checks catch everything in good time.
- A shop selling popular electronics accessories. Rivals adjust prices several times a week, sometimes the same day. Every few hours on the handful of bestsellers, daily on the rest.
- A coffee roaster watching other roasters. New coffees and limited lots appear without warning and sell out fast. Daily on each rival's shop page, so new lots don't slip past.
- A business buying from wholesale suppliers. Price lists change a few times a year. Weekly is plenty, but keep a dated record so you can spot a rise before the invoice does.
- A software company watching rivals' pricing pages. Plans change a few times a year, but each change matters. Daily is cheap insurance.
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:
- More alerts mean more to read. If most of them don't lead to an action, you'll start ignoring them.
- Big marketplaces limit automated visits, so very frequent checks there aren't realistic or polite.
- A price that changes back within an hour, such as a short flash sale, may not be worth reacting to.
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:
- The product pages for your best sellers, where you compete head to head
- A competitor's sale or offers page, which shows promotions as they start
- A category or collection page, which shows new products and price changes in one place
- Their delivery page, since a change in free delivery can matter as much as the price itself
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.
A simple routine to start with
- Pick your five to ten most important products and the rivals that sell them.
- Check them daily for the first month.
- Look at the history: how often did prices really move, and when?
- Move the busy ones to more frequent checks and the quiet ones to weekly.
- Step it up for Black Friday and January sales, then step it back down.
