Question 1

how do I track when a competitor goes out of stock?

Accepted Answer

You monitor their product pages on a schedule and record each time an item flips to out of stock or back in stock. On Shopify stores the public products.json endpoint exposes stock state cleanly, while other sites need the availability markers read straight off the page. Doing this by hand across a full catalog is not realistic, which is where a done-for-you feed helps, we build and run the monitor so you just get a clean signal the moment stock changes.

Question 2

how often should I check competitor inventory for stockouts?

Accepted Answer

It depends on how fast the category moves. Fashion and limited drops can sell out in minutes, so a 10 minute cycle makes sense, while slower categories are fine on an hourly or daily check. We run monitors as tight as a 10 minute cycle in production, for example across roughly 3,000 Myntra products, so the cadence is a setting rather than a limit.

Question 3

is it legal to monitor a competitor's stock levels?

Accepted Answer

Collecting publicly available data, the same product and availability information any shopper can see on the page, is generally accepted, and public data is the only thing we collect. We do not log into private accounts or touch anything behind a paywall. This is general information and not legal advice, so check with your own counsel for your specific situation.

Question 4

what should I do when a competitor runs out of stock?

Accepted Answer

A competitor stockout is redirected demand you can capture, so the common plays are raising your bid on the keywords you both target, featuring the matching product, and holding or nudging your price up while you are the only one in stock. The catch is timing, because the window closes the moment they restock, so the value is in knowing within minutes instead of days. A live stock feed is what turns that into an action you can take rather than something you notice too late.

Question 5

can you tell how much stock a competitor has left?

Accepted Answer

Sometimes. Some stores, including many on Shopify, expose a quantity or a low stock flag you can read, while others only ever show in stock or out of stock. Even the simple in or out signal is enough to spot sell-through when you track it over time and watch how fast items flip. We capture whatever the page exposes and keep the history, so you see the trend and not just today's snapshot.

Question 6

should I build a competitor stock tracker or buy one?

Accepted Answer

A basic checker is easy to prototype and hard to keep alive, because sites change layouts, add anti-bot defenses, and break your scraper right when you have stopped watching it. If tracking competitor stock is core to your margins, a done-for-you service means someone else owns the maintenance and you simply consume the feed. We have kept monitors running through anti-bot protection on sites like Booking.com and Expedia, so reliability at scale is the part we take off your plate.
