They ran a coupon and your conversion dipped

Why it is free
SellerMate is an Amazon ads automation platform, and that is the part people pay for. The tracker is free because a seller who finds out the same day their position slipped is a seller who eventually wants the bid changed automatically — and because we would rather be the tool you already have than the one you evaluate. Nothing here is funded by selling your data, and there is nothing to sell: every check reads public pages.
Why this one
Public data, no permission needed
The same search results and product pages any shopper sees, collected on a schedule instead of by hand.
Three to five ASINs, not forty
A feed of everything gets muted. A threshold on the rivals that actually take your sales does not.
A position alert can answer itself
When a rival overtakes you on a keyword, the bid on that keyword can go up inside your cap.
Set one alert. That is the whole job.
Paste an ASIN, a keyword, or an Amazon link
No Amazon login, no seller account, no card.
Set the line that matters
One rule per ASIN — usually “price drops 10%” or “they climb above me”.
Choose where it reaches you
WhatsApp, email, or both — and who on your team gets it.
Decide what happens next
Read it and act, or let a position rule raise the bid inside your cap.
Competitor monitoring FAQ
Checks run on a schedule, up to four times a day, between 07:00 and 21:00 in your marketplace timezone. So the honest answer is same day, not instantly. A change at 09:10 typically reaches you within a few hours; a change at 22:00 reaches you the next morning. Anything promising real-time Amazon monitoring is either polling harder than Amazon tolerates, or rounding up.
No. Checks and alerts run on public data — the search results page and the product page, exactly as a shopper sees them — so you can watch any ASIN, including products that are not yours. Connecting an Amazon Ads account is optional and unlocks two things: unlimited checks, and the ability for a position rule to change a keyword bid instead of only telling you about it.
Yes, and there is no card at any step. Checking a listing needs no account — five checks a session. A free account adds saved alerts on up to ten keywords or ASINs, and it does not expire or downgrade. Connecting an Amazon account makes checks unlimited. SellerMate earns on its ads automation platform, which is a separate product; the tracker stays free.
Everything checked here is public: the search results page and the product page, exactly as a shopper sees them. No account access, no private data, nothing behind a login. It is the same information you would get by searching manually, collected on a schedule instead of by hand.
Three to five. Beyond that the alerts stop being read, which is worse than not having them. Pick the ASINs that appear next to yours in the search results for your best keyword rather than the biggest names in the category — the category bestseller usually is not the listing taking your specific sales.
No, and neither can anyone else — those are not public. What you can see is price, star rating, review count, best-seller rank, availability, and where they sit in the search results. Any tool claiming exact competitor sales figures is estimating from the same public signals you can see here.
Yes, when the rule is about search position and you have connected an Amazon Ads account. A competitor climbing above you on a keyword can raise your bid on that keyword, within a ceiling you set and after a cooldown, and it asks before acting unless you turn that off. Price and rating rules on a competitor alert only — there is no single correct ad response to a rival discount, so we do not pretend there is.
Their coupon is your conversion drop.
