Data for journalists
RivalSweeper reads the public pages, ads and emails of the fashion, beauty, jewelry and home stores it monitors every day and keeps the dated history. A reporter can ask the RivalSweeper press desk for a number from that history and quote it, with attribution, by the deadline.

What RivalSweeper can give a reporter on request
Dated, per-category numbers across the stores RivalSweeper monitors, each with its as-of date and the sample size it is out of. RivalSweeper names no store or brand in what it hands out: aggregates and anonymized examples only.
Promotions and coupons
Homepage banners, promo bars and pop-ups, coupon codes and sale pages, as RivalSweeper reads them on the store.
Discount depth
The share of products showing a "was" price and the markdown from it, store by store, the way the RivalSweeper Discount Check reports it.
Price moves
Price changes on supported product pages, with the date RivalSweeper recorded each change and the price before it.
Product launches
New products and categories RivalSweeper found on a store, with the day they appeared.
Meta and Google ad activity
Facebook and Instagram ads from Meta's public ads tool (text, landing page, EU and UK reach), and Google ads activity; RivalSweeper does not read Google ad text.
Ask for a number
- Email [email protected] with the question and the deadline.
- The RivalSweeper press desk answers within one working day with the number, the as-of date and the method, or says that RivalSweeper does not have it.
- Every number RivalSweeper sends is quotable with the attribution "according to RivalSweeper".
RivalSweeper does not send estimates: a number is either read from the stores on a date, or not sent.

How RivalSweeper measures
RivalSweeper checks the public pages of each monitored store daily: the homepage, product and sale pages, plus public ads and the marketing emails the store sends.
RivalSweeper reports what it read on a date, never an estimate; between two checks a price is taken as unchanged, and a change is dated when RivalSweeper records it.
Every line RivalSweeper publishes carries its date and what it is out of, and no store or brand is named.
How to cite
One line, with the page title, the as-of date and the URL, so a reader can find the same number:
