Monitor Competitor Collections and Category Pages for Assortment Changes
A competitor's collection page reflects their current merchandising priorities. Beaconmon diffs the HTML on any collection or category page so you see when products are added, removed, or repositioned, and when catalog structure changes.

Collection and category page HTML monitoring
Add a competitor collection or category page URL and Beaconmon tracks every change to the rendered HTML: products appearing, products disappearing, item order shifts, and new section headings.
Featured product detection
When a competitor moves a product to the top of a collection or adds it to a featured section, the page diff surfaces the change. Consistent repositioning of the same product is a signal they are pushing it.
Collection structure tracking
Monitor a navigation page or collections index to catch when a competitor creates a new collection, renames one, or restructures their catalog hierarchy. Catalog reorganization often precedes a promotional push.
Works for any URL, any platform
Collection monitoring is HTML diffing on any page. Shopify collections, WooCommerce category pages, and custom category pages all work. No feed access required.

Frequently asked questions
What is collection monitoring and why does it matter?
A competitor's collection or category page reflects their merchandising decisions. Which products are featured, which are buried, and how collections are named all signal strategic priorities. Monitoring these pages gives you early visibility into assortment changes before they show up in your own analytics.
Does Beaconmon work for non-Shopify category pages?
Yes. Collection monitoring is HTML diffing on any URL. WooCommerce category pages, DTC site category pages, and any server-rendered collection listing work the same way. You add the URL and Beaconmon tracks changes to the page HTML.
How often should I check a competitor collection page?
Most teams use a 15 to 30 minute interval for collection pages. Collection changes are typically deliberate and infrequent, so shorter intervals add noise without adding useful signal. For high-velocity competitors during a sale period, a 5 minute interval may be worth it.
Can I monitor multiple collections per competitor?
Yes. Each collection page URL is a separate monitor. A typical setup might cover a main /collections/all page, one or two category-specific pages (such as /collections/sale or /collections/new-arrivals), and the site navigation if it is rendered in the page HTML.
How is collection monitoring different from Shopify product feed monitoring?
The Shopify product feed gives structured data about individual products: prices, availability, and product handles. Collection page monitoring captures what a competitor is surfacing to shoppers at the category level. Product feed and collection monitoring cover complementary angles and work well together.
