How the catalog works
Open Web Catalog publishes stable, human-readable collections of public web addresses.
Public records
Each report contains a fixed set of public HTTP or HTTPS addresses supplied for a catalog batch.
Catalog ingestion validates address syntax and obvious local destinations, but does not fetch or DNS-resolve submitted destinations.
Reports remain available at stable URLs so changes in discovery and crawler activity can be observed over time.
Measurement
Server requests are recorded with sensitive headers removed. Suspected Google crawler visits are verified using network evidence before they are counted.
A listing documents inclusion in the catalog; it does not promise crawling, indexing, ranking, availability, or endorsement of the destination.
Publication controls
Draft reports are reachable only by their unlisted address. Published reports are added to catalog navigation and the XML sitemap.
