The working product
Qubba maintains a publication dataset and generates the public catalog from it. Each record includes a publication name, market, topics, price, turnaround and supplier label information. The full table is present in the HTML, so the publication list does not depend on an API request to appear.
From records to a usable interface
The same records supply price tiers, featured publications, filters and the order builder. Visitors can search by publication or topic, narrow the market and price tier, and add available publications to a proposed order. Volume discounts follow the stated five, ten and twenty article thresholds.
What you can verify
Open the catalog, filter it, compare prices and add titles to inspect the quote. These are visible product functions. They establish that the catalog and interface exist; they do not establish client revenue, publication outcomes or search performance.
Where supplier data stops
DA and DR are third party domain metrics. Dofollow, Indexed and AI source flags are unverified supplier reports about publishers. They do not guarantee a future article’s indexing, ranking credit or citations. Markets include both countries and regional categories.
Fulfilment and limits
The listed placement includes writing, one revision, publication and proof by live URL. Availability and the final scope are confirmed before invoicing. Paid placements require appropriate advertising disclosure and sponsored or nofollow link qualification. No label is a supplier category, not an exemption from disclosure.
Why this example matters
The catalog shows how Qubba structures data, publishes source-visible information and connects a selection interface to a business workflow. It is our own product example, not an invented customer story or a benchmark for every project.
