Context and boundaries

WorkflowAI recommendations–Bid and placement optimization–PPC-team-designed automation–Keyword performance monitoring?
Implementation?From June 2024; individual metrics use disclosed windows
CaveatsDuplicate official blog URL; not independent proof.–Published date conflicts with the stated December 2025 endpoint.–The December 2025 overall-ACoS endpoint is chronologically impossible relative to the legacy article publication unless the page was silently updated or the year is a typo.–Vendor-hosted; no customer-owned confirmation.vendor_owned

Source trail

  1. Primebook case study

    Primebook reportedly went from zero to 100 Amazon orders within two weeks and then achieved 25% month-over-month order growth and 20% month-over-month sales growth. The page reports overall ACoS from 21% in July 2024 to 11% in December 2025 (about -47.6%), while the headline reports -57% for the keyword 'laptop' and +40% ad sales for that keyword. The legacy blog supplies the keyword endpoints 21% to 9% and visibility 0.75% to 2.5% through December 2024. The case publication chronology is inconsistent with its December 2025 endpoint.

  2. Primebook legacy blog case

    The blog duplicate reports zero to 100 orders in two weeks, 25% month-over-month order growth, 20% month-over-month sales growth, keyword 'laptop' ad sales +40% from July-December 2024, keyword ACoS 21% to 9% and top-of-search impression share 0.75% to 2.5%. It also reports overall ACoS 21% in July 2024 to 11% in December 2025 even though the post was published in February 2025, an impossible chronology unless the endpoint year is a typo or the page was altered without updating its date.
