In Episode 51 of TACOS Tuesday, Hamish Conway and Sebastian Hargreaves unpack three revealing insights from their Amazon ads audits - insights that could be quietly draining your budget and holding back your growth. Drawing on data from dozens of brands and millions in ad spend, they explore how many sellers lean too heavily on Sponsored Products while underusing high-potential ad types like Sponsored Display, the hidden risks of over-investing in branded search terms that can cannibalise your own sales, and the often - overlooked problem of wasted ad spend across broad, phrase, and auto targeting. They also share benchmarks to help you measure whether your ACOS and ad efficiency are truly competitive, and practical ways to reallocate your budget for stronger returns. Tune in to find out how your performance stacks up, and how small strategic shifts can lead to big gains on Amazon.
