Explore the benchmark

A few things,
before we talk.

What jewelers ask before they call.

Who do you work with?

Jewelry brands, watch brands, wholesalers, authorized retailers, custom jewelers, manufacturers and pre-owned watch sellers. If you have paid an agency before and never found out what the money sold, that is the conversation we are used to having.

How can I see what is happening with my marketing?

We agree on the measures of success at the start. Your client portal brings search and AI visibility, tasks, sales reporting, and website availability together. You can open it whenever you want to look. Our reviews use the same information you can see, and we explain what the numbers mean and where information is incomplete.

How much does it cost?

It depends on what you sell, how many locations you have and what needs doing. We do not publish fees. We agree the work and the price before anything starts, and ad spend and platform costs are separate and explained up front. Paid advertising starts at $5,000 a month in ad spend.

How long before we see progress?

Ads bring visits within a couple of weeks of going live. Search takes months, and we say so on the first call. Sales depend on your offer and on how long your customers take to decide, so we do not forecast a first-sale date. We set milestones and review inquiries and recorded sales as we go.
