ENDICO DATA STRATEGIC JEWELRY · LUXURY NEW YORK CITY EST. MMXXV

The growth engine
fine jewelers never had.

Fine jewelry and luxury pieces are bought over weeks, on trust. Generalist agencies run one ecommerce playbook for every store, and results swing. We run your Meta, Google and Pinterest ads, website, AEO and SEO, and retention as one system built for that decision. We do not work with two jewelers in the same trade area.

WHY US · I

Why work with us.

Built for luxury · The founder on your account · Yours to keep

Built for how luxury is bought

An engagement ring or an anniversary piece is decided over weeks, with trust on the line. We plan the ads, the site and the follow-up around that decision, not around a one-day sale.

The founder runs your account

We never pass you on to a junior account manager. The person on your first call builds the campaigns, reads the numbers and makes the calls.

Yours to keep

You own everything. Every ad account, pixel, audience, creative file and the website stay in your name. No binding contracts: leave any time and take all of it.

HOW IT STARTS · II

How it starts.

45 minutes · A flat fee in writing · Yours from day one
STEP·I

Book 45 minutes with William

On Google Meet. Send your website first; he looks at it before the call.

STEP·II

Get a flat fee in writing

If your trade area is open, you leave scoping with a flat fee in writing, what it covers, and no obligation to take it.

STEP·III

Start in your name

Accounts are set up in your name from day one, and the work starts where the gap is largest.

THE FIT · III

Who we work with.

Jewelry · Luxury · Websites and AEO for almost anyone

A good fit

  • Fine jewelers and luxury product brands, run by an owner or the person who runs marketing, ecommerce or the website.
  • Best fit: a direct-to-consumer jeweler selling original designs.
  • Anywhere in the world, as long as we can work in English.

Probably not a fit

  • A jeweler in your trade area already works with us.
  • You compete directly with a luxury brand we already serve.
  • You need results by next week. We build for the long run. While we have had very quick results with many clients, it is an unrealistic expectation to get instant results, and we do not run with false promises.
  • Your ad budget is too small to give clear answers yet. We will tell you on the call.

We can work with almost any business that needs web development or SEO/AEO.

THE DIPTYCH · IV

The typical agency, and the opposite.

The Typical Agency

  • ✕Runs one ecommerce playbook for every store.
  • ✕Hands you to a junior account manager once you sign.
  • ✕Binding retainers that hold you whether it works or not.
  • ✕Keeps your ad accounts, pixels, and audiences hostage.
  • ✕Reports vanity metrics and the return the platform claims for itself.
  • ✕Signs your competitor the week after signing you.

THE GROWTH ENGINE · V

One growth engine.

All run end to end · By the founder
I

Advertising

Meta, Google, and Pinterest, run end to end.

Creative tested systematically, and budgets judged on what the store actually sold, not the return the platform reports about itself. You own the ad accounts, the pixels, and every audience we build.

II

Web Development

Fine jewelers deserve fine websites.

Conversion-first builds for fine jewelry: ring builders, ecommerce, redesigns, speed. Most jewelers treat their website like a brochure instead of a revenue-generating asset. We build the asset.

AEO & SEO

Get cited by ChatGPT and Google AI.

Buyers now ask the AI platforms who to trust. Structured data and clear answers on your site, so ChatGPT, Google AI and Perplexity can read, trust and cite you. Starts with the paid AEO + SEO audit and its findings.

Retention & Reputation

Email, SMS, reviews, and the second sale.

Journeys and review programs that bring buyers back for the anniversary, the upgrade, and the referral. Owned channels, tracked separately from acquisition, protecting the name you built.

STRAIGHT ANSWERS · VI

Before you book.

Cost · Contracts · Who does the work · The call
What does it cost?
Pricing is set after the scoping conversation, because a small estate jeweler and a multi-location bridal store should not pay the same. You leave scoping with a flat fee in writing, what it covers, and no obligation to take it. The AEO + SEO audit is the one product with a fixed price, shown at its intake.
Is there a contract?
No binding contracts. Stop any month and keep every account. Ad spend goes to the platforms, so we only take accounts we believe we can move.
Who runs my account?
William Endico, the founder: strategy, build, optimization and reporting. We never pass you on to a junior account manager.
What happens on the call?
45 minutes with William on Google Meet. Send your website first; he looks at it before the call. If your trade area is taken, you hear it first.
Is my trade area open?
We do not work with two jewelers in the same trade area. We check yours before we talk, and if it is taken, you hear it first.
Do you work with brands outside jewelry?
Yes. Luxury product brands get the full growth engine, and we will not work with your direct competitors. Every other business can hire us for a website or AEO and SEO.

★★★★★Google review · September 2026

I absolutely love working with Will and Endico Data Strategic, and I am so happy he found us! Over the years I have worked with a variety of digital marketing and ads teams. They have done a fine job, but used vanity metrics without any explanation to keep us on to maintain their retainers. They never deep dived into our business our customers to figure how to strategically make our ads and money work for us. When Will found us, I was so frustrated and felt like I was just throwing money away.. and in many ways I was. He is so thorough with the work he does and it's clear he's passionate about what he does, while taking great efforts to get us the results we're looking for. I look forward to working with Will and Endico Data Strategic long into the future and would recommend him to anyone looking who is looking for a high level of care and attention.
