What we control inside PMax

Six controls that keep PMax honest for jewelers, end to end.

Performance Max defaults are written to spend your budget and obscure where it went. Run with the right controls it can be a strong prospecting engine; run on defaults it quietly bills you for sales you would have made anyway.

// 01

Brand exclusion

The single most important PMax control for an established jeweler. Without brand exclusion, PMax intercepts people already searching your name and claims the conversion as net-new. We exclude brand so PMax is measured on the new business it actually brings.

// 02

Asset-group structure

Asset groups organized by category and intent (engagement, anniversary, custom, repair) rather than one undifferentiated group. Structure is the only steering wheel PMax gives you, and most accounts leave it at the factory setting.

// 03

Feed quality for jewelry

PMax leans heavily on the Merchant Center feed. Metal, stone, carat, certification, price band, and clean GTIN handling for one-of-one pieces determine what PMax can surface. A weak feed caps the campaign no matter the budget.

// 04

Audience & search-theme signals

The signals worth feeding (real customer lists, high-intent search themes) and the ones that bias the model toward cheap, low-value traffic. We feed the former and starve the latter.

// 05

Placement & brand-safety exclusions

Account-level placement exclusions to keep spend off junk apps and irrelevant content, plus brand-safety controls. PMax will spend on garbage placements by default; we shut that off.

// 06

Real attribution, reconciled monthly

PMax reporting blends channels and inflates assisted credit. We reconcile against actual revenue and separate net-new from brand-harvested, so you see what PMax truly produced. We do not care about vanity metrics. We care about business growth.

Why PMax disappoints most jewelers

Performance Max is built to spend your budget and hide where it went.

Left on defaults, PMax does three predictable things to a jewelry account: it harvests your brand searches and reports them as net-new, it spends on cheap junk placements, and it blends every channel into one number you cannot pull apart. The owner sees a strong reported ROAS and flat actual revenue. The gap is brand traffic the jeweler already owned, repriced as a PMax win. Run with brand exclusion, real asset-group structure, a tuned feed, and honest attribution, PMax becomes a genuine prospecting engine. We run it that way, with the controls Google's defaults quietly leave off.

No junior account managers. No binding contracts. You own the Google Ads account, the feed, and the audiences when an engagement ends.

Straight answers

Questions jewelers ask before they apply.

Is Performance Max good for jewelry stores?

It can be a strong prospecting engine when run with controls: brand exclusion, deliberate asset-group structure, a tuned Merchant Center feed, and honest attribution. Run on defaults it tends to harvest brand traffic and report it as net-new, which flatters the dashboard without growing the business.

Why does Performance Max eat brand traffic?

Because by default it is allowed to serve against people already searching your name and then claims those conversions as its own. The fix is brand exclusion, which forces PMax to be measured on genuinely new business. Endico applies it on every account.

Should jewelers use Performance Max or Standard Shopping?

Both, deliberately mixed. Standard Shopping gives visible bid control over high-intent SKU queries; PMax adds automated cross-channel prospecting. Endico carves them out so they do not cannibalize each other.

How do you measure Performance Max results for a jeweler?

By reconciling PMax's blended, assisted-inflated reporting against actual revenue, and separating net-new sales from brand-harvested ones. That is the only way to know what PMax truly contributed rather than what it claimed.
