Phone case and accessory compatibility search

Accessory buyers search by their exact phone model, and a case that fits the wrong size is a return. Atomz writes device compatibility into structured fields so a case, screen protector, or charger surfaces only for the devices it fits.

Result, your product is the answer

Every word in the question maps to a structured attribute, so the right product is the answer.

The problem

Why keyword search misses this.

Device fit is exact, and keyword search is not. It cannot tell a 15 Pro from a 15 Pro Max, which are different sizes, so a shopper searching their model sees cases that will not fit, buys one, and returns it. The near-miss is worse than no result, because it costs a return and a refund.

What goes in, what matches

The fields that answer the search.

The left column is what a shopper types. The right is the structured field Atomz writes to your metafields, the thing search and an agent match on.

How Atomz does it

Written once, to fields you own.

Atomz writes the exact devices an accessory fits, and the close models it does not, into your Shopify metafields, so search and the assistant return only the accessories that fit the device a shopper names and quietly exclude the look-alikes.

Everything lives in your Shopify metafields, so the same data powers your on-store search, your AI Assistant, and the off-site agents that read Shopify Catalog.

Phone case compatibility: questions merchants ask

How does it avoid the Pro vs Pro Max mix-up?+

Each accessory carries the exact devices it fits and the close ones it does not, so a 15 Pro Max search never returns a 15 Pro case, which is the most common and costly accessory return.

Can shoppers filter for MagSafe or other features?+

Yes. Features like MagSafe are their own fields, so a shopper can combine the device and the feature in one search.

Does this reduce returns?+

It targets the main cause of accessory returns, which is buying for the wrong but similar model, by making fit an exact match instead of a guess.
