<b>ProductGroup is the variant fix most stores still aren't running</b>

Google shipped <code>ProductGroup</code> and <code>hasVariant</code> support to solve the duplicate-content mess that plagues color/size variant pages — and adoption is shockingly low.

The insider angle: without it, each variant URL competes as a separate Product, splitting reviews and ratings and confusing which page Google surfaces. With <code>ProductGroup</code>, you declare a parent entity, attach variants via <code>hasVariant</code>, and use <code>variesBy</code> to name the differentiating axes (color, size). Reviews can consolidate to the group.

What it means for you — if you run any catalog with variants, this is the highest-leverage markup change available; it directly addresses cannibalization the canonical tag alone can't. Watch this: shopping surfaces increasingly key off ProductGroup-level data.
