The most important item this week
PDP Schema markup for Product Variants (ecom)
Variant markup is how a catalog tells a machine that ten listings are one product in ten configurations rather than ten near duplicate pages. If an AI system reading the catalog cannot resolve that grouping, it has to guess from titles and images, which is how the wrong size, color, or price ends up in a generated answer, or how a brand gets described as having a thinner range than it does. The URL structure question is the practical edge here: a site whose variants live at path based URLs may be technically compliant with the schema but outside the preselection guideline, which affects whether the grouping is trusted at all. Anyone building a product catalog now is deciding URL structure before the markup goes on, and that decision is expensive to reverse.
