- Task
- Evaluate how a catalog created at the level of size and color will behave in product advertising.
- Solution
- OpenCart 3, a site map with an index of 42 sub-maps, full product markup on the card. GTM, GA4 and Google Ads are connected with the transfer of the product ID to remarketing.
- Result
- Measurement 08/01/2026: 115,456 product items, confirmed by two independent methods with a discrepancy of 2.4%. It's the SKU itself, not the model - the slugs show 80B, 75E, XL, 36-41, so without a grouping field, a dozen cards of the same model go to one show. A defect we found critical for product advertising: a sample of 150 product sitemap addresses yielded 50 redirects, and all 50 led to a different size or color; on the scale of the directory, this is about 37,000 addresses.
