Yes. Carry a category column on the catalog sheet and use selector mapping with conditional blocks in the template. A camera body row injects sensor and lens mount fields; a power drill row injects torque and battery fields. The template carries every block; selector mapping decides which ones render per row.

Leave the cell blank in the catalog sheet. Use Twig truthiness checks in the template so empty fields render nothing (no orphan label). The pattern keeps the visual layout clean for products that legitimately do not carry a given spec, without forcing the catalog to populate every column.

Yes. Carry columns for datasheet_url, brochure_url, cad_file_url, or any other asset reference in the catalog sheet. Tag mapping injects the right link per row. Updating one URL propagates to every product page that references the asset on the next cache flush.

Standardize at the sheet level: a weight column is always grams or kilograms, never both. If you need both metric and imperial, carry separate columns (weight_kg, weight_lb). Tag mapping treats the cell value as a string, so consistent input is the only way to get consistent output across the catalog.

Yes. SleekRank exposes every generated URL through its sitemap and noindexes the base template page automatically. Submit the sitemap in Search Console once; new SKUs added to the catalog start getting crawled after the next rewrite flush. The base spec template page stays out of the index.

Yes. Add the JSON-LD block to the base template once and inject row-specific values like name, brand, sku, gtin, weight, and offers through tag mapping. Each /specs/{slug}/ renders its own valid Product schema sourced from the corresponding catalog row, no manual schema edits per page required.

Carry a revision_date column on the catalog and display it in the page footer via tag mapping. If you need historical revisions, maintain a separate revisions sheet keyed by slug plus revision_id and render a changelog block via list mapping. The current spec stays clean; history lives in its own structured place.

Flag the row with a status column the page group filter respects, or set a discontinued_date and let the template render a discontinued banner. Removing the row entirely takes the URL offline; in that case set a 301 to a parent category page to preserve any inbound links the spec page accumulated.
