Yes, that is the core pattern. Keep ingredients in one sheet with one row each, then carry a per-list quantity column for each list. Chicken thighs appear in /shopping-list/weekly-meal-prep/ and /shopping-list/keto-starter/ from a single row, with each list reading its own quantity column.

Carry a base_quantity column on the ingredients sheet and a serving_size_multiplier on the lists sheet. Compute the displayed quantity in the template by multiplying the base by the list's multiplier. Updating a recipe to a new yield is one cell on the lists sheet.

Append a row to the lists sheet with slug, theme, serving_size, and notes. Fill the new list's per-list quantity column on the ingredients sheet for every ingredient it requires. After cacheDuration elapses or you clear the items table, /shopping-list/{slug}/ resolves and joins the sitemap on the next rewrite flush.

Yes. Carry a substitutions column on the ingredients sheet (or a per-list substitution column for diet-specific swaps). Selector or list mapping renders substitutions alongside the ingredient. Updating a substitution propagates across every list that includes the ingredient.

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

Yes. Carry a category column on the ingredients sheet (produce, dairy, pantry, frozen, meat). Run multiple list mappings in the template, one per category in aisle order. Shoppers walk the store once rather than backtracking, which is the practical reason categorized lists outperform flat ones.

Carry a price column on the ingredients sheet and compute totals in the template by summing prices across the filtered set scaled by quantity. Every list reads the same price cells, so updating a price in one place propagates across the cluster on cache flush.

Carry an available_seasons or in_stock column on the ingredients sheet and filter list mapping accordingly. When an ingredient is out of season, it drops off lists automatically, and the substitutions column surfaces the swap. Restore availability to bring it back across every relevant list.
