Problem
Canes are bought by length and grip size, but the theme's size guide was built for clothing and showed model measurements. On the SEO side, filtered collection pages all looked the same to search engines, and app scripts slowed the first load.
Solution
I turned the size guide into two tabs, a cane length chart and a grip size chart, driven by a page chosen in the theme settings. Collection pages now build their title, heading and meta description from the active filters, and pages with three or more filters are kept out of the index. I added a setting that delays chosen app scripts until the visitor interacts, cleaned up breadcrumbs, and set a robots.txt template.
Key decisions
Chose a settings-selected size guide page over a per-product field
Why One cane length chart and one grip chart serve the whole catalogue, and the owner edits them as ordinary pages.
Chose to noindex deeply filtered collection URLs
Why Combinations of three or more filters create near-duplicate pages that dilute the pages worth ranking.
Chose a merchant toggle for script deferral
Why The owner can switch the optimisation off or list which app scripts to delay without touching code.
Results
- The product page shows a cane length chart and a grip size chart in a drawer.
- Collection titles and meta descriptions change with the chosen filters.
- Collection pages with three or more filters carry a noindex tag.
- App scripts can be loaded after first interaction, controlled from theme settings.
