MerchentiaShopify glossary
Plain-English definitions of the storefront and app terms we use across these guides.
Announcement bar
A thin banner on a storefront used for promotions, free-shipping thresholds, flash-sale countdowns, or store notices. See Announcements.
Average order value (AOV)
The average amount a customer spends per order. Raising it — for example by cross-selling a full outfit — lifts revenue without needing new traffic.
App Store Optimization (ASO)
Improving an app’s Shopify App Store listing — title, subtitle, keywords, and recent review velocity — so it ranks for the searches merchants actually use.
Cumulative Layout Shift (CLS)
A Core Web Vitals metric measuring unexpected layout movement as a page loads. High CLS frustrates shoppers and can hurt search rankings, so storefront widgets should reserve their space.
Complete the look
A product-page widget that turns one photo into a shoppable outfit by surfacing the other items shown — also called “shop the look.” See Shop The Look.
Fit finder
An on-page tool where a shopper enters a few measurements and receives a recommended size for that specific product, so they buy one size instead of two. See Size Chart Fit.
Free-shipping bar
A progress bar showing how much more a shopper must add to qualify for free shipping — a simple nudge toward larger carts.
Geocoding
Converting a street address or place name into map coordinates (latitude and longitude) so it can be placed on a map. Results are usually cached to avoid repeat lookups.
Infinite scroll
A browsing pattern that loads more products automatically as the shopper scrolls, instead of clicking through numbered pages. See Infinite Scroll & Load More and our SEO-safe guide.
LocalBusiness structured data
Schema.org markup describing a physical location — name, address, opening hours — so search engines can show it in “near me” results.
Map tiles
The image or vector squares that make up an interactive map. Open or self-hosted tiles (built from OpenStreetMap data) avoid the need for a paid map API key.
Pagination
Splitting a collection across numbered pages with crawlable URLs. Search engines follow those URLs to reach every product, which is why keeping pagination as a fallback matters under infinite scroll.
SEO-safe
Built so search engines can still crawl and index your content — for example, keeping real paginated URLs as a fallback when you add infinite scroll, and changing no theme code.
Size chart
A table of garment or product measurements that helps shoppers choose the right size before buying. Per-product charts beat generic S/M/L labels. See Size Chart Fit.
Store locator
An interactive map and searchable list that helps shoppers find your stores, dealers, or stockists near them. See Store Locator.
Theme app extension (app block)
A Shopify app block merchants add from the theme editor on Online Store 2.0 themes — no code changes, and removed cleanly on uninstall. It’s the modern, SEO-safe way to add storefront features.
