Which Shopify product content terms should every merchant know?

Alt text

A short written description of an image, stored in the image’s alt attribute. Screen readers read it aloud, and search engines use it to understand what the image shows.

Answer engine

An AI system, such as ChatGPT, Perplexity or Google AI Overviews, that replies to a question with a written answer instead of only a list of links.

Answer-first copy

Writing that states the direct answer or key fact in the first sentence or two, before supporting detail, so readers and AI systems can quote it.

Breadcrumb

A navigation trail such as Home › Collection › Product that shows where a page sits in the site. BreadcrumbList schema can show it in search results.

Bulk editor

Shopify’s spreadsheet-style admin view for editing a field, such as price or SEO title, across many products at once.

Canonical tag

A link element that tells search engines which URL is the main version of a page. Shopify adds canonical tags automatically, for example when a product is reachable through several collection URLs.

Collection

A group of products in Shopify, either manual or automated by conditions such as tag or product type. Collection pages are important category landing pages for SEO.

Compare-at price

The original price shown crossed out next to a lower sale price in Shopify. It should reflect a real previous price.

The share of sessions or visitors that end in a purchase. Product page conversion is often measured alongside add-to-cart rate.

The URL-friendly part of a Shopify product or collection address, such as merino-crew-sweater in /products/merino-crew-sweater.

Hreflang

Indexing

A search engine adding a page to its database so it can appear in results. Google Search Console shows which pages are indexed.
