Where the SEO fields live in the Shopify admin
Title tags live in two places per resource: the auto-generated theme template (which inserts the store name) and the Search engine listing > Page title override. Meta descriptions live only in the Search engine listing > Meta description field. URL slugs live in the resource editor (Product, Collection, Page, Blog post) under the URL handle field. Sitewide defaults — homepage title, homepage description, store name — live in Online Store > Preferences. Image alt text lives in the media library.
The Shopify title tag rule: 60 recommended, 70 max
Shopify's Adding keywords doc states: 'You can enter up to 70 characters in the title.' The recommendation is less than 60 characters because Google truncates titles at roughly 600 pixels, which usually corresponds to 50-60 characters. Themes auto-append the store name to the title, which eats character budget — a 60-character Page title becomes an 80-character full title in the rendered HTML.
The Shopify meta description rule: under 160 characters
Shopify's Adding keywords doc recommends meta descriptions under 160 characters. Google truncates at roughly 920 pixels in mobile (about 120 characters) and 990 pixels on desktop (about 158 characters). The 160-character recommendation accounts for desktop truncation. The bigger pattern owners miss: Google rewrites the meta description more often than the title, and the AI snippet engines (AI Overviews, ChatGPT shopping cards, Perplexity recommendation summaries) generate their own snippets from on-page content — your meta description is one signal among many, not the final SERP / AI surface text.
URL slugs on Shopify — products, collections, pages, blog
Shopify URL paths are fixed: /products/handle, /collections/handle, /pages/handle, /blogs/blog-name/article-handle. The handle is the editable slug. Themes auto-canonical the resource URL to the primary path. Changing a handle while the resource is published creates an automatic 301 redirect, which is one of the highest-value default behaviours in Shopify SEO. Image file names cannot be changed after upload — rename before uploading or replace the image.
Online Store > Preferences — the sitewide panel
Online Store > Preferences sets the homepage title tag, homepage meta description, store name (which themes auto-append to titles), social sharing image, Google Analytics ID, Facebook Pixel ID, and the storefront password. It is the single most important sitewide panel for SEO and the first one to configure on any new Shopify store. Shopify's SEO overview confirms the panel as the home for title-tag controls.
Grow SEO — Shopify's early-access AI suggestion tool
Grow SEO is Shopify's AI-driven SEO feature that generates 'AI-driven suggestions tailored to enhance short title tags and short descriptions' on product and collection pages. The verbatim limits per Shopify: max 100 suggestions, English only, not compatible with Hydrogen, product and collection pages only. The feature is in early access — 'available only to certain merchants' as of May 2026. It edits the search-engine-listing page title and the on-page description, not the meta description field.
The install order, field by field
The right order on a new store: (1) Online Store > Preferences first — homepage title, homepage description, store name, social image. (2) Resource-level Page title and Meta description on every product, collection, page, and blog post. (3) URL slugs reviewed and locked before publishing (slug changes after publish trigger redirects). (4) Alt text on every image via the media library. (5) Grow SEO enabled last, only if you have early access and 500+ products.
