Does GLC manage hreflang tags?
No. Shopify manages hreflang tags based on your market domains and language settings. These tags help search engines show the appropriate language or regional version of a page.
Where to manage automatic hreflang tags
- In your Shopify admin, go to Online Store → Preferences.
- Under Social sharing image and SEO, find Automatic hreflang tags.
- Turn the setting on or off, then click Save.

Automatic hreflang tags are on by default
Keep this setting on if you rely on Shopify to generate hreflang tags. Turn it off only if your theme or another app already provides its own hreflang tags.
For more details, see Shopify’s guide to hreflang tags and the Shopify changelog announcement.
