Enable the mobile viewport
Without a viewport tag, your site isn't responsive and Google's mobile-first indexing is impossible. It's one line to add.
Step by step
- 1
Add to <head>: <meta name="viewport" content="width=device-width, initial-scale=1">.
- 2
On a modern CMS (Shopify, Webflow, recent WordPress themes) it's often already there — check the page source.
- 3
If an old theme hides it, update it or edit the header template.
- 4
Test the mobile rendering (or the browser's responsive tool) to confirm.
Generalist method: adapt “depending on your tool” (WordPress, Shopify, Webflow, or directly in code).
