How to fix missing h1 on Squarespace

Steps for Squarespace

1. Open the page in the Squarespace Pages editor.
2. Click the text block that should serve as your main page heading.
3. Highlight the text, open the text format toolbar, and select **'Heading 1'** from the style dropdown. Squarespace outputs Heading 1 as `<h1>`.
4. For **Squarespace Commerce product pages**, the product title is automatically output as an H1 by the built-in product block — ensure the product has a clear, keyword-rich title under Commerce → Inventory → [product] → Title.
5. For **blog posts**, the post title field is automatically the H1 — make sure every post has a descriptive title.
6. Save/publish and verify using your browser's 'View Page Source' (Ctrl+U / Cmd+U) and search for `<h1>` to confirm it is present and contains the right text.

What is missing h1?

An H1 is the main heading on a webpage — the HTML tag that looks like `<h1>Your Page Title</h1>`. Think of it as the "headline" of a newspaper article: it tells both visitors and search engines what the page is about at a glance. Every meaningful page on your store — your homepage, collection/category pages, product pages, blog posts, and landing pages — should have exactly one H1. When that tag is missing, the page has no declared headline at all.

Google uses headings, especially the H1, as a strong signal to understand a page's topic and match it to relevant search queries — a missing H1 means you're leaving that signal blank and may rank lower for your target keywords. Shoppers scanning your page also rely on a clear headline to instantly confirm they've landed in the right place; without it, they're more likely to bounce, costing you sales. Screen readers used by visually impaired customers depend on H1 tags for navigation, so a missing H1 creates an accessibility barrier that could expose you to legal risk in jurisdictions with accessibility laws (e.g., ADA, EAA). Fixing missing H1s is one of the highest-ROI on-page SEO tasks because it's quick to implement and the impact on rankings and user experience is immediate.
