How to fix document title on WooCommerce

Steps for WooCommerce

1. Install and activate the Yoast SEO or Rank Math plugin if not already present.
2. For Yoast SEO: go to SEO → Search Appearance → Content Types and set the title template for Products, Categories, and Pages using variables like `%%title%% – %%sitename%%`.
3. For individual products: open the product edit screen → scroll to 'Yoast SEO' (or 'Rank Math SEO') meta box → 'SEO title' field → enter/edit the title.
4. For pages/posts: same meta box on each edit screen.
5. If managing titles directly in the theme: edit `header.php` in your child theme (Appearance → Theme File Editor) and ensure `<title><?php wp_title('|', true, 'right'); ?></title>` or `wp_head()` is present inside `<head>`.
6. Never edit the parent theme directly — always use a child theme or the plugin's template override.

What is document title?

Every web page must have a `<title>` tag inside its `<head>` section — a short line of text that names the page. It's what appears in the browser tab, in screen-reader announcements when the page loads, and as the blue clickable headline in Google search results. A "missing document title" finding means at least one of your pages either has no `<title>` tag at all, or the tag is completely empty (e.g. `<title></title>`). This violates WCAG 2.4.2 (Level A), which is the most basic level of accessibility compliance.

For shoppers using screen readers or keyboard navigation — including many people with visual, motor, or cognitive disabilities — the page title is the very first thing announced when a new page loads. Without it, they have no quick way to know where they are, making your store confusing or unusable and exposing you to accessibility legal risk (ADA, EAA, and similar laws). For SEO, the `<title>` tag is one of Google's strongest on-page ranking signals and is the text Google most often uses as your search snippet headline — a missing or empty title can directly suppress your organic traffic and click-through rate. It also hurts conversions because customers lose trust in a store whose browser tab shows a blank or URL-only title.
