The snippet is ordinary HTML, so it works anywhere you can add HTML. The catch is that several editors offer a block that shows code rather than running it, and picking the wrong one fails silently — your visitors see the snippet as text.
WordPress (block editor / Gutenberg)
Add a Custom HTML block and paste the snippet into it. Do not use the Code block — it exists to display code on the page, so your snippet will appear as text and no widget will load. Preview won’t always run the script; check the published page.
WordPress (Elementor)
Drag in the HTML widget and paste the snippet there. Rich-text widgets such as Text Editor are not a reliable home for a script tag — use the one meant for HTML.
WordPress (classic editor)
Switch from Visual to the Text tab before pasting. The visual tab is a rich-text field and will not run the snippet.
Anything else
Paste it into the page’s HTML where the reviews should appear — a raw-HTML block, a template file, or a theme section. If your site builder offers an “embed” or “custom code” block, that is the one.
How confident we are, per platform: the block-editor behaviour is something we hit ourselves on a live site. The Elementor and classic-editor notes follow the same principle, but we have not re-verified each editor, and Shopify is absent rather than guessed. If yours behaves differently, message us and we will walk it with you and write it up here.
