Review schema markup, on paid plans

Paid widgets add schema.org Review and AggregateRating JSON-LD to the page they sit on, so search engines and AI answer engines can read your Google reviews as structured data. Google does not show review stars for reviews a business shows about itself, so the gain is readability, not stars. The free plan shows the reviews without the schema. See how the schema works

iFrame is the universal fallback. Pick a CMS-specific guide if you'd rather use the recommended script embed.

Why Use the iFrame Embed for OpenTable Reviews?

OpenTable's official widget only books tables — it never shows reviews. The iframe approach works wherever HTML is allowed — including the places scripts can't run.

Bypasses Script-Stripping CMSes

Locked-down enterprise CMSes and intranet portals strip <script> tags by policy. The iframe is a static HTML element — it always survives. SharePoint, ServiceNow, WordPress.com Free, custom IT-locked CMSes.

Shows the Reviews OpenTable's Widget Won't

OpenTable's official website widget only takes reservations — it never displays reviews. BlooTrue's iframe-direct URL is the only OpenTable-review-display option for script-restricted hosts (and one of very few even on hosts where scripts work).

No OpenTable API Key Required

Works with any public OpenTable restaurant page. No developer application, no API quotas, no restaurant-level claim. Just paste your https://www.opentable.com/r/your-restaurant URL into the BlooTrue builder on this page.

Same Renderer as Script Embed

The iframe URL is the same endpoint the script loader mounts internally. Pixel-identical OpenTable review output — same theme, same styles, same data refresh cadence.

How Do I Embed OpenTable Reviews via iFrame?

Four steps. The only manual bit is extracting your widget ID from the standard snippet.

Build Your Widget and Get the Embed Code

Use the BlooTrue builder on this page. Paste your OpenTable restaurant page URL (e.g. https://www.opentable.com/r/your-restaurant), pick a style, then click Get Embed Code below to grab the standard snippet.

You only need a single value out of that snippet — the widget ID. Step 2 covers it. No OpenTable API key required.

Pull the Widget ID Out of the Snippet

Read the snippet — your ID is the part after blootrue-widget- in the <div> class.

Example — given class="blootrue-widget-abc123", the ID is abc123. Copy just that string.

Replace the Snippet with an iFrame Tag

Replace the standard <script> + <div> snippet with this iframe instead:

<iframe
 src="https://api.blootrue.com/api/widgets/embed/YOUR_ID/render"
 style="border:0;width:100%;min-height:600px;"
 frameborder="0"
 title="Reviews">
</iframe>

Swap YOUR_ID for the ID you grabbed in step 2. The iframe URL is the same endpoint the script loader mounts internally — same OpenTable widget, just a different mount strategy.

Paste the iFrame Wherever You Can Write Raw HTML

Paste the iframe wherever you can write raw HTML — locked-down CMSes, SharePoint web parts, ServiceNow content blocks, Notion HTML embeds, headless CMS rich-text fields, intranet portal pages.

Heads-up: iframe mode loses auto-resize, so set min-height generously. 600–800px is typical for OpenTable widgets — pick the higher end for Grid or Masonry styles. If you set min-height too low you'll see internal scrollbars in the widget.

Reviews still auto-sync from OpenTable every 24 hours.

Where Does iFrame-Only Embed Make Sense for OpenTable?

Whenever the host environment strips <script> tags. OpenTable's official widget only books tables — it never shows reviews — so the iframe URL is the only review-display option in these cases.

Locked-Down Enterprise CMSes

IT departments often configure CMSes to strip <script> tags as a baseline security policy. Iframe always survives the filter — and there's no OpenTable first-party review fallback that works there at all.

SharePoint and ServiceNow Intranets

Intranet portals frequently block third-party scripts via Content Security Policy. They typically allow iframes via a dedicated "Embed" or "Page Viewer" web part. Paste the iframe URL there directly — handy for restaurant-group intranets showcasing each location's diner ratings.

WordPress.com Free Plan

WordPress.com on the Free plan strips inline scripts. Self-hosted WordPress.org has no such restriction. If your restaurant's site is on WordPress.com Free, the iframe embed is the only path to displaying OpenTable reviews.

URL-Only Embed Slots

Notion, some wikis, and headless CMSes whitelist embeds by domain rather than by script. The iframe URL pastes directly into their "Add an embed" or "Embed URL" field — no HTML editing required.

HTML Newsletters and Email Signatures

Most email clients strip both scripts and iframes, but some preserve iframes (HubSpot signatures, certain Apple Mail templates). When iframes survive, BlooTrue's iframe is the only OpenTable-review-display option that works in that channel.

Compliance-Strict Environments

Hospitality groups, hotel-restaurant sites, and government-adjacent venues that audit every <script> on a page often prefer iframes because the JavaScript surface area is fully sandboxed. Easier security review, fewer audit exceptions.

OpenTable Review Widget for iFrame — Universal Embed for Script-Restricted Environments

BlooTrue's OpenTable Review Widget for iFrame is a free embed for environments that don't allow <script> tags — locked-down CMSes, intranet portals, email-style HTML, and any platform that strips JavaScript loaders. It's the universal escape hatch when the standard script embed is blocked. For OpenTable specifically this matters more than for most other sources: OpenTable's official website widget only takes reservations — it never displays reviews — so on script-restricted hosts there is no OpenTable-shipped option that puts verified-diner feedback on your page. The iframe approach works wherever HTML is allowed. Common targets: locked-down enterprise CMSes that strip <script> tags as a security policy; email signature platforms (HubSpot, Apple Mail templates) where iframes sometimes survive but scripts almost never do; intranet portals like SharePoint and ServiceNow CMS where IT blocks third-party scripts; the old WordPress.com Free plan (which strips scripts); platforms with a "URL-only" embed slot like Notion, some wikis, and headless CMSes that whitelist by domain; and HTML newsletters where the recipient's email client strips scripts but preserves iframes.

Same renderer, different mount point

The iframe URL https://api.blootrue.com/api/widgets/embed/YOUR_ID/render is the same endpoint the standard <script> loader mounts internally. iframe mode renders the exact same widget, just without the auto-resize and the script-driven mounting. Tradeoff: simpler integration, fixed height (you setmin-height manually). Visually pixel-identical to the script-embed output.

Why doesn't OpenTable have a review iframe embed of its own?

OpenTable's embed strategy is built around bookings: its official website widget takes reservations and nothing else. It does not publish a paste-ready review widget the way Google publishes Place Cards — and it doesn't publish a direct review-iframe URL either. Third-party widgets are the only way to surface OpenTable verified-diner reviews on your own pages. BlooTrue's iframe-direct mode is the free option in that category, and the only one that works on script-restricted hosts.

About OpenTable reviews in this widget

Your OpenTable widget shows the diner reviews from your restaurant's OpenTable page, the one at opentable.com/r. The score heading the widget is the overall star rating and review count OpenTable reports for that page, rather than a number built from the cards. Every review comes from a diner who booked through OpenTable and honoured the reservation, so nobody who did not sit down at your tables can post one. OpenTable's own website widget only takes reservations; pasting it in the hope of seeing diner reviews gets you a booking form, since OpenTable has no review embed.

Frequently Asked Questions

I already have the OpenTable reservation widget on my site, does it show reviews too?

No. OpenTable's reservation widget takes bookings and offers no way to show diner reviews. The BlooTrue widget is a separate one-line embed built from your opentable.com/r restaurant URL, showing the reviews diners left after honouring a reservation, with the OpenTable rating and review count in the header taken from your page.

Are OpenTable reviews worth embedding if diners can only review after a reservation?

Yes, because that rule is what sets OpenTable apart. OpenTable only opens the review form to a diner who honoured a reservation booked through OpenTable, so every card on your site comes from a person who ate at your restaurant on a known date. Sites that let anyone post cannot say that about their reviews.

How quickly does a new OpenTable review reach my website?

On a paid plan, by the next day: the widget refreshes from your OpenTable page every 24 hours, so a review written after last night's reservation appears the following day, and the BlooTrue badge is removed. On the free plan the diner reviews are the ones imported when you first published the widget; new ones do not arrive.

Why use the iframe embed for OpenTable instead of the standard script embed?

Use the iframe embed when the host environment strips <script> tags. The standard script loader is the recommended path because it auto-resizes and mounts inline. But on locked-down enterprise CMSes, SharePoint, ServiceNow, WordPress.com Free, intranet portals, and HTML newsletters, scripts get stripped as a security policy. For OpenTable specifically this matters even more: the official OpenTable widget only takes reservations — it never displays reviews — so there is no first-party fallback for showing diner feedback. BlooTrue's iframe-direct mode is the only path on those hosts. The iframe URL is the same endpoint the script loader mounts internally, so the widget itself is identical.

What environments require the iframe-only embed for OpenTable?

Common ones include: locked-down enterprise CMSes that strip <script> tags as a security policy; SharePoint and ServiceNow intranet portals where IT blocks third-party scripts; the WordPress.com Free plan; Notion and other headless CMSes that whitelist embeds by domain; some wikis that allow only iframe URLs; and HTML newsletters where the recipient's email client preserves iframes but strips scripts. Since OpenTable's own widget only books tables and never shows reviews, BlooTrue's iframe-direct is the only realistic path to displaying diner reviews on these hosts.

Does OpenTable offer its own iframe embed widget for reviews?

No. OpenTable's official website widget exists, but it only takes reservations — it does not display reviews, as a script or as an iframe-direct URL. BlooTrue's iframe URL fills that gap: it pulls verified-diner reviews from any public OpenTable restaurant page and renders them inside an iframe that pastes anywhere HTML is allowed.

Do I need an OpenTable API key or developer access?

No. BlooTrue works with any public OpenTable restaurant page — no OpenTable API key, no developer application, no restaurant-level claim required. Just paste your https://www.opentable.com/r/your-restaurant URL into the BlooTrue builder and BlooTrue pulls your real verified-diner reviews from the public page.

How do I find my widget ID after generating an embed code?

Generate the standard embed code in the BlooTrue builder, then read the <div> class. Your ID is the part after blootrue-widget- — for example, in class="blootrue-widget-abc123" the ID is abc123. Copy that string into the iframe src URL: https://api.blootrue.com/api/widgets/embed/abc123/render.

Can I auto-resize the iframe to match the widget content?

No — and this is the main tradeoff of iframe mode. Cross-origin iframes can't communicate their natural height back to the parent page without postMessage, and most script-restricted environments also strip postMessage handlers. So you have to set a manual min-height on the iframe. For OpenTable review widgets, 600–800px is a reasonable default. If you need true auto-resize, use the standard script embed instead.

Does the iframe embed have the same SEO benefits as the script embed?

No — and this is a meaningful tradeoff. The schema.org Review and AggregateRating JSON-LD lives inside the iframe document, not on the host page. Google does not bubble schema from a cross-origin iframe up to the parent page, so star rich snippets won't fire on the host URL via the iframe embed. If you need rich snippets on the host page, use the standard script embed — it injects the JSON-LD directly into the host page's DOM. The iframe embed is purely a visual display option for environments where scripts aren't allowed.
