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

Why Use BlooTrue for OpenCart?

The fastest way to put Google reviews on your OpenCart storefront — no marketplace extension, no PHP edits, no recurring fee.

Unlimited Widget Views

Unlimited widget views on every plan, free included. Display your Google reviews to OpenCart shoppers — paid OpenCart marketplace extensions cost $20–$60 each; BlooTrue's free plan never throttles your widget.

No Marketplace Extension Required

Pure HTML embed. No vQmod / OCMOD patch, no PHP file edits, no theme override. Pastes into the core CMS Information system or the bundled HTML Content module that ships in OpenCart 3.x and 4.x.

Works on OpenCart 3.x and 4.x

Same install path on both major versions. The Source toggle in the editor and the HTML Content module from Extensions → Modules exist in core on both 3.x (still dominant) and 4.x.

Auto-Sync With Google

New Google reviews appear on your OpenCart store automatically every 24 hours. No manual refresh, no cron jobs, no admin work.

How Do I Install BlooTrue on OpenCart?

Takes less than a minute. No coding, no extension purchase, no PHP file edits.

Decide Where The Reviews Go

Log into your OpenCart admin and decide where the Google reviews should appear:

A static Information page (About Us, Reviews, Testimonials) — found under Catalog → Information.
A sidebar or footer module using the bundled HTML Content module — assigned via Design → Layouts.

Most OpenCart merchants pick a Reviews Information page. If you want the widget on every page, the HTML Content module is the right path.

For a CMS Page: Catalog → Information

In the OpenCart admin, open Catalog → Information, then edit (or create) the target page. In the rich-text editor toolbar, click the Source button (looks like </>) to switch from WYSIWYG to raw HTML view.

Paste the BlooTrue embed code there. This step is critical — if you paste in the visual view instead, OpenCart sanitizes the<script> tag and the widget disappears on save.

Save the page. Visit the storefront URL of that Information page — your Google reviews are live.

Or Use the HTML Content Module

For sidebar / footer / homepage placement, open Extensions → Modules, find HTML Content (it's a core module — already installed in OpenCart 3.x and 4.x), click Add Module, give it a name like "Google Reviews", click the Source button in its editor, and paste the embed code.

Click Save. The module is created but not yet visible.

Assign to a Layout and Publish

Open Design → Layouts, pick the layout you want to target (Home, Default, Product, Category, etc.), and add the newly-created HTML Content module to a position — Column Left, Column Right, Content Top, Content Bottom, or Footer.

Save the layout. Refresh your storefront — the Google reviews appear in the assigned position.

Reviews auto-sync from Google every 24 hours — no further OpenCart maintenance needed. Works identically on OpenCart 3.x and 4.x.

Google Review Widget for OpenCart — Free, No Extension Needed

BlooTrue's Google Review Widget for OpenCart is a free, extension-free embed that displays your Google reviews on any OpenCart storefront. OpenCart is a free, open-source PHP e-commerce platform widely used in MENA, Eastern Europe, and South-East Asia, and it ships with both a CMS Information system (Catalog → Information) and a bundled HTML Content module (Extensions → Modules). BlooTrue pastes into either — no PHP edits, no vQmod / OCMOD patches, no marketplace extension purchase. Works on OpenCart 3.x (the dominant deployed version) and OpenCart 4.x with any theme. The single biggest install gotcha is the Source button (the</> toggle that switches the editor between WYSIWYG and raw HTML) — without clicking it, the visual editor escapes the embedded <script> tag and the widget disappears on save. 100+ widget styles (slider, marquee, grid, list, masonry, badge, compact badge) with light and dark themes plus a custom color picker. On paid plans, schema.org Review + AggregateRating JSON-LD is added to the page where the embed runs inline rather than inside an iframe, so search engines and AI assistants can read the reviews as structured data. Google does not show review stars for reviews a business shows about itself, so the gain is readability, not stars.

Does BlooTrue work on every OpenCart version?

Yes. BlooTrue works on OpenCart 3.x and OpenCart 4.x. There is no minimum version because the widget is pure HTML — OpenCart allows custom HTML in CMS pages and HTML Content modules on every install, and BlooTrue does not need any server-side hooks or PHP file edits.

BlooTrue vs paid OpenCart marketplace extensions

The OpenCart marketplace lists multiple Google-reviews extensions priced from roughly $20 to $60 each (one-time or yearly). They typically wrap the same public Google data BlooTrue uses, and many require vQmod or OCMOD patches that conflict with theme upgrades. BlooTrue is free, has no view cap, and pastes into the core CMS Information system or the bundled HTML Content module — no patching, no theme conflicts, no recurring fee.

About Google reviews in this widget

Your Google widget shows the reviews on your Google Business Profile, and the number above the cards is the Google rating and review count as Google reports them, not an average of the cards. Anyone with a Google account can rate you from Maps or Search, no purchase needed. Google offers no review embed and the Business Profile has no widget, so pasting a Maps embed gives owners a map, not reviews. The free plan keeps the 4-star-and-up Google reviews imported at creation; a review left on Maps next week needs a paid plan's daily refresh.

Frequently Asked Questions

Why does the rating in my Google widget not match the average of the reviews it shows?

Because the header number is what Google publishes for your Business Profile, not a figure BlooTrue works out from the cards. The free plan shows only your 4-star-and-up Google reviews, so averaging those cards would give a higher number than Google does. Keeping Google's rating and count means visitors see the figure from Maps.

Can I get an embed code for reviews from my Google Business Profile?

No. The Business Profile gives you a link for asking customers to review you, but no embed code and no widget. The BlooTrue builder finds your profile when you type the business name, city and country, then hands you a one-line embed to paste into your website with no plugin, in about a minute.

Will embedding Google reviews put star ratings under my site in Google search?

No. Google's review-snippet rules exclude reviews a business shows about itself through an embedded widget. A paid widget still emits schema.org Review and AggregateRating JSON-LD carrying your Google rating, and that markup reaches your page when the builder renders the embed inline rather than in a sandboxed iframe, so search engines and AI assistants can read your reviews as structured data.

Is the BlooTrue Google review widget free for OpenCart?

Yes. BlooTrue is completely free for OpenCart. No marketplace extension purchase, no recurring license fee, unlimited widget views, no credit card. The free plan shows your Google reviews with BlooTrue branding in the footer; paid plans remove the branding and unlock more widgets.

Do I need to buy an OpenCart extension to display Google reviews?

No. The OpenCart marketplace lists paid Google-reviews extensions priced from roughly $20 to $60 (one-time or yearly), but BlooTrue does not require any extension. The embed pastes directly into a CMS Information page or the bundled HTML Content module — both ship in core OpenCart 3.x and 4.x.

Why does my embed code disappear after I save the OpenCart page?

Because you pasted into the WYSIWYG (visual) editor, which strips or escapes the <script> tag. Click the Source button (looks like </>) in the editor toolbar to switch to raw HTML view, paste the embed code there, and save. The Source toggle is the #1 install gotcha on OpenCart — without it, the editor sanitizes the script.

Does this work on both OpenCart 3.x and OpenCart 4.x?

Yes. The embed is pure client-side HTML and JavaScript and the install path (Source toggle in the editor, HTML Content module from Extensions → Modules) exists in both major versions. OpenCart 3.x is still the dominant deployed version; OpenCart 4.x is supported equally.

Where exactly should I paste the embed code on OpenCart?

Two paths. (1) For a static page (About, Reviews, Testimonials): Catalog → Information → edit the page → click the Source button (</>) in the editor → paste. (2) For sidebar/footer placement: Extensions → Modules → install HTML Content → edit it → click Source → paste → assign to a layout position via Design → Layouts.

Will the widget slow down my OpenCart store?

No. The widget loads asynchronously after page content, so it never blocks rendering. The script is under 20KB, reviews are served from a CDN cache, and lazy loading defers any image fetches until the widget enters the viewport. Typical impact on Largest Contentful Paint is under 50ms — well within Google's Core Web Vitals thresholds.

Will the embedded reviews help with OpenCart SEO?

Yes. BlooTrue auto-injects schema.org Review and AggregateRating JSON-LD on every page that loads the widget, so search engines and AI assistants can read the reviews on your OpenCart product, category, and Information pages as structured data. This works on top of any product schema your OpenCart theme already emits.
