Is there a free review widget for Kartra?

Yes — BlooTrue embeds Google, Facebook, Trustpilot, Yelp, TripAdvisor, G2, Capterra, Airbnb, Booking.com or any of 21 review platforms on Kartra for free. Add a Custom Code (HTML) component in the Kartra page builder. No plugin, no view caps.

Which review platforms can I show on Kartra?

21 platforms: Google, Trustpilot, Yelp, Facebook, TripAdvisor, Airbnb, Angi, Glassdoor, Agoda, BBB, OpenTable, RateMDs, Capterra, G2, Indeed, TrustRadius, Clutch, Expedia, Booking.com, Etsy, Google Play — each with its own Kartra install guide. Starter ($9/month) blends its 3 connected platforms into one all-in-one widget, and Pro ($29/month) and higher blend every platform you connect.

Do I need a Kartra plugin or app?

No. BlooTrue is a pure HTML embed — one line of code pasted into the Kartra editor. Add a Custom Code (HTML) component in the Kartra page builder.

Can I add a review widget to a Kartra sales page without a plugin?

Yes. Kartra has no plugin system for this and does not need one. Build the widget on BlooTrue, copy the one-line embed code, and paste it into a Custom Code (HTML) component in the Kartra page builder. After you save and publish, the sales page displays the reviews. Start to finish, it takes about a minute.

Does the review widget work on Kartra checkout pages as well as sales pages?

It does. Kartra checkout pages use the same page builder, so you add a Custom Code (HTML) component next to the payment form and paste the same embed code. Placing it under the order summary means buyers see third-party reviews at the moment they type in card details.

Do the reviews in my Kartra widget change when I get new ones?

On the free plan the widget keeps the set of reviews it collected on the day you created it, with no later additions. A paid BlooTrue plan pulls in new reviews once a day and takes the small badge off. Nothing changes inside Kartra either way; the Custom Code component keeps the same embed code.

How it installs on Kartra

1
Open the page in the Kartra page builder.
2
Add a component and choose Custom Code (HTML) where the reviews should appear.
3
Paste the BlooTrue embed code into the code area and apply.
4
Save and publish the page — the widget renders live.

Where the code goes on Kartra

Kartra holds the embed code in a Custom Code (HTML) component from the page builder's component list. The builder sandboxes some scripts in its preview, so the component may show a frame or nothing while you edit; the reviews render on the published page. The component follows the width of the column it sits in, and its height is whatever the widget needs. Kartra sales pages and checkout pages are separate pages, so a widget above the offer stack and one beside the payment form are two components, each holding the same code.

Where reviews earn their place on a Kartra site

Sales pages above the offer stack and on checkout pages near the payment form — proof exactly where money changes hands.

If the widget does not show on Kartra

A blank Custom Code component in the Kartra builder preview is the preview sandbox at work. Publish, then open the live page URL to check the reviews.
Make sure you chose Custom Code (HTML), not a text component. A Kartra text component prints the script as plain characters instead of running it.
Reviews on the sales page but missing at checkout? Kartra checkout pages are built separately, so drop a second Custom Code component beside the payment form.
