The Ad / iFrame Block

Readers skip ads on a web page. They can't skip one inside interactive content.

The Ad / iFrame Block places ad units and third-party embeds directly inside interactive content. Users are engaged, mid-flow, and paying attention. That's the placement advertisers can't get anywhere else.

No coding. Fully customizable. Brand-ready.

Why the Ad / iFrame Block works

Higher eCPMs, no clutter. Publishers report up to 20% higher eCPMs with in-quiz ads.

Attention you can't buy. Users inside a Quiz are mid-flow, engaged, and paying attention.

Works with your ad stack. Paste your ad tag straight into the block. No reconfiguration.

Any embed, anywhere. If it has an iFrame embed code, it works inside a Riddle block.

How to use the Ad / iFrame Block

In-quiz Ad / iFrame Block placing a display ad unit between two Quiz questions

In-quiz ad placements for higher eCPMs.

Place a display ad unit between questions where users are focused and mid-flow. In-quiz ad placements outperform standard display because users are actively participating rather than passively scrolling.

Programmatic ad tag pasted into the Ad / iFrame Block running inside a Riddle Quiz

Programmatic ad integration.

Drop your existing ad tags directly into the iFrame Block. Your programmatic setup runs inside the Quiz without any technical reconfiguration. Same ad stack, significantly better placement.

Sponsor creative and landing-page experience embedded via the Ad / iFrame Block in interactive content

Sponsor brand moments.

Use the iFrame Block to embed a sponsor's creative, video, or landing page experience directly inside your interactive content, delivering a full sponsor moment at the highest-attention point in the user journey.

Ad / iFrame Block embedding a third-party tool, map, or widget inside a Quiz

Third-party content embeds.

Embed any third-party tool, widget, or content experience via iFrame inside a Quiz or Poll. Maps, live scores, product configurators, booking tools. If it has an embed code, it works inside a Riddle block.

What is an Ad / iFrame Block?

An Ad / iFrame Block in Riddle Quiz Maker lets you place any ad unit or third-party embed directly inside a Riddle Quiz, Poll, personality Quiz, or minigame. It positions advertising at the highest-attention moments in your interactive content.

Why do in-quiz ads outperform standard display?

Users inside a Quiz are focused and actively participating, not passively scrolling. That context produces stronger ad recall and better performance. Publishers using Riddle's in-quiz ad placements report up to 20% higher eCPMs vs standard display formats.

Can I use my existing ad tags inside the iFrame Block?

Yes. Paste your existing ad tag directly into the iFrame Block. Your programmatic setup runs inside the Quiz without reconfiguration.

Where should I place the Ad Block inside my content?

Place ads between questions, where user attention is highest, and forward momentum keeps them engaged through the ad. For standard display, avoid the very start before users are invested. For sponsor moments, the end of the Quiz can also work well as a final brand experience.

Do I need coding skills to add an Ad or iFrame Block?

No coding required. Paste your ad tag or iFrame embed code into the block using Riddle's visual builder, and it's live instantly.
