Offsite Embeds for Mobile Devices: Best Practices and Specs

Overview

This guide is for brands, growth teams, and ad operations teams using Genuin’s Offsite Ad Creative to distribute video content across mobile environments.

Use mobile offsite embeds when you want to extend reach beyond owned properties, activate high-performing video content in paid or partner placements, and maintain consistent engagement, measurement, and brand safety across mobile surfaces.

Mobile environments impose strict constraints on size, performance, and interaction. Following Genuin’s mobile embed best practices ensures:

Faster load times and smoother playback
Higher viewability and engagement rates
Accurate tracking and attribution
Brand-safe, compliant delivery across ad networks

What Are Offsite Mobile Embeds?

Offsite mobile embeds are video ad creatives generated in Brand Control Center and distributed outside your owned web or app experiences. These embeds render as responsive, self-contained video units optimized for mobile screens and touch-based interaction.

They support:

Autoplay and user-initiated playback
Engagement actions (Repost, Spark, Comment, Share)
Profile or destination redirection
Integrated reporting and analytics

Supported Mobile Embed Sizes

Genuin supports industry-standard mobile creative dimensions to ensure compatibility across ad exchanges, networks, and publisher placements.

Recommended Sizes

300 × 250 (Mobile Medium Rectangle)
300 × 600 (Half Page – limited mobile use)

Aspect Ratio

Default: 9:16 (vertical video)
Adaptive scaling supported for responsive containers

Use full-viewport vertical sizes whenever possible for maximum engagement.

Mobile-Specific Best Practices

1. Autoplay Behavior

Enable autoplay video with muted audio by default
Ensure compliance with platform and browser autoplay policies
Allow tap-to-unmute for user control

2. Performance Optimization

Keep creative payloads lightweight
Avoid excessive overlays or heavy UI elements
Use adaptive video display to fit varying screen sizes

This ensures smooth playback even on low-bandwidth connections.

3. Button Timing & Visibility

Use Button Delay (Immediately or 3/4/5 seconds) to avoid immediate visual clutter
Display CTAs after initial playback engagement
Keep CTA text concise and thumb-friendly

4. Engagement Controls

Enable engagement tools selectively based on campaign goals:

Repost
Spark
Comment
Share

Avoid enabling all actions by default in performance-focused campaigns.

Tracking & Measurement Requirements

Google Tag Manager (GTM)

For accurate attribution and performance tracking:

Configure a valid Google Tag Manager ID
Ensure GTM is loaded before creative render

Key Metrics Tracked

Views and completion rates
Engagement actions
Click-throughs and redirects
Autoplay vs user-initiated plays

All metrics roll up into BCC reporting dashboards.

Redirection & Navigation

Redirect to Profile

Enable when discovery and brand affinity are goals
Allows users to tap through to brand, community, or creator profiles

External Linkouts

Ensure destination pages are mobile-optimized
Avoid deep links that break in in-app browsers

Media Play Guidelines

Autoplay

Supported across most mobile placements
Defaults to muted playback

Looping

Use sparingly to avoid user fatigue
Recommended for short-form clips under 15 seconds

Governance, Safety, and Control

Offsite mobile embeds inherit Genuin’s core safeguards:

AI-powered moderation and brand safety filters
Centralized activation and deactivation controls
Ability to pause or disable creatives instantly

This ensures offsite distribution remains governed, auditable, and reversible.

Summary

Offsite embeds for mobile devices allow brands to scale video distribution beyond owned channels while preserving performance, measurement, and control. By following Genuin’s recommended sizes, playback behaviors, and tracking standards, you can deliver high-impact mobile video experiences that are fast, compliant, and measurable.

Mobile-first execution isn’t optional, it’s foundational to effective offsite activation.
