Demographics (age, gender, ethnicity)
Style (professional, casual, creative)
Setting (office, home, outdoor)
Personality (friendly, authoritative, energetic)
With unlimited generation, test different avatars to see which resonates most with your audience.
Testing framework:

Run as ads or share on social media
Track engagement, CTR, and conversions
Scale the winners
Different content types benefit from different avatar styles.
Professional/corporate content: Polished, office-setting avatars
Casual/lifestyle content: Relaxed, home-setting avatars
Educational content: Approachable, friendly avatars
Support content: Helpful, patient avatars
While variety is good, maintain consistency within specific campaigns or content series.
Example: Use the same avatar for all videos in a product tutorial series, then switch to a different avatar for a new campaign.
Use stock avatars to represent diverse perspectives and reach different audience segments authentically.
Strategic diversity:
Different avatars for different customer personas
Multilingual content with culturally appropriate avatars
Inclusive representation across all content
Your custom avatar is only as good as the video you provide.
Recording tips:
Use good lighting (natural light or ring light)
Clear, crisp audio (use external mic if possible)
Stable camera (tripod or stable surface)
Clean background (minimal distractions)
Clear mouth movement (enunciate clearly)
Natural expressions (smile, blink naturally)
Professional appearance (dress for your brand)
40-60 seconds of natural speaking
Not everyone should have a custom avatar. Choose strategically.
Good candidates:
Company founders and CEOs
Sales leaders and top performers
Subject matter experts
Brand ambassadors
Coaches and consultants
Professional service providers
Consider:
On-camera comfort and presence
Brand alignment and credibility

Localize for different markets and languages
Use your custom avatar consistently across channels to build recognition and trust.
Consistency touchpoints:
Email signatures with avatar video
Social media profile and content
Website homepage and about page

The problem: Using generic stock avatars for trust-critical communications (sales, healthcare, financial advice) where personal connection matters.
The solution: Invest in custom avatars for relationship-based content; use stock for general information.
The problem: Creating custom avatars for team members who don't need them, wasting time and resources.
The solution: Create custom avatars only for key spokespeople; use stock for everything else.
The problem: Recording custom avatar source video with bad lighting, audio, or framing—resulting in poor avatar quality.
The solution: Follow best practices for recording; invest a few minutes minutes in proper setup for years of quality content.
The problem: Choosing one stock avatar and using it for everything without testing alternatives.
The solution: Test multiple avatars to find what resonates; different audiences prefer different styles.
The problem: Switching avatars randomly within campaigns or content series, confusing audiences.
The solution: Maintain consistency within campaigns; switch strategically between campaigns or content types.
