Best Practices for Stock Avatars

1. Choose Avatars That Match Your Audience

Select avatars that look like your target customers—not models, but real people your audience can relate to.

Consider:

  • Demographics (age, gender, ethnicity)

  • Style (professional, casual, creative)

  • Setting (office, home, outdoor)

  • Personality (friendly, authoritative, energetic)

2. Test Multiple Avatars

With unlimited generation, test different avatars to see which resonates most with your audience.

Testing framework:

  • Create same video with 3-5 different avatars

  • Run as ads or share on social media

  • Track engagement, CTR, and conversions

  • Scale the winners

3. Match Avatar to Content Type

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

4. Maintain Consistency Within Campaigns

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.

5. Leverage Diversity

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

Best Practices for Custom Avatars

1. Invest in Quality Source Video

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

2. Choose the Right Person

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

  • Long-term commitment to the role

  • Voice quality and clarity

3. Use for High-Impact Content

Maximize ROI by using custom avatars where personal connection matters most.

High-impact use cases:

  • Personalized sales outreach

  • Executive communications

  • High-value customer interactions

  • Thought leadership content

  • Trust-critical communications

4. Scale Personalization

Once you have a custom avatar, leverage it for mass personalization.

Personalization strategies:

  • Address recipients by name

  • Reference specific details (company, role, pain points)

  • Customize CTAs for each recipient

  • Localize for different markets and languages

5. Maintain Brand Consistency

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

  • Sales presentations and proposals

  • Customer communications

Common Mistakes to Avoid

Mistake 1: Using Stock When Custom Would Build More Trust

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.

Mistake 2: Creating Custom Avatars for Everyone

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.

Mistake 3: Poor Quality Source Video for Custom Avatars

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.

Mistake 4: Not Testing Stock Avatars

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.

Mistake 5: Inconsistent Avatar Use

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.
