Platform strategy and profile optimization
Publishing Across Platforms
Aria has a brand, a voice, and her first video. But where should she show up?
In this lesson, you'll learn how to choose the right platforms, optimize Aria's profiles for discoverability and first impressions, and develop platform-specific strategies.
Welcome to Unit 2 — this is where Aria starts growing!

In your opinion, what should drive your decision about which platforms to publish on?
Understanding the Major Platforms
Not every video works the same on every platform. Each one has its own format preferences, length sweet spots, and engagement signals. Let's look at the three primary platforms for short-form video: Instagram Reels, TikTok, and Instagram Stories.
Instagram Stories
- Length: Up to 60 seconds (longer videos split into multiple clips).
- Format: 9:16 vertical. Disappear after 24 hours (unless saved as Highlights).
- Engagement signals: The strongest measurable engagement actions are Replies, Sticker interactions (polls, questions, sliders), and Taps Back (rewatch).
- Best for: Bond-focused content that deepens relationships with existing followers.
Instagram Reels
- Length: Up to 3 minutes is a safe ceiling if you want recommendations to new audiences; Reels over 3 minutes may not be recommended to non-followers.
- Format: 9:16 vertical.
- Engagement signals: Watch behavior and Saves and shares are the strongest engagement signals. Hook within 3 seconds. Keyword-rich captions help since Reels now appear in Google search results.
- Best for: Value-driven content your audience wants to come back to — tutorials, tips, how-tos.
TikTok Videos
- Length: Up to 60 minutes (TikTok supports long videos, but short videos often win when retention stays high).
- Format: 9:16 vertical.
- Engagement signals: Completion rate is the key signal — viewers watching to the end matters most. Trending sound can improve discoverability because sounds are part of the video information TikTok uses to recommend content.
- Best for: Discovery — reaching new audiences who don't follow you yet.

Post Everywhere, Grow on One
Now that you know what each platform rewards, a natural question: does Aria need to be on all three? Yes — but not equally.
Pick one platform as your primary — the one where your target audience is most active. That's where you reply to every comment, engage with other creators, and study what performs.
Your other platforms still get content, but they run on lighter effort. The key to making this work without tripling your workload? Repurposing.
Your Profile Is Your Landing Page
Before anyone watches Aria's first video, they see her profile. It takes seconds for someone to decide whether to follow.
Think of every profile as a landing page. Each element needs to answer one question: "Why should I follow this account?"
A strong AI avatar profile needs four things:
- Profile photo: A clear, high-quality Midjourney image of Aria — the same one used in your videos.
- Display name: Include a keyword your audience actually searches for (e.g., "Aria | Calm Morning Routines").
- Bio: A concise value statement — who this is for and what they'll get. No filler.
- Link: Your highest-value destination — a landing page, lead magnet, or link-in-bio tool.
This is where discoverability starts. Display names and bios are searchable on both Instagram and TikTok. The right keywords mean Aria can be found by people who've never seen a single video.

Why does Aria's display name include "Calm Morning Routines" instead of just "Aria"?
Adapt the Bio, Keep the Brand
Aria should feel like the same person on every platform. Same profile photo, same core message, same voice. But bios don't need to be identical — they should fit each platform's culture.
TikTok bios are shorter and more casual. Instagram bios can use line breaks and structured formatting. While the brand stays the same, the packaging shifts slightly.

One More Thing for AI Avatars
When you're publishing an AI avatar across multiple platforms, keep one extra thing consistent: your disclosure.
Add a clear statement to Aria's bio on every platform — something like "AI avatar · real routines · created by [you]." This keeps you compliant with Instagram, TikTok, and EU labeling requirements from day one, and it builds the transparency that makes organic growth stick.
Great Work!
Same Aria, same message, different packaging. The Instagram bio is structured and searchable. The TikTok bio is punchy and casual. Both sound like her — and both tell a new visitor exactly what they'll get. Now that Aria's profiles are set up and optimized, let's fill them with content.
Repurposing Across Platforms
You don't need to create entirely new content for every platform. Smart creators repurpose — adapting one core piece of content into multiple formats.
Your 45-second Reel can become a 30-second TikTok with a faster hook and trending sound, plus a 15-second Story teaser with a poll.

Excellent!
One script, three platforms, three different outputs — each optimized for how audiences behave on each platform. This is how you scale content without starting from scratch every time.
Writing Platform-Native Captions
The video gets attention; the caption keeps it — and tells the algorithm what your content is about.
Each platform treats captions differently:
- On Reels, captions are searchable. Treat them like mini-SEO — include keywords your audience would search for.
- On TikTok, captions are short and punchy — often just the hook restated or a question.
- On Stories, captions are optional since the sticker does the work.

Choose one
Creator A posts 5 videos in one week, then nothing for three weeks. Creator B posts 2 videos per week, every week, for a month. Which approach builds a stronger brand over time?
Batch Production in HeyGen
Consistency gets easier when you batch your production. Instead of scripting, filming, and publishing one video at a time, batch the workflow.
Script 4-6 videos in one Claude session using your content calendar. Then open HeyGen and produce them all in sequence: same avatar, same voice, same brand settings.
This way, you're spending one focused hour producing a week or two of content instead of context-switching every day.

Choose based on audience → Optimize your profile → Adapt your content → Stay consistent.
Your platform strategy starts with where your people are. Your profile converts visitors into followers. Your content adapts to each platform's culture while the brand voice stays the same. And consistency is what compounds into real growth.
Aria Has a Home!
You've made three important steps in this lesson:
- You now know which platforms match your audience.
- You optimized Aria's profiles to convert visitors into followers on every platform.
- You have a repurposing strategy that turns one video into three platform-native pieces of content.
In the next lesson, you'll learn how to collaborate — finding peers and brands that align with Aria's values, approaching them professionally, and creating partnerships that grow your audience and credibility.
The profiles are live, and the workflow is set. Let's connect Aria with the right people!
