| Platform | Best Times (EST) | Frequency | Peak Days |
|---|---|---|---|
9 AM, 12 PM, 7 PM | 3x/day | Mon-Thu | |
| TikTok | 6 AM, 10 AM, 7 PM | 2-3x/day | Thu-Sun |
| Twitter/X | 8 AM, 12 PM, 5 PM | 3-5x/day | Tue-Thu |
| YouTube Shorts | 2 PM, 8 PM | 1-2x/day | Fri-Sun |
2 PM, 8 PM, 11 PM | 5-10x/day | Weekends |
Configure your N8N workflow to automatically adjust posting times based on your audience's primary location. If 60% of your followers are in EST, 30% PST, and 10% UK, schedule posts to hit all three time zones for maximum reach.
Pro move: Post the same content 3 times (EST morning, PST morning, UK evening) to different platforms to maximize exposure without appearing spammy.
Tool: Airtable or Google Sheets
Structure: Create database with columns:
Trigger Node: Schedule
Cron expression: Run every hour to check for scheduled posts
0 * * * *Node 2: Airtable Query
Filter: Status = "Pending" AND Scheduled Time ≤ Current Time
Node 3: HTTP Request (Download Image)
Fetch image from Dropbox/Drive URL, convert to buffer
Node 4: Instagram API Post
Use official Instagram Graph API or unofficial library
Node 5: Update Airtable
Set Status = "Posted", save Post ID for analytics
Add error nodes to catch failed posts:
{
"nodes": [
{
"id": "1",
"type": "n8n-nodes-base.cron",
"name": "Schedule Trigger",
"parameters": {
"cronExpression": "0 * * * *"

},

}TikTok requires business account approval. Alternative: Use Selenium automation with n8n-nodes-base.executeCommand
Vertical 9:16 ratio, 15-60 seconds. Use FFmpeg in N8N to convert images to video with music overlay.
Pull trending sounds via TikTok API, auto-match to content library based on vibe/genre.
Twitter API v2 requires paid plan ($100/month). Use n8n Twitter node for direct posting.
1:1 or 16:9 ratio. Thread creator node for storytelling posts (split long captions into threads).
Auto-reply to comments using GPT-4 node. Filter for non-spam comments, generate personalized responses.
N8N workflow runs daily to scrape trending content:
GPT-4 node analyzes trends and filters by relevance:
Prompt:
"Analyze these trending topics: [LIST]. My AI influencer is a fashion/lifestyle character. Which 3 trends are most relevant? For each, suggest a content idea that fits my character."
Two approaches:
Real-time Generation
Trigger ComfyUI via API to generate trend-specific image immediately (30-60 sec)
Library Matching
Use AI to match existing content library images to trend (instant posting)
Instead of generating trend content daily, batch-create 20-30 "trend-ready" images monthly:
When N8N detects relevant trend, it auto-selects matching image from library and posts within minutes.

"I spend 2 hours per week managing my AI influencer. The automation handles everything - posting, optimal timing, even trend integration. I focus on strategy and brand outreach. This system freed me to launch 2 more AI influencers using the same workflow."
Create 5-10 caption templates that match your influencer's voice:
Template 1: Lifestyle Share
"Living my best life in [LOCATION/OUTFIT]. What are you up to today? 💫 [QUESTION]"
Template 2: Product Showcase
"Obsessed with this [PRODUCT] from [BRAND]. The quality is unreal! 🔥 [CALL_TO_ACTION]"
Template 3: Inspirational
"[MOTIVATIONAL_QUOTE]. Remember: [PERSONAL_INSIGHT]. Who else needed this today? 💪"
System Prompt:
"You are Eva, a 24-year-old AI fashion influencer. You're bubbly, positive, and love engaging with your community. Write captions that feel authentic, use 1-2 emojis max, and always end with a question to drive engagement. Keep captions under 150 characters."
User Prompt:
"Write a caption for this image: [IMAGE_DESCRIPTION]. Use Template [TEMPLATE_NUM]. Include hashtags: #fashion #style #ootd"
Store hashtag sets in Airtable (10-15 hashtags per set). Rotate sets to avoid Instagram shadowban. N8N randomly selects one set per post for variety.
Using the official Instagram Graph API is completely allowed and encouraged by Meta. Third-party automation tools that scrape or simulate user behavior may violate TOS. Stick with official APIs or approved partners (Buffer, Later, Hootsuite) to stay compliant.
N8N offers a free self-hosted version (unlimited workflows). Cloud version starts at $20/month for 2,500 executions. For AI influencer automation, you'll need ~500-1000 executions/month, making the free self-hosted version perfect. Host on a $5/month DigitalOcean droplet.
Yes! Load your entire monthly calendar into Airtable, and N8N will automatically post at scheduled times. You can schedule up to 3 months in advance if you batch-create enough content. This "set it and forget it" approach is the ultimate time saver.
Build error handling into your N8N workflow: retry 3 times with delays, send you a Telegram/Discord alert if all retries fail, and mark the post as "Failed" in Airtable. You can manually review and repost failed content. Failure rate is typically under 1% with proper setup.
For comments: Use N8N to monitor new comments (Instagram API webhook), filter out spam, and generate responses with GPT-4. Review GPT responses before posting (human-in-loop). For DMs: Use Manychat or MobileMonkey for automated replies to common questions, routing complex queries to you.
TikTok's official API requires business account approval. Alternative: Use browser automation (Puppeteer via N8N) to simulate manual posting. More fragile and against TOS, but works. Recommended: Apply for business account (free, takes 1-2 weeks) for official API access.
One 4-hour session monthly is ideal for most creators. If posting to multiple platforms (Instagram + TikTok + Twitter), bump to 6 hours monthly or two 3-hour sessions. Key is consistency - same day each month, calendar blocked, distraction-free.
Set up monitoring: N8N sends you daily recap emails (X posts published, Y failed, Z pending). Weekly analytics report (follower growth, engagement rates, top posts). Monthly deep dive (compare to manual posting benchmarks, identify improvement areas).
