Influencer Marketing Basics
Influencer marketing connects brands with creators who have engaged audiences. Done right, it drives authentic awareness, trust, and conversions that paid ads can't match.
💡 Why It Works
92% of consumers trust recommendations from individuals over brands. Influencers provide social proof and reach audiences who actively chose to follow them—unlike interruptive ads.
Influencer Tiers
| Tier | Followers | Typical Rate/Post | Best For |
|---|---|---|---|
| Nano | 1K-10K | $10-100 | Hyper-niche, local, high engagement |
| Micro | 10K-100K | $100-500 | Niche expertise, authentic connection |
| Mid-Tier | 100K-500K | $500-5,000 | Balanced reach and engagement |
| Macro | 500K-1M | $5,000-10,000 | Broad awareness, established trust |
| Mega | 1M+ | $10,000+ | Mass awareness, celebrity status |
Pro tip: Micro-influencers (10K-100K) often deliver the best ROI. Their engagement rates are typically 3-5x higher than mega-influencers, and their audiences trust them more as "real people" rather than celebrities.
Instagram Collabs Feature
Instagram Collabs allows two accounts to co-author a single post or Reel. The content appears on both profiles, sharing all engagement, comments, and analytics.
How Collabs Work
Create Your Post
Create a Feed post or Reel as you normally would.
Tag a Collaborator
Tap "Tag people" → "Invite Collaborator" → Search for the account.
Collaborator Accepts
They'll receive a request. Once accepted, the post appears on both profiles.
Shared Everything
Both accounts are credited. Engagement, reach, and comments are shared across both audiences.
📈 Why Use Collabs
- • Double the reach: Content appears in both feeds and Explore
- • Social proof: Both names appear on the post
- • Shared analytics: Both creators see full insights
- • Authentic: Signals real partnership vs sponsored tag
Finding the Right Influencers
The right influencer isn't just about followers—it's about audience alignment, engagement quality, and content fit.
Discovery Methods
Hashtag Research
Search niche hashtags (#veganfitness, #sourdoughbaking). Check top posts and recent posts for active creators.
Competitor Tagged Photos
Check who's tagging and partnering with competitors. These influencers already work with your industry.
Your Own Followers
Review your engaged followers. Some may be micro-influencers already fans of your brand.
Discovery Platforms
Upfluence, AspireIQ, Heepsy, or Instagram Creator Marketplace (for eligible brands).
Vetting Checklist
Red Flags
- • Sudden follower spikes (bought followers)
- • Generic comments: "Nice!" "Great post!" "🔥"
- • High followers, low engagement (under 1%)
- • Inconsistent posting or inactive periods
- • Too many sponsored posts (feeds fatigue)
Outreach Best Practices
Cold outreach gets ignored. Warm, personalized outreach gets responses—and better partnerships.
The 4-Step Warm-Up Method
Follow & Observe (Days 1-3)
Follow them. Watch their Stories. Understand their content style and values.
Engage Meaningfully (Days 4-7)
Leave 3-5 thoughtful comments on their posts. Not "Love this!" but genuine, specific thoughts.
Story Interaction (Days 7-10)
Reply to their Stories with genuine reactions. Build familiarity before you pitch.
Personalized Outreach (Day 10+)
Now reach out. Reference specific content. Show you actually follow them.
📧 Outreach Template
"Hey [Name]! I've been following your content for a few weeks—loved your recent [specific post/Reel about X]. I'm [Your Name] from [Brand]. We [what you do], and I think there could be a really natural fit for us to work together. Would you be open to a quick chat about a potential collaboration? No pressure!"
This approach increases response rates by up to 68% vs generic outreach.
Structuring Partnerships
Clear agreements prevent disputes and ensure both parties know expectations.
Contract Essentials
💰 Payment Models
- • Flat fee: Fixed payment per deliverable (most common)
- • Performance-based: Paid per conversion via promo code/affiliate link
- • Product exchange: Free products in lieu of payment (nano/micro only)
- • Hybrid: Lower flat fee + commission on sales
Co-Creating Content
The best partnerships let creators do what they do best—create authentic content their audience loves.
Content Types That Work
Product Reviews
Honest first impressions, unboxings, or "week with this product" content.
Tutorials/How-Tos
Creator shows how they use your product in their routine or workflow.
Behind-the-Scenes
Visit your facility, meet the team, show product being made.
Giveaways/Challenges
Co-hosted giveaways or branded challenges drive engagement and followers.
🎯 Creative Freedom Wins
Give creators briefs, not scripts. Share your goals, key messages, and must-includes—but let them translate it into their voice and style. Their audience follows them for their authenticity. Over-scripted content feels fake and performs worse.
Measuring ROI
Track the right metrics to prove value and optimize future partnerships.
Key Metrics
| Metric | What It Measures | How to Track |
|---|---|---|
| Engagement Rate | Content resonance | (Likes + Comments + Saves) / Reach |
| Reach & Impressions | Awareness | Request from influencer's analytics |
| Website Traffic | Interest/Intent | UTM links in bio or Stories |
| Conversions | Direct revenue | Unique promo codes per influencer |
| CPA (Cost Per Acquisition) | Efficiency | Total spend / Number of conversions |
| EMV (Earned Media Value) | Content value | Industry benchmarks × engagement |
📊 Always Use Unique Tracking
Give each influencer their own promo code (e.g., JORDAN15) and UTM-tagged links. This lets you attribute conversions to specific creators and determine which partnerships are truly driving business results.
