A practical guide to influencer marketing for growing businesses

Executive overview

Influencer marketing works by borrowing trust from someone who already has influence over your target audience. It scales from nano-influencers with 1,000 followers to celebrities with millions — and budget is not the barrier most assume.

The process has five steps: define your objective, find candidates, vet them rigorously, reach out, and collaborate.

Follower count is a vanity metric — engagement rate, engagement quality, and growth trend are what determine whether a campaign delivers.

Campaign objectives

• Brand awareness: introduce your product via a personal story and loose recommendation
• Interest and desire: teach the audience about a problem and how your product solves it
• Entice purchase: offer exclusive discounts or sign-up deals through a unique link

Finding influencers

• Start a spreadsheet: name, channel link, follower count, platform
• Google "top [niche] influencers" and scan list posts for candidates
• Search platforms directly (e.g. YouTube keyword search for tutorial content)
• Reverse-engineer competitors: on Instagram, follow sponsored hashtags; on YouTube, use Ahrefs Site Explorer to find internal redirect links pointing to a competitor's sponsor URL

Vetting: brand fit

• Assess the influencer's persona and core values — do they align with your brand?
• Mismatch examples: a "get rich quick" creator promoting resume services; a luxury-focused creator promoting budget jewellery
• Strong brand fit matters for the long term, not just a single post

Vetting: engagement metrics

• Engagement rate: use SocialBlade (Instagram, YouTube, TikTok, etc.); decent range is 2–7% for Instagram
• For YouTube, use vidIQ — above 5% on videos older than 2 months with significant views is strong; below 2% is weak
• Engagement quality: read comments manually — generic emoji responses signal low quality regardless of count
• Growth trend: use SocialBlade's long-term view; prioritise channels in an upward trend; a flatlining channel will deliver subpar results even with clean engagement metrics

Reaching out and collaborating

• Find contact details on About pages or social profiles
• Pitch: introduce yourself, explain the fit, ask if they're open to a sponsored post
• Influencers will vet you too — they protect their personal brand
• Pricing ranges from free product to long-term contracts; start by asking if there's interest
• Collaborate on format: giveaways, referral programmes, exclusive deals, co-created content, event invites
• The only legal requirement: disclose that the sponsorship is paid
