Influencer Budget Allocation: Deciding How Much to Spend and on Whom

There is no universal answer, but a practical starting framework for SMEs:

If you're new to influencer marketing: start with a test budget equivalent to 1–2 months of your paid social spend. The goal is to build benchmark data — what ROAS, CAC, and customer quality does influencer marketing generate compared to your existing channels?

If you have influencer history: allocate based on your proven ROAS. If influencer marketing generates £3 of revenue for every £1 spent and your paid social generates £2, it may make sense to shift budget toward influencer until the ROAS equalises.

As a % of revenue: consumer product brands typically spend 5–15% of revenue on all marketing; influencer as a share of that varies widely — some DTC brands allocate 50% of marketing budget to creators, others 10%.

Most brands allocate influencer budget across multiple tiers:

Mega (1M+ followers): massive reach, high cost (£5,000–50,000+ per post), low engagement rates, difficult to attribute ROI. Justified for brand awareness plays, not performance marketing. Use rarely.

Macro (100k–1M): high reach, high cost (£1,000–10,000), moderate engagement. ROI is possible but harder to prove. Use for hero campaigns.

Mid-tier (10k–100k): sweet spot for most SME brands. Affordable (£200–2,000), engaged audiences, often category-specific. Best ROAS in most studies. Use as the backbone of your programme.

Micro (1k–10k): very low cost (gifting-only or £50–200), high engagement, hyper-niche. Good for community-building and authentic content. Use at volume.

Nano (< 1k): essentially UGC with a small audience. Gifting only. Use for product seeding rather than reach.

Once you have creator performance data in AskBiz, allocate budget based on ROI tiers:

• Top 20% by ROI: increase fee budget — these creators are proven. Negotiate ambassador deals or series retainers.
• Middle 60% by ROI: maintain current spend. Test different content formats or brief approaches to improve ROI.
• Bottom 20% by ROI: do not re-book unless there's a specific non-revenue reason (brand fit, reach to new demographic). Reallocate their budget to top performers.

Ask AskBiz: *'Show me my creator partnerships ranked by ROI for the last 12 months and flag which creators I should prioritise re-booking.'*

Gifting (no fee, product only):

• Appropriate for: micro and nano creators, initial seeding campaigns, building UGC volume
• Cost is product COGS, not retail value — track this
• No obligation for creators to post (though most will for good brands)
• Less control over timing and messaging

Paid partnerships:

• Appropriate for: mid-tier and above, specific campaign goals with required posting dates
• Higher cost but guaranteed deliverables
• Full brief compliance expected
• Requires disclosure (#ad, #sponsored) per UK ASA guidelines

For most SME brands, a programme combining gifting (high volume, lower control) with paid partnerships (lower volume, higher control) delivers the best blend of scale and performance.
