Influencer Marketing
Also known as: creator marketing, influencer partnerships
Definition
Influencer marketing is paying or partnering with creators who have built an engaged audience to promote a brand's products or services to that audience.
Influencer marketing turns the trust a creator has built with their audience into a distribution channel for a brand. Unlike traditional ads, influencer content carries the implicit endorsement of someone the audience already knows — which is why it consistently outperforms branded content on engagement, click-through, and conversion.
The 2026 market splits into four creator tiers by audience size. Mega (1M+ followers) for mass awareness. Macro (100K-1M) for category-leading reach. Mid-tier (10K-100K) for the best balance of reach and engagement. Micro (1K-10K) for the highest engagement rates and lowest cost per result. Most ecommerce brands now allocate the majority of influencer budget to micro and mid-tier creators because the math works better.
The biggest 2026 shifts are creator-led whitelisting (running paid ads from a creator's handle), gifting-at-scale programs (sending products to 50-200 creators per month), and AI-assisted creator discovery and brief management. Disclosure (#ad, #sponsored, paid partnership tags) is mandatory in the US, UK, and EU and is enforced by the FTC and ASA.

Frequently asked questions
What size influencer should I work with?
For most ecommerce brands, micro (1K-10K) and mid-tier (10K-100K) creators deliver the best ROI. Mega-influencers are useful for launches and brand awareness but are usually overpriced for direct response.
How much should I pay an influencer?
A common rule of thumb is $100 per 10K followers for a single Reel, plus usage rights add-ons. Niche, engagement rate, exclusivity, and deliverables shift this significantly.
Do I need to disclose paid partnerships?
Yes. The FTC (US), ASA (UK), and most EU regulators require clear disclosure (#ad, #sponsored, or the platform's native paid partnership tag) on any sponsored content. Non-disclosure can result in fines.
