Why this risk is underestimated
When a brand and its competitor use the same influencer simultaneously, both messages cancel each other out. The audience no longer knows how to tell them apart. The brand that paid half the price benefits from the same positioning. The influencer, for their part, did nothing wrong — they simply accepted two different briefs.
The problem is structural: without systematic history checks, brands run this risk with every campaign. And contrary to what one might think, this is not exclusively a big-budget issue. An e-commerce brand with a €15,000 annual budget can lose most of its impact on a single poorly secured campaign.
The good news: it is one of the easiest risks to eliminate, provided you have the right tools and the right reflexes.
4 reasons why manual verification fails
- Sponsored posts disappear or are archived without notice — a sponsored story no longer exists after 24 hours, and many influencers archive their commercial posts after a few months.
- #ad, #partnership mentions are inconsistent across creators — some tag systematically, others only on certain platforms, others never (sometimes in violation of ASA/ARPP rules).
- Going back 12 months of history across 3 platforms = 4–6 hours per influencer — time that no one actually spends before sending a brief, especially when evaluating 20 profiles simultaneously.
- Collaborations without visible posts (stories, newsletters, events, gifting) leave no public trace — and these are often the ones that build the most durable relationship with the audience.
"An influencer who has worked with 3 brands in your niche in the last 6 months is a strong signal — but detecting it manually takes an average of 4 hours per profile."
Checklist: verifying a profile manually
If you only have one or two profiles to check and time to spare, here is the most complete manual method:
- Browse the last 100 Instagram posts looking for #partnership or #ad
- Repeat on TikTok (account settings > "Sponsored posts" if available)
- Check YouTube for videos with "in partnership with" in the description
- Review the Linktree or bio link: often reveals active partnerships
- Google:
"[influencer name]" site:instagram.com "partnership"or"[name] x [brand]"
This method covers approximately 60 % of recent partnerships. It misses stories (ephemeral), collaborations without a dedicated post, and anything older than 6 months.

Frequently asked questions
Can an influencer work with two competing brands?
Yes, legally, unless an exclusivity contract has been signed. But for a brand, collaborating with an influencer who also works for a direct competitor dilutes the message and reduces perceived impact. This is why checking partnership history before any contact has become a non-negotiable step.
How to check an influencer's partnership history for free?
Manually: browse the influencer's Instagram/TikTok archives, look for #partnership or #ad mentions, and use Google with the query "[name] site:instagram.com partnership". This method takes 3–5 hours per profile. With Sulico Conflict Checker, 1 free check per day with no account required.
What is an exclusivity clause in an influencer contract?
It is a clause that prohibits the influencer from working with competing brands during a defined period (generally 30 to 90 days). It can be sector-specific (e.g. beauty) or total. It must be negotiated before signing and include specific compensation.
How much does an influencer conflict mistake cost a brand?
At minimum, the cost of the lost campaign if you did not detect it beforehand. If discovered after signing, add the costs of contractual renegotiation, loss of pricing exclusivity, and dilution of your message if the influencer posts for a competitor in the same weeks.
