Hashtag misuse is a small thing that quietly costs reach. Stuffing dozens of irrelevant tags looks spammy and can suppress a post, while a few relevant ones help discovery. The one hashtag you cannot skip is a clear disclosure tag, since undisclosed paid posts break platform rules and trust.
Whether poor hashtag use can hurt an influencer campaign rather than help it.
Hashtags are minor until they are misused, at which point they quietly cost you. Overloading a post with dozens of loosely related tags looks spammy and some platforms suppress it, while a handful of genuinely relevant tags actually aids discovery. The non-negotiable one is disclosure: a clear paid-partnership or ad tag is required by platform rules and by regulators in many regions, with skipping it risking both a takedown and a trust hit. Let the creator handle the discovery tags, since they know what works for their audience, while making disclosure a firm requirement in the brief.
