The ideal number of influencers to include in a shortlist for an effective campaign can depend on the size of the campaign, the type of product or service, and the target audience. However, a typical range could be between 10 to 50 influencers.

The reason for shortlisting a number of influencers is to ensure a diverse range of voices and reach. Different influencers attract different audiences, and a mix can ensure broad appeal. Even within a niche, influencers may appeal to unique segments, increasing the likelihood of engagement.

Platforms such as Flinque provide a plethora of tools to aid with influencer discovery, allowing you to identify suitable influencers based on various parameters like audience demographics, engagement rate, content style, and more. This allows brands to shortlist influencers who align most with their branding and target audience.

However, it’s important to investigate each influencer on the shortlist thoroughly. This includes assessing their content quality, audience engagement, alignment to brand values, and authenticity.

It’s also essential to monitor the performance of the influencer campaigns, using analytics from platforms like Flinque. Metrics such as impressions, clicks, conversions, and engagement rates allow marketers to iterate on their influencer selection.

In short, while larger campaigns may require a more substantial shortlist for wider reach, smaller campaigns might benefit from a select group of closely aligned influencers.
