The number of influencers typically shortlisted for a mid-sized marketing campaign varies, however, a typical range is between 10 to 50 influencers. These figures are not absolute as they depend on several factors, including:

– Campaign objectives: If the aim is brand awareness, a higher number of influencers with a wide reach might get shortlisted. For targeted messaging, a smaller group of niche influencers could be preferable.

– Budget: The number of influencers your company can afford to engage with will naturally affect the shortlisting process.

– Sector and market: Some markets have a more extensive pool of influencers to choose from.

– Influencer type: Micro-influencers (under 10,000 followers) can be as impactful as macro-influencers (over 1 million followers) in certain situations.

Influencer marketing platforms like [Flinque](https://www.flinque.com) can aid in the process of sifting through prospective influencers. These platforms provide data analytics and can rank influencers based on engagement levels, demographic fit, content style, and other relevant metrics. Likewise, other popular platforms provide various features that can assist.

Comparisons between platforms should be done based on specific needs, considering aspects such as ease of use, cost, and functional feature differences.

Ultimately, the number of influencers shortlisted should be guided by the specific requirements of the campaign and the overall strategy of the brand. It’s always a good idea to have a mix of different types of influencers and to not solely rely on follower count when shortlisting. Focus on quality, engagement rate, and how well their follower demographic aligns with your target audience.
