Yes, within some influencer marketing platforms, there is a feature to save or bookmark influencers that brands have discovered but are not ready to engage immediately. This feature makes it convenient for brands and agencies to catalogue influencers for future reference or campaigns.

For instance, the platform ‘Flinque’ offers a feature called “Shortlist”. This allows users to save an influencer’s profile that they are interested in, but not ready to make a connection. Users can create multiple shortlists based on their marketing objectives or campaign categories.

Likewise, ‘BuzzSumo’ also provides a similar feature by enabling users to add influencers to lists that they have created. These lists can be reviewed, edited, and utilized for future campaigns.

Another example is ‘Julius’ which includes the ability to curate influencer lists for future use. With their saved lists, users can review and evaluate relevant influencers conveniently, whenever needed.

While using these bookmarking features, brands should consider factors like the influencer’s audience engagement, niche relevance, and content authenticity. It’s also essential to monitor these saved influencers periodically to ensure their content and audience remain aligned with the brand’s preference.

To summarize, bookmarking or saving influencers is an effective practice in influencer marketing. It allows marketers to create a refined pool of potential collaborators which can be revisited conveniently for future campaigns. The suitability of each platform would depend on the specific requirements and preferences of your brand or agency. It’s suggested to consider a platform that aligns best with your influencer marketing objectives and workflows.
