You are interested in associating your offer with authority figures or influencers in your niche market. Such endorsements will provide you with greater social influence that you can leverage to optimize your marketing campaigns.
Collaborating with experts, celebrities or opinion leaders in your industry will offer a valuable endorsement of your product or service, providing testimonials, recommendations, or additional content from the collaborations that will help you to further highlight the benefits and quality of your offer.
Getting a collaboration from a recognized authority figure within the world related to your product will immediately increase your prestige, providing you with the recognition previously gathered by these figures, which will add to your own recognition, increasing your prestige as well.
Social networks and certain streaming or online content platforms can be very well used for this purpose, because they will allow you to share with your audience the endorsement that experts and celebrities are giving you.
When your commercial content is linked to influencers and somehow highlights your association with them, and the reciprocal association of those people with you by giving you their endorsement, the perceived value of your offer will reach a greater dimension, making you even play in another league that will stand out from the league in which your competition is playing. Sometimes these VIP collaborations have to be paid for in some way, but in general it is usually worth it.
