After researching the topic I got an impression that featuring a product on a stream or instagram is more powerful than ads on youttube and instagram. Is it true? In tha case it looks like that more and more companies should start allocation most of the marketing money towards accessing the customers via the social media channel and the influencers. Would be happy to read some good article and analytics on this topic.
It’s actually better for the brand to be more established on multiple platforms because as the targeted person switches apps, they will see your image again. This really increases the chances of you getting clicks and converting. The money aspect of your question is easy, start off by doing the same amount on each platform then adjust as you receive more data. Great question.
