Sonstiges » corporate explainer error??

Hello,
I read some magazines,books.I want to stand in this field.I am new in this field and i want to know about this field.According to a recent survey conducted by Video Rascal, 85 percent of people are more likely to buy a product once they see an accompanying explainer video. Explainer videos help budding business owners keep tally of how many visitors on their sites could become actual customers. Although most businesses manually count sales to see what products are most popular, explainer videos keep track of what product or service potential customers are interested by displaying the number of views on each video. Is this correct? I went through many resources and also checked Corporate Explainer Examples but did not find the right solution. Please help me out.

Any help will be appreciated.
Thank you.
