Why do cat videos sell more products for businesses?
A person sees a cat video on social media and shares it with her friend. The friend likes the cat video and receives a prompt to an article on the businesses website, even though this customer isn’t interested in purchasing the service, the fact she is enjoying the cat article increases the websites traffic. Google pushes the website up the rankings, a completely separate costumer to this process searches and finds your business because of this.
A higher ranking webpage in google receives more visitors and therefore more product is purchased.
