Inbound Marketing vs. Interrupt Marketing
Inbound marketing happens when someone is searching for something and it appears in front of them. They are already looking for your service so the likelihood of them following through to view what you have is greater than with interrupt marketing. That is our job. To make sure that if someone is searching for something that we put your website in front of them.
Interrupt Marketing happens when someone is doing something but is interrupted by an advertisement. An example of this is television and radio ads. People were not asking for it so they leave to make a sandwich. Repetition to embed it in your mind is needed to get the advertisers point across.
