When promoting affiliate offers, just make sure you are fully aware of all the terms and conditions attached to your affiliate program. Some programs can be strict about how they allow you to promote their products. For example, some may limit you to banner ads and links only, while others will allow you to use paid advertising, but won't allow email marketing.
When running PPC ads, it's important that you keep careful track of the specific ads and keywords that you're targeting. You can do this by using the Google Analytics UTM builder to create campaign URLs that you can use to track the campaign source, the medium and any keywords or terms that you might be targeting. This way, you can determine the effectiveness of any campaign that you run and figure out the precise conversion rate.
Today, there are tons of examples of successful, high-profile YouTube marketing campaigns. From Moz and Rand Fishkin’s informative Whiteboard Fridays to Chipotle’s acclaimed series of emotionally powerful animated shorts, there are plenty of brands currently demonstrating just how much potential there is to create value and awareness by promoting great video content on YouTube.
