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.
The majority of web traffic is driven by the major commercial search engines, Google, Bing, and Yahoo!. Although social media and other types of traffic can generate visits to your website, search engines are the primary method of navigation for most Internet users. This is true whether your site provides content, services, products, information, or just about anything else.
There are numerous repositories to source affiliate products and services from. However, some of the biggest are sites like Clickbank, Commission Junction, LinkShare and JVZoo. You'll need to go through an application process, for the most part, to get approved to sell certain products, services or digital information products. Once approved, be prepared to hustle.
