Google Adwords (SEM) and Search Engine Optimisation (SEO) are both very reliant on measuring how many visitors you had and from what search terms, where they landed and how long they stayed on your website. Although there is usually a lot more to both of these methods in order to be effective
Facebook and Twitter have their own analytics on your campaigns, showing you the natural vs paid results of your posting and advertising.
At the end of the day each and every customer should be using the right mediums to meet their client demographic where they are at and get their results.
