"As an owner of a small search engine marketing company, having access to the latest info on SEO is critical. I have had consultation phone calls with many of the top SEO'S and have sent my employees to training at one of the very top search marketing companies. Talking to Jim has been the best experience yet. He doesn't beat around the bush and tells you the real deal on getting organic ranks. We were stumped in particular on link building despite doing it for many years. Even after researching through forums and asking questions at the search strategies conference, we still did not have the whole picture and a practical set of white hat techniques to employ. Jim solved that among other technical issues our programmer had. I am truly looking forward to our next chat." John M.

Shifting the focus to the time span, we may need to measure some "Interim Metrics", which give us some insight during the journey itself, as well as we need to measure some "Final Metrics" at the end of the journey to inform use if the overall initiative was successful or not.

Many laws specifically regulate the ways online ads are delivered. For example, online advertising delivered via email is more regulated than the same ad content delivered via banner ads. Among other restrictions, the U.S. CAN-SPAM Act of 2003 requires that any commercial email provide an opt-out mechanism.[108] Similarly, mobile advertising is governed by the Telephone Consumer Protection Act of 1991 (TCPA), which (among other restrictions) requires user opt-in before sending advertising via text messaging.
In contrast, the European Union's "Privacy and Electronic Communications Directive" restricts websites' ability to use consumer data much more comprehensively. The EU limitations restrict targeting by online advertisers; researchers have estimated online advertising effectiveness decreases on average by around 65% in Europe relative to the rest of the world.[60]:58
Let’s say that you’re running a company that specializes in shoes. Your customer base knows that you’re a shoe expert but also values your input on other high quality products — like handbags. Maybe your customers have asked you about handbags, and you find yourself recommending the same options over and over again. As a shoe vendor, you’re acting as a marketer for the handbag company.
According to a paper by Duncan Watts and colleagues entitled: "Everyone's an influencer",[66] the most common risk in viral marketing is that of the influencer not passing on the message, which can lead to the failure of the viral marketing campaign. A second risk is that the influencer modifies the content of the message. A third risk is that influencers pass on the wrong message. This can result from a misunderstanding or as a deliberate move.
