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. As an example, most of social media metrics and indicators such as likes, shares and engagement comments may be classified as interim metrics while the final increase/decrease in sales volume is clearly from the final category.
There’s obviously a huge number of reasons why a website might link to another and not all of them fit into the categories above. A good rule of thumb on whether a link is valuable is to consider the quality of referral traffic (visitors that might click on the link to visit your website). If the site won’t send any visitors, or the audience is completely unrelated and irrelevant, then it might not really be a link that’s worth pursuing.
It's clear that online marketing is no simple task. And the reason why we've landed in this world of "expert" internet marketers who are constantly cheerleading their offers to help us reach visibility and penetrate the masses is because of the layer of obscurity that's been afforded to us in part thanks to one key player: Google. Google's shrouded algorithms that cloud over 200+ ranking factors in a simple and easy-to-use interface has confounded businesses for well over a decade now.
