There is a lot of factors that affect SEO ranking. Google ratings and customer reviews are two of the most influencial factors. A good overall rating and positive reviews together indicate trustworthiness of a business and overall customer satisfaction. Note that reviews would be even more effective if the reviewer included the keywords that your site is ranked for on Google and Google My Business.
Hi Christian, it is critical to track how many visitors or social shares you achieved through your campaigns. This would lead to measuring how many new customers were delivered, how much revenue did they generate and what is the return on the marketing investment. The top three matrices that digital marketers should measure are reach (how many potential audience your campaigns are reaching), engagement (how much time they are speding in consuming and sharing the content) and conversation (if they are turning into quantifiable sales leads). Hope this makes sense.
