SEO and SEM remain the top methods for succeeding at digital marketing. In order to determine, the better tool, business analysis was conducted using data. First one has to analyze the goal. SEM is the clear winner when we look at leads, paid traffic, targeting or inbound phone calls. The jury is divided when it comes to aspects such as emails, contact forms, branding and walk-ins. SEO gets the higher rating when we analyze website, organic or referral traffic. In case of tight budgets, SEM is the desirable option. In terms of time frames, SEO will win marathons while SEM is the sprinter. Location is less important when it comes to either of the two strategies.
