A recent study “State of Digital Marketing Report” indicated that for both B2B (57%) and B2C (41%) websites, search engine optimization was the most effective marketing tactic for lead generation over paid search advertising and social media marketing. Keep in mind, the study was sponsored by a provider of SEO services and had a conservative sample size. Despite that, the findings are consistent with what many successful SEO practitioners have known for years.
There are a number of additional studies that have supported the notion that Search Marketing (PPC and SEO) are the most effective and efficient practices for improving website traffic, leads and sales. In fact, Google has compiled a number of case studies and examples of how online search has driven substantial offline sales. Earned, Owned, Paid and Shared Media all drive search as search drives both online and offline outcomes for business.
