Social may be sexy, but search still pays the bills.

As reported below, organic search drives 51% of all visitors to both B2B and  and B2C Web sites, while paid-search drives 10% (and social 5%, on average). 89% of customers begin their buying process with a search engine.

How can marketers get the most out of search? The search marketing stats and facts below provide some helpful guidance. Here are four key takeaways from this research:

• • Do feed the gorilla. Search doesn’t only mean Google, but the elephant in the room can’t be ignored either. While everyone knows Google is the big dog, the magnitude of its dominance still amazes. Google accounted for nearly 40% of all U.S. digital ad spending last year, while Facebook’s share was about 8%; and Google’s advertising revenue is larger than that of the entire U.S. print industry.
• • Be like Avis. As the company’s iconic slogan went, “When you’re number two, you try harder.” Or rather in the case of organic search, you need to try harder. While it’s great to be #1—the top result still generates nearly one-third of all organic search clicks—the share garnered by results two through four has increased significantly in the last decade. No matter the slot though, the key to getting clicks from any rank below #1 is to craft top-notch meta titles and page descriptions.
• • Get creative. The top challenges in organic SEO are link building (easy-to-get links no longer have much value) and keyword research (the low-hanging fruit is long gone). To rank well today, use a web presence optimization (WPO) approach in order to earn high-quality links from online publications and industry influencers, and write to “be the best answer” to search queries rather than stuffing content with repetitive phrases.
• • Open your wallet. Marketers spend a lot of money online; overall, U.S. marketers will spend more than $103 billion on search, display, social media, and email marketing by 2019—but search will remain the largest share of interactive spend (about 44%). And in PPC search ads, 86% of all ad impressions accrue to the top four spots.
