Tip #1: Mobile. Google is going all in with mobile. Do the same. My latest Search Engine Land piece goes into some detail on how you can optimize for mobile users to gain a strategic advantage.
Tip #2: Don’t look at SEO in a silo. SEO best delivers as part of a marketing campaign that looks at multiple tactics: SEO, SEM, Social, Content, Paid Strategies (content and social). Find the perfect blend of tactics and strategically integrate them for better SEO and better results all around.
Tip #3: Think beyond commercial keywords. The majority of search engine users start with a question. Answer those questions. Make your content marketing stand out from the ever-growing crowd. Think of SEO as a list building and lead acquisition exercise and not just sell, sell, sell.
