We now have a dedicated SEO strategist who, among other things, develops 90 day plans for our websites. 90 days isn't longterm planning, but at least we have a strategic objective for the quarter. He also works closely with our UX team to identify the target audience - the crew that does the persona research and focus groups prior to the wireframe stage.
Social media. The algorithms have truly changed since social media first emerged. Many content websites are community-oriented -- Digg began allowing users to vote which stories make the front page, and YouTube factors views and user ratings into their front page rankings. Therefore, e-commerce stores must establish a strong social media presence on sites like Facebook , Pinterest, Twitter, etc. These social media sites send search engines signals of influence and authority.
