Writing for the search engines is a fool’s errand. Yes, we do need to be technically proficient in developing the site and content for SEO, but if you create content that real live humans will want to read and share, SEO will follow. Social sharing is such a big part of the indexing formula today that your focus should be on creating great content for the site – content that people will want to share.
Building a strong and trusted social media profile will help your SEO. Your influence increases the value of the content you’re sharing, so make sure your social media presence is top notch.
