Link building is a catchall term for the practice of creating new external links to your site. Beyond creating great content people want to share, guest blogging and asking webmasters from authoritative sites relevant to your business to link back to your pages are great ways to build links. When possible, use keywords are the anchor text for your links, as this will help send signals to Google that your pages are relevant for those terms.
At our agency, we work with sites of varying sizes, from very large to quite small, and recently, we have noticed a trend at the enterprise level. These sites aren’t relying as much on Google for traffic any more. Not only are they not relying on Google traffic, but also, the sites are getting less than 10 percent (or slightly more) of their organic traffic from the search giant.
