From a statistical perspective, link building still ranks as a heavily-weighted factor for authority in search engine algorithms. Backlinks help to provide a vote of credibility and authority that other sites find your content assets valuable and worthy of a link. However, link building is certainly not everything when it comes to search optimization. To use the oft-repeated cliche, "content is king!" But, high quality backlinks are important for content as a balanced way of showing all the right signals to search engines (not just link building) for organic online exposure and revenue growth for your business.
