Backlinks build your websites authority
An effective SEO campaign uses variety of techniques, and probably the most important of these is link building.
Backlinks are the links on other websites that direct people to your own web pages. Having plenty of high-quality links suggests that your site is a genuine source of interest or authority. For example, if you sell baby products, then having popular parenting websites link to you is evidence that you’re offering something valuable to NZ and the world.
