Authority websites have huge traffic and they drive people with the 'same intention' to your websites. For example – If you are a cosmetic company, it would be a good idea to get keyword rich links from websites and blogs that involve, beauty and lifestyle and fashion etc. You will not gain any stable readership from visitors who came through a camera and photography website.

Always stay focused with your link strategy – It is all about quality, not quantity. Remember one powerful authority link can do the job, which a 100 useless low-quality links cannot achieve.
