There are many types of black hat SEO, but they all have one thing in common. The intent on rankings without regard for what’s best for your website or business. Google has widely condemned this practice as it can cause significant problems down the line, with low-ranking sites ranking higher than yours. Also, potentially hurts traffic numbers too much if left unchecked long enough. The consensus seems to be that quick gains through unethical means will get you nowhere fast. So why would anyone do something like this? Nobody knows because there isn’t any tangible reward beyond some temporary satisfaction from overcoming obstacles.
