Black hat SEO is aimed at "cheating" the search engine algorithm and make Google think your site is valuable and authoritative. Black hat methods include buying links, using link farms, spamming forum/communities, and comment sections. Thus, if you're intrigued by taking shortcuts and using black hat strategies to promote your site, think twice before going that path. Even though such deceptive strategies may offer rapid traffic improvements, they come at a high cost in terms of your business reputation. That's why you should aim for a fulfilling and long-lasting impact with white hat SEO.
