A study by HubSpot says that 61% of marketers find SEO as their top inbound marketing priority. Other statistics shared by Search Engine Journal projects that marketers would spend $79 billion on SEO by 2020!
One can say that SEO is the key mantra for web success. Although I am not stating that this is the only marketing tactic. If not SEO then there are various paid options on your hand such as Google paid ads, Facebook ads.
