Off page SEO is one of the important factors to build an audience for your website, product or services. Having a product or service but no audience or customers to buy it will not be a worthy business. You have a beautiful house to sell but none of the potential buyers knows about it. what will happen?
That house will convert into an abandoned house. Similarly, if you just right a rich, high quality content but you don’t share it with the right audience, your content will not reach quickly.
Google algorithm is smart. It can identify the good or bad content based on certain parameters or metrics that it follows. You at least need to follow on page seo rules where you write content which Google bots can understand and rank accordingly but at the same time, doing off page for your content can help Google, trust your content more and produce the content to the relevant audience or customers.
