A search engine like Google uses an advanced algorithm to rank the web pages for their searchers. However, those algorithms will still require your assistance in order to correctly analyse and rank the content of your web page. If your content is not optimized, then the search engine will fail to rank your website and it won’t appear in the search result… …as a result, you will miss out on all of the visitors to your website. So it is really important to do SEO for your website.
