There are many ways you can promote your website, but before you start advertising your website, though, there are two things you need to do first:
First, install Google Analytics – a free service by Google.
It provides detailed information about the people visiting your site and can show web traffic statistics such as what pages visitors lingered on, what products they liked the most, and where they came from (the referrer). Then, set up Google Search Console – formerly called Google Webmaster Tools, this free toolkit by Google can help you better optimize your website for the search engines.
It provides information like what keywords you’re ranking for and which other websites are linking to you.
