It really depends upon what type of website you have in order to tell you which way would be the most effective for your particular type of website and business.
But, I start out all of my marketing clients by doing these four things.
- Create and optimize their Google My Business account.
- Create and optimize their business information through Moz Local.
- Create/Claim their Facebook Page.
- Hook up a Google Analytics account.
These three things combined will make your website and business more accessible to the public and increase your localized rankings by taking a NAP (name, address, phone).
Once you have these three things set up I would highly advise you using new online software that I currently use for all of my customers called DIIB.
DIIB provides an analysis of your website and combines the stats from the four steps I outlined above to give you easy step-by-step directions on what you need to do to bring more traffic to your website.
After that, I would write original content that helps your visitors that is related to your business/website. Then share your helpful content to social media accounts like Facebook, Google My Business, Instagram, etc.
This is the best starter/base way to initially drive traffic to your website. Then if you want to dig deeper than that I would need to know what type of website you have, what type of business you have, what your goal objectives are, etc. so that I could give you better specifics on how to do this.
