Sometimes grants are available for entrepreneurs to market products and services (check with your local Council or Chamber of Commerce). The grant will usually, in part, be payable to a marketing service. If there is no grant, how will you finance building your business and how do you prioritise?
If you reach the conclusion that building traffic to your website is the best way to go, your attention will turn to SEO (search engine optimisation for your website), advertising (e.g. with Google Ads) and, importantly, social media. (Usually, at this point, many people declare their dislike of sharing photographs of food, cats, selfies, etc.). It should be noted that social media for business purposes is approached more professionally. LinkedIn and Twitter are the top choices for B2B, Facebook for B2C.
Basic SEO should be part of your website development so choose a company or service that recognises this and, at the very least, provides you with the tools to continue producing great content.

There are cheaper options, such as a short burst of Facebook Ads to boost your followers as you use social media to engage with them and direct traffic to your website. Find out more about using social media for business. The Google section covers three very useful topics.
