Hey there Deesignsbydee,
This is probably one most asked questions in the universe - since you do shows, hand out business cards and/or flyers with your website details to anyone who stops by, offer something extra if they purchase online - free shipping is always a winner. Having your own Domain name can be helpful as you can then have your own business email address too. More professional than say Hotmail, etc.
You need to experiment with different strategies and track your results to determine what works best for your business. Start with Social Media: Social media can be a great tool for promoting your website and increasing sales. Creating engaging content and sharing it on social media platforms can help you reach a wider audience and drive more traffic to your site. Start with the basic social media sites, Facebook, Twitter, Instagram, Flicker, Pinterest, Google Maps, Google Places for Business and Yelp - the more you get your name out there the better and you can setup these accounts at little or no cost - it's just your time. Take your time and take lots of product pictures or provide detailed info about your services if that applies.
Advertising in your local paper may promote sales too. Cross selling via other sites like Etsy may increase interest even if you just list a few items.
Creating high-quality content, such as blog posts and videos can help attract and engage potential customers, leading to increased sales. Both Youtube and Vimeo are great for posting product or service videos at little or no cost. All you need is a camera, some thought and a little time.
Email Marketing can be great but, don't spam, else you will negative feedback. Building an email list and sending targeted campaigns to subscribers can help you stay top of mind with potential customers, leading to increased sales over time. Make sure your list of addresses is composed of people that want to hear from you.
Pay-Per-Click (PPC) Advertising: PPC advertising allows you to place ads on search engines and other websites, targeting specific keywords and demographics. This can help you reach your target audience and increase sales. Note: It's a challenge to determine your ROI when spending money on advertising - choose wisely.
Search Engine Optimization (SEO): Optimizing your website for search engines can help improve your website's visibility in search results, leading to more traffic and potential sales. This can involve on-page optimization (optimizing website content, tags, etc.) and off-page optimization (building backlinks, guest posting, etc.).
Take advantage of Google Webmaster Tools and Bing Webmaster Tools.
Finally - word of mouth is your best friend - try to friends and family involved - people trust people they know (in most cases) and this type of advertising is FREE.
Just some thoughts ....
