Get a website.
If you're not a tech genius, you can still do this because there are numerous options. Some are free; some are not. Realistically speaking, the free ones severely limit what you can do and you'll find yourself outgrowing them in no time, but if they get you jumping into the website world, then they're worth it.
Some things–like food, water, and air–are crucial to life. When it comes to your marketing life, things like websites are becoming increasingly vital. Tropical Medley by Steve Henderson of Steve Henderson Fine Art.
We pay a monthly fee to Fine Art Studio Online for a flexible, easy-to-use website that showcases the Norwegian Artist's painting art and enables either Steve or me to add, drop, change, alter, play with, modify, or amend our information or images, as well as take advantage of the Search Engine Optimization skills of the technical staff.
On Google, search for "Artist Websites" and look through the various options for marketing your painting art, learning how to sell art online, comparing price, appearance, options, ease of use, and–most importantly for non-techies–support services, and when you find one that you like, see if they have a free trial period and if they do then schedule the time you need out of your life for that free trial period and use it.
This trial period–which is kind of like an engagement–will show you just how easy the site is to use, and just how supportive the tech support staff is, and just how classy your fine art painting work will look online. The proof will be there for you about whether the site's company and service is right for you and your art business.
If you've never done this kind of thing before, there's a learning curve, but as with any new project, you'll get better with practice. But do practice, do keep at it, and don't waste time telling yourself that everyone else can do this but you can't.
If you have a website, how did you settle on it? Are you happy with it? Do you wish for more or different applications? Leave a comment and let us know.
