Not wishing to be contradictory, and knowing nothing at all about Wix.com, but the site does seem to be constructed with HTML Meta tags, which the search engines should pick up.
Having said that these Meta tags should contain your keywords - i.e. those words other people will use when searching for your site. It's not those that know who you are that you wish to attract - it's those looking for a photographer in your area.
The background code reads,

I'm guessing that you have some control over the Keywords and Description tags. Use the Keywords tag for, er, Keywords. Then scatter those Keywords into a sentence or two for the Description and Title, with your most important Keywords at the start of the sentence.
