you've been here for like 2 weeks. it can take months and up to a year to be seen in google. and you have to have plenty of links coming in from many pages related to the art your selling. have social media accounts etc.
and while nice looking, you only have 52 images, so you won't stand out from the crowd.
you have practically no keywords on this.
iceland landscape sheep stream that isn't enough. how would someone find this based on 4 words? if you want to be seen you have to describe everything. its a ranch, farm, Icelandic, animals,grass etc fill it up. the descriptions come across like you stumbled on them while driving. a neat sunset, this scene, describe what we are seeing in general.
tell us about the bird. tell us more about it in keywords as well.
people don't stumble onto images, you have to give good descriptions, clinical views of whatever it is we are looking at so google can catalog them. and the keywords are important. more so, the view count suggests your not advertising it either. google won't just find it, you have to do something too.
as for this site, the search sorts by how well you sell, how popular you are etc. and you need keywords.
If you want your images in a Google search on certain words, then use those words in the title and description so the internet search engines can index your image. Indexing is not instant and when they come knocking be ready with full descriptions and descriptive title using the words you think your buyers would use to find the art. That would be subject, location and style. If you want to rank high on those words it helps to link the page to other sites. There is a lot more to being ranked, but Google keeps it a secret. Most say longer descriptions get ranked better.
Here is my "checklist for success" in print sales.
google likes descriptions that answer questions. but they can't be lifted from wiki, even though many do it. just a simple paragraph or two is enough. google has like 200 or more things to follow, many of which we can't do on this site.
