You will notice if you put your curser over the logos on this page that there are long descriptive phrases. These can be used as text by the search engines but your images cannot. An artist's site is as a disadvantage compared to a text page because the engines don't index your images only the text.
TIP use a different configuration of key words on each page.
If every page has the same key words, they are all as if one to the search engines. Dream up every imaginable key word combinations that you can think of and this will make your page show up under a more diverse range of searches. TIP Search for web pages like yours and then study which ones are in the top twenty. Look at the page titles and page descriptions. There are often what carry the most weight.
