I think the prices are reasonable, but the web stats are showing that the site definitely needs more visitors, which of course may be the major reason.
Some things to consider about this site.
1. There is actually plenty of content.
2. No meta tags are used, and all the 'page titles' are the same.
3. When doing a web speed test from http://www.websiteoptimization.com/services/analyze/ , the total size,etc was shown to be a little bit excessive. Is this a minor factor, for example, if the page size is too large, visitors on dialup may not want to wait for the large images to load (we can consider thumbnailing the images on the individual products page).
4. When trying "site:arts-biz.com" on Yahoo, MSN & Google, the results were 13, 406 and 690 respectively, but this doesn't really mean much does it, because a few page rank tests returned a zero value ? Notice the page titles in some of the searches were all the same, is that regarded as duplicate content ? Surely the site would be better off with page titles that reflected the product name,etc.
5. No doubt spiders parse through each page content in the same order as the source code is generated, and the left hand column info box 'headings', such as "Categories. Artists" seem to be giving duplicate content, as shown in the Yahoo search on the site. Is it better to re-arrange page layout, so the _real_ content appears first ?
6. Will adding the site to Dmoz help ? What about submitting the site to other search engines, presently these are the ones that crawl the website:
7. There aren't many links on the site; how much will adding extra links help ?
8. The site was originally going to have content in other languages, like:
will adding the above language content help more people 'find' the site.
9. No doubt the site itself, selling oil paintings is something very 'common', and that in itself, would make it difficult to get a high PR, etc., in effect more competition, because 'art' and 'paintings' return millions of hits from search engines.
Any other tips or advice would be very much appreciated.
