where can i advertise my jewellery site?

Polite, useful comments with your link included on blogs and forums discussing your field and on social bookmarking sites are tolerable ways to earn a tiny bit of search engine rank. You can submit to directories, though the golden age of web directories is long past, some still may improve your ranking.

You can find services on webmaster forums that offer to make numerous directory submissions for around $10.

I recently read about someone with a site in the competitive jewelry field who bought $500 in PPC traffic without getting one sale, it's tough out there competing against the monster sites.
