Does google pick up on code names?

Hi Nicolas,
With regard to my record shop at www.acrossthetracksrecords.com,I have been looking at ways to increase its position in google. I realised that I had not included the word vinyl very often at it is probably the most important keyword for the site. So, I was trying to think what heading I could add to my CSV files. I sell mainly Vinyl LPS, but also CDS. So, I had thought of adding a product_code heading and giving all items in say, the jazz category a code of jazz vinyl 1, Jazz vinyl 2 etc. So, I gave it a try, and see that the code does not appear on the description. So, I was wondering if google would pick up on it? I also tried product_type, but this again did not show on the actual listing, so I was again not sure if it would be picked up by search engines?
Please can you advise, or perhaps suggest a different heading?
Many thanks
Sarah

Hi
Thank you. We have already put it in those places, but a look at google analysis says it has not picked up on the word vinyl. So I thought it would be good to add it to other places.

Thank you for that suggestion, we will do that.

Just for interest, Google doesn't use the meta keyword tag googlewebmastercentral.blogspot.com/2009...ywords-meta-tag.html

Hi
Thanks, that is what I thought, and had read that post, but I am sure some search engines do. Google seems to pick up the meta descriptions well. I am going to add key words to titles and see if that does the trick.
