I have an oscommerce website. It was recently updated 12/07 and since then it is quickly dropping in the organic searches. Before the update it place in the top two on the main page, now the site is moving down.
One thing I notice in looking at the source code that the meta tags did not have anything relevant to my site - it just said LAMB Product, Inc. I added the relevant keywords to my meta title tag on 01/23/08, however it will not allow me to customized keywords in my meta keyword tag or meta discription tag. My current web designer claims this is a feature that cannot be changed.
If you can modify this or implement this feature please notify me.
