I have been operating an ecommerce site for just over a year now. Prior to that, we sold the same items just on eBay. So now we sell both on eBay and on our personal site. We have one basic product (hand dyed fabric), but about 150 different color variations of the product, so we have a page with color photography for each item.
Sales have more than doubled over the year, so we're happy with that result. However, we still have a Page Rank of 0. Even with that 0, we're showing up between 11 and 16 on the Google SERP for our most important keyword on most days, so we'd like to bump that up a few notches to get on Page One.
Judging from Webmaster Tools, the only problem listed is Duplicate Meta Descriptions. Not sure how to overcome this, since all 150 items are the same product, just with different colors.
Also, we have keywords designated for each item, but of course they're nearly all the same keyword (since they're all the same product).
I think I should do the following (and I'm looking for encouragement or discouragement before I do this):
1) Relate all 150 product pages via canonical link to the home page of the site, so that the only relevant keyword link is to that home page.
2) Rewrite the 150 product descriptions. First, eliminate 3/4 of the content which is absolutely the same (i.e., shipping policies, return policies), and just provide links from the product page to the policies page elsewhere on the site.
3) Still not sure what to do with the duplicate meta descriptions, since all the products are the same thing. Suggestions?
Many thanks for your thoughts.
