I am having a bit of an issue right now with some of my product listings. Right now I have about 3000 product listings on my site. All the content for them is unique and written by me, but I think google might be starting to punish me for duplicate content and when I say that I mean duplicate content on my own site..everything is unique to my site so I am not worried about duplicate content from the rest of the web.
Basically each product gets its own URL, but I have a few product groups that have three or four hundred listings but with all the same description, basically the part numbers are what differentiate them. So we will take rubber washers for example....I have 400 different rubber washers:
Rubber Washer #33456 1/2 inch
Great rubber washer, high impact strength
So imagine that three or four hundred times with just different part numbers. At first google was indexing every one of these pages, but now all of the sudden they are not.
How can I tackle this moving forward? Is there a better way to structure my pages so that google will still find all the different part numbers?
Is it best to have one singular page for "rubber washer" and simply have a select box with all the part numbers? My main concern is keeping my high rankings for individual part numbers.
Thanks for any help
