Best practices for structuring an ecommerce site

[pherbio]

I'm revamping my wife's ecommerce site.  It is currently a very low traffic website that is not indexed very well in Google.  So, my plan is to restructure it based upon the best practices that helps me avoid duplicate content penalties, and easier to index strategies.

The store has about 7 types of products.  Each product has approximately 30 different size variations that are sometimes specifically searched for.

For example: 20x10x1 air filters, 20x10x2 air filters, 20x10x1 allergy reducing air filters, etc

So, is it best for me to create 7 different products with 30 different size variations  (size selector at the product level that changes the price) or is it better to create 210 different product pages, one for each style/size?

People do both.  They will search for particular sizes as well as general broad searches and then once on the site, drill down to their particular size.

Here is what I think about this!

If people actually search for specific size then my idea is to go with 210 different products as it will be easier for one to rank in search engine for specific size.

If people search for products name in that case going with 7 different products and offer different sizes on the product page.

Hope this helps!

Thanks for the response.

I was leaning that way simply because unique content would be so much easier.  Plus, the management aspect of 300+ unique pages would be a pain to deal with.

The chances of the product page getting inbound links is better if the size variations are on the same page. That way if someone links to you as having air filter 10x20x1 you could also get a link to that page from a person looking for 10x20x2.

On the page itself you can have pictures and copy displaying the various sizes. With how much Google clusters based on similarity you're better off with as strong a page as possible versus lots of low strength ones.
