What is duplicate content and how can I avoid being penalized for it on my site?
The website is a Magento store , but I believe this applies to any product search.
We have a search form which takes several parameters. Each combination of parameters results in a different set of products being returned. Obviously sometimes the same product will appear in a different set of products.
Very little changes outside the products list when we filter the search: the title tag and the filters lists, the one major change is the product list, where some products will disappear, but most of the time they will repeat through different filters. Also since we have different urls the search engine is treating them as different pages.
Is this considered duplicated content?
Also what is the best way to make my search seo friendly?
Listing all my products and using the canonical tag to point every search there is an option, but is this the right choice? Aren't I losing the possible keyword combinations from my filtres (category, price range, brand)?
