Welcome to the Q&A Forum

Hi Mozzers, First time poster here, enjoying the site and the tools very much. I'm doing SEO for a fairly big ecommerce brand and an issue regarding internal search results has come up. www.example.com/electronics/iphone/5s/ gives an overview of the the model-specific listings. For certain models there are also color listings, but these are not incorporated in the URL structure. Here's what Rand has to say in Inbound Marketing & SEO: Insights From The Moz Blog Search filters are used to narrow an internal search—it could be price, color, features, etc.
Filters are very common on e-commerce sites that sell a wide variety of products. Search filter
URLs look a lot like search sorts, in many cases:
www.example.com/search.php?category=laptop
www.example.com/search.php?category=laptop?price=1000
The solution here is similar to the preceding one—don’t index the filters. As long as Google
has a clear path to products, indexing every variant usually causes more harm than good. I believe using a noindex tag is meant here. Let's say you want to point users to an overview of listings for black 5s iphones. The URL is an internal search filter which looks as follows: www.example.com/electronics/apple/iphone/5s?search=black Which you wish to link with the anchor text "black iphone 5s". Correct me if I'm wrong, but if you no-index the black 5s search filters, you lose the equity passed through the link. Whereas if you canonicalize /electronics/apple/iphone/5s you would still leverage the link juice and help you rank for "black iphone 5s". Doesn't it then make more sense to use canonicalization?
