I’m an SEO for an ecommerce site that sells shoes I have duplicate pages for different colors of the same product (unique URL for each color), Conventionally I have added canonical tags for each page, which direct to a specific product URL My question is what happens when a product which the googlbot is direct to, is out of stock but is still listed in the canonical tag ?

Hi guys Just keen to gauge your opinion on a quandary that has been bugging me for a while now. I work on an ecommerce website that sells around 20,000 products. A lot of the product SKUs are exactly the same in terms of how they work and what they offer the customer. Often it is 1 variable that changes. For example, the product may be available in 200 different sizes and 2 colours (therefore 400 SKUs available to purchase). Theese SKUs have been uploaded to the website as individual entires so that the customer can purchase them, with the only difference between the listings likely to be key signifiers such as colour, size, price, part number etc. Moz has flagged these pages up as duplicate content. Now I have worked on websites long enough now to know that duplicate content is never good from an SEO perspective, but I am struggling to work out an effective way in which I can display such a large number of almost identical products without falling foul of the duplicate content issue. If you wouldnt mind sharing any ideas or approaches that have been taken by you guys that would be great!

I found a little difficult for me to do a canonical tag in my PHP. On-Page Report Card We check to make sure that IF you use canonical URL tags, it points to the right page. If the canonical tag points to a different URL, engines will not count this page as the reference resource and thus, it won't have an opportunity to rank. If you've not made this page the rel=canonical target, change the reference to this URL. NOTE: For pages not employing canonical URL tags, this factor does not apply. I don't know how to tidy my PHP Any suggestion.

The concept of using text sliders in an e-commerce site as a solution to placing SEO text above or in between product and high on ages, seems too good to be true.... or is it? How would a text slider for FAQ or other on-page text done with sliding paragraphs (similar but not this specific code- http://demo.tutorialzine.com/2010/08/dynamic-faq-jquery-yql-google-docs/faq.html) might effect text-on-page SEO. Does Google consider it hidden text? Would there be any other concerns or best practices with this design concept? faq.html

Hi SEOMoz! Can I have the rel=canonical tag on a URL page that has a 302 redirection? Does this harm the search engine friendliness of a content page / website? Thanks! Steve

Hello, Most of you heard from the launch of the new format for microdata: Schema.org and my question is about the different types of Schema they provide. Our websites provide an overview of courses, visitors can search/filter training courses and most important: read peer reviews. Until now we formatted (the source) of those courses with the schema type "Product" because it allows us to provide search engines with metadata about reviews via the "Aggregrated Rating". Recently we updated the information about courses, to also provide start dates and locations to users, just like the schema type for: "Events". Because we would like to provide search engines also with both types of data I would like to know your opinion. Schema.org looks like not to support the Aggregated Rating for Events and vice versa for Startdates/Locations for the Product type. And combining the two Schema types also does not looks like an option because we can't put them on the same level like it should be. So what would you recommend to use for kind of schema type(s), are we able to use the 'Product' type next to the 'Event' type and so to combine them? Thanks a lot!

I'm working with a company that has a high page rank on it's main domain and is looking to launch a new business / product offering.  They are evaluating either creating a subdomain or launching a brand new domain.  In either case, their current site will link contextually to the new site.  Is there one method that would be better for SEO than the other? The new business / product is related to the main offering, but may appeal to different / new customers.  The new business / product does need it's own homepage and will have a different conversion funnel than the existing business.
