Best practice to consolidating authority of several SKU pages to one destination

[french_soc]

I am looking for input on best practices to the following solution

Scenario:

• I have basic product A (e.g. Yamaha Keyboard Blast)
• There are 3 SKUs to the product A that deserve their own page content (e.g. Yamaha Keyboard Blast 350, Yamaha Keyboard Blast 450, Yamaha Keyboard Blast 550)

Objective: - I want to consolidate the authority of potential links to the 3 SKUs pages into one destination/URL

Possible Solutions I can think of: -  Query parameters (e.g /yamaha-keyboard-blast?SKU=550) - and tell Google to ignore SKU query parameters when indexing

• Canonical tag (set the canonical tag of the SKU pages all to one destination URL)
• Hash tag (e.g. /yamaha-keyboard-blast#SKU=550); load SKU dependent content through javascript; Google only sees the URLs without hashtag

Am I missing solutions? Which solutions makes the most sense and will allow me to consolidate authority?

Thank you for your input.

I like Everett's suggestion.

My retail sites have very few pages with a single item.  Most pages have several very closely-related items.  This makes for a more compact site with very rich pages that ranks better in search and pulls in more long-tail traffic.  In my opinion these pages convert just as well as single-item pages (as long as the items do not require a long complex description).

Hello French_soc,

If this were my site I'd have all three model versions Rel Canonical to a single page featuring all three of them and explaining the difference between the features to help the shopper decide which one to buy. It would be like a mini-category page, or more appropriately a Product Grouping or custom landing page.

Does that make sense? Sounds like it was what you planned to do.

Anyone with any input?

With more research it sounds like that the canonical approach would be the easiest (i.e. having pages such as /yamaha-keyboard-blast/550, /yamaha-keyboard-blast/450 etc but setting the canonical tag to /yamaha-keyboard-blast) is the way to go but how well is that supported by all search engines as well as key link prospecting tools such as AHref which play an important part in our process?
