If there are enough reviews on a product page to warrant page 2, 3 etc, BazaarVoice appends the below snippets to each new page of reviews, which are then also indexed, despite BazaarVoice SEO settings that automate a canonical tag (seemingly since the differing reviews on each page are not similar enough to honor the canonical).

• <cite class="iUh30">?bvstate=pg:2/ct:r</cite>
• <cite class="iUh30">?bvstate=pg:3/ct:r</cite>

It seems Target.com has found a way to hack the BV code to create a dedicated page to view all reviews:

• https://www.target.com/p/ultra-soft-fitted-sheet-300-thread-count-threshold-153/-/A-13973172?showOnlyReview=true

While Ikea.com blocks it in the Robots file (defeats SEO value) -

• Noindex: */catalog/products/bvroute=Review Noindex: */catalog/products/bvtab

Tons of brands apparently have the issue, and you can see more examples if you search "inurl:bvstate=pg"

Anyone aware of a solution to this?
