We are trying to run a vwo test for our pdp page.I created a test in VWO where URL www.example.com/products/productid will get redirected to www.example.com/productid?isVWOVersion=true for 50% users.

Based on the request param isVWOVersion I will decide whether new PDP content needs to be displayed vs old one.

Below is the jsp structure -> index.jsp -> isVWOVersion = true then include pdpNew.jsp else include pdpOld.jsp

Will my SEO ranking get affected? Does Google sees two versions of PDP as duplicate content? Do I need to add noindex meta tag <meta name="robots" content="noindex,nofollow"/> to pdpNew.jsp to avoid SEO ranking issues due to duplicate content?

  • Hi Stephen, i deleted the other question. Does google treat www.mysite.com/productid?isVWOVersion=true and www.mysite.com/productid as two different urls and will see them as two pages having duplicate contents causing SEO ranking issue?

  • Yes, those are two different URLs to Google.

  • Thanks Stephen. so that means i will need to add a no index, no follow meta tag on jsp corresponding to www.example.com/productid?isVWOVersion=true to avoid any duplicate content issues.

We've run split-URL tests like this ourselves, and haven't seen any fall in SERPs. Some customers had lingering doubts, so here's what we did after scouring the web:

  • Choose two pages; the control and the variation
  • Add canonical tag to both pages... pointing to the control page
  • Run split test for 17 days

Result: The control page did not fall out of Google rankings.
