We have a webpage that handle all car manufacturers. Page is called vehicule.aspx.

We have a rewrite method for SEO purpose. We gave all manufacturers a unique URL that redirects to the above page.

E.G. www.example.com/Audi.aspx will redirect to www.example.com?a=Audi

Problem is that in Google Search Console (webmaster tools) I see these 2 pages have duplicate meta tags. I use httpcontext.rewritepath to redirect the user. I can't find a way to set this redirect as "canonical" or something that would make this duplicate disappear from Google Search Console (webmaster tools).

There is nowhere we are referencing ?a=xyz. It's all done internally so I don't know why Google sees this a duplicate.

Any input about this?

  • "redirect" / "done internally" - so is this a "redirect" or a "rewrite"? Are you sending an HTTP 3xx status code? Perhaps just a niggle, but you state "redirect to www.example.com?a=Audi", but state that the "Page is called vehicule.aspx"? – MrWhite Mar 4 '16 at 17:48
  • yes it's a rewrite. It's done in c# and it's a HttpContext.rewritePath() msdn.microsoft.com/en-us/library/… – Yannick Richard Mar 4 '16 at 18:16
