Duplicate Page Issue

[DigitalJungle]

Dear All,

I am facing stupid duplicate page issue, My whole site is in dynamic script and all the URLs were in dynamic, So i 've asked my programmer make the URLs user friendly using URL Rewrite, but he converted aspx pages to htm.

And the whole mess begun. Now we have 3 different URLs for single page.

Such as:

http://www.site.com/CityTour.aspx?nodeid=4&type=4&id=47&order=0&pagesize=4&pagenum=4&val=Multi-Day+City+Tours

http://www.tsite.com/CityTour.aspx?nodeid=4&type=4&id=47&order=0&pagesize=4&pagenum=4&val=multi-day-city-tours

http://www.site.com/city-tour/multi-day-city-tours/page4-0.htm

I think my programmer messed up the URL Rewrite in ASP.net(Nginx) or even didn't use it.

So how do i overcome this problem? Should i add canonical tag in both dynamic URLs with pointing to pag4-0.htm. Will it help?

Thanks!

Yes, adding canonical tags will help. Or just 301-ing the other URLs to the SEO-friendly one.

Depending on how many pages your site has, I'd either just add canonicals to the pages, or check if your programmer did indeed not use the htaccess - which you can then always mend.

Also have a read through Dr Pete's post here: http://www.seomoz.org/blog/duplicate-content-in-a-post-panda-world which is probably the only duplicate content post you will ever need to read to fix any problems.
