Redirect From .aspx to .html if already indexed - Website Redesign

[DavidZA1]

Hi Guys

I would like to know if somebody could possibly shed some light on this for me.

We are in the process of re-designing our site, but we are keeping all of our content in terms of site structure, internal linking etc. the same.

Now we were wondering if it would be a SEO best practice for us to change our pages' extension from .aspx to .html and just put a re-direct from the aspx to the html pages.

Or should we keep everything as is, and maybe just revise our on-page seo efforts as well as do some more link-building.

I just have to note that we are currently ranking very well for top positions and obviously all these pages are already nicely indexed.

And then another question I have is with regards to our mobi site of this same website.Our dev team created it using Responsive Web Design, but they decided to implement techniques that show and hide content based on what device you are viewing it on.

So when viewing it on your desktop, it will show content as per normal, but when viewing it on a mobile device it will hide this content and show the content formatted for that specific mobile device.

So we are obviously sitting with a case of dup content here.Is this technique acceptable, or is there a workaround/different way of implementing this?

Thanks In Advance

Dave

changing .asp to .html won't help your SEO so i would just leave it alone.

if you were going to deal with extensions i would lose the .asp and not have any extension.
