Does setting up a Dudamobile page affect my SERP?

Hey there,

My site is hosted at yahoo, i've used sitebuilder to build it.
I run a pest control business and I have individual pages for each suburb.

I have got 465 suburb pages and 367 of them are on page1 ranking of google , the latest one I managed to finish yesterday. I'm still working on the other pages (I try to do 5 a week)
this is both on smartphone, tablet and desktop searches.

My site is not setup for mobile.

My question is: if I setup a dudamobile site with redirection, will it affect my SERP?
I need to cut a little of my content out to make it tidy on duda, I've only just started building it.
I dont want to have to start my SEO all over again.


Thankyou for your help

It will absolutely affect your ranking, redirecting your site to a new site with most likely different template. You should make your site mobile-ready without completely switching to a new platform.

Some simple .css styling will make your current website mobile-friendly -- it will preserve your rankings if you're just modifying CSS.

100%, without a doubt, no question about it will change your rankings, most likely for the worse, if you take an already-ranking site and 301 it to a completely different platform.

Just to add to that, I wrote this explanation of how switching templates will mess up your rankings back in 2011 ...

And the reasons behind it are just as valid today as they were back then.
