Sudden traffic down after mobile site

[gkhnrtk]

Hi to all.

I have a huge problem about my web site traffic. We published our mobile site version under mobile domain in m.etilercerrental.com. And we published mobile site sitemap under main site such as sitemap-mobile.xml and notify google from webmaster tools. After a while whole site traffic gone down so badly. Almost 60% gone down which doesnt make sense.

Mobile sitemap is hosted under desktop site. And we didnt add any link to switch sites between mobile and desktop version. We automaticly redirect between desktop and mobile versiyons by detecting useragent.

One another this is we have announcement section in dekstop version but we dont have it in mobile. But we are not making any redirection to mobile site when user visits the announcement section even by mobile phone. Because we are not displaying it in mobile version.
One last this is we are making redirections automatically and  not asking user preference such as showing a link in the bottom of page to switch sites betwenn mobile and pc version.

While developing mobile site we followed instructions in this https://developers.google.com/webmasters/smartphone-sites/?hl=tr

For find the details I would like to give you some site urls.

Site Url                    : http://www.etilercarrental.com/
Sitemap Xml             : http://www.etilercarrental.com/sitemap.xml
Mobile Sitemap Xml  : http://www.etilercarrental.com/sitemap-mobile.xml

How are you handling the google bot useragent, or bingbot?

Hi First of all thanks for reply.

We are using a regex code which is hosted at http://detectmobilebrowsers.com/ to determine whether it is a mobile device or pc.

If a mobile user visits the pc version we are redirecting to the mobile version. If a pc user visits the mobile version of website we are redirecting to the pc version.
