Hi. I have a site which was using Non-www domain as a prefered domain. 1. If i change the prefered domain to WWW by following the guidelines such as 301 redirection and selecting prefered domain from Google Webmaster, Would it hurt my seo ? 2. Should i select GeoTargeting country , Crawling rate and submit the sitemap for both www and Non-www domains or just for the domain that i will use as a prefered (www ) domain ? Sorry for poor english.
I would likely keep the url structure. Whether you have www or not is simply a personal choice. That said, changing it is fine if done correctly with htaccess and webmaster tools. You may notice a bit of a hickup but nothing to worry about really. Hope that helps, Nigel
And what about the link juice ? I have too many deep backlinks to non-www. Would they pass to www with 301 redirection or ?
Yes, basically everything will roll over to the new version. That said, if you have a ton of inbounds it is still a better idea to keep them the same but the answer to your question is yes essentially. Nigel
