I have a single wordpress site for 2 years. Is functioning with the 3 w’s (www.mysite.com), and I will move it to a wordpress multisite. As you know in wordpress multisites they don’t have the 3 w’s as default (mysite.com). In alexa.com I have a good rank and some backlinks to my site. In google web master tools, in configuration > settings > preferred domain the option don’t set a preferred domain is checked all this time, and in google my domain is with 3 w’s. Should I choose the option display URL’s as mysite.com? Am thinking my site to be without the 3 w’s anymore in the multisite. If someone who works SEO I would like to his/her opinion about it. Will it affect my rank on this site? If yes what do I have to do If I want it to be without the 3 w’s without affecting my rank?
p.s my cached url in google is with 3w’s
