Welcome to the Q&A Forum

A client's site where both the www. and non-www. versions are both being indexed.  The non-www. version have has roughly 1000 or so links where the www. version has over twice as much pointing back to the site.  In addition, the www. version has higher domain authority. Their programmer has suggested that they can't implement 301's permanent redirects across their site for a few reasons. My question is, what would be the best alternative to block/redirect the non-www. version from being indexed yet still pass link-juice?

I have a client that wants to setup wordpress for their business site.  However, they are really concerned about the load time a wordpress install creates on their site in the root.  So, they want to setup wordpress with a sub-domain on a separate server.  For example: abc.domain.com As far as SEO is concerned with the main site, what are the advantages and disadvantages for using a separate server w/ subdomain?
