I have quite a few sites that nearly ready to go with link building, and many more lined up, but before I do I wanted to get grab some last minute opinions on WWW vs no WWW I know that you want to stick with one and not switch as they count as two separate sites. There doesn't appear to be a positive SEO effect either way, so the real issue to me is aesthetics in the SERPS and any implied trust or other factor that could potentially increase or decrease CTR. Right now I only have WWW on short two keyword sites, and have removed it from the longer 3/4 keyword domains. My thinking is that for shorter domains, having www connotates more of an authority site, but for long 3/4 word domains it's just unnecessary clutter. And although its small, removing the www means your bolded keyphrase is that much closer to the margin and amidst a sea of WWWs. Significant? Probably not as much as the combined clumped bolding in title, meta, and url. Thoughts?
