Not sure where to look or who to ask... for the past 5 or 6 years I've had 2 domains used for one web site;
blue-widgets.com & bluewidgets.com
I had the hyphen name first, then got the oneword name - so my host set it up so that both name point to the one web site - and so that blue-widgets.com/dir & bluewidgets.com/dir go to the same page.
I have had no problems with this, or so I thought.
I just checked my google links and found quite a few good links to bluewidgets.com (blue-widgets.com has 20 times more).
looking closer, included in the results for link:www.bluewidgets.com are some sites linking to blue-widgets.com (no www. with hyphen?).
I then checked a popular link pop reporting site for the link pop of;
None are the same, only a small difference with & without the www. BUT the hyphen / non-hyphen difference is huge.
It's unlikely I can ask all sites linking to www.bluewidgets.com to change their link to www.blue-widgets.com - and its very important that all the directories and pages can be found with or without the hyphenated domain.
Who do I talk to and what do I ask for to make the Internet know that both domains (with & without the w's) are one web site?
