The names are along the lines of www.keyword1-keyword2.com and there are three that fit for my sites.
I have always been weary of hyphenated domains, do the hyphens cause anyone problems?
Also, would having these domains as pointers really be a help to rankings or are multiple domains for a single site just too much?
(One point I want to add is that one of the hyphenated names is identical to a site above me in the SERPs, if you drop the hyphen. It's not a trademark name either so I don't have to worry about infringement.)
actually, I think the benefit to having a hyphenated domain doesn't come from the domain itself. When most people link to your site, they simply copy and paste the URL onto their pages. If you have hypens seperating keywords in your domain names, it is believed (at least I do) that search engine robots will pick up keywords from your URL more easily, and hence, boosting your site rank popularity for those keywords.
