For Buyonlineshoes.com say a low XXX figure. If it had been say buy shoes online or shoes online it might have had higher value according to me
For documentmanagement.info this might find value with document management companies. Would have had good value if it were a .com domain but considering it as a .info domain may be a low XXX
For winterdresses.info dont see much value as its a plural - say even winter dress might have had some value but I guess people wont search for winter dresses but would rather search winter dress.
Thats my feeling regarding domains and values and I might be totally wrong
With winter dresses I registered it because of the search results in Adwords Keyword Tool:
It has for all countries this search results per month:
Broad: 165.000
Exact: 8.100 (High competition)
