I'd love to see how the presence of a phone number affects web-only conversions.
It is psychologically reassuring to think you will be able to call if you have a problem.
Now does that actually mean I buy from newegg more often as a result? Who knows ;)
Nice looking Web 2.0 websites just look reliable, so I don't check for phone numbers on them. The older the page looks, the more i look for a number.
Well, in those cases, neither make their phone number easy to find. Amazon has it hidden very deeply in their "help" site, and eBay requires an account to get at their number. I assume, anyway -- I browsed for a few minutes and didn't find any phone numbers at all.
Big companies prefer email just as much as small ones.
