one of our clients has some 2000 used and unused domain names and is looking for ways/ideas to generate income from those names using advertisements, referrals etc.
the domain in particular is 2 char dot com name 75/com that has many unique visitors without any use of advertisement. They added recently 2 adsense from google and it is generating income less than 500/month.
is there a (free) way or how can we find out what adsense keywords pay what revenue?
google offers projected number of clicks and cost per click for a keyword for google ads, but they dont offer how much a particular keyword is bringing in for google adsense.
what would you do on 75 dot com to generate (additional alternative) income (since it is currently an informational yet no-income generating service website?)
a.) adsense techniques? or/and
b.) offering users to create a pop3/webmail email address and charge a per month fee? or/and
c.) forwarding all unused domains to that domain?
d.) what would you do?
