If you have any reasonable traffic names, make them into mini-sites and you shalt be well rewarded. I have found adsense a step up from any domain parking company.
Ultimately, SEO all boils down to getting quality links to your website. The rest is figuring out how to get those links, which isn't necessarily easy.
Google now has a way of parking domains. The domains show Google advertisments. The owner gets revenue for clicks. Their system cuts out the middle-man, like Sedo etc. Their system is called something like 'Google for domains.' I can't say it generates much income. It's worth a look.
G'day Ed,
You helped me out a year or so back when we spoke on the phone as I was acquiring some names. Thanks for that. I own a pile of .In names but wonder if they're worth renewing later this year. I don't have the time to develop, more interested in holding until the .IN thing grows and then selling. These are some of mine - any thoughts on whether they're worth keeping? tenniscourts.in - artdealer.in - fourwheeldrive.in - wealthcreation.in - hirecars.in - plasmascreens.in
