What you think if a domain recieving 10,000 plus users per day and its name for example is abc.com and if I register abc.net or abc.info , is it valueable and can I earn some money from domain parking like sedo and from search engines traffic by getting some domains like this method. ? Plz also suggest which one is better .net or .info. Thanks.
I do not think it holds any value just coz the other tld is so popular. well if you register google.net you might get some type-in traffic
Most people assume that a website is .com anyway so you may get the odd typo results but I wouldn't waste the money in my opinion.
i agreed that you will get problem about legal issue if you just use the same domain with just different ltds and show similar content to steal their customer. it's better to build one with the same niche but different domain name.
