4 words dot com with around 1000 exact matches. Should I register? Eg.- usedcarsforsale.c0m

It depends upon the name itself. For example, if its zerointerestcreditcards.com with good lead generation potential, you can register it and develop it into full fledged businesses.

BTW, if its a new name, you can register it via godaddy and use $1 coupon codes. In this way you can lower your risk of spending 10 or 15$.

Also, can you share other stats like CPC, advertisers for that work?

cpc is around 2$.
Exactmatch- 2300(estibot)
Valuation-220

P.s - I dont have creditcard for godaddy

If you are based in India, you can buy godaddy .com domain for Rs189. Just create a new godaddy account.

I am from Nepal. .I have paypal,but neither godaddy nor 1and1 accepts paypal for promo offers. .
Are there any other solutions?
