how much I can get for my domain which is from two keywords without dash between them and it is .net with 3 400 000 exact searches I do not want to name it I'm just asking if someone can name a price
You mean keyword.net or Keyword1Keyword2.net? If the first option then your keyword might be worth a lot but it heavily depends on niche. Exact match keyword related to Justin Bieber won't sell for anything because you can't make any money from such traffic. If this domain is in insurance, web hosting, finance etc niches then it is worth a lot. You should give some more information before we can come up with at least some valuation. You can also check it on estibot.com because they analyzes the value of your keyword such as monthly searches and CPC. For further evaluation we need: - Age - What is on .com .org domain names - Niche
It actually depends on the name. If you could PM me the name I would be able to give you rough value.
