do we need a high traffic to sell domain?

[Dani]

how about a new domain with parking ads and low traffic?

[Thomas]

High traffic is good

[Jake]

Traffic is more important if selling both a domain ans site combined, where the buyer may want an established business.

An aged domain that has not expired is a big plus, those with backlinks may be as important as traffic.

More often domains are bought for their branding value or match to a particular sort of business, and the pricing is rather subjective.

Yes traffic visitors is must for generating your lead online, but visitors should be industry relevant.
