Domains having zero parking revenues?

[timewo]

I have a large number of short domains and they are getting some visitors daily, but both the parking companies are not paying anyone for the visitors despite showing ads. In this case, is there any way to make some money?

There are a few reasons why domains may generate no parking revenue:

1) Domains with very low/no traffic or type-in traffic will not earn anything since ads only pay when displayed and clicked by visitors.

2) Domains with names unrelated to commercial keywords have less advertising relevance so may show fewer or no ads.

3) Domains associated with content conflicting with advertiser category restrictions can be exempt from showing paid ads.
