How do I best proceed if I don't find any id tags upon trying to rip a cd?

So far it seems to me I have to add all information in the meta id tag field in the cd ripper.

After ripping I guess I best submit the information to free db so that it can be retrieved by others.

Is this the easiest to do so or are there better ways?

And how do I proceed if I have ripped a CD without adding any information. - Is there any way that is better than adding the information for each track in the poweramp converter?

Thx for help.
