We do not submit press releases. It is a waste of time and resources, and we don’t do social bookmarking or directory submissions, for the same reasons and in addition because it is ineffective, time consuming and not really worth the time or the efforts.
The only type of directory that has any point is a directory that is ranking high on Google for the specific terms, but all others are just waste of time and money.
The point is, massive submission to directories is pointless, because Google long time ago has discredited the value of links in those directories.
If you think that this piece of information is not correct, or someone managed to convince you otherwise, the issue is very simple, ask this person to prove it in a practical way. At the end, you will find out whether or not you have wasted your time and money or not.
