After many years online, we simply do not know how many online business directories share our contact information, but we do know that the numbers probably run into the hundreds. Most of them are of little value, and the probability of winning any real business through a directory registration is likely to be similar to the probability of winning a National Lottery.
However, to use a football saying, ” if you don’t shoot, you won’t score goals”, so our advice is to register with directories which offer some kind of human-human contact option, or which declare full contact details including a verifiable street address. Directories will inevitably share your details with their partner network, and their partners will do the same. Let the directories do the work for you, because monitoring their effectiveness will steal much of the time that you need to spend building your business through other more conventional activities.
