Paul,
Ive had good success with the same JP ad over the last two years. No one is suggesting its the Bee's knee's and and couldnt be bettered. But JP stuff does work its a fact, and gets the most criticism from people who wont put their hand in their pocket to invest in their business in this way. Why they get so het up with people who do take the chance, is beyond me.
These ads along with a lot of the other JP stuff are tried and tested. One of the most unusual aspects discovered is that if an ad looks 'Pretty' it is unlikely to work. The YPs style ad, like you, most of us that use it, would agree that we dont really like the look of it - but it works! Some have changed it to make it look better, but results have not been as good and after reverting to the same awful looking one, response has picked up again. Perhaps the reason that it is so successful is that it is different from the usual - Name, rank , number that almost everone else seems to follow - business owners like to see their company name up there as big as possible. However the JP phylosophy is that the message is more important than ego.
Dave.
