If a lunatic had a gun to your head demanding that you give him the top 3 eyeball grabbing words to put in his sales letter headline (regardless of product), what would they be?
Sex Anus Sex And Your Anus (Just kidding) I like Secrets Revealed and Discover How To and Your Mom Left Her Panties At My House ... Again (Just kidding ... again!)
Consider... Palatial and/or regalia... Maybe also try... HD .. Also.. Video... Also... New... Maybe even... LOLOLOL I like that one.
How about.... "Don't Read This" I haven't tried it myself, but you can bet your life most people will just out of curiosity. That said I have to agree with Ace Lasher "sex" in any combination is probably tops and possibly "Get Yours Free" and "XXX product recall" is a good one but you have to be careful what you are promoting using this or they may pull the plug. ............There's another "XXX Rated" er... Hosiery,blow-up dolls,Films,Shows, etc. Hope this gives you some inspiration.
What about "Don't look behind!" or "Be my friend" or "I love you" or "Feck off loser!" - on second thoughts, that may induce the lunatic to shoot...
