Yes its look like very simple method and easy. But for noob (like me) it isnt easy to drive people visiting my product list so they will ask a question and so on bla bla bla....I think they still work great. Always remember that there are sometimes peaks and sometimes valleys. Meaning that some methods start to not work as well for whatever reason which causes most people to move on but there is almost always a new day that gives the method new life. That's my experience anyway.
Then would you tell me how to do it?
Thanks
