First of all, sorry for my broken English. I just would survey that what kind of promotion or ads you prefer? Promotion banner or ads that Full with long paragraphs such like Start your business now, chance of life time, bla blaa.. Or Straight to main point such like 30% discount, buy one and free one?
I can say that a kind of promotion depends on your marketing purposes and on peculiarities of the product you are offering. there is no universal promotion for nay product, service or marketing.
I prefer viral marketing, but as it was said, you should choose a method suiting you best. (aтв from those you mentioned - I mostly use the second one)
I like things that are simple because most of the time they are blowing smoke up your corn hole anway examples I like live the free life for $15 escape the job travel the world be the boss kick yours in the head
