I was just reading one of threads and it was continuing mentioning Solo Ad. can you help me? What is solo ad. ? Where do you use it? Thanks in advance
It is a kind of ad which are basically email newsletters which are sent to mailing list, it is widely considered as spamming, I never suggest anyone to do such kind of promotion.
I been seen here a lot of people talk about it and saying they are getting great result. but you are saying is a spam marketing
