Honestly this is not likely what you think at all. This is at best a borderline service for anyone to be offering.
Organic means natural growth, as in, for some reason like my Droog Bob tells about your song, I come over, play it, like it and Subscribe so I get told when you have a new song. It happened by itself with little to no “planting of seeds”.
This is not the sort of thing you can really buy unless you paid Bob to talk to me. Creepy.
You can put adverts on busses as I saw with a Fifty Cent album. But that only works if people know who Fiddy is, or like his look enough to search for him.
Most of these (dis)services that claim to bring you traffic simply build bots (or pay poor people a few cents) to visit and/or Like. Nothing is built. Google or YouTube may well see all the odd traffic and de-rank you for spamming.
So if nothing happened, you probably did business with someone who isn’t even any good at spoofing their spam spoof.
Understand I am guessing, but the odds are probably on my side. I have been in the Music Game for 30+ years. Most of what people tell each other in wannabe Muso Forums is a stupid as what people with no sales here tell each other about how to get sales. Total
In selling a new act t an audience you have to work on tiny numbers of people. One at a time even. Millions at once is Billie Eyelash did not get famous overnight from a bedroom recording at all. It is a nice fantasy for office-girls to think it could be them but there were years of work with promoters, managers, and money spent to get that first record made.
Does your song have a Youtube video (not the auto-create from your Aggregator)?
