before he/she invests one dollar?
Well, my reference is towards available free resources, not about $1 or $1000 and I think I have already made it pretty clear.
To count million dollars one has to start from $1
then his/her time must be very cheap
So, you are trying to tell SEO course is like repair manual?
You buy, read, fix & it starts running? (even this requires time to fix and research if something goes wrong)
Its all about promotion and it requires
research, strategy, analysis, implementation & revision and then continue/redo.
Its a never ending process (unless there is no competitor).
I bet no matter what great course one join, they still end up at a forum, reading free articles and other free sources.
