What is the easiest way in online marketing?

That’s much too vague a question to attract any kind of useful reply. I suggest you read the sticking threads at the top of this forum, then look around and read some of the other threads which interest you. You might also find useful information in the eCommerce forum, if that’s what you mean by online marketing.

After that, if you have a specific question to which you’ve been unable to find an answer, then by all means post again. Meanwhile, I’m closing this thread.
