Can somebody please explain online business to me?

This may seem a strange remark coming from me, being an admin of both kooiii and Socialtisers. However this applied to me about a year ago. I remember how frustrated I was sometimes.
I started my Internet home biz adventure by reading a lot. And had to take hurdless while doing it. Reading lines like "improve your ROI"??? What the heck was that? OK Return On Investment. ??Still puzzled...
So I had to look up what ROI is all about. There were many more abbreviations I did not know and had to look up.
This is something that happens in other areas as well very often. I.e. many doctors write articles with words that only other doctors understand, even if they write it for a general public.
This is because these word are so common for them that they do not realize that many terms are unknown for others.
So, what can you do about it? Educate yourself and if you can't find the answer: ASK!
In learning about marketing and seo Kooiii was a big help to me. There are a lot of articles posted on this subject that are not too technical and easy to understand even if your native language is not English. Many articles are posted on APSense as well.
When you are thinking of starting paid advertising I suggest Socialtisers from Kooiii. Not only because it is cost-effective compared to Google Ads but also the easy to use admin panel to set up your ads and the excellent help desk.
