When you are trying to build a solid business then you must have a targetted audience, even the medium that you are trying to use for your advertising you have to ensure that it aligns with what you would like to be done. Facebook ads are great but you need to set up your ads well and ensure that it has a call to action for you to offer any further technical assistance that you think may be of help to your prospects. That goes with Google ads.
I have been building something and I still feel it is not yet ready for the paid advertising. So I am buying organically and once I have 100 quality prospects then I will now start to upscale with more robust advertising. I would like to start publishing my ebooks and manuals.
