This blog is about getting started on line .... and being careful there!What should you be "selling" on line? That's entirely your choice - providing a service, info products ,matrix programmes , dropshipping , selling memberships  etc etc .
But unless you are concerned about PERSONAL BRANDING and getting yourself found among the millions of websites  on line , please pick a book here and go home read them/it for a bit of self evaluation or watch some more movies or snooze away just right beside the fireplace.
To be spotted on line by the Empire Scout , Google ,  you need a domain name and hosting. Right after that you 'll have to trudge the old silk route- getting site visitors - and that leads us to marketing  or traffic.There are several ways to bring traffic to your site , but about the best is instant traffic.
Unless you look into the above , your online prescence will never be known.
