I mean, are they happy if I use my blog for making money etc. I just want to be sure so that they don't delete my blog. Is it good idea to use blogger/wordpress blog for promoting my products. Or do you think I should buy own domain and hosting? What has been your experience?
I think a lot of people are doing it now but have done better when they have their own domain. If you are just starting with your business then I think it would do, but in the long run you would need to have your own domain to better control the whole thing.
why not, its ok dude, you can use your blogger and wordpress to sell your product or just affiliate product
