It is important to understand why your audience views your content and to add real value to your audience through your content.  While asking your audience to buy something may be annoying, the fact of the matter is, if you don’t ask you will never get it.  So, in order to not make it annoying, make sure that your value proposition is strong enough to demand money. It is also important to call something as sponsored, if that’s the case, so as not to break the trust of your audience.
