A major factor of any internet advertising is not to feature any false information that can mislead your customers into parting with money on dishonest pretences.
The Federal Trade Commission (FTC) is there to ensure this does not happen and it prohibits any unfair treatment with reference to the sale of any products through your company.
You also need to bear in mind that if refunds have been promised to customers then you cannot go back on the promise. If this is reported to the FTC then you can expect them to be in contact. Be honest from the start and build up a trustworthy reputation.
One downside with using internet advertising only is when a business is just starting up, there are not going to be many customers that will find your site immediately unless they are looking for a specific product.
With some local newspapers, if the business is something unique to your town/village then it may be featured in the business section and this will most certainly provide some feedback from the local community.
Always ask when you are ready to commence trading because whilst it will cost an initial outlay, the benefits overall could be endless.
Getting the local press to help promote your business will overall help greatly so speak to your local paper as soon as possible and see if they would be willing to assist you with obtaining new customers and building a reputable client base.
Take your time and remember the best businesses are worth the wait if you can make top dollar in the long run.
Always have a list of questions ready when searching for the best advertising for you because overall making a wrong decision could result in a lot of lost income. Choose wisely and take your time.
