Amazon PPC advertising is paid by the advertiser only when their amazon advert is clicked on so you will only be paying for active clicks. It is up to you how much you would like to spend on an advertising budget. We can help advise on the cost depending on your budget and the type of products you want to push forward. MintTwist will fully optimise your ads throughout the campaign duration to ensure you get the most return on your investment possible. Costs per click can also vary depend on the completeness of the targeted keywords.
