Real traffic can never be bought. If you want to purchase traffic from somewhere, do it wisely, otherwise you may be caught by Google and be punished severely, for example, the ranking of your website may go through a sharp decrease, or worse, your website may be kick out of the google index.

Better not to purchase traffic, especially the cheap traffic like fiverr--some wesites purchased traffic from there and really got "cruel" punishment.

If you want to attract large traffic, to increase the exposure of your website--market it on facebook, twitter and other social media, write articles about your website and submit those articles to anywhere related, find social bookmark sites to submit your website to them. It may take a little long time, but really effective and safe.
