NEVER pay for bringing traffic to your website! It will cost you money, it will hurt your SEO rankings, and your traffic numbers will fall down again afterwards.

If you want traffic, try these tips instead:

• Create unique, high quality, interesting or useful posts,that people want to read, and even better, want to share and talk about
• Share the links to your posts on your social media and other profiles (forum, Medium, etc)
• Engage on those social media and other sites and make sure people can easily share your content too, for instance by using addthis.com 
• Repeat
