I am looking for an online service/website that will generate quality traffic to my site so my sales will increase.
You actually have 2 questions: “How to increase traffic” and “How to increase sales”. The second question is actually more important. Just because you get more visitors doesn’t mean you’ll get more sales. You need to be selling the right thing to the right people at the right time. That means your site should clearly identify who your audience is, what problem you solve of theirs, and how you solve it.
Once you’ve crafted this compelling benefit statement, only then it makes sense to find sites that drive traffic to you. And what type of traffic? You only want to attract that matches your audience. If you’re selling a product for men, and you only get women visiting your site, while it’s possible some women will buy the product for a man in her life, you would get many more conversions if you started by getting men to visit your site.
