I give you 3 services for 1 price; traffic and SEO work and content writing. What you need to start off is quality traffic and to advertise to people interested in your app. This is what I have been doing for 15+ years.
The traffic I send you is 100% adsense safe, 100% real people and will not penalize your website.
There is a low bounce rate. I also advertise for you via adwords. I do this from my adwords account and pay for this myself as it is easier for me to control the campaigns for different clients this way.
Traffic you receive will come from adwords, social media networks, organic traffic, amazon traffic and direct traffic.
The benefit of using this service is it improves Alexa and SEO rankings, and traffic begins arriving within 3-7 days. Estimations would be 50+ visits every day – although almost always higher (if someone claims they can send thousands every day than they are using methods that will eventually get your website penalized).
The SEO work basically consist of backlinks. This improves your SEO and Alexa rankings, and improves traffic in the long run.
The benefits of this are improving your SEO and Alexa ranking, as well to drive traffic.
Content Writing; An original article for your own blog or website OR Instead of posting this article on your blog I can place the article into Google News, also on many directory submissions, etc...
If you do not have a website, i would replace SEO and the articles with excellent facebook marketing!
