Google Adwords is the most popular method for traffic. Since they are the top search engine right now it make sense to advertise there if you can afford it. You bid on keywords to get your site at the top of the search when your keyword comes up. There is more involved but it's all laid out at Google. There are a lot of other sites that use this advertising strategy called pay per click or PPC.
The traffic we offer comes from visitors that visit websites that are no longer active. These websites are then presented with other links to visit, related to the website they visited. Your website can be one of those, and best of all if you buy traffic from us, you only pay once they click (when they show interest). It's important to choose the best site to buy targeted traffic - as this is the only way you will get results.
Search engines crawl the Internet to find Web content and return it to update their massive databases. Savvy online marketers can craft their website content by tracking the most popular Internet search terms related to your business (with tools such as Google or Bing webmaster tools or Google Analytics), and ensuring their website contains those terms. Remember, it takes a few months for SEO to start kicking in, so the sooner you start, the sooner you’ll see results.
Great content. Although I disagree with ‘the best times to post’ section. It is important to understand your audience. For example, if your brand/business is in high school, there will be low engagement until 2-5 when they are out of school. I highly suggest using instagram analytics (a subsidiary of facebook analytics) which gives you all of the details on when your followers are active. https://www.facebook.com/help/788388387972460
A good example of a basic but highly functional website would probably be Majestecsocal.com. However, the exact type of design you should be considering depends on your target audience and niche. In some niches (like the one the example website is based around), users would want to have everything in one place, and hence a basic but very functional design would hit the spot pretty well.
I find it interesting that you talked about nutrition supplements for athletes. I am very close to launching such a product for enhancing aerobic exercise performance in women (ie. improved times in a 3 mile run).. The product contains no stimulants or exotic herbs. In fact three of the five ingredients are well known minerals, but in forms not found in most multi-vitamin-mineral supplements. The research behind the product comes from me. The credibility behind the research is that I am a professor of human nutrition with over 100 research papers. Now, the trick will be to use my connections and credibility in a business savvy way.
