Getting your website into the top ten results of Google for competitive, high search volume terms that directly relate to your business can be quite challenging. These types of search terms are highly desirable because they are what your potential customers type in when they're ready to buy what you offer. Of course, your competitors are aware of this too, and that's why there is so much competition. Getting onto the second and third pages of Google can be relatively simple, but getting that extra push to be on the first page is not. However, link wheels can give you the boost you need.
Creating link wheels is very time consuming, as it involves building Web 2.0 properties and placing useful articles on them. You then have to properly link the properties to one another in a special fashion so they're all increasing the value of the other properties. After doing this, they'll have a lot of link juice which can then be passed to your main website. This powerful technique is used by the big companies because it gives them the edge they need to remain ahead of their competitors on the first page. With that said, they are not the ideal strategy when you are first starting out.
You shouldn't go through a link wheel service if your site is not ranked at least on the second page of Google for competitive terms. They are not very effective when your site doesn't have much authority or visibility, as the powerful boost a link wheel gives the site might look suspicious to Google. However, when you are ranking in Google's top 20, the boost from a link wheel is acceptable and even expected, so it will shoot you onto the first page without any risk of getting your site penalized.
You will find that hiring a link wheel service to handle the creation of link wheels is the most cost effective way to go. The best ones have writers that will create the content for the Web 2.0 properties, and they'll even make a short YouTube video for you. They are experts at properly linking the Web 2.0 properties, and will be able to give your site a dramatic boost to put it on the first page of even very competitive terms.
