Link juice is basically referring to the quality of the websites linking back to your website. The main idea behind having a high quality link juice is to only use highly popular websites which rank well with search engines. There are numerous search engine optimization services which can be used to create quality link juice. Professional SEO services experts and companies which specialize in optimizing online companies, usually create service cocktails which requires them combine various services such as social bookmarking, article marketing and so on, in order to provide their customers with fully tailored solutions that are able to help them reach their targets. Even when taken on its own, the social bookmarking service can provide terrific results, and is also widely seen as the most cost effective SEO services available today. The way social bookmarks and social bookmarking services are directly related to getting quality link juice is through only using quality websites. There are currently literally thousands of social bookmarking websites, but using all of them can prove to be far less effective than using fifty or one hundred of the most famous websites including Digg, Facebook, and so on. Also, search engines can frown upon companies which develop thousands of low quality links in a very short time, so, in this case, it is better to opt for quality instead of quantity as it proves to be much more profitable.
