Now-a-days it is obvious that Social Bookmarking has reached the peak of popularity. It is because Social Bookmarking is one of the most effective methods of web site promotion. The major search engines all calculate the amount and quality of back links to a site as one of the major scoring features for providing a great ranking. In other words, the more good quality back links your site has the higher in the SERPS you will feature.
By posting a lot of social bookmarks complete with descriptions and relevant anchor text, not only will you gain traffic from the social bookmarking sites themselves (especially if you are lucky enough to hit the front page) but you will also get some good social bookmarking service benefits.
1. Firstly, targeted traffic will increase. Your bookmarks have tags and are also categorized according to their content. That means that the search engines will rank them highly and you will get targeted visitors.
2. Super Fast Search Engine Indexing. This is great for new sites since the social bookmarking sites get spidered regularly meaning that your site will get indexed almost straight away.
3. You will get higher search engine rankings in a shorter time frame. As discussed earlier, the back links generated by social bookmarking score very highly for quality and relevance with the major search engines and can really help propel your site up the rankings in super fast time
4. Your website page rank will increase subsequently. This is very important because it enables you to link your higher PR sites to other lower PR sites that you own, thus boosting the lower ones. High PR is also very valuable when you come to sell links, banners or even your entire site at a later date.
