In terms of SEO or also known as Search Engine Optimization, relevancy stands a very important and critical aspect. So in order to address to this lack of relevancy, I found a solution to this and this is social bookmarking, a technique that generally can attribute to the effectiveness in raising the traffic to a site, page or blog. Some social bookmarking sites are also known as networking or community bookmarking sites. Generally, their functions are the same. Basically, what you need to do is to send in the links or the URL of your pages, articles, websites or blogs and it will be marked in that particular site. By doing this, you are expanding the presence of that particular page and increase the chance of it being viewed by visitors who search in that particular bookmarking site. This function because of the increase in the keywords relevancy also increases the PageRank of your blogs, websites, pages or articles.
