For website’s optimization on social bookmarking I am having hardships and have attempted numerous techniques for the same. The problem is that I am still not successful because of the unsure nature of the problem. I am not able to thrive in spite of attempting and utilizing link building together with the entire types of techniques in SEO. My PR is totally zero and still I am not seen. I do not have a lot of back links either even though I am conducting activities on link building. I need suggestions and opinions on the same.
