I have created a new site which is basically reviewing certain products etc. I made it the day before yesterday and I am just waiting for my articles which will take another 2 - 3 days. Currently I have no posts but have done all the On-Page SEO needed. I submitted my site-map etc. I was wondering if I should begin to build backlinks to the site even though there is no content. I was thinking about doing maybe 5 forum profile backlinks a day or 5 blog comments a day. What do you think?
