I am trying to rank an internal page of my site and i am building backlinks as only manually commenting on do follow blogs. I have made about 300 backlinks so far building links every day. Yahoo explorer is showing 120 backlinks. I started building the links a two weeks ago but the page is still not appearing neither in google, yahoo or bing. After how much time i should expect the page to appear in the search result for the keyword i am targeting and is it harder to rank internal page than the home page?
