I've added a new webpage and done some blog posts, forum posts and article submissions, now i want to check the backlinks, how can I do this for the new webpage? I've tried the likes of backlink watch (dot) com and it only checks for entire site.
if you are trying to find the backlinks for your inner page, then you can search google or yahoo using the following search string: link:http://yoururl.com/innerpage and you will find the backlinks to that specific page/post. however, it takes a while got google to show the backlinks where yahoo shows them lot sooner
Google webmaster tool is one of the best methods. Download your external links. You might also want to visit the page using seo quake and click on Yahoo Link field (not on yahoo LD - linkdomain).
Google webmaster tools and yahoo site explorer will both show which sites are linking to those pages. Between the two, I think that yahoo site explorer gives better results. I have seen links take 6 - 8 weeks to show up in my google webmaster tools. But with yahoo site explorer, it seems to update faster and will show more links.
