I would honestly check Yahoo Site Explorer – Google doesn’t always show you the backlinks it is aware of.
If you are concerned the page is not indexed, then just simply do a check for the page in Google’s index using the site command – site:http://www.domain.com/page-name.html
The page will still pass Link Equity even if it is new. We really look at the number of clicks it takes to get from the home page to the page as one of the factors in valuing a link. if it is 3 or less clicks, it will pass a good amount of equity .. the further away it appears to diminish.
If the page is not indexed, then you can always stimulate a crawl to the page from another site by linking to it from a page that is crawled daily – I would use a different site than the one linking to it and remove the link once it has been indexed. More than likely you will find this may not be necessary, because of the authority of the linking domain and will simply occur naturally … which is the best way
