How to Get Your Backlinks Indexed in Google
http://bit.ly/1i0DEbM That is the short version. What many people forget about though is if they get a backlink on a specific page within a website and that page is not in Google's index the backlink will not be valid and will therefore not help your rankings. Why? Because if Google doesn't know about that page, it won't know about your backlink within that page.
What we need to do is ensure that all the pages that include a backlink to our website are indexed in Google. There are many ways of doing this. All we need to do is help Google find these pages so that it can crawl and cache them adding our backlinks to their links database.
Many people ask why we need to do this. The answer is simple. Although the search engines have many powerful servers running different tasks on an ongoing basis it still has to process and monitor billions of web pages. If a website adds new pages on a regular basis, even with the use of a sitemap it is easy for some of those pages to get buried which makes it harder for the search engines to find them.
So how do we get these pages indexed. Although the timescale can vary, the concept is quite simple. We use various types of sites such as popular bookmarking sites and forums as the search engine bots will frequent those sites almost constantly. All we do is link to our 'backlink pages'. With bookmarking sites you would simply bookmark the urls and with forums you would temporarily add a link to your forum signature which would instantly populate potentially hundreds of indexed forum threads with the link. Using methods like this you can often get your backlinks indexed in a matte of hours.
