I'm wondering if anyone has info about link ageing? Does it exist? I've read in other places that Google waits before giving full credit for backlinks. I have new websites for which I've added a number of PR3, 4 and 6 backlinks but they haven't moved up in Google searches in the 3 weeks since the links were added. Do I need more links or do I just need to wait?
That's right. My suggestion is don't stop your work, but don't get too much links, because you could be penalized.And get the links naturally.
It is not uncommon that it will take between one and three months before you see the effect of the links Just keep on getting good quality links and you will see results soon
Link aging is one of my favorite SEO topics. There are 2 factors to showing up in Google's serps. One has to do with the the amount of time your new site has been indexed in Google. The other has to do with the length of time since google found a particular backlink. I believe that Google does restrict the weight of a link but releases more of it's weight incrementally with time. If you have a brand new domain, it is actually indexed into google pretty fast. I found that if you weight 3 months after new domain name has been indexed before doing any link building, you will get top rankings after you begin link building in another 2 or 3 months. I know some people get sandboxed for a over a year, but that method is consistently working for me.
