Over the Xmas period. I bought two links. Both were the same price. One was a sponsored link - picked up as a backlink on Yahoo Site Explorer within 4 days. Very pleasing. The other was a link within a directory of a very well established and high ranking site in Google in my country - I was expecting it to be picked up by Yahoo Site Explorer within a week. Still nothing. When I type in the business name it comes up in 3rd place within this directory. So it has definitely been indexed. But why is the link in the this directory not coming up on YSE?
it might not show as backlinks..but it doesn't mean that its not considered.. its up for google show a link as backlinks or not.. and btw... buying and selling links is against google guidelines..
May be not consider as a backlinks , but we doesn't intend that it's not considered.. it all depends on the google show link as backlink or not...
You shouldn't buy links, it's safer just to build them manually, it does take some time but it's worth it in a long run.
Google is very sensitive on buying and selling links, especially if they see it is made for manipulation of PR and rankings. Otherwise, Google don't usually show entire backlinks they've recorded for a site, just a portion on it are shown on link:site.com tool.
I guess if the backlink is not related to your niche, google doesn't show the backlink ie the link you bought...
