i have a look in some domain names i have why all the time get more and quicker yahoo backlinks and Google harder or no backlinks ??
because google is a mean machine. it doesnt count all backlinks if they are worthless, meaning with a low PR, on the other hand Yahoo counts all of it regardless of PR
Google does take into account all your backlinks that it finds, they only show a snapshot of them. Google may not display all the backlinks, but surely they take in consideration any links you have gained in previous months. So keep going with your linkbuilding activities.
is not true yahoo is showing all links founded. google show only some of them every update there is siteage update every few hours/days pagerank update every 2-3 months and link: update every 2-3 monhts so dont worry if in google link:yourdomain.com show 0 and you collect 1000000 links, wait for update and you will see some of them
Google usually shows up only those pages that are relatively unique and static. Yahoo just needs a URL to add to it's database and is happy to display all the URLs that it gets at any point (including redirect URLs!)
