For Yahoo to notice that I have 251 inlinks, but Google to say I have 0? Does this make sense to any of you?
Yes. Google doesn't show most links, you have to look in webmaster tools to see what links google has counted.
First of all, I hate threads started in the way you did... That's just gay! To answer your question. duh.
This is normal as yahoo will show many links that google does not. You will always have more backlinks showing from yahoo than you will from google.
Google do not show all your backlinks if you do only search "link:www.yourdomain.com",you can check your backlinks with webmaster tool
use this to find out the true number of backlinks which google sees. http://www.google.com/webmasters/tools/
I think its normal, google show less back links. I have 10000+ links in yahoo, but only 4000 in google. Also, how are you checking links in google? via link operator or webmaster tools.?
It happen to my site also, I think Google has their own rule. My site backlink on AltaVista and AllTheweb is growing everyday but decrease on Google.
It is easily explainable: they are different search engines, so of course they will see things in different ways.
