YSE shows many backlins but google shows only 1

Hi guys,

On Yahoo, i get some ~300+ backlinks,
MagesticSEO also shows over 90 backlink domains and ~300+ backlinks.

But when I do: link:xxx.com I get only 1 return...

Something wrong?

(and my backlinks shown on other sourced are indexed on google)

Don't concern yourself with it too much.
None of them fully cover all the possible links. Just keep linking and trying to get things indexed. Sometimes it helps to do one thing at a time, if you see a jump one to two weeks after doing something, you'll know it was successful.

Cheers Thanks!
