Google shows url name instead of title

[mobipligg]

Hi pliggers,

i got a tiny problem.

If i search my website by typing sitename without .TLD, like mypliggsite123,
google shows me

mypliggsite123
Social news , videos, pics and more about blabla and so on..
cache - similar sites

But if i search on keyword google shows my real title
like my pligg site 123 - spanish car news social network e.x.

How can i fix this ?
Google should take the title not the sitename without .TLD

Could you give me more specific examples to explain this? Give me a couple actual links that demonstrate it.
