Google did some update?

[sezampicika]

I have a tehnology based website... Not too much visitors :-)

Most of our visitors come from Yahoo! search, and in last few days we have 300% more visitors from Google.

Site is founded 1 year ago... and we were reciving only few Google hits daily...

But it seems thigs are getting better... Should I be optimistic and expect more or?

Thank you and regards!
