Does google care how often you change the title and/or the description of your site? I've changed it about 3-4 times over the past few days, because one time I had a typo, and the other times I was just fine tuning it.
It doesn't matter at all. Although it may take a while for Google to reflect the changes in the index.
Google is probably not indexing your pages daily anyhow. So it probably didn't notice. I agree: nothing to worry about. This is just part of the online game: you finetune and change till you are happy with it.
Well, I've changed them many times, once my changes apeared in google and I have ranked higher for my keywords. I was taking notes about the descriptions used and rankings for the same title meta tags, then I choosen the one where i ranked higher. I won about 3-5 positions with title and meta tags tweaking...
google does not look how often do you change your title/desc./keywords . i think it looks only are they relaevant to your page content
