Minimum bid improvement

[smallcompany]

I wonder if anyone was able to watch how minimum bid improvement influenced the cost per click.

If you optimized your ad text, and landing page, and had your minimum bid (with great QS) went from $0.06 to $0.03 for a particular keyword, did you see an average cost per click going down?

This would be to help people figure if it is worth of improving the score that is already great with minimum bid in range of 5 or 6 cents.

Thanks

It's too volatile - bids at that level are likely to jump around too much. I had bids with great quality scores jump around from minimum bid 3 cents to minimum bid 5 cents sometimes six to ten times a *day*. Times 1000 keywords. If you're trying to play in that field, you're going to spend a *lot* of time chasing stray pennies.

Thanks netmeg.

To make this query clear, I am not keen to have cost per click to be in that range.

Keywords I am curious about are having fixed and boring 5 or 6 cents applied as minimum bids, and QS says "great". I pay $1.75 per click.

Now, QS "great" is the best you can get in that field, right? The only remaining indicator is the minimum bid that could be improved until it gets to 1 cent.

So, if we bring minimum bid from 6 to 3 cents, would that, and how, reflect onto our $1.75? Should we expect to pay less, $1.55 for example?

If not, why bother, right?

It would be nice if AWA could take a sec and give us interpretation of this in her/his own words.
