The last 3 columns on your right in panel are:
Cost U$ (never mind)
Conversion rate 0,48%
Cost /Conversion U$6,63
What does those mean exactly?
Does that mean I spend U$6,63 for every conversion? (no matter how much I get for that conversion?)
And I convert almost 1 time every some 200 clics? (almost a 0,5%)
(Consider I'm translating so perhaps columns have other works in original english, but I'm referring to last 3 columns on right)
What does those mean exactly?
Silverbytes, here is some info from the AdWords Help Center:
Conversion Rate: [adwords.google.com...]
The number of conversions divided by the number of ad clicks. Note that the conversion rate should not be greater than 100%. Conversions are only counted on Google and some of our Google Network partners. The conversion rate is adjusted to reflect only the ad clicks on which we can track conversions.
Cost / Conversion: [adwords.google.com...]
The total cost divided by the total number of conversions. This statistic gives you the amount spent per conversion. Conversions are counted only on Google and some of our Google Network partners. The cost-per-conversion is adjusted to reflect only the cost of ad clicks on which we can track conversions.
