Summary
Microsoft adCenter emerge as the better Search Engine (Paid Search advertising Platform) – from a visit to sale conversion point of view – above Google and Yahoo.
Looking at a site wide non-segmented visit to sale conversion rate is almost meaningless, but used properly, it is a fair metric to use in paid search optimization – In my quest to create a set of segmented Paid Search Benchmarks for this metric, I found that Microsoft appears to be the best converting Search Engine today!
I conducted a study on 15,014,924 visits across multiple global commerce web properties in Q4 2007, with approximately USD 1.2 Million in Paid Search advertising spend (only web properties that actually generated revenue and had SALE actions deployed were included)
The reasoning behind researching Paid Search only and not overall traffic from the individual search engines – Is that we per definition have not only a lot of data noise in organic traffic, but more importantly, that from a conversion point of view, you would be much more likely to compare apples to oranges, as you do not control keywords, creative, landing page etc. (you are most welcome to post further questions about my methodology in the comments)
Average Visit to sale conversion rate from Paid Search
103 - Microsoft
100 - Normalized AVERAGE
088 - Google
076 – Yahoo

The findings which were exceptionally consistent from web property to web property – consistent as in the order of the engines. I did find that there was a large fluctuation, but in almost every instance the order hold true.

Is this then true for everybody? – Not necessarily! This is not a researched conclusion; but a mass Paid Search visit volume observation.
It is of course a lot more provocative visualizing the result as above, but a better representation would probably be to include highs and lows (distribution) and an indication on the deviation.
As a side note; It was actually a quite different set of conversion rates and much more diverse and unique from site to site, when I looked at other success actions. Actions such as user signups, request further information etc. (comparing or presenting the absolute conversion rates, would of course not makes sense).
Conclusion
Comparing visit to sale conversion rate across search engines, should probably include some sort of search engine base line attitude towards Cost Per Action (CPA) – and not just a direct comparison. Furthermore; it is definitely worth investigating other search engines (even using the same keywords, Creative etc.) – if you are on Google AdWords only!
