April API rate sheet reductions

[AdWords API Advisor]

We have made some enhancements to our system that have enabled us to
drive greater efficiencies that are now reflected in savings to our
API users.

Effective today, we have lowered the number of API units charged for
the following services:

Service Name, Former Rate (in API units), New Rate

* addAds: 125 -> 50 per item
* addCriteria: 25 -> 20 per item
* updateCriteria: 10 -> 3 per item
* getKeywordVariations: 25 -> 20
* getKeywordsFromSite: 25 -> 20
* estimateAdGroupList: 25 -> 20 per item
* estimateCampaignList: 25 -> 20 per item
* estimateKeywordList: 25 -> 20 per item
* scheduleReportJob: 1000 -> 500

Updated Rate Sheet can be found here:

API units will continue to be charged at a cost of US$0.25 (or local
currency equivalent) per thousand units consumed; but these per-
service rate reductions will bring substantial savings.

And as always, we encourage developers to use list methods whenever
possible (e.g. addCampaignList). They are the most efficient (and cost-
effective) way to process large data sets.
