Hello, As Tino points out, the cost in API units is identical regardless of the batch size you use for your addCriteria() calls. So that's not a consideration.
Here are a couple of things to keep in mind when deciding how to batch up your criteria: - You need to either call checkCriteria() in advance to make sure all your criteria are valid, or be prepared to handle the case where one or more of your keywords are considered invalid. If one keyword in your addCriteria() request is invalid then none of the other keywords in your request will be processed (http://code.google.com/apis/ adwords/docs/developer/adwords_api_services.html#policychecking), so that is something to consider if you're not calling checkCriteria() in advance. - If your primary concern is speed and this isn't a one-off type of operation, you may see better performance by bucketing your criteria by ad group, and only passing in criteria that are added to the same ad group in each addCriteria() call. This isn't the more important optimization and will only save you a few milliseconds at best, but it's worth mentioning. - There's some overhead involved in SOAP requests and responses, from the XML de/serialization to the time it takes for a roundtrip HTTP request. You will in general see higher throughput if you can minimize the number of total SOAP requests you make. - Your HTTP client library might be configured with a client-side timeout that will close the connection if the SOAP server takes to long in sending back a response due to a very large request. I'm not aware of any server-side timeouts that we impose--at least nothing that's hardcoded. So take all that into account. As for specific recommendations for batch sizes, you should be fine with passing several hundred criteria into an addCriteria() call. If all you're looking to do is add 10,000 keywords in a one-off operation then I don't really see much benefit in doing them more than a hundred or so at a time in a loop.
