How much data (wasted money) is required before it's safe to start using single keyword ad groups.

Complete Question: I watched the video on single Keyword ads and it was brought to my attention that Google will barely rank ads if its overly optimized on a fresh campaign with no data. How much data (wasted money) is required before its safe to start using single keyword ad groups. Thanks in advance

It's best to start with what Jeff refers to as "tight ad groups." This means to group your keywords closely by subject/intent of the search.

There's no specific "amount" of data you need to accumulate to tighten your ad groups. That should happen naturally over time as you gauge the performance of your keywords and monitor your search term report.
