I would like to just confirm this is the way the new planning limits work.
I use the following process to get volume data for 800 keywords
1. I create a keyword plan. This counts as 1 operation.
2. I create a keyword plan campaign. This counts as 1 operation.
3. I create a keyword plan adgroup. This counts as 1 operation.
4. I add the 800 keywords to the keyword plan. This counts as 800 operations.
5. I generate the historical metrics. This counts as 1 operation.
6. I remove the keyword plan. This counts as 1 operation.
So to get the data for 800 keywords, it will cost me 805 operations.
Therefore, I want to confirm that with the basic plan we are limited to 15000 operations per day and this means that we can get maximum of only 15000 keywords in a single day.
