Keyword Planning

Important: All requests to Keyword Planning services for both standard and basic access are rate limited. Fewer requests are allowed per minute when compared to other services.

Our recommendation is to cache or store results, as you do receive the same response over a long time span. For example, if you request a set of existing keywords, the response is not going to change over a period of hours or days. In the case of historical metrics, the statistics refresh monthly.

Keyword Planning is a process for getting keyword metrics and forecasts as well as searching for new keywords to add to campaigns.

Workflow

Here's a common workflow when using Keyword Planning.

1. Create a manageable list of ideas. You can use historical search volume and CPC to reduce the list of keywords to be included in forecasts.
2. Generate forecast metrics for keywords in order to get traffic for keywords in the plan.
3. Create a new campaign with the new keywords.
4. Adjust the keywords and estimation parameters to find a setup which delivers your marketing goals using the keywords and CPC bids which you selected above.
5. Leave the campaign for the duration of the forecast_period. Forecasts are based on your campaign running unmodified for the duration of the forecast period. Changing the campaign, including bids and targeting prior to the forecast period, changes performance since daily and seasonal trends are also considered.
