For some keywords, Google's official API does not yield results. This can be for different reasons:
- Low Search Volume: The keyword may have minimal or no search activity in the specified location and language.
- Insufficient Data: Google's API might not have enough information available for that particular keyword, especially if it's relatively new or less commonly searched.
- Sensitive Topic: Google may choose not to disclose search volumes for terms related to sensitive subjects such as YMYL (Your Money Your Life) topics.
It's important to consider these factors when interpreting the search volume result. Remember to explore the Potential Views metric. This metric can give you an indication for any keyword, also for those where Google isn't disclosing search volumes.
