Limitations:

Google’s focus on paid advertising means that some SEO-specific metrics (e.g., organic competition) are not as detailed as in dedicated SEO tools.

Despite these limitations, Google Keyword Planner remains a fundamental tool for keyword research, particularly for those targeting Google’s search engine and considering Google Ads campaigns.
