The Keyword Historical Trends API provides full access to monthly historical search volume data up to the present date for any keyword. When a keyword is submitted as a parameter, the API returns a chronological list with the number of searches performed in each month and year, allowing users to visualize patterns, trends, and fluctuations in interest over time.
This API is ideal for users who need to understand the evolution of a specific keyword over time. Thanks to its monthly granularity, users can detect seasonality, evaluate the growth or decline of interest in a term, and inform strategic decisions about content, product, or advertising investment.

The Historical Keyword endpoint returns monthly historical search volume data for a specified keyword. This includes the number of searches performed for that keyword, organized chronologically by month and year.
The response data typically includes fields such as "keyword," "year," "month," and "search_volume," which indicate the keyword queried, the specific year and month, and the corresponding search volume for that period.
The response data is structured as a chronological list, with each entry representing a month and year. Each entry contains the keyword, the year, the month, and the search volume, allowing for easy trend analysis.
The endpoint provides information on historical search volumes for any keyword, enabling users to analyze trends, seasonality, and fluctuations in interest over time, which is crucial for SEO and content planning.
Users can customize their requests by specifying the keyword parameter when calling the Historical Keyword endpoint. This allows them to retrieve data for any keyword of interest.
Typical use cases include SEO optimization, content strategy development, market trend analysis, and advertising investment decisions, as users can identify keyword performance over time and adjust strategies accordingly.
Data accuracy is maintained through rigorous data collection methods and regular quality checks, ensuring that the search volume trends reflect genuine user interest and behavior over time.
If the API returns partial or empty results, users should verify the keyword's spelling or try different variations. Additionally, consider that low search volumes may indicate limited interest or niche topics.
