The Google Trends connector supports between one to five keywords, country and region. Worldwide is the default region but it is also possible to specify in detail, like the United States or Texas.

Google Trends normalizes data to make comparisons between search terms easier. Search results are normalized on time period, region and the relation between each selected keyword. Following this process:

The connector gives you a daily granularity on a month-to-month, week-to-week, year-to-year or custom time range to determine the interest of one or several keywords over time.

If we want to compare the relative popularity of the search terms "bigquery" and "redshift" worldwide, we would connect a new Google Trends source using these options:

This will give you Interest on a daily granularity split by the Keyword and Geo dimensions. Like this:

In this example, where a 'Monthly' query time window is selected, the data is fetched in chunks of months. So, Jan 1 - Jan 31, then Feb 1 - Feb 28, etc.

To compare the data in Funnel to the Google Trends interface, set the date range between the first and the last of the month, and repeat that for each month you want to compare. Note that because Google bases the data on a random sample, numbers might not always match exactly. Read more here.

This Google Trends view can be compared to data in Funnel for December 2020.

The report "Interest by City" is very similar to the "Interest over time" report mentioned above. The main difference is that data is distributed by cities as well. Note that Funnel can't guarantee which cities are provided by Google Trends. A city may be present in the results one day but unavailable on the next day.

The "Related Queries" report adds the possibility to find queries that are related to a specified search term.

The "Related Topics" report adds the possibility to find Topics that are related to a specified search term.

One source per keyword will give you the interest for this keyword whereas all keywords in one source will give you the selected keywords interest relative to each other.

For the two interest reports it is possible to specify a "Query Time Window" as of weekly, monthly, yearly and a custom time window. This makes it possible to choose the time interval that Google Trends should be using when calculating the numbers.
