如何用gtrendsR获取Google Trends国家级别interest_by_country数据

Hey there! Let's break down your two gtrendsR questions with clear examples and explanations:

1. How to View interest_by_country Data #

When you run gtrends(), it returns a list object with several components—one of which is exactly interest_by_country, a data frame containing country-level relative interest scores for your keywords.

Here's how to access and inspect it:

library(gtrendsR)

# Replace with your actual keywords and desired broad geo (e.g., "world" for global data)
trend_results <- gtrends(
  keyword = c("keyword1", "keyword2"),
  geo = "world"
)

# Print the country-level interest data to console
print(trend_results$interest_by_country)

# For a more readable table in RStudio, use View()
View(trend_results$interest_by_country)

Note: interest_by_country only populates when your geo parameter is a broad region (like "world", "EU") that includes multiple countries. If you set geo to a single country (e.g., "TR"), this component will be empty.

2. Getting National-Level Interest Data for Turkey (geo = "TR") #

First, a quick clarification: Google Trends doesn't provide absolute "click numbers"—all values are relative interest scores (0-100, representing the popularity of a keyword relative to the highest point in the selected region and time period).

If you're seeing only city-level data when setting geo = "TR", that's because the interest_by_region component returns sub-national regions (cities/provinces) for a single country. To get national-level data, use one of these approaches:

Option 1: National-level time series trend #

The interest_over_time component of the gtrends() result gives you the overall relative interest for the entire country over time. This is the national-level trend you're looking for:

tr_trend <- gtrends(
  keyword = c("your_keyword1", "your_keyword2"),
  geo = "TR"
)

# Inspect the national-level time series data
head(tr_trend$interest_over_time)

Option 2: Turkey's national score compared to other countries #

If you want to see Turkey's national interest score alongside other countries, set geo = "world" and filter the interest_by_country data:

tr_world_trend <- gtrends(
  keyword = "your_keyword",
  geo = "world"
)

# Filter to get only Turkey's national data
turkey_national_data <- subset(
  tr_world_trend$interest_by_country,
  location == "Turkey"
)

print(turkey_national_data)
