The [Shopping trends reports](https://support.google.com/merchants/answer/13542370)
provide recommendations and insights about your products based on search demand
for topics related to your inventory.

## Topic trends

You can use the topic trends report to understand the popularity of a topic on
Google Search over time, including its predicted value over the next 13 weeks,
and how its popularity compares to other topics of interest to shoppers on
Google Search. These trends might help you make decisions about when to use paid
and organic Google tools to increase the likelihood of a user seeing your
products when they are looking for it, or a similar product, online.

See [About shopping
trends](https://support.google.com/merchants/answer/13542370) for more
information.

For information about top selling products or brands, see the [best sellers
reports](https://developers.google.com/shopping-content/guides/reports/market-insights#identify_best_sellers).

Your account must meet eligibility requirements and you must ensure that your

are available with the Content API for Shopping.

Here's a sample you can use to view topic popularity and trend data. To make the
request, pass the following Merchant Center Query Language statement to the
[`reports.search`](https://developers.google.com/shopping-content/reference/rest/v2.1/reports/search) method:

    SELECT
      topic_trends.customer_country_code,
      topic_trends.topic,
      topic_trends.date,
      topic_trends.search_interest,
      topic_trends.last7_days_search_interest,
      topic_trends.last30_days_search_interest,
      topic_trends.last90_days_search_interest,
      topic_trends.last120_days_search_interest,
      topic_trends.next7_days_search_interest
    FROM TopicTrendsView
    WHERE topic_trends.customer_country_code = 'US'
      AND topic_trends.date BETWEEN '2023-07-01' AND '2023-07-03'
    ORDER BY topic_trends.date DESC
