When using SellerSprite's keyword trend comparison, you might notice that some keywords show different trend patterns compared to Google Trends.
(*Note: We’re referring to Google Web Search trends here.)
There are several possible reasons:
1. Amazon search = shopping intent, Google search = information intent
The user behavior on Amazon and Google can differ significantly. SellerSprite’s keyword trends reflect product searches made by buyers within Amazon, where searches indicate real purchase intent. Google Trends, however, reflects overall search interest on the web, including users looking to learn about a topic—not necessarily to buy.
For example:
When 'iPad Pro' was first released, many users searched it on Google to compare it with regular iPads—but those users may not have been ready to buy, which means they wouldn’t be searching on Amazon.
2. The metrics are calculated differently
- SellerSprite shows actual search volume trends on Amazon over time.
- Google Trends shows relative interest over time (called Interest Over Time), not exact volume.
The Google Trends score is scaled from 0 to 100 and reflects the keyword’s popularity relative to all searches within a specific region and time range—not its absolute volume.
Here’s how Google calculates it:
- It divides each data point by the total number of searches in the selected region and timeframe.
- Then it normalizes the result to a scale of 0–100, where 100 is the peak popularity.
So even if a keyword’s raw search volume increases, its Google trend score might stay the same if the overall search volume on the platform also grows.
Example:
When 'iPhone 16' launched, early searches might give it a score of 50. Later, if searches increased but so did total web searches, the trend score might still be 50—even though the raw volume has grown.
