Google published a video that disclosed five insights about Google Trends that could be helpful for SEO, topic research and debugging issues with search rankings. The video was hosted by Daniel Waisberg, a Search Advocate at Google.
1. What Does Google Trends Offer?
Google Trends is an official tool created by Google that shows a representation of how often people search with certain keyword phrases and how those searches have changed over time. It’s not only helpful for discovering time-based changes in search queries but it also segments queries by geographic popularity which is useful for learning who to focus content for (or even to learn what geographic areas may be best to get links from).
This kind of information is invaluable for debugging why a site may have issues with organic traffic as it can show seasonal and consumer trends.
2. Google Trends Only Uses A Sample Of Data
An important fact about Google Trends that Waisberg shared is that the data that Google Trends reports on is based on a statistically significant but random sample of actual search queries.
He said:
“Google Trends is a tool that provides a random sample of aggregated, anonymized and categorized Google searches.”
This does not mean that the data is less accurate. The phrase statistically significant means that the data is representative of the actual search queries.
The reason Google uses a sample is that they have an enormous amount of data and it’s simply faster to work with samples that are representative of actual trends.
3. Google Cleans Noise In The Trends Data
Daniel Waisberg also said that Google cleans the data to remove noise and data that relates to user privacy.
