As a preliminary investigation, Pearson and Kendall rank correlations are examined to explore the relationship between Google Trends data and COVID-19 data on cases and deaths. To that end, in this paper, the role of Google query data in the predictability of COVID-19 in the United States at both national and state level is presented. In short: the five word limit is no longer yours.During the unprecedented situation that all countries around the globe are facing due to the Coronavirus disease 2019 (COVID-19) pandemic, which has also had severe socioeconomic consequences, it is imperative to explore novel approaches to monitoring and forecasting regional outbreaks as they happen or even before they do so. With this method, you can now answer big questions like: how popular are my products compared to those of my competitors, did a recent ad campaign impact interest in different product categories differently…

To make multiple queries comparable, include a control term that will be the largest in every search.

Google Trends is a good proxy for public interest.

You should note that if you are trying to do this for more than a handful of queries, you will hit Google’s DoS (Denial of Service) limits relatively quickly, so you will want to pause your loop for a few seconds between each query. Below you can find a quick snippet to get you started: import pytrends kw_list = #list of topics I wanted to search trends = dict() for i in kw_list: #build out query pytrends.build_payload(, cat=0,timeframe='today 5-y') #save trend to dictionary trends = pytrends.interest_over_time() Can I do this programmatically?įor the streaming content project, I used the Python library pytrends, an unofficial API for Google Trends. For example, “Bitcoin” has such high search volume that many titles were normalized to zero ( see what I mean here). Using domain knowledge, I knew which titles would see particularly high search volume, so I looked for a word that was safely more popular than our most popular titles, but not so popular that I’d lose any real information on the less popular titles. It’s a bit like a recipe: you want something stable and safely higher than all of the terms you are interested in. We went through the list of both platforms’ best content and pulled each title’s Google Trends measure relative to that of the word “France”.Įxactly how did we decide to use the word “France”? It follows then that if you want to compare more than five topics in Google Trends, you just need to include a control topic in each search.įor example, in a recent project, my team and I wanted to compare the popularity of Netflix’s and Amazon’s content. So long as two queries share the same most popular topic, they will be scaled in the same way, so the trends will be comparable. If they don’t have the same largest topic How can I look at more than five trends at a time? But as we mentioned earlier, all searches are scaled to the highest volume topic in your query, so two different queries aren’t comparable if they don’t have the same largest topic.

The obvious reaction to this limit is, “well, I’ll just use multiple queries”. For example, early in the democratic primary you wouldn’t have been able to easily compare the popularity of all the major candidates. This is obviously limiting if you want to explore any real world question. Five Trend LimitĬurrently, the public-facing Google Trends site will not allow a query with more than five terms. What makes working with Google Trends tricky?Īs handy as Google Trends is for quickly taking the pulse of the internet, the structure of the service itself makes larger scale application difficult for two reasons: 1. In short: Google Trends doesn’t exactly tell you how many searches occurred for your topic, but it does give you a nice proxy. It combines all of these measures into a single measure of popularity, and then it scales the values across your topics, so the largest measure is set to 100. That is to say, for each word in your search Google finds how much search volume in each region and time period your term had relative to all the searches in that region and time period. The resulting numbers are then scaled on a range of 0 to 100 based on a topic’s proportion to all searches on all topics. Otherwise, places with the most search volume would always be ranked highest.

From their FAQs:Įach data point is divided by the total searches of the geography and time range it represents to compare relative popularity. Google Trends gives you a normalized measure of search volume for a given search term over a selected period of time.
