How to track Google trends in Python using Pytrends

In this tutorial, we will learn how to track Google trends in Python using Pytrends.

Pytrends is the unofficial API for google trends in Python. This is a simple API that allows you to track the different trends going on in the world’s most popular search engine – Google. It logs in into google on your behalf and takes in data at a much higher rate than manually possible. However, this particular API will be functional only for the current Google backend technology. Once that is changed this API shall no longer hold good.

How to install Pytrends

For Python 2 installation :

pip install pytrends

For Python3 installation :

pip3 install pytrends

Connecting to Google

from pytrends.requests import Trendreq

pytrends = TrendReq(hl='en-US', tz = 360)

What are Keywords?

Keywords are important words or phrases that help users find your content online. Whenever you type something in the search box Google looks out for certain terms – keywords – and then shows you all the pages where these keywords are present. Now for us to track Google trends, we need one or more keywords to search for. These could be anything from your favorite movie to academics to sports, politics, etc. And as we all know Google knows everything so it will give us the results very easily.

Search Keywords in Pytrends

Put in all the keywords we want to track in a list in Python. For this example, we are taking ‘Machine Learning’,’Python’ and ‘Linear regression’ all related to the subject in concern.

keyword_list = ['Machine Learning','Python','Linear Regression']
pytrends.build_payload(keyword_list, cat=0, timeframe='today 5-y', geo='', gprop='')

Different Filters over Searches

Interest By Region

# Interest by Region
df = pytrends.interest_by_region(resolution='COUNTRY')
print(df.head(10))
df = df.reset_index()
df.plot(x="geoName", y="Machine Learning", figsize=(120, 10), kind ="bar")

The output of this code :

Trending searches :

To get in touch with all that is going on in today’s world, we use this method of trending searches.

#trending searches
df = pytrends.trending_searches()
print(df.head())

The output of this code :

                        0
0  Coronavirus vaccine news
1                Italy news
2          Maharashtra news
3                      Zoom
4   Covid 19 vaccine update
5          Domestic flights
6                 Covid out
7           Curfew in Delhi
8                     Skype
9                  Vivo V19

Related Queries 

Similarly, you can see the searches related to a particular trend as well. You do this using the related_searches method.

#related topics
pytrends.build_payload(kw_list=["Machine Learning"])
df = pytrends.related_topics()
print(df['Machine Learning']['top'])

The output returns a dictionary, we see only the top searches related to Machine Learning.

Output:

value formatted value  ...                 topic_title            topic_type
0     100            100  ...                    Learning                 Topic

There are various other filters available in this API such as – Related Queries, Top Charts, Suggestions, Historical Hourly Interest, etc.

This was a beginner level tutorial on how to track Google trends in Python using Pytrends. To track particular websites, you would need Scrappy or Beautifulsoup. More on that later.
