Best Alternative to Scraping Google Trends
In this guide, we are going to see how to scrape Google Trends with Python. It’s not hard at all, but to do it at scale, you’ll probably need a better solution. I suggest you try Bright Data’s Google Trends Scraper, which is a part of its SERP API product.
It allows you to get structured data easily with an API call, providing you with all the data points you need. Response time and location accuracy are awesome, making it a worthy solution. It’s important to say that I am NOT affiliated with Bright Data, I just had a good experience using its products.
How to Scrape Data from Google Trends
Google Trends has no official API to scrape its data, but some workarounds exist. One popular tool is pytrends, a Python library that makes it easy to download reports from Google Trends. Pytrends is simple and user-friendly, but it has limitations. It can’t always access data behind dynamic or interactive elements.
You can use Selenium with Beautiful Soup to scrape these types of pages. Selenium is a powerful tool that can interact with web pages, even those that use JavaScript to load content. After scraping the data with Selenium, you can use Beautiful Soup to parse the HTML and extract specific information quickly. This combination helps you get the most detailed Google Trends data.
Now, let’s dive into the step-by-step process.
Step 1: Install Python Libraries
The first step is to install the necessary libraries. We’ll use pytrends, a popular Python library for accessing Google Trends data.
To install pytrends, use the following command:
pip install pytrends
Apart from pytrends, we will also use pandas for handling data and matplotlib for visualizing it. You can install them using:
pip install pandas matplotlib
Step 2: Import Libraries
Now, we will start by importing the libraries we just installed:
from pytrends.request import TrendReq
import pandas as pd
import matplotlib.pyplot as plt
Step 3: Set Up the Pytrends Connection
The pytrends library uses a class called TrendReq to interact with Google Trends. We need to create an instance of this class to initiate the connection:
# Initialize a Google Trends session
pytrends = TrendReq(hl='en-US', tz=360)
Here:
- hl=’en-US’ sets the language to English (US).
- tz=360 specifies the time zone. The value 360 represents UTC+6, but you can adjust it according to your needs.
Step 4: Building a Search Query
We need to define the keywords that we want to research. Let’s say we want to search for the popularity of “Python Programming,” “Data Science,” and “Machine Learning” over time:
# Define search terms
keywords = ["Python Programming", "Data Science", "Machine Learning"]
# Build payload
pytrends.build_payload(kw_list=keywords, timeframe='today 12-m', geo='US')
kw_list: This is a list of the search terms we are interested in.
timeframe: This defines the period for which you want the data. ‘today 12-m’ gets data from the past 12 months.
geo=’US’: This restricts the search to the United States. You can change this to ‘all’ for global data.
Step 5: Extracting Interest Over Time
One of the most commonly used features of Google Trends is tracking interest over time. Let’s extract this data:
# Fetch interest over time
interest_over_time_df = pytrends.interest_over_time()
# Display the data
print(interest_over_time_df.head())
This will print a DataFrame showing interest in the specified search terms over time. The output will include the keyword trends and an isPartial column indicating whether the data is complete or estimated.
Step 6: Visualizing Data
Data visualization helps us understand trends more clearly. Let’s plot a graph to visualize the search trends over time:
# Plotting the interest over time
interest_over_time_df.plot(figsize=(10, 6))
plt.title('Google Trends Over Time')
plt.xlabel('Date')
plt.ylabel('Interest Level')
plt.grid()
plt.show()
The plot will show the popularity of each search term over time, making it easy to see trends.
Step 7: Exploring Related Queries
Related queries show other terms people have searched for in conjunction with your keyword. To access related queries:
related_queries = pytrends.related_queries()
# Display related queries for each term
for key, value in related_queries.items():
print(f"Related queries for {key}:")
print(value['top'])
The above code will print related search queries for each keyword you provided, which helps explore how people search for similar topics.
Step 8: Interest by Region
To understand where a topic is most popular, you can look at the geographical interest:
# Fetch interest by region
interest_by_region_df = pytrends.interest_by_region(resolution='COUNTRY')
# Display interest by region
print(interest_by_region_df.head())
The data will show you the interest levels from various countries. For more localized data, use ‘CITY’ instead of ‘COUNTRY.’
Step 9: Visualizing Interest by Region
A heat map is an effective way to visualize interest by region:
# Plotting a bar chart for top countries
interest_by_region_df.sort_values(by='Python Programming', ascending=False).head(10).plot(kind='bar', figsize=(10, 6))
plt.title('Top 10 Countries Interested in Python Programming')
plt.xlabel('Country')
plt.ylabel('Interest Level')
plt.grid()
plt.show()
This will give you a visual representation of which countries are most interested in the keyword “Python Programming.”
Step 10: Google Trends Categories and Data Export
Google Trends categorizes data into various sectors like sports, health, business, etc. You can specify a category to filter results:
# Building payload with a category filter (e.g., 'Computer & Electronics')
pytrends.build_payload(kw_list=["Python"], cat=5, timeframe='today 3-m', geo='US')
# Extracting and exporting data to a CSV file
interest_over_time = pytrends.interest_over_time()
interest_over_time.to_csv('google_trends_data.csv')
This code will get trends data in the Computer & Electronics category and save it as a CSV file, allowing you to perform further analysis or share the data.
Step 11: Handling Data with Pandas
Once you have the data, Pandas makes it easy to manipulate it. For example, you can calculate the average interest over the entire period:
# Calculate average interest for each keyword
average_interest = interest_over_time_df.mean()
print(average_interest)
Step 12: Checking Trending Searches
Google Trends also has a feature called “Trending Searches,” which shows what’s currently popular. You can scrape this information as follows:
# Get today's trending searches in the US
trending_searches_df = pytrends.trending_searches(pn='united_states')
# Display trending searches
print(trending_searches_df)
The trending_searches function gives you a quick overview of what people are currently searching for, which helps stay ahead of breaking news or viral trends.
Step 13: Real-Time Interest
Another cool feature of Google Trends is “real-time trends.” You can check what’s trending in specific regions at the moment:
# Get real-time trending searches
real_time_trends = pytrends.realtime_trending_searches(pn='US')
# Display real-time trends
print(real_time_trends.head())
This allows you to identify spikes in interest almost as they happen, which is valuable for creating reactive content.
Step 14: Keyword Suggestions
If you want to expand your keyword research, you can get suggestions for related keywords:
# Get suggestions for related keywords
suggestions = pytrends.suggestions(keyword='Python Programming')
# Display suggestions
print(suggestions)
This feature can help you discover new areas to explore, enhancing your overall analysis.
Step 15: Automate the Scraping Process
The real benefit of scraping Google Trends is the ability to automate the entire process. You can write a script that runs periodically to collect and save data. Below is an example of automating data collection every week:
import schedule
import time
# Define a function to scrape and save Google Trends data
def scrape_google_trends():
pytrends.build_payload(kw_list=["Python Programming"], timeframe='now 7-d')
data = pytrends.interest_over_time()
data.to_csv('weekly_google_trends_data.csv')
# Schedule the job to run every Monday at 8 am
schedule
Step 16: Handling Common Challenges
When scraping data from Google Trends, you may encounter a few common issues:
- Request Limitations: Google Trends limits the number of requests from a single IP. You can solve this issue by adding a delay between requests or using a proxy. Here is a list of recommended residential proxy providers.
from time import sleep
pytrends = TrendReq(hl='en-US', tz=360)
sleep(60) # Pauses for a minute between requests
- Errors with Pytrends: If Google blocks your requests or returns an error, try re-authenticating with a different IP or wait before making subsequent requests.
- Incomplete Data: Sometimes, data may be incomplete, indicated by the isPartial column in the results. You can handle this by filtering out rows where isPartial is True.
Conclusion
Scraping Google Trends data can provide valuable insights into keyword popularity, consumer behavior, and market trends. By automating this process with Python and using pytrends, you can quickly gather and analyze search interest data to make informed decisions, whether you’re an SEO specialist, researcher, or marketer.
The steps in this guide covered everything from setting up Python libraries to visualizing data and automating the collection process. You can apply these techniques to gather insightful data for your projects or marketing campaigns.
