In our data-centric age, information is currency and web scraping stands as a formidable means of acquiring valuable data from the web. This blog post is your ticket to understanding the intricacies of web scraping, with a specific focus on extracting insights from Google. We’ll explore how to scrape Google related searches, and Google autocomplete suggestions data using the Python programming language. It’s important to be aware that web scraping Google search results may raise ethical and legal considerations, potentially conflicting with Google’s terms of service. Therefore, this tutorial is offered solely for educational purposes, equipping you with knowledge about web scraping techniques and their ethical implications.
Prerequisites: Before we dive into the world of web scraping, you’ll need a few tools and prerequisites:
- A working Python environment (Python 3 recommended)
- Required Python libraries: requests, BeautifulSoup, pandas
- An active internet connection
Setting Up the Environment: Setting up your Python environment is the first step in this journey. Follow these simple steps:
- Install Python (if not already installed).
- Create a virtual environment (recommended).
- Install the required libraries using pip.
# Example: Creating a virtual environment
# Open your command prompt or terminal and run the following commands:
# Create a virtual environment named 'web_scraping_env'
python -m venv web_scraping_env
# Activate the virtual environment
# On Windows
web_scraping_env\Scripts\activate
# On macOS and Linux
source web_scraping_env/bin/activate
# Install the required libraries using pip
pip install requests beautifulsoup4 pandas
Understanding the Code: Let’s start by breaking down the Python code that powers our web scraping adventure. We’ll walk you through the purpose of each function and its role in the code.
# Example: Function to retrieve data from Google suggest
def suggest(key):
r = requests.get(f'http://suggestqueries.google.com/complete/search?output=toolbar&hl=en&gl=in&q={key}')
soup = BeautifulSoup(r.content, 'lxml') # Use 'lxml' parser
sugg = [sugg['data'] for sugg in soup.find_all('suggestion')]
return sugg
Retrieving Data from Google: In this section, I’ll explain how the code sends an HTTP GET request to Google’s search page for a specified keyword. You’ll also learn how BeautifulSoup is used to parse the HTML content of the search results page.
# Example: Sending an HTTP GET request to Google
response = requests.get(search_url)
# Parsing HTML content with BeautifulSoup
soup = BeautifulSoup(response.text, 'lxml')
Extracting Related Searches: The “Related Searches” section of Google can provide valuable insights. We’ll guide you through the code that extracts these related searches, providing code snippets and explanations for each step.
# Example: Extracting "Related Searches" using BeautifulSoup
busquedasRelacionadas = soup.select('.Q71vJc')
if busquedasRelacionadas:
related_searches = [search.text.strip().lower() for search in busquedasRelacionadas]
Extracting Google Autocomplete Suggesttion: Discover how the code retrieves Google Autocomplete Suggestion data, uncovering its usefulness and applications. I’ll include examples of “Google Suggest” data to illustrate its potential.
# Example: Extracting "Google Suggest" data
google_suggest = suggest(keyword)
Exporting Data to Excel: Pandas, a powerful Python library, helps us create and manipulate DataFrames. Find out how the data is structured within the DataFrame and learn how the code exports this data to an Excel file.
# Example: Exporting data to an Excel file with pandas
df.to_excel('google_data_india.xlsx', index=False)
Generating Additional Data: To enhance your web scraping skills, we’ll explain how the code generates additional “Related Searches” and “Google Suggest” data for each suggestion. We’ll emphasize the importance of adding a delay to avoid IP blocking.
# Example: Generating additional related searches and Google suggest for each suggestion
for suggestion in google_suggest:
print(f"\nGenerating related searches and suggest for: {suggestion}")
time.sleep(5) # Delay for 5 seconds to avoid IP blocking
related_searches, google_suggest = get_related_searches_and_suggest(suggestion)
max_length = max(len(related_searches), len(google_suggest))
# Pad the shorter lists with empty strings
related_searches += [''] * (max_length - len(related_searches))
google_suggest += [''] * (max_length - len(google_suggest))
# Create a new DataFrame for the additional data
new_data = {'Initial Keyword': [suggestion] * max_length, 'Related Searches': related_searches, 'Google Suggest': google_suggest}
# Concatenate the new DataFrame with the existing one
df = pd.concat([df, pd.DataFrame(new_data)], ignore_index=True)
Executing the Code: Ready to get your hands dirty? Follow our step-by-step instructions for running the Python script, including code snippets for each step. Discover how to customize the keyword and output file name to suit your needs.
# Example: Executing the code
if __name__ == "__main__":
keyword = input("Enter the initial keyword to search for: ")
related_searches, google_suggest = get_related_searches_and_suggest(keyword)
max_length = max(len(related_searches), len(google_suggest))
# Pad the shorter lists with empty strings
related_searches += [''] * (max_length - len(related_searches))
google_suggest += [''] * (max_length - len(google_suggest))
data = {'Initial Keyword': [keyword] * max_length, 'Related Searches': related_searches, 'Google Suggest': google_suggest}
# Create a DataFrame from the data
df = pd.DataFrame(data)
# Export the DataFrame to an Excel file
df.to_excel('google_data_india.xlsx', index=False)
print("Data exported to 'google_data_india.xlsx'")

# Send an HTTP GET request to the Google search URL
