#google #webscraping #python

What Is Google Trends?

Google Trends is a free online tool provided by Google that analyzes the popularity of specific keywords or search terms in the Google search engine over time.

It presents data in the form of charts to help users understand the search popularity of a certain topic or keyword, and identifies patterns such as seasonal fluctuations, emerging trends, or declining interest. Google Trends not only supports global data analysis, but also can be refined to specific regions and provide recommendations for related search terms and topics.

Google Trends is widely used in market research, content planning, SEO optimization, and user behavior analysis, helping users make more informed decisions based on data.

How to Scrape Google Trends Data With Python - Step by Step Guide

For example: In this article, let's scrape the Google search trends of 'DOGE' from the previous month.

Google search trends of DOGE

Step 1: Prerequisites

Install Python

On Windows

Using the Official Python Installer

Step 1. Download Python Installer:

  • Go to the official Python website.
  • The website should automatically suggest the latest version for Windows. Click the Download Python button to download the installer.

Step 2. Run the Installer:

  • Open the downloaded .exe file to start the installation process.

Step 3. Customize Installation (optional):

  • Make sure to check the box that says "Add Python to PATH" at the beginning of the installation window. This makes Python accessible from the command line (cmd or PowerShell).
  • You can also click "Customize installation" to choose additional features like pip, IDLE, or documentation.

Step 4. Install Python:

  • Click Install Now to install Python with the default settings.
  • After installation, you can verify it by opening Command Prompt (cmd) and typing: 
python --version
Enter fullscreen mode Exit fullscreen mode

Step 5. Installing pip (if needed):

  • Pip, the Python package manager, is installed by default with modern versions of Python. You can check if pip is installed by typing: 
pip --version
Enter fullscreen mode Exit fullscreen mode

You can also install Python directly from the Windows Store (available on Windows 10/11). Simply search for "Python" in the Microsoft Store app and choose the version you need.

On macOS

Method 1. Using Homebrew (Recommended)

Step 1. Install Homebrew (if not already installed):

  • Open the Terminal app.
  • Paste the following command to install Homebrew (package manager for macOS): 
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
Enter fullscreen mode Exit fullscreen mode

Step 2. Install Python with Homebrew:

  • Once Homebrew is installed, you can install Python with this command: 
brew install python
Enter fullscreen mode Exit fullscreen mode

Step 3. Verify Installation:

  • After installation, you can verify Python and pip versions with the following commands: 
python3 --version
pip3 --version
Enter fullscreen mode Exit fullscreen mode

Method 2. Using the Official Python Installer

Step 1. Download the macOS Installer:

  • Go to the Python Downloads Page.
  • Download the latest macOS installer for Python.

Step 2. Run the Installer:

Using Python via Anaconda (Cross-platform)

Anaconda is a popular distribution for scientific computing and comes with Python, libraries, and the conda package manager.

Step 1. Download Anaconda:

  • Visit the Anaconda Downloads Page and download the appropriate version for your platform.

Step 2. Install Anaconda:

  • Follow the installation instructions based on your operating system. Anaconda provides a graphical installer for both Windows and macOS, as well as command-line installers for all platforms.

Step 3. Verify Installation:

  • After installation, open a terminal (or Anaconda Prompt on Windows) and check if Python is working: 
python --version
Enter fullscreen mode Exit fullscreen mode
  • You can also verify conda (the package manager for Anaconda): 
conda --version
Enter fullscreen mode Exit fullscreen mode

Managing Python Versions (optional)

If you need to manage multiple Python versions on the same machine, you can use version managers:

  • pyenv: A popular Python version manager that works on Linux and macOS.
    • Install via Homebrew or GitHub (for Linux and macOS).
    • On Windows, you can use pyenv-win. 
pyenv install 3.9.0
pyenv global 3.9.0
Enter fullscreen mode Exit fullscreen mode

Access to Scrapeless API and Google trends

Since we have not yet developed a third-party library for use, you only need to install requests to experience the scrapeless API service

pip install requests
Enter fullscreen mode Exit fullscreen mode

Step 2: Configure the code fields that need

Write the code

Next, we need to know how to obtain the data we need through configuration:

  • Keyword: In this example, our keyword is 'DOGE' (we also support the collection of multiple keyword comparison data)
  • Data configuration:
    • Country: Query country, the default is 'Worldwide'
    • Time: Time period
    • Category: Type
    • Property: Source

Step 3: Extracting data

Now, let's get the target data using Python code:

import json
import requests


class Payload:
    def __init__(self, actor, input_data, proxy):
        self.actor = actor
        self.input = input_data
        self.proxy = proxy


def send_request(data_type, search_term):
    host = "api.scrapeless.com"
    url = f"https://{host}/api/v1/scraper/request"
    token = "scrapeless-api-key"  # TODO:use your api key

    headers = {"x-api-token": token}

    input_data = {
        "q": search_term,
        "date": "today 1-m",
        "data_type": data_type,
        "hl": "en-sg",
        "tz": "-480",
        "geo": "",
        "cat": "",
        "property": "",
    }

    proxy = {
        "country": "ANY",
    }

    payload = Payload("scraper.google.trends", input_data, proxy)

    json_payload = json.dumps(payload.__dict__)

    response = requests.post(url, headers=headers, data=json_payload)

    if response.status_code != 200:
        print("Error:", response.status_code, response.text)
        return

    print("body", response.text)


if __name__ == "__main__":
    send_request(data_type="interest_over_time", search_term="DOGE")
Enter fullscreen mode Exit fullscreen mode
  • Output: 
{"interest_over_time":{"averages":[],"timelineData":[{"formattedAxisTime":"24 Nov","formattedTime":"24 Nov 2024","formattedValue":["85"],"hasData":[true],"time":"1732406400","value":[85]},{"formattedAxisTime":"25 Nov","formattedTime":"25 Nov 2024","formattedValue":["89"],"hasData":[true],"time":"1732492800","value":[89]},{"formattedAxisTime":"26 Nov","formattedTime":"26 Nov 2024","formattedValue":["68"],"hasData":[true],"time":"1732579200","value":[68]},{"formattedAxisTime":"27 Nov","formattedTime":"27 Nov 2024","formattedValue":["60"],"hasData":[true],"time":"1732665600","value":[60]},{"formattedAxisTime":"28 Nov","formattedTime":"28 Nov 2024","formattedValue":["49"],"hasData":[true],"time":"1732752000","value":[49]},{"formattedAxisTime":"29 Nov","formattedTime":"29 Nov 2024","formattedValue":["55"],"hasData":[true],"time":"1732838400","value":[55]},{"formattedAxisTime":"30 Nov","formattedTime":"30 Nov 2024","formattedValue":["54"],"hasData":[true],"time":"1732924800","value":[54]},{"formattedAxisTime":"1 Dec","formattedTime":"1 Dec 2024","formattedValue":["55"],"hasData":[true],"time":"1733011200","value":[55]},{"formattedAxisTime":"2 Dec","formattedTime":"2 Dec 2024","formattedValue":["64"],"hasData":[true],"time":"1733097600","value":[64]},{"formattedAxisTime":"3 Dec","formattedTime":"3 Dec 2024","formattedValue":["57"],"hasData":[true],"time":"1733184000","value":[57]},{"formattedAxisTime":"4 Dec","formattedTime":"4 Dec 2024","formattedValue":["61"],"hasData":[true],"time":"1733270400","value":[61]},{"formattedAxisTime":"5 Dec","formattedTime":"5 Dec 2024","formattedValue":["100"],"hasData":[true],"time":"1733356800","value":[100]},{"formattedAxisTime":"6 Dec","formattedTime":"6 Dec 2024","formattedValue":["84"],"hasData":[true],"time":"1733443200","value":[84]},{"formattedAxisTime":"7 Dec","formattedTime":"7 Dec 2024","formattedValue":["79"],"hasData":[true],"time":"1733529600","value":[79]},{"formattedAxisTime":"8 Dec","formattedTime":"8 Dec 2024","formattedValue":["72"],"hasData":[true],"time":"1733616000","value":[72]},{"formattedAxisTime":"9 Dec","formattedTime":"9 Dec 2024","formattedValue":["64"],"hasData":[true],"time":"1733702400","value":[64]},{"formattedAxisTime":"10 Dec","formattedTime":"10 Dec 2024","formattedValue":["64"],"hasData":[true],"time":"1733788800","value":[64]},{"formattedAxisTime":"11 Dec","formattedTime":"11 Dec 2024","formattedValue":["63"],"hasData":[true],"time":"1733875200","value":[63]},{"formattedAxisTime":"12 Dec","formattedTime":"12 Dec 2024","formattedValue":["59"],"hasData":[true],"time":"1733961600","value":[59]},{"formattedAxisTime":"13 Dec","formattedTime":"13 Dec 2024","formattedValue":["54"],"hasData":[true],"time":"1734048000","value":[54]},{"formattedAxisTime":"14 Dec","formattedTime":"14 Dec 2024","formattedValue":["48"],"hasData":[true],"time":"1734134400","value":[48]},{"formattedAxisTime":"15 Dec","formattedTime":"15 Dec 2024","formattedValue":["43"],"hasData":[true],"time":"1734220800","value":[43]},{"formattedAxisTime":"16 Dec","formattedTime":"16 Dec 2024","formattedValue":["48"],"hasData":[true],"time":"1734307200","value":[48]},{"formattedAxisTime":"17 Dec","formattedTime":"17 Dec 2024","formattedValue":["55"],"hasData":[true],"time":"1734393600","value":[55]},{"formattedAxisTime":"18 Dec","formattedTime":"18 Dec 2024","formattedValue":["52"],"hasData":[true],"time":"1734480000","value":[52]},{"formattedAxisTime":"19 Dec","formattedTime":"19 Dec 2024","formattedValue":["63"],"hasData":[true],"time":"1734566400","value":[63]},{"formattedAxisTime":"20 Dec","formattedTime":"20 Dec 2024","formattedValue":["64"],"hasData":[true],"time":"1734652800","value":[64]},{"formattedAxisTime":"21 Dec","formattedTime":"21 Dec 2024","formattedValue":["47"],"hasData":[true],"time":"1734739200","value":[47]},{"formattedAxisTime":"22 Dec","formattedTime":"22 Dec 2024","formattedValue":["44"],"hasData":[true],"time":"1734825600","value":[44]},{"formattedAxisTime":"23 Dec","formattedTime":"23 Dec 2024","formattedValue":["44"],"hasData":[true],"time":"1734912000","value":[44]},{"formattedAxisTime":"24 Dec","formattedTime":"24 Dec 2024","formattedValue":["46"],"hasData":[true],"isPartial":true,"time":"1734998400","value":[46]}]}}

FAQs

Is it legal to scrape Google Trends?

Yes, it is completely legal to scrape the global, publicly available Google Trends data. However, please don't damage your site by sending too many requests in a short period of time.

Is Google Trends misleading?

Google Trends is not a complete reflection of search activity. Google Trends filters out certain types of searches, such as searches that are performed by very few people. Trends only shows data for popular terms, so terms with low search volume will show as "0"

Does Google Trends provide an API?

No, Google Trends does not yet provide a public API. However, you can access Google Trends data from private APIs in third-party developer tools, such as Scrapeless.

Final Thoughts

Google Trends is a valuable data integration tool that provides keyword analysis and popular search topics by analyzing search queries on search engines. In this article, we show in depth how to scrape Google Trends using Python.

However, scraping Google Trends using python coding always encounters the CAPTCHA obstacle. It makes your data extraction particularly difficult. Although the Google Trends API is not available, the Scrapeless Google Trends API will be your ideal tool!
