Scrape Google Product Specs Results with Python

What will be scraped

📌Note: In the DIY solution, I only scrape all specs. If you also want to extract the product title, extensions, description, and others from this page, you can check out the Scrape Google Product Page with Python blog where I described how to extract this data.

Using Google Specs Results API from SerpApi

This section is to show the comparison between the DIY solution and our solution.

The main difference is that it's a quicker approach. Google Specs Results API will bypass blocks from search engines and you don't have to create the parser from scratch and maintain it.

First, we need to install google-search-results:

pip install google-search-results

Import the necessary libraries for work:

from serpapi import GoogleSearch
import json

Next, we write the necessary parameters for making a request:

params = {
    'api_key': '...',                       # https://serpapi.com/manage-api-key
    'engine': 'google_product',             # SerpApi search engine	
    'product_id': '14019378181107046593',   # product id
    'specs': True,                          # more specs, could be also set as '1` which is the same as True
    'hl': 'en',                             # language
    'gl': 'us'                              # country of the search, US -> USA
}

We then create a search object where the data is retrieved from the SerpApi backend. In the results dictionary we get data from JSON:

search = GoogleSearch(params)   # where data extraction happens on the SerpApi backend
results = search.get_dict()     # JSON -> Python dict

In addition to all specs, API also allows you to retrieve data about the product itself (title, extensions, description, etc). All you need is to access the corresponding key:

specs_results = {
    'product_results': results['product_results'],
    'specs_results': results['specs_results']
}

After reviewing the playground, you will be able to understand which keys you can turn to.

Example code to integrate:

from serpapi import GoogleSearch
import json

params = {
    'api_key': '...',                       # https://serpapi.com/manage-api-key
    'engine': 'google_product',             # SerpApi search engine	
    'product_id': '14019378181107046593',   # product id
    'specs': True,                          # more specs, could be also set as '1` which is the same as True
    'hl': 'en',                             # language
    'gl': 'us'                              # country of the search, US -> USA
}

search = GoogleSearch(params)               # where data extraction happens on the backend
results = search.get_dict()                 # JSON -> Python dict

specs_results = {
    'product_results': results['product_results'],
    'specs_results': results['specs_results']
}

print(json.dumps(specs_results, indent=2, ensure_ascii=False))

Output:

import requests, json
from parsel import Selector


def get_specs_results(url, headers):
    html = requests.get(url, headers=headers)
    selector = Selector(html.text)

    data = {}

    for result in selector.css('tr'):
        if result.css('.c18cu'):
            category = result.css('.c18cu::text').get() 
            data[category] = {}
        else:
            key = result.css('.ipBhab::text').get()
            value = result.css('.AnDf0c::text').get()
            data[category][key] = value

    return data


def main():
    # https://docs.python-requests.org/en/master/user/quickstart/#custom-headers
    headers = {
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/107.0.0.0 Safari/537.36'
    }

    URL = 'https://www.google.com/shopping/product/14019378181107046593/specs?hl=en&gl=us'

    specs_results = get_specs_results(URL, headers)

    print(json.dumps(specs_results, indent=2, ensure_ascii=False))


if __name__ == "__main__":
    main()

Preparation

Install libraries:

pip install requests parsel

Reduce the chance of being blocked

Make sure you're using request headers user-agent to act as a "real" user visit. Because default requests user-agent is python-requests and websites understand that it's most likely a script that sends a request. Check what's your user-agent.

There's a how to reduce the chance of being blocked while web scraping blog post that can get you familiar with basic and more advanced approaches.

Code Explanation

Import libraries:

import requests, json
from parsel import Selector

At the beginning of the main() function, the headers and URL are defined. This data is then passed to the get_specs_results(URL, headers) function to form a request and extract information.

The specs_results dictionary contains the received data that this function returns. At the end of the function, the data is output in JSON format:

def main():
    # https://docs.python-requests.org/en/master/user/quickstart/#custom-headers
    headers = {
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/107.0.0.0 Safari/537.36'
    }

    URL = 'https://www.google.com/shopping/product/14019378181107046593/specs?hl=en&gl=us'

    specs_results = get_specs_results(URL, headers)

    print(json.dumps(specs_results, indent=2, ensure_ascii=False))

This code uses the generally accepted rule of using the __name__ == "__main__" construct:

if __name__ == "__main__":
    main()

This check will only be performed if the user has run this file. If the user imports this file into another, then the check will not work. You can watch the video Python Tutorial: if name == 'main' for more details.

Let's take a look at the get_specs_results(url, headers) function mentioned earlier. This function takes url and headers parameters to create a request. Now we need to parse the HTML from the Parsel package, into which we pass the HTML structure that was received after the request:

def get_specs_results(url, headers):
    html = requests.get(url, headers=headers)
    selector = Selector(html.text)

The data dictionary in which the data will be stored is defined:

data = {}

Each product has different categories and parameters. To retrieve data, you first need to find all the table rows and iterate over them:

for result in selector.css('tr'):
    # data extraction will be here

There is a check inside the loop: if the current table row is a category, then we create a key in the dictionary and write an empty dictionary there, else we add the extracted data to this category:

if result.css('.c18cu'):
    category = result.css('.c18cu::text').get() 
    data[category] = {}
else:
    key = result.css('.ipBhab::text').get()
    value = result.css('.AnDf0c::text').get()
    data[category][key] = value

I'm attaching a picture showing what I'm talking about:

At the end of the function, the data dictionary is returned.
