📌Note: If some results are not being retrieved, then some selectors have been changed by Google.

Using Google Shopping Results API

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

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

Example code to integrate:

from serpapi import GoogleSearch
import requests, lxml, json

params = {
    "q": "shoes",  						# search query
    "tbm": "shop",  					# shop results
    "location": "Dallas",  				# location from where search comes from
    "hl": "en",  						# language of the search
    "gl": "us",  						# country of the search
    "api_key": "..."                    # https://serpapi.com/manage-api-key
}

# 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/103.0.0.0 Safari/537.36"
}

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


def download_google_shopping_images():
    for index, result in enumerate(results["shopping_results"], start=1):
        image = requests.get(result['thumbnail'], headers=headers, timeout=30, stream=True)

        if image.status_code == 200:
            with open(f"images/image_{index}.jpeg", 'wb') as file:
                file.write(image.content)


def serpapi_get_google_shopping_data():
    google_shopping_data = results["shopping_results"]

	# download_google_shopping_images()
	
    print(json.dumps(google_shopping_data, indent=2, ensure_ascii=False))

Outputs:

Prerequisites

Install libraries:

pip install requests parsel google-search-results

google-search-results is a SerpApi API package that will be shown at the end as an alternative solution.

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, re
from parsel import Selector
from serpapi import GoogleSearch
Library Purpose
Selector XML/HTML parser that have full XPath and CSS selectors support.
requests to make a request to the website.
lxml to process XML/HTML documents fast.
json to convert extracted data to a JSON object.
re to extract parts of the data via regular expression.

Create URL parameter and request headers:

# https://docs.python-requests.org/en/master/user/quickstart/#passing-parameters-in-urls
params = {
    "q": "shoes",
    "hl": "en",     # language
    "gl": "us",     # country of the search, US -> USA
    "tbm": "shop"   # google search shopping
}

# 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/103.0.0.0 Safari/537.36"
}
Code Explanation
params a prettier way of passing URL parameters to a request.
user-agent to act as a "real" user request from the browser by passing it to request headers. Default requests user-agent is a python-reqeusts so websites might understand that it's a bot or a script and block the request to the website. Check what's your user-agent.

Make a request, pass created request parameters and headers. Request returned HTML to Selector:

html = requests.get("https://www.google.com/search", params=params, headers=headers, timeout=30)
selector = Selector(html.text)
Code Explanation
timeout=30 to stop waiting for response after 30 seconds.
Selector() where returned HTML data will be processed by parsel.

Get original images

To find a proper thumbnail resolution, we need to open the page's source code (CTRL+U) and look for the <script> tags that contain image IDs and image URLs in an encoded state. We need an image ID also to extract the right listing image, not some random one.

You can directly parse the data from the img tag and the src attribute, but you will get a base64 encoded URL that will be a 1x1 image placeholder. Not a particularly useful image resolution.

First of all, you need to select all <script> tags. To find them, you can use the css() parsel method. This method will return a list of all matched <script> tags.

all_script_tags = "".join(
    [
        script.replace("</script>", "</script>\n")
        for script in selector.css("script").getall()
    ]
)
Code Explanation
"".join() to concatenate a list into a string.
replace() to replace all occurrences of the old substring with the new one so that the regular expression is executed correctly.
getall() to return a list with all results.

Next, our task is to find the script tags containing information about the image URL and its ID. To do this, we can use a for loop and iterate the list of matched elements.

The for loop iterates through all the images on the page (except for ads or shop offers) and find the ID of the current image in the all_script_tags list using regular expression in order to extract a specific image, not a random one, by checking its ID var _i:

for result in selector.css(".Qlx7of .sh-dgr__grid-result"):
    # https://regex101.com/r/udjFUq/1
    url_with_unicode = re.findall(rf"var\s?_u='(.*?)';var\s?_i='{result.attrib['data-pck']}';", all_script_tags)

Here's a regular expression example to extract image URL and its ID from a <script> tags:

Instead of \d+, you need to substitute the data-pck attribute that stores the id of the image. For this, we will use a formatted string:

url_with_unicode = re.findall(rf"var\s?_u='(.*?)';var\s?_i='{result.attrib['data-pck']}';", all_script_tags)

The regular expression returned the URL of the image in an encoded state. In this case, you need to decode Unicode entities. After the performed operations, add the address to the image_urls list:

url_decode = bytes(url_with_unicode[0], 'ascii').decode('unicode-escape')
image_urls.append(url_decode)

The function looks like this:

def get_original_images():
    all_script_tags = "".join(
        [
            script.replace("</script>", "</script>\n")
            for script in selector.css("script").getall()
        ]
    )
	
    image_urls = []
    
    for result in selector.css(".Qlx7of .sh-dgr__grid-result"):
        # https://regex101.com/r/udjFUq/1
        url_with_unicode = re.findall(rf"var\s?_u='(.*?)';var\s?_i='{result.attrib['data-pck']}';", all_script_tags)

        if url_with_unicode:
            url_decode = bytes(url_with_unicode[0], 'ascii').decode('unicode-escape')
            image_urls.append(url_decode)
            		
	# download_original_images(image_urls)	
	
    return image_urls

Download original images

We now have a list with all the correct URLs. We use the same for loop with the enumerate() built-in function. This function adds a counter to an iterable and returns it. The counter is needed to assign a unique number to each image at the saving stage (if you need to save them).

In each iteration of the loop, you must follow the current link and download the image. You can use with open() context manager to save the image locally.

def download_original_images(image_urls):
	for index, image_url in enumerate(image_urls, start=1):
		image = requests.get(image_url, headers=headers, timeout=30, stream=True)
	
		if image.status_code == 200:
			print(f"Downloading {index} image...")

			with open(f"images/image_{index}.jpeg", "wb") as file:
				file.write(image.content)

In the gif below, I demonstrate how this function works:

📌Note: You may notice that the images do not load in the same order they appear on the site. This is because Google renders pages for each user in a unique way based on their location, search history, etc. You can learn more by reading this post: Reasons Google Search Results Vary Dramatically.

Get suggested search data

In this function, I use the zip() built-in function, which allows you to iterate through two iterables at once, the first iterable is the selector of all product listings, the second is an list of thumbnail URLs returned by the get_original_images() function.

You may notice that some data may be missing from some product cards:

This function uses the Parsel library to avoid the use of exceptions. If you try to parse non-existent data, the value will automatically be written to None and the program will not stop. As a result, all information about the product is added to google_shopping_data list:

def get_suggested_search_data():
    google_shopping_data = []
    
    for result, thumbnail in zip(selector.css(".Qlx7of .i0X6df"), get_original_images()):
        title = result.css(".tAxDx::text").get()		
        product_link = "https://www.google.com" + result.css(".Lq5OHe::attr(href)").get()

Code Explanation
google_shopping_data a temporary list where extracted data will be appended at the end of the function.
zip() to iterate over multiple iterables in parralel. Keep in mind that zip is used on purpose. zip() ends with the shortest iterator while zip_longest() iterates up to the length of the longest iterator.
css() to access elements by the passed selector.
::text or ::attr(<attribute>) to extract textual or attribute data from the node.
get() to actually extract the textual data.
search() to search for a pattern in a string and return the corresponding match object.
group() to extract the found element from the match object.
google_shopping_data.append({}) to append extracted images data to a list as a dictionary.
