I've created a script to collect the different company names from this website using the requests module, but when I execute the script, it ends up getting nothing. I looked for the company names in the page source and found that the names are available there, so they seem to be static.

import requests
from bs4 import BeautifulSoup

link = 'https://clutch.co/agencies/digital-marketing'

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',
}

with requests.Session() as s:
    s.headers.update(headers)
    res = s.get(link)
    soup = BeautifulSoup(res.text,"lxml")
    for item in soup.select("h3.company_info > a"):
        print(item.text)

Since the website's protected by Cloudflare there's a python module called cloudscraper that attempts to bypass Cloudflare's anti-bot page.

Using the module you could be able to get the data you need.

For example:

import cloudscraper
import pandas as pd
from bs4 import BeautifulSoup
from tabulate import tabulate

scraper = cloudscraper.create_scraper()
source_html = scraper.get("https://clutch.co/agencies/digital-marketing").text

soup = BeautifulSoup(source_html, "lxml")
company_data = [
    [item.getText(strip=True), f"https://clutch.co{item['href']}"]
    for item in soup.select("h3.company_info > a")
]

df = pd.DataFrame(company_data, columns=["Company", "URL"])
print(tabulate(df, headers="keys", tablefmt="github", showindex=False))

This should print:

Answer 2

Try This:

from selenium import webdriver
from bs4 import BeautifulSoup
import time

link = 'https://clutch.co/agencies/digital-marketing'


driver = webdriver.Chrome()

# Go to the website
driver.get(link)

# Wait for the page to load
time.sleep(5)

# Get the page source
html = driver.page_source

# Create a BeautifulSoup object
soup = BeautifulSoup(html, 'lxml')

# Find all elements with class "company_info" and extract the text
for item in soup.select("h3.company_info > a"):
    print(item.text)
    
# Close the browser
driver.quit()
