How can I scrape Nordstrom without affecting my IP address reputation?

Scraping websites like Nordstrom requires careful consideration of legal and ethical issues, as well as technical measures to prevent IP address reputation damage. Before attempting to scrape Nordstrom or any similar website, ensure that you are compliant with their Terms of Service and any applicable laws, such as the Computer Fraud and Abuse Act in the United States.

Here are some general guidelines and techniques to scrape a website without affecting your IP address reputation:

1. Respect robots.txt

Check Nordstrom's robots.txt file to see which parts of the website are permitted to be scraped. You can usually find this file at

2. Use Headers

Make your requests look like they are coming from a browser by setting appropriate headers, including User-Agent.

3. Rate Limiting

Limit the rate of your requests to avoid overwhelming the server. You should mimic human browsing behavior as much as possible.

4. Use Proxies or VPNs

Rotate different IP addresses using proxy servers or VPNs to avoid your IP address being flagged.

5. Use a Headless Browser (if necessary)

Some websites require JavaScript rendering to access the content. Use a headless browser like Puppeteer or Selenium if this is the case.

6. Caching

Cache responses locally to avoid making redundant requests to pages you’ve already scraped.

7. Handle Errors Gracefully

If you receive an error response (like a 429 Too Many Requests), handle it properly by backing off for a while before trying again.

Example Code Snippets

Python with requests and beautifulsoup4

import requests
from bs4 import BeautifulSoup
from time import sleep
from itertools import cycle
import random

# List of User-Agents
user_agents = [...]
# List of Proxies
proxies = [...]

proxy_pool = cycle(proxies)

headers = {
    'User-Agent': random.choice(user_agents),

def scrape(url, headers):
    proxy = next(proxy_pool)
        response = requests.get(url, headers=headers, proxies={"http": proxy, "https": proxy})
        # Ensure you respect the status code, e.g., 429, 503, etc.
        if response.status_code == 200:
            soup = BeautifulSoup(response.content, 'html.parser')
            # Your scraping logic here
            # Handle non-success status codes
    except requests.exceptions.RequestException as e:
        # Handle request exception
    sleep(random.uniform(1, 5))  # Random sleep to mimic human behavior

# Example usage
url = ''
scrape(url, headers)

JavaScript with puppeteer

const puppeteer = require('puppeteer');
const useProxy = require('puppeteer-page-proxy');

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();

  // Rotate proxies and user agents
  await useProxy(page, '');
  await page.setUserAgent('your-user-agent-string');

  try {
    await page.goto('', { waitUntil: 'networkidle2' });
    // Your scraping logic here
    // ...
  } catch (error) {

  await browser.close();

Important Considerations

  • Always check the robots.txt file and respect the disallowed paths.
  • Do not scrape at a high rate; this can cause strain on Nordstrom's servers and get your IP address banned.
  • Ensure you're not violating any terms or laws.
  • Use scraping tools and techniques responsibly.
  • Consider using official APIs if available, as they are a more reliable and legal means to access data.

Lastly, the information provided here is for educational purposes. It's crucial to understand that scraping can have legal implications, and you should proceed with caution and respect for the website's rules and data privacy regulations.
