When scraping websites like Amazon, it's essential to mimic a real browser to avoid detection and potential blocking, as web scraping can be against the terms of service of many websites. User agents are one of the key pieces of information that your web scraper sends to a web server to identify the type of device and browser making the request.
Amazon, like many other websites, is very sophisticated in detecting bots and scrapers, so using a common, up-to-date web browser user agent is crucial. Below are some user agents that mimic real browsers as of my last update:
Common User Agents for Web Scraping
Google Chrome on Windows 10:
Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/98.0.4758.102 Safari/537.36

How to Use a User Agent in Python
When scraping with Python, you can use the requests
library and set the User-Agent
header to mimic a real browser. Here is an example:
import requests
url = 'https://www.amazon.com'
headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/98.0.4758.102 Safari/537.36'
}
response = requests.get(url, headers=headers)
# Now you can process the response content
How to Use a User Agent in JavaScript
In JavaScript, if you are using Node.js with a package like axios
, you can also set the User-Agent
in the request headers:
const axios = require('axios');
const url = 'https://www.amazon.com';
const headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/98.0.4758.102 Safari/537.36'
};
axios.get(url, { headers })
.then(response => {
// Handle the response data
})
.catch(error => {
// Handle the error
});
Important Considerations
- Always use the latest user agents, as using an outdated one can be a red flag to websites.
- Websites like Amazon often require more sophisticated scraping techniques, such as managing sessions, handling cookies, and potentially rotating user agents and IP addresses to avoid detection.
- Make sure to comply with Amazon's terms of service and applicable laws regarding scraping. Unauthorized scraping can lead to legal issues and permanent bans from the service.
Remember that scraping should be done responsibly and ethically, respecting the target website's terms and conditions as well as legal restrictions.
