To scrape reviews by product keyword, you typically need to perform web scraping on e-commerce sites (like Amazon, Walmart, BestBuy, etc.), review aggregators, or forums where users leave product feedback. Here’s a high-level breakdown of how you can do this:
1. Define the Product Keyword
Start by identifying your keyword(s). Example: "wireless earbuds"
, "air fryer"
, "laptop stand"
.
2. Identify Target Websites
Choose where you’ll scrape reviews from. Common targets include:
-
Amazon (requires careful handling due to anti-bot mechanisms)
-
Walmart
-
BestBuy
-
Target
-
eBay
-
Google Shopping
-
Reddit or specialized forums
-
Review aggregation platforms (like Trustpilot, ConsumerAffairs)
3. Use a Scraping Tool or Script
Option A: Use Python with BeautifulSoup/Selenium
Example using Google Shopping:
Option B: Use a Web Scraping API (e.g., SerpAPI, ScraperAPI)
These help avoid IP bans and handle captchas.
Example using SerpAPI (free tier available):
4. Store and Clean the Data
Use Pandas to clean and save:
5. (Optional) Use NLP to Analyze Reviews
For example, extract sentiment:
Important Notes
-
Scraping Amazon or similar e-commerce sites directly may violate their terms of service.
-
Use APIs or public sources when possible.
-
Rotate IPs and user agents when doing large-scale scraping.
-
Consider using a headless browser like Selenium or Playwright when JS rendering is required.
If you want a ready-to-use script for a specific platform and keyword, let me know which platform and keyword(s) you’re targeting.
