iHerb Product Scraper: Extract Supplement & Beauty Data at Scale

---

What Is iHerb?

iHerb.com is one of the world's largest online retailers of vitamins, supplements, natural health products, and beauty items. With millions of active SKUs across hundreds of brands, iHerb attracts researchers, competitors, and data analysts seeking product intelligence. Manually extracting product details from individual listings is inefficient — the iHerb Product Scraper automates this workflow, delivering structured data in minutes.

---

Overview

The iHerb Product Scraper extracts detailed product pages from iHerb.com, capturing comprehensive product information and converting it into clean, machine-readable records. It serves:

• Price monitoring teams tracking competitor pricing and promotions
• Supplement researchers analyzing product formulations and availability
• E-commerce aggregators building product databases
• Marketing analysts monitoring product rankings and customer sentiment
• Retailers benchmarking against iHerb's catalog

The scraper handles multiple URLs simultaneously, supports proxy rotation for reliable access, and gracefully manages network failures via the ignore_url_failures flag.

---

Input Format

The scraper accepts a JSON configuration specifying product URLs and collection settings:

{
    "urls": [
        "https://www.iherb.com/pr/medicube-collagen-night-wrapping-mask-2-53-fl-oz-75-ml/150472",
        "https://www.iherb.com/pr/advanced-clinicals-collagen-serum-1-75-fl-oz-52-ml/82178",
        "https://www.iherb.com/pr/eucerin-clear-skin-lightweight-sunscreen-lotion-for-face-spf-50-fragrance-free-2-5-fl-oz-75-ml/113261"
    ],
    "max_items_per_url": 200,
    "ignore_url_failures": true
}

Parameter	Description
urls	Array of direct iHerb product page URLs. Copy from your browser's address bar.
max_items_per_url	Maximum records per URL (default: 200). Limits output size.
ignore_url_failures	If true, scraper continues if some URLs fail; if false, entire run stops on first error.

Best Practice: Use direct product URLs (ending with a product ID number), not search or category pages.

How to Use

1. Gather product URLs — Browse iHerb.com, find products you want to track, and copy individual product page URLs (the full URL in your browser's address bar).

2. Prepare your URL list — Paste URLs into the urls array. You can add 1 or 1,000 URLs; the scraper handles bulk collections.

3. Set collection parameters — Keep max_items_per_url at 200 for full product details. Set ignore_url_failures: true if scraping in bulk to avoid interruptions.

4. Run the scraper — Start the actor and monitor progress. The run log shows successful and failed URLs.

5. Export results — Download output as JSON, CSV, or Excel. Import into spreadsheets, databases, or BI dashboards.

Troubleshooting:

• If a URL returns no data, verify the URL is a product detail page (not a category or search page).
• Product URLs typically contain /pr/ followed by a product name and ID number.
• If getting rate-limited, enable proxy rotation in advanced settings.
