Step 2: Web Search Strategy

Perform targeted searches using the search_web tool:

Amazon Search

Query: "{supplement_name} {form} supplement ADHD {dosage}"
Example: "Omega-3 EPA DHA supplement ADHD 1000mg"

Look for:

• Products with 4+ star ratings
• High review counts (500+)
• "Amazon's Choice" or "Best Seller" badges
• Third-party tested/certified products
• Brands mentioned in search results (Nordic Naturals, NOW Foods, Thorne, etc.)

iHerb Search (Alternative/Backup)

Query: "{supplement_name} {form} highest rated iHerb"

Look for:

• iHerb verified reviews
• Products with detailed supplement facts
• Brand reputation indicators

Step 3: Extract Product Identifiers

For Amazon:

• Extract ASIN (Amazon Standard Identification Number)
  • Found in URL: amazon.com/dp/{ASIN}
  • Example: B001U4OYGY
• Extract product title for verification

For iHerb:

• Extract Product ID
  • Found in URL: iherb.com/{product-id}
  • Example: 81332

Step 4: Generate Affiliate Links

Use the AffiliateService class to generate tagged links:

// For Amazon
final affiliateService = AffiliateService();

// Single region
final usLink = affiliateService.getTaggedAffiliateLink(
  supplementId: 'B001U4OYGY',  // ASIN from Step 3
  region: UserRegion.us,
);

// All regions
final allLinks = affiliateService.getAllRegionLinks('B001U4OYGY');
