Two search engines, two completely different optimization strategies. Understand the key differences and learn which to prioritize for your business.
Amazon SEO optimizes product listings for purchase intent — the algorithm rewards products that sell well (sales velocity, conversion rate, reviews). Google SEO optimizes web pages for information relevance — the algorithm rewards content quality, backlinks, and technical factors (E-E-A-T, Core Web Vitals). Amazon ignores backlinks entirely. Google doesn't care about your sales velocity. They require completely different strategies.
| Factor | Amazon SEO | Google SEO |
|---|---|---|
| Primary Purpose | Help shoppers find and buy products | Deliver the most relevant information |
| User Intent | Transactional (ready to buy) | Informational, navigational, or transactional |
| Algorithm Name | A9 / A10 | Core ranking + helpful content system |
| Top Ranking Signal | Sales velocity + keyword relevance | Backlinks + content quality |
| Content Format | Product listings (title, bullets, images) | Web pages, articles, videos |
| Backlinks | Not a ranking factor | Primary ranking factor |
| Technical SEO | Minimal (no site architecture) | Critical (Core Web Vitals, mobile, schema) |
| Conversion Impact | Directly affects ranking (20% weight) | Indirect — better UX improves engagement signals |
| Reviews/Ratings | Direct ranking factor (10% weight) | Indirect — shown in rich snippets, builds trust |
| Paid Ads Impact | PPC boosts sales velocity → organic rank | Ads have zero impact on organic ranking |
| Time to Results | 2-8 weeks for ranking changes | 3-12 months for competitive keywords |
| Content Length | 200-char title, 5 bullets, 250-byte backend | Long-form content (1500-5000+ words) preferred |
| External Links | External traffic now helps (A10) | Outbound links add topical relevance |
| Mobile Priority | 70%+ traffic is mobile | Mobile-first indexing since 2021 |
| Algorithm Updates | Gradual, less transparency | Named core updates, more transparency |
| E-E-A-T | Not applicable — product quality matters | Critical — expertise, experience, authority, trust |
Under Amazon's A10 algorithm, external traffic from Google now positively impacts Amazon rankings. This creates a powerful synergy:
