Pro Tips
- A 200 status doesn't mean the page is correct - soft 404s return 200 for error pages
- 301 redirects pass SEO value; 302s may not - use 301 for permanent URL changes
- 503 tells Google to come back later - use during planned maintenance
- 410 is stronger than 404 - use it to tell Google a page is permanently gone
