How do you handle duplicate content issues?
Explanation:
Duplicate content is when identical or very similar content appears on multiple URLs. This can confuse search engines, leading to potential ranking issues or diluted page authority. At a FAANG company, addressing duplicate content involves strategic techniques to ensure that search engines understand which version of a page should be prioritized in search results.
Key Talking Points:
- Canonical Tags: Use canonical tags to inform search engines of the preferred URL for indexing.
- 301 Redirects: Implement 301 redirects to guide users and search engines to the correct page.
- Consistent Internal Linking: Ensure internal links point to the preferred version of the content.
- URL Parameters: Utilize URL parameter handling tools to manage duplicate content from dynamic URLs.
- Syndication: When content is syndicated, ensure proper tags (like rel="nofollow") or agreements are in place to prioritize original content.
