The Answer To This Interview Question:
Faceted navigation allows users to filter products based on attributes like size, color, or price. While this improves user experience, it can create duplicate content and overwhelm search engine crawlers. In e-commerce SEO, managing faceted navigation involves selectively allowing facets to be indexed while blocking unnecessary or stackable facets to avoid low-value, thin content pages. Strategies include canonical tags, noindex directives, robots.txt rules, and parameter handling in Google Search Console.
What The Interviewer Really Wants To Hear:
Interviewers are looking for your ability to strike a balance between maintaining a great user experience and ensuring crawl budget efficiency by preventing duplicate or thin content issues from faceted navigation.
