Redirect
Quick Definition
A redirect is a server-side instruction that automatically sends users and search engines from one URL to another. Redirects are essential for maintaining SEO equity when pages are moved, renamed, or deleted.
Why It Matters
Redirects are essential for maintaining SEO value when URLs change. Without proper redirects, you lose all the backlinks, social shares, and ranking power that the old URL accumulated. Understanding redirect types is a fundamental technical SEO skill needed for site migrations, URL changes, and content consolidation.
Real-World Example
A company rebrands from oldcompany.in to newcompany.in. Without 301 redirects from every old URL to the corresponding new URL, all their organic traffic and rankings disappear overnight. With proper redirects, the transition preserves most of the SEO value accumulated over years.
Signal Connection
Trust -- Redirects preserve the trust and authority accumulated by the original URL. When backlinks, social shares, and user bookmarks all follow redirects to the new URL, the trust signals transfer rather than being lost.
Pro Tip
Before any URL change, export a complete list of all URLs with their current traffic and backlinks. Set up redirects from old to new URLs, then monitor Google Search Console for crawl errors weekly for at least 3 months after the change.
Common Mistake
Redirecting all old pages to the homepage instead of to the most relevant corresponding page. If /blog/seo-guide gets redirected to the homepage instead of /guides/seo-guide, Google treats it as a soft 404 and the ranking power is wasted. Always redirect to the most relevant equivalent page.

Show Answer
Answer: B. To preserve SEO ranking power and avoid broken links
Redirects ensure that when a URL changes, all the ranking power, backlinks, and traffic associated with the old URL transfer to the new one. Without redirects, users and search engines hit dead ends, and accumulated SEO value is lost.
