A 301 redirect tells search engines that a page has moved to a new location. This helps keep traffic and ranking from the old page. The redirect should point to the most relevant new page, not just the homepage. It is important to update all internal links to avoid redirect chains, which slow down loading. Testing redirects ensures they work as expected. This process keeps the site clean and user friendly. When many pages are moved, should redirects be done in bulk or step by step?
