During a corporate website redesign, the handling of old links is often overlooked, yet it directly affects user access experience and search engines' trust in the site. If all old links become invalid, bookmarked pages and external links pointing to them will turn into dead links, not only losing potential customers but also potentially causing search engines to lower the site's ranking. So, what information should old links contain? Which ones must be kept? Which can be discarded? This article provides practical recommendations.
1. Prioritize High-Value Pages
Not all old links are worth keeping. Before the redesign, review the old site's URL list and filter based on the following criteria:
- Pages with traffic and conversions: For example, product detail pages, case study pages, and contact pages. These pages directly generate business inquiries and must be retained with 301 redirects to the corresponding new pages.
- Pages referenced by external sites: Use search engines or third-party tools (like Google Search Console) to identify which pages have backlinks. The authority of these links needs to be transferred to the new pages.
- Important brand information pages: Company introduction, certifications, awards, news updates, etc. These pages serve as windows for users to learn about the company and should retain core content.
For low-value pages (such as expired event pages or temporary promotional pages), you can delete them directly, but it's recommended to set up 301 redirects to the homepage or relevant category pages to avoid 404 errors.
2. Set Up 301 Redirects to Transfer Authority
A 301 redirect is the standard way to inform search engines that an old link has permanently moved to a new address. It transfers the authority of the old page to the new one while automatically redirecting users. When implementing, note the following:
- Each old URL should correspond to the most relevant new URL, not all pointing to the homepage, as this dilutes authority and worsens user experience.
- Configure redirects one by one to ensure no omissions. Use the website's redirect feature or server configuration files.
- After configuration, test each old link to ensure it redirects correctly and that the new page loads properly.
3. How to Migrate Information from Old Links
While retaining links, content must also be migrated. It's recommended to fully copy core information from old pages (such as product specifications and case details) to new pages, with appropriate optimization. For duplicate content, merge it into new pages to avoid multiple pages with similar content.
If old pages have user comments or downloadable resources, try to retain or migrate them, as these are website assets.
4. Handle 404 Pages to Improve Experience
Even with proper redirects, 404 errors may still occur due to operational mistakes. Design a user-friendly 404 page that includes a link back to the homepage, a search box, and popular product entries to reduce user loss. Additionally, regularly check website logs and promptly address any 404s found.
5. Continuous Monitoring After Redesign
After the redesigned site goes live, continuously monitor the access status of old links. Use search engine tools to check for 404 errors and whether redirects are effective. It's recommended to monitor for at least one month to ensure all old links redirect correctly.
In summary, handling old links is a critical part of website redesign. Retaining high-value pages, setting up 301 redirects, and migrating effective information will ensure a smooth transition, preserving existing traffic and SEO results.
