Launching a new website is an exciting milestone for any business. Whether it’s driven by a rebrand, new functionalities or a need to improve user experience, the new site should support long-term growth. One thing that is often overlooked and could prevent growth is not sufficiently considering which content is moved from the old site to the new.
The risk of overlooking existing content
Over time, websites build value through content that ranks well in search engines, earns backlinks and consistently brings in organic traffic. When this content is removed, poorly combined or migrated without SEO in mind, performance can drop.
Common issues include a fall in organic traffic, backlinks pointing to broken pages and the loss of keyword rankings that once brought in qualified visitors. These problems are not always obvious straight away, which makes them harder to fix after launch, therefore a structured approach to content migration beforehand helps reduce this risk.
A practical approach to content migration
A successful migration starts with understanding what is already working. This begins with a content audit using tools such as Google Analytics, Google Search Console or an SEO tool, like Ahrefs or SEMRush, if you have one available. Looking at organic traffic, landing page performance, and keyword rankings helps identify which pages contribute most to success.
Each piece of content should then be reviewed on its own. Some pages will still be accurate, relevant and performing well, while others may no longer match the business or audience needs. This stage often highlights opportunities, such as refreshing outdated content or combining similar pages into a stronger single resource.
After the review, content should be grouped based on its role on the new site. This usually means identifying content to migrate as is, content that needs updating before launch, content to combine and content to remove.
From there, priorities should be set based on value. Focus first on pages that drive traffic, generate leads or rank for important search terms. This will make it easier for your team to work through moving key content across if timelines are tight.
Key technical considerations
Content decisions are only part of the process. Technical details play a big role in protecting SEO performance when migrating to a new site.
Redirects
Redirects are essential when URLs change, content is combined, or pages are removed. Without them, users and search engines may land on error pages, which can lead to lost authority and a poor experience. A clear redirect plan should always be in place before launch to avoid performance loss.
Images
Images should also be checked. File names, alt text and image URLs all have an impact on SEO and performance. Migration is a good chance to make sure images are properly optimised and that nothing is missing or broken.
One thing we often see is when a client is manually moving across content, just copying and pasting content without checking images, which can often mean that broken images appear all across your brand-new website, which is not a good look.
Internal Links
Internal links often change during a redesign, but can be overlooked when migrating over old content. Making sure links point to the correct new URLs helps search engines crawl the site more effectively and supports key pages. While redirects will often aid with the bulk of 404s, it’s important to ensure internal linking is direct and relevant where possible for the best user experience.
Monitoring after launch
Once the new site is live, monitoring becomes important. Search engines like Google need time to process changes, so some movement in traffic or rankings is normal. Regular checks will help spot any issues early on and mean you can react quickly if you’re seeing any serious issues arising.
Alongside organic traffic and keyword rankings, it’s also worth checking for crawl errors and 404 pages which are often flagged by Google Search Console or specific SEO tools. In most cases, regularly reviewing performance for the first three months gives a clear picture of how well the migration has gone and whether anything needs to be fixed.
