Combining two websites into one can be a complex task, but with careful planning and execution, it can be streamlined effectively. Firstly, create a sitemap of the website you are merging (site A) to get a clear overview of the content and structure. Then, choose a new domain name that reflects the combined brand and is something you are proud of. Make the new domain live and ensure that all URLs are mapped correctly, using 301 redirects to preserve search engine rankings and traffic. Update internal links throughout the website to reflect the new domain structure. Finally, move the entire site to the new domain, ensuring that the content and functionality remain intact. By following these steps, you can successfully merge two websites into one, providing a unified brand experience for your audience.
