WordPress Developer Needed to Migrate Existing with Full SEO Preservation

We are looking for an experienced WordPress developer or small web-development agency to migrate an existing company website from a custom-built C# system to WordPress. The company manufactures industrial digital printing machinery. The website includes product and machine pages, application pages, technical information, news, videos, downloadable brochures, contact forms and multilingual content. This is not a simple template installation. We need a complete, professional WordPress system that is fast, secure, easy for our team to manage and properly prepared for SEO and AI search visibility. The current website address will be shared with shortlisted candidates. ### Project Objectives The selected developer will be responsible for: * Auditing the existing website and its content * Creating a complete inventory of existing URLs * Migrating all relevant pages, content, images, videos and downloadable files * Rebuilding the website in WordPress * Preserving existing SEO value and rankings * Creating a fast, mobile-responsive and technically clean website * Building an easy-to-manage backend for our internal team * Collaborating with our graphic designer on the visual design * Preparing the complete website for launch ### Required WordPress Structure The website should use structured content rather than treating everything as a basic page. We expect appropriate WordPress content structures for areas such as: * Machines and products * Applications * Printing technologies * Industries * Case studies and installations * News and exhibitions * Technical articles * Videos * Brochures and downloads * Company locations and contact information Machine pages should support structured information such as: * Machine name * Description * Printing width * Production speed * Printhead technology * Ink type * Compatible materials * Applications * Technical specifications * Images * Videos * Brochures * Related machines and technologies * Inquiry forms The system should make it easy for us to add new machines, applications and articles without rebuilding pages manually. ### Design and Development Requirements * Custom, professional WordPress implementation * Collaboration with our graphic designer * Responsive design for desktop, tablet and mobile * Clean and lightweight frontend * Reusable page sections or blocks * Server-rendered, crawlable content * Minimal unnecessary JavaScript * No cheap multipurpose theme * No excessive plugin usage * No dependence on unsupported or pirated plugins * Easy content management for non-technical users * Staging and production environments We prefer Gutenberg or another clean and maintainable WordPress editing system. We do not want a slow website overloaded with page-builder plugins. ### Multilingual Requirements The existing website contains multiple languages. The new WordPress system must properly support multilingual content. This includes: * Separate URLs for each language * Correct hreflang implementation * Language-specific menus * Language-specific metadata * Correct canonical tags * Easy translation management * No automatic IP-based redirects that prevent crawling * Proper multilingual XML sitemaps Please explain which multilingual solution you recommend and why. ### SEO Migration Requirements SEO preservation is a critical part of this project. The developer must: * Crawl and audit the existing website before migration * Create a complete old-to-new URL mapping * Preserve important URL structures where practical * Implement individual 301 redirects * Avoid redirecting all old pages to the homepage * Preserve or improve page titles and meta descriptions * Implement canonical tags * Configure XML sitemaps * Configure robots.txt * Implement breadcrumbs * Add appropriate structured data and JSON-LD * Optimize heading structure * Preserve image alt text where available * Prevent duplicate or thin pages * Configure Google Search Console * Configure Google Analytics * Test redirects and crawlability before launch * Monitor indexing and errors after launch Experience with multilingual SEO migrations is strongly preferred. ### SEO and AI Search Readiness The new website should be technically prepared for traditional search engines and generative search platforms. Important information must be available directly in the HTML and should not exist only inside images, animations or PDF brochures. The website should include appropriate structured data for: * Organization * Products * Articles * Technical articles * Videos * Breadcrumbs * Locations * Authors where applicable Relevant legitimate search crawlers should not be accidentally blocked. ### Performance Requirements The completed website should be optimized for: * Fast loading times * Core Web Vitals * Mobile performance * Image compression and next-generation image formats * Lazy loading where appropriate * Full-page caching * Browser caching * CDN integration * Database optimization * Minimal plugin and script bloat Please include examples of websites you have built that perform well in Google PageSpeed Insights or Core Web Vitals. ### Hosting, Security and Maintenance The developer should recommend and configure an appropriate managed WordPress hosting environment. The setup should include: * SSL * CDN * Web application firewall * Daily backups * Off-site backup storage * Two-factor authentication * Limited administrator access * Staging environment * Malware and security monitoring * Update and rollback procedures * Spam protection for forms * Uptime monitoring Please also provide an optional ongoing maintenance proposal after launch. ### Forms and Tracking The website will require professional inquiry forms, including product-specific inquiries. Forms should: * Send reliable email notifications * Store submissions securely * Identify which machine or application generated the inquiry * Include spam protection * Support conversion tracking * Be prepared for future CRM integration ### Expected Deliverables The final delivery must include: * Fully functional WordPress website * Migrated and organized content * Responsive frontend * Multilingual setup * SEO migration and redirect implementation * Performance optimization * Security configuration * Analytics and Search Console setup * Form configuration and testing * Staging and production setup * Administrator documentation * Training session for our team * Backup and rollback plan * Post-launch support period * Full transfer of code, licenses, credentials and ownership The website will not be considered complete until the important pages, forms, downloads, languages, redirects and tracking systems have been tested. ### Required Experience Applicants should have proven experience with: * WordPress development * Custom WordPress themes or block development * Custom post types and structured content * Multilingual WordPress websites * SEO-sensitive website migrations * 301 redirect mapping * Technical SEO * Structured data * Core Web Vitals * Website security * Managed WordPress hosting * Migrating websites from custom CMS platforms Industrial, manufacturing, engineering or B2B website experience is a major advantage. ### Application Instructions Please answer the following questions in your proposal: 1.
