We executed a full-scale technical SEO and performance optimization for Composite Tech, a global manufacturer of equipment and production lines for composite (fiberglass) rebar. The project focused on resolving deep technical SEO issues, enhancing site performance, improving multilingual structure, and boosting search visibility. Before optimization, the website suffered from slow loading speed, unoptimized images, incorrect hreflang and canonical tags, poor internal linking, missing structured data, and incomplete meta information. Our team developed and implemented a strategy aimed at improving technical health, user experience, and multilingual SEO consistency, leading to significant growth in visibility and engagement.
