Background
When temperature accuracy is critical, Cleveland Electric Laboratories builds the sensors and systems industries depend on. For more than a century, CEL has manufactured custom thermocouples and temperature-sensing solutions for aerospace, power generation, heat treatment, glass, steel, and other demanding environments. Its capabilities include high-temperature, noble metal, MgO, and vacuum furnace thermocouples, supported by accredited calibration and certification services.
The Opportunity
CEL’s expertise spans far beyond a standard product catalog, but that depth was not always easy to see online. The opportunity was to organize its capabilities around the industries, temperature ranges, certifications, and performance requirements that engineers use to evaluate a thermocouple manufacturer.
Building The Growth Engine
Advan built an SEO strategy around the technical searches engineers use throughout the specification process. We optimized core product and industry pages, expanded content around thermocouple types and applications, strengthened the site’s technical foundation, and increased visibility for the certifications and capabilities that set CEL apart.

Measurable Results
CEL is gaining ground where technical buyers begin their research, with strong rankings across thermocouple products, materials, applications, and testing requirements.
- 900+ Organic keyword rankings
- 20+ Top-three rankings
- 105+ Top-ten rankings
Precision That Performs
By aligning CEL’s online presence with the way engineers search for temperature sensing solutions, Advan is helping the company connect with more qualified opportunities in industries where accuracy, certification, and reliability matter most.
