Spanish pages covered a gap no competitor had.
Glendale has a 43% Hispanic/Latino population. Sunset HVAC's previous site was English-only. Three of the top 5 HVAC searches in Glendale have Spanish-language intent.
We built full Spanish versions of all 5 pages, accessible via a lang toggle in the nav. The Spanish content was written to sound natural, not machine-translated. Service-area page for Glendale has both EN and ES versions with separate schema markup.
The bilingual setup is part of the Studio tier at no extra cost.
Site live. Scoring above competitors.
