Before working with Firestarter, Bird Golf had virtually no SEO presence. Their visibility was limited to a few local rankings, leaving them invisible for high-value terms like “2 day golf academy,” “Florida Golf School,” and “Golf Instruction Academy.” This meant thousands of missed opportunities each month to attract new students and bookings.
Solution
Firestarter designed a comprehensive SEO campaign tailored to the golf academy industry: Keyword Targeting – Mapped and implemented strategic keywords across core pages, unlocking 4,000+ monthly searches. Link Building – Built a strong backlink profile through industry directories and relevant sites to establish authority and trust. Optimization – Fixed technical issues, then optimized on-page content with improved titles, descriptions, and keyword placement to maximize search engine clarity
Result
The results were transformative: 1,000+ Ranking Improvements, including 123 first-page keywords such as “3 day golf schools” and “Best Golf Academies.” 100%+ Increase in Organic Traffic, delivering thousands of new site visits. 10X Monthly Leads, establishing Bird Golf as one of the nation’s leading golf academies.

Despite being an established brand since 1983, Colorado Painting faced steep competition in the booming Denver market.

Link Building – Launched a campaign of industry-relevant directories and guest posts to close the gap with competitors. Google Ads – Developed a complementary paid strategy to accelerate leads alongside SEO growth.

The combined SEO and PPC strategy transformed Colorado Painting’s digital presence: 50+ First-Page Rankings, including #1 for “Commercial Painting Denver” and “Residential Painting Denver.” 35% Traffic Growth, exceeding 10,000 monthly visitors. 2,742 Conversions in One Year, firmly reestablishing them as a market leader.
