20,000+
Keywords developed
The credit union's SEO campaign began with almost no existing keyword base, requiring Pearl Lemon to build a complete keyword ecosystem from scratch. The primary challenge was to identify, clean, and validate a massive keyword universe that would drive growth and high-quality inbound leads.
Pearl Lemon collected competitor keywords using SEMrush, Google Keyword Planner, and KeywordTool.io, exporting over 20,000 terms. They meticulously cleaned and removed irrelevant terms, clustered themes, built negative keyword maps, and validated everything through Google Ads PPC testing. This data-led approach ensured that only high-intent, relevant keywords formed the foundation of the SEO campaign.
The systematic keyword research resulted in a foundation of top-performing keywords with strong CTR, low CPC, and high intent. This comprehensive keyword framework consistently outperformed competitors, laying the groundwork for a successful and profitable SEO campaign for the credit union. The validated keyword list became the foundation of the credit union’s entire SEO campaign.
