SEO focused on topical authority through strategic internal linking, long-tail keyword targeting, and technical improvements to site speed and crawlability.

Organic traffic increased 287% (45K to 174K monthly visitors). Daily impressions grew 457% (28K to 156K). Ranking for 8,400+ keywords with 1,200+ in top 3 positions. CTR improved from 2.1% to 3.8%. Average position rose from 18.4 to 6.2. Search visibility jumped from 34% to 78%. Newsletter subscribers grew to 109,000+. Page load times improved 64%, reducing bounce rate by 41%.
