How to improve SEO 2019

By 2019, SEO had matured beyond quick wins and keyword stuffing. The focus shifted entirely to what Google called "E-A-T" — expertise, authoritativeness, and trustworthiness — particularly after the March 2019 core update that hit many sites hard. For your clients, this meant conducting a content audit to identify thin, low-value pages that weren't demonstrating real expertise. You needed to either substantially expand these pages with detailed information backed by credentials, or consolidate them. For client sites in YMYL categories (Your Money or Your Life — finance, health, legal), this became critical. Building author bios with credentials, linking to published work, and establishing clear site authority on specific topics became standard practice rather than optional.

Technical SEO remained foundational but evolved toward Core Web Vitals precursors and mobile-first indexing implementation. Google had fully shifted to mobile-first indexing, so any client still primarily optimizing for desktop was already losing ground. You needed to audit mobile performance comprehensively — not just checking mobile usability in Search Console, but actually testing page speed, ensuring touch elements weren't cramped, and verifying that all desktop functionality worked on mobile. Site speed was increasingly important, though not yet the massive ranking factor it would become later. Focus on fixing render-blocking resources, optimizing images properly, and implementing lazy loading.

Backlink quality mattered far more than quantity by 2019, and you should have been actively managing link profiles to remove spammy or irrelevant links. The manual link-building strategy shifted toward content-driven outreach — creating genuinely valuable content that earned links naturally rather than pursuing guest posts on unrelated sites. For local SEO, Google My Business optimization became even more critical, with citation consistency and review generation directly influencing local pack rankings.

Structuring content strategically around topic clusters rather than individual keyword targets was also gaining traction. Instead of writing single articles targeting one keyword, you'd create comprehensive pillar content on broad topics with supporting cluster content linking back, which both improved user experience and signaled topical authority to Google.
