This episode brings together Karl from Searcharoo and semantic SEO expert Luis Salazar Jurado because the goal is to bridge developer thinking with high level SEO strategy. Luis shares how starting as a PHP developer shaped his entire approach to SEO because a programmer’s mindset forces him to solve problems systematically, think in templates, and treat websites like living systems rather than static pages.

The conversation dives into technical SEO, semantic SEO, and large scale site migrations because many eCommerce sites are one bad rebuild away from a traffic collapse. They break down how to handle 10,000+ URL changes, why you should never change theme, architecture, and URL structure all at once, and how to use redirects, crawl budget and link building to protect rankings. Luis explains ranking states, server log analysis, JavaScript bloat, and why structured data should load early because saving Google time directly improves how fast a site recovers and grows.

They explore topical authority, entity relationships and product attributes at scale because semantic SEO thrives on complete, precise information rather than thin category pages. Brand signals, PPC data and user signals are framed as the real north star for SEO strategy because traffic without conversion is pointless. Luis also explains how he keeps clients for 5–9 years by thinking like a business partner, not a report writer, because proactive strategy and honest communication outlast vanity PDFs and short term tactics.

Listeners who care about migrations, large eCommerce builds, semantic SEO and long term client retention will get a brutally practical masterclass because this episode stays in the trenches from start to finish.
