Most developers build sites that look good but don't rank. Most SEO people get traffic to pages that don't convert. I've been doing both for 10 years because that's the only way sites actually make money. 𝗛𝗲𝗿𝗲'𝘀 𝘄𝗵𝗮𝘁 𝘁𝗵𝗮𝘁 𝗮𝗰𝘁𝘂𝗮𝗹𝗹𝘆 𝗹𝗼𝗼𝗸𝘀 𝗹𝗶𝗸𝗲: When I build a Website, I'm already thinking about Core Web Vitals, schema markup, and how Google will crawl it. When I optimize for SEO, I can fix the technical problems myself instead of sending you back to your developer. You get a site that loads in under 2 seconds AND ranks for keywords your competitors miss. You get conversion-focused pages that actually show up in search results. ━━━━━━━━━━━━━━━━━━━━ 𝗧𝗵𝗲 𝘄𝗼𝗿𝗸 𝗜 𝗱𝗼 𝗯𝗿𝗲𝗮𝗸𝘀 𝗱𝗼𝘄𝗻 𝗶𝗻𝘁𝗼 𝘁𝗵𝗿𝗲𝗲 𝗽𝗮𝗿𝘁𝘀: 𝟭.

I cut load time from 5.2 seconds to 1.8 seconds and restructured their pages for search intent. Trial signups jumped 47% in three months. ✓ An e-commerce site needed both development work and SEO. I rebuilt their product pages, fixed mobile issues, and ranked them page 1 for 12 high-intent keywords. Organic revenue grew 340% over 8 months. ✓ A finance company wanted speed and trust. I redesigned their site, achieved an 89 PageSpeed score, and optimized their conversion funnel.
