What an SEO developer does
An SEO developer combines technical web development with SEO marketing to make your site visible, fast, and easy for search engines to index. They focus on crawling, site architecture, page performance, structured data, and implementing on-page changes that support your content and keyword strategy.
Practical ways they improve rankings
- Technical audits: identify crawl errors, broken links, redirect chains, indexation issues, and server-side problems that prevent search engines from ranking pages.
- Performance optimization: reduce page load times through image optimization, caching, critical CSS, and efficient JavaScript to improve Core Web Vitals and user experience.
- Structured data & metadata: implement schema markup, title tags, and meta descriptions so search engines understand content and display richer snippets in search results.
- Mobile and accessibility fixes: ensure responsive design, touch-friendly controls, and semantic HTML that boost mobile rankings and usability.
- On-page collaboration: work with content and marketing teams to align keywords, internal linking, and content structure for conversion-focused traffic.
- Tracking and testing: set up analytics, run A/B tests, and measure organic traffic and conversion changes from technical improvements.
Hire an SEO developer when you have indexation or speed issues, a large site to scale, or when SEO changes require code updates. Start with an audit, prioritize fixes that affect traffic and conversions, and expect iterative improvements rather than overnight jumps in rankings.
