SEO Developer
Bridges the gap between SEO strategy and code implementation by building the technical foundations that help search engines crawl, render, and rank a website more effectively.
If you treat an SEO developer as a content writer or a general web developer, you miss the code-level execution that makes technical fixes actually ship.
Key points
- An SEO developer writes code, not content — their work affects crawlability, rendering, and performance.
- They translate SEO requirements into production code, bridging the gap between strategy and engineering.
- Common tasks include implementing redirects, canonical tags, structured data, and sitemaps.
- Technical SEO is ongoing maintenance, not a one-time fix — frameworks and search guidance evolve.
A React site that disappeared from search
A news site rebuilt with React relied entirely on client-side rendering. Googlebot could not render the content, and indexed pages dropped from 20,000 to 5,000 within three months. The SEO developer implemented dynamic rendering using Prerender.io, configuring the server to serve pre-rendered HTML to Googlebot. Within six weeks, indexation recovered to 18,000 pages, and organic traffic returned to 85% of its previous level.
Three common mistakes about SEO developers
- Treating as content SEO An SEO developer focuses on code, not keywords, unlike an organic seo specialist. Expecting content writing misses the technical implementation that ships fixes.
- Confusing with general web dev A general web developer may not know about technology in seo or structured data. An SEO developer adds SEO responsibility to their coding skills.
- Assuming one-time fixes Technical SEO changes need maintenance as frameworks evolve. Following seo tips from Reddit can help, but verify against current documentation.
Three tasks an SEO developer handles daily
- Improving crawlability They configure robots.txt directives, generate XML sitemaps, and optimise internal linking to help search engines discover pages efficiently while avoiding low-value crawl paths.
- Implementing structured data They add schema markup for rich results, such as articles, products, and reviews, following Google Search Central documentation to enable eligible features.
- Optimising Core Web Vitals They work on page speed, responsiveness, and visual stability to meet Google's Core Web Vitals thresholds and improve user experience.
