Bitsler JavaScript, React and indexation SEO
Bitsler was one of my most technically demanding iGaming assignments, with a platform heavily reliant on JavaScript and React and a range of difficult crawling, rendering and indexation problems.
Head of SEO
As Head of SEO for an international crypto casino and sportsbook, my focus was heavily technical: React and JavaScript SEO, rendering, crawl and indexation, Search Console diagnostics, architecture, canonicals, schema and expansion into the US market.
The SEO challenge
The central challenge was not simply whether pages contained the right metadata. It was understanding why important URLs were failing to enter or remain in Google’s index and how client/server rendering behaviour affected what Google could access.
What I worked on
JavaScript rendering
React SEO, client/server behaviour and rendered output
Googlebot accessibility
Understanding what search crawlers could actually retrieve
Indexation diagnostics
Search Console anomalies, canonicalisation and duplicate URLs
Crawl paths
Internal linking, discovery and site architecture
Schema & metadata
Structured data and scalable on-page signals
Engineering delivery
Direct collaboration with developers and validation after deployment
Results and impact
The project strengthened my approach to difficult technical SEO investigations: reverse-engineer the system-level cause, translate it into engineering requirements and validate the implementation after release.
This was hands-on Head of SEO work in a technically complex international gambling environment.
