Technical SEO consultant who spends more time in server logs than most people spend on social media. Founded Saravexinto in 2020 to document what actually moves rankings.
How technical audits became a fixation
Started building websites in 2011 when clients kept asking why their pages weren't ranking. Turned out most developers were ignoring everything that happened after the design phase.
Spent three years at a Johannesburg agency fixing sites that looked great but loaded like dial-up connections. Crawl budgets were being wasted on pagination nightmares. Structured data was an afterthought at best.
Saravexinto began as internal documentation that got shared more than expected. Now it's where technical implementations get tested in real scenarios rather than theoretical best practices.
Most SEO advice treats search engines like magic boxes. This site exists because algorithms have logic, servers have limitations, and understanding both makes the difference between ranking and hoping.
What gets covered here
Core Web Vitals optimisation that doesn't involve plugin recommendations. JavaScript rendering issues and how search bots actually process dynamic content. Structured data implementation that search engines can parse without throwing validation errors.
Server configuration details that affect crawl rates. Log file analysis that reveals what bots really do versus what analytics claims. International SEO setup for sites that need hreflang tags to actually work across regions.
Migration planning that preserves traffic through redirects that make sense. The articles assume you understand HTML and aren't afraid of a command line when server access is necessary.
Articles typically include command examples and configuration snippets.
No affiliate links to SEO tools or hosting providers.
Updates happen when search engines change behaviour, not on a content calendar.
Studied computer science at Wits but spent more time reverse-engineering how Google crawled student project sites than attending lectures. First client was a travel agency losing rankings after a redesign nobody tested for search impact.
Joined an agency in 2015 where every site audit revealed the same preventable mistakes. Developers building beautiful React applications with zero server-side rendering. Mobile sites that looked perfect but took 12 seconds to become interactive.
Left agency work in 2020 when it became clear most technical recommendations got ignored because clients wanted quick wins over infrastructure fixes. Saravexinto started as a place to document implementations that actually improved rankings when given time to work.
Current focus areas
Core Web Vitals optimisation beyond generic advice. JavaScript SEO for sites that can't be rebuilt as static pages. Server log analysis to understand what bots prioritise during crawls.
Why this matters
Too many sites lose rankings because developers don't think about crawl efficiency and SEO teams don't understand technical constraints. The gap between design expectations and search reality keeps widening.
