The technical foundation decides your rankings
Without clean technology, even the best content cannot rank. Technical SEO lays the foundation for lasting visibility, in Google and more and more in AI systems such as ChatGPT, Perplexity and Claude. A full SEO audit uncovers every technical weak spot.
Traffic
More traffic after tech fixes
Once crawl errors, redirect chains and slow pages are fixed, Google can capture all of your content. That creates the basis for more organic traffic.

Crawlability & indexing
We make sure Google and AI crawlers (GPTBot, PerplexityBot) find and index all your important pages. Robots.txt, XML sitemaps, canonical tags: the technical basis for visibility in search engines and LLMs. During an SEO relaunch, we check these points before and after go-live.

- Rich snippet optimization
- Knowledge Graph integration
Site architecture & page structure
Flat hierarchy, clean URLs, strategic internal linking: for good crawlability and clear navigation for users. Combined with on-page optimization, this gives your rankings the best possible basis.

Who benefits from technical SEO?
Technical SEO pays off for every company with an online presence. These industries benefit in particular:
E-commerce & online shops
Technical errors cost revenue. An audit uncovers crawl problems, duplicate content and lost ranking opportunities.
Healthcare & pharma
In regulated industries, trustworthiness counts. An audit strengthens E-E-A-T signals and technical quality.
B2B & SaaS
Complex buyer journeys need a solid content strategy. The audit shows where you lose leads.
Finance & insurance
High CPCs make organic visibility especially valuable. An audit finds the most efficient ranking opportunities.
Real estate
Local and national visibility are equally important. The audit optimizes both systematically.
Trades & service providers
Many tradespeople's websites have basic technical problems. An audit creates the basis for local rankings.

Our technical SEO analysis uncovers every problem: crawl errors, slow loading times, missing schema markup, duplicate content and more, and fixes them systematically.
The result: faster indexing, better Core Web Vitals and a website that Google and AI crawlers can read without friction.

More than ever.
AI search engines such as ChatGPT, Gemini and Perplexity use the web as their source. Without strong SEO, there is no GEO. SEO is the foundation, GEO builds on it.

Maximum visibility
Google rankings + AI citations = more qualified traffic from all channels.

If you combine both, you are found on Google and can be named as an expert in AI answers. Technical SEO is a matter of trust — at SEOX, Baris Gündogdu, SEO expert, an experienced SEO & GEO specialist, stands behind it.
Frequently asked questions about technical SEO
What is technical SEO?
Technical SEO covers all technical optimizations that make sure search engines can crawl, understand and index your website efficiently. This includes page speed, crawlability, indexing, structured data, HTTPS, hreflang and more.
Why do Core Web Vitals matter for SEO?
Core Web Vitals (LCP, INP, CLS) have been an official Google ranking factor since 2021. Fast, stable pages rank better and have lower bounce rates. Google measures the user experience directly.
How long does it take to fix technical SEO problems?
Quick wins such as missing meta tags or canonical errors can be fixed within days. Larger projects such as page speed optimization or changes to the site architecture take 2-8 weeks.
Which tools does SEOX use for technical SEO?
We use a combination of Google Search Console, Screaming Frog, Ahrefs, PageSpeed Insights, Chrome DevTools and our own analysis scripts. For Core Web Vitals, we use CrUX data and lab data.
Do I need technical SEO if I use a CMS like WordPress?
Yes. WordPress and other CMSs in particular often have technical problems: slow plugins, missing schema markup, duplicate content, unoptimized images. A technical SEO audit uncovers these problems systematically. Our specialized WordPress SEO services fix them for the long term.
Why does technical SEO matter for GEO & LLMO?
AI crawlers and large language models need technically clean websites to index content correctly and use it in their answers.
Crawl
Crawlability for AI systems
LLM crawlers such as GPTBot and PerplexityBot need clean page structures, fast loading times and a correct robots.txt configuration to index efficiently.
JSON-LD
Schema markup as the language of AI
Structured data in JSON-LD translates your content into a machine-readable format that AI systems can process directly and include in their answers.
Core Web
Performance as a ranking signal
Both Google and AI platforms prefer technically optimized websites. Fast, error-free pages are used as a source more often.
