    Technical SEO to build a foundation search engines can crawl and understand

    The foundation before the tactics

    Technical SEO isn't a dump of tool errors. It's the infrastructure that decides whether your content gets crawled, indexed and shown correctly in the first place. I work on architecture, performance and how search engines actually process your site, prioritizing what affects the business, not what a scanner flags as "critical."

    An initial conversation to understand your business and its search opportunities.

    In summary

    What you need to know before continuing

    • Crawling & indexing What Google can actually crawl, what gets indexed, and why pages fall out.

    • Architecture & JavaScript Internal linking structure and rendering behavior on React/SPA-style sites.

    • Performance & Core Web Vitals How load speed and page experience factor into how your site is evaluated.

    • Impact-based prioritization Not all technical errors carry the same weight — priority is set by business impact, not tool severity scores.

    Definition

    What technical SEO is (and isn't)

    Technical SEO is the set of infrastructure, code and architecture decisions that determine whether a search engine can access your content, understand it, and consider it eligible to rank. It's not just fixing whatever a crawler flags — it's understanding how those issues affect discovery, indexing and real user experience.

    Why it comes before content or links

    If Google can't crawl a section, it doesn't get indexed. If it isn't indexed, it doesn't compete for anything, no matter how good the content is. Technical issues cap the ceiling on everything else you invest in SEO.

    What happens if it's ignored

    Important pages left out of the index, crawl budget wasted on irrelevant URLs, duplicate content competing with itself, and slow experiences that hurt both users and how the site gets evaluated.

    ⚠️ Common problems

    Technical issues I work with most often

    Each with a different effect on visibility — not just a line in a report

    Inconsistent crawling & indexing

    Relevant pages Google doesn't crawl, only partially indexes, or excludes due to conflicting robots.txt, sitemap or noindex signals.

    Impact:Content that's invisible even when it's well written.

    Disorganized site architecture

    Internal linking hierarchies that dilute the authority of important pages or bury key content too many clicks deep.

    Impact:Priority pages competing at a disadvantage against secondary ones.

    Canonicalization & duplicate content

    Parameterized URLs, filter variants or desktop/mobile versions that create duplication and confuse which version should rank.

    Impact:Relevance signals split across multiple URLs instead of consolidated.

    Rendering on JavaScript / SPA sites

    Content that relies on client-side JavaScript and doesn't render reliably for crawlers, especially on React-based frameworks.

    Impact:Content and links users see that search engines don't process the same way.

    Performance & Core Web Vitals

    Load times, visual stability and interactivity below expectations, affecting both experience and quality signals.

    Impact:Friction for users and one more variable in how the site gets evaluated.

    Missing or broken structured data

    Incomplete schema.org markup, implementation errors, or markup misaligned with the page's visible content.

    Impact:Fewer rich-result opportunities and weaker context signals.

    Poorly planned migrations & redesigns

    Domain, platform or URL-structure changes without a redirect plan and post-launch validation.

    Impact:Months of accumulated visibility and indexing lost.

    International technical implementation

    Hreflang tags that are misconfigured or inconsistent across language or country versions.

    Impact:Google serving the wrong version to the wrong market.
    🎯 Structured process

    How I approach technical SEO

    Diagnosis prioritized by impact, not by error count

    01

    Crawl & indexing review

    How Google accesses the site today: what it crawls, what it indexes, and where crawl budget is being wasted.

    02

    Architecture & rendering assessment

    Internal linking structure and how the site actually behaves for crawlers, including JavaScript/SPA-specific considerations.

    03

    Business-impact prioritization

    Not every technical finding carries the same weight. Findings are ranked by real effect on visibility and revenue, not by the severity level a tool assigns.

    04

    Implementation plan

    Concrete, actionable recommendations for your development team, with clear validation criteria after each change.
