Technical SEO
Technical SEO to build a foundation search engines can crawl and understand
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.
Who this is a good fit for: Sites with indexing issues they can't explain · Teams migrating platform, domain or URL structure · Sites built on JavaScript frameworks (React and similar)
- 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.
Why it matters
What technical SEO is (and isn't)
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.
If left unresolved
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.

Process
How I approach technical SEO
Diagnosis prioritized by impact, not by error count
Request a Strategic SEO ReviewArchitectureStages
From URL to result: where access breaks
Selected stage
Crawl
robots, internal links, crawl budget
If this stage fails, this never happens: Render
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.

Questions
Frequently asked questions
- Is technical SEO the same as an SEO audit?
- No. Technical SEO is ongoing work on infrastructure, architecture and performance. The audit (SEO Audit service) is a point-in-time deliverable that documents the site's current state. Often an audit identifies the issues that technical work then resolves.
- Are all the errors a tool like Screaming Frog or Ahrefs flags equally urgent?
- No. Tools assign severity generically. A duplicate-heading warning on irrelevant pages matters far less than a crawl block on revenue-generating pages. Real prioritization is done by business impact, not by the tool's alert color.
- Are React or SPA sites at a disadvantage in SEO?
- They can be, if rendering isn't handled correctly. Google can execute JavaScript, but not always immediately or completely, and other crawlers are more limited still. You need to verify how critical content is served and decide whether server-side rendering, pre-rendering, or targeted fixes are needed.
- How long does it take to see results from a technical fix?
- It depends on the issue, site size, and how often Google crawls the site. Some indexing changes show up within weeks; architecture consolidation takes longer. I don't promise fixed timelines because they depend on factors outside my control.
- Do I need my developer involved in this work?
- Usually, yes. I diagnose, prioritize and specify the changes needed; implementation typically requires your development team, or mine working in coordination with you.
