When people think about SEO, they often picture keyword research, content writing or link building. But without a strong technical foundation, those efforts can only go so far. An Advanced Technical SEO consultant ensures that your website’s infrastructure, speed, crawlability, and user experience align with what search engines expect - laying the groundwork for sustained rankings, traffic, and conversion growth.
Let's explore the technical areas many sites neglect, real data showing the impact of technical SEO, and how hiring an expert consultant can help. We’ll also link through to related topics so you can understand how this fits into the wider scope of SEO consulting services.
What “Advanced Technical SEO” Covers
Some of the key areas an advanced technical SEO consultant will audit or optimise include:
- Website speed & performance (including Core Web Vitals: LCP, FID / INP, CLS)
- Crawlability & indexability (robots.txt, sitemap, canonical tags, hreflang for international sites)
- Structured data & schema markup
- Redirects, URL structure, broken links
- Hosting, server response times, mobile optimisation
- Security (HTTPS), site architecture, clean code
- Accessibility WCAG compliance
Key Statistics That Show Why Technical SEO Matters
Here are recent stats from authoritative sources that underline why this investment delivers real value:
- Only 33% of websites meet all of Google’s Core Web Vitals thresholds. That means 67% have room for improvement in user experience metrics that Google uses. Amra and Elma LLC
- Over 70% of websites have slow page load issues. pageoptimizer.pro
- Sites with a good score on all three Core Web Vitals (LCP, FID/INP, CLS) are ~34% more likely to rank in the top 10 in Google SERPs. SQ Magazine
- Page speed impacts user behaviour significantly: users are much more likely to abandon pages that load slowly. E.g. more than 50% abandon if load time exceeds ~3 seconds. SEOPress
- Technical SEO fixes (schema markup, heading structure, alt text, link hygiene etc.) lead to measurable gains: a study across ~39,000 websites showed big improvements in impressions and visibility after making structural/technical improvements. Search Atlas
These statistics show that technical SEO issues are widespread - but also that fixing them often yields large returns.
How an Advanced Technical SEO Consultant Works
Here’s a typical process:
- Technical Audit & Diagnosis: Identify speed issues, broken links, redirect chains, duplicate content, schema gaps, mobile responsiveness, etc.
- Prioritisation & Roadmap: Decide which technical issues have the greatest impact (e.g. fixes for mobile performance or site architecture may be higher priority than cosmetic fixes).
- Implementation: Working with developers or using tools, make changes - e.g. optimising page load, implementing structured data, improving server configuration, compressing assets, ensuring mobile-first design.
- Monitoring & Iteration: After changes, monitoring through analytics, Google Search Console, Core Web Vitals reports, etc., to ensure improvements actually take hold.
- Integration with Other SEO Work: Ensuring content, local/international SEO, and ongoing site maintenance align with technical best practice.
How Advanced Technical SEO Consulting Links into Other Areas
To get full value from hiring a technical SEO consultant, it helps to see how this integrates with other consultative SEO roles:
- If you're using WordPress, a WordPress-SEO consultant will specifically ensure your theme, plugins, media, and hosting are tuned. (Related: see “Why a WordPress SEO Consultant Can Transform Your Website Performance.”)
- If your business operates locally, technical SEO consulting dovetails with local SEO consulting efforts - making sure service area pages, maps, and business profile pages load quickly, are indexed, etc.
- For businesses with an international audience, technical SEO fixes like correct hreflang implementation and server location / speed across geographies are crucial; this ties into international SEO consultant services.
What Results You Can Expect
When technical issues are addressed, businesses often see:
- Increased visibility in search results (more impressions, higher average positions)
- Reduced bounce rates, better engagement metrics (longer sessions, lower exits)
- More organic traffic, especially on mobile
- Higher conversion rates due to better UX & speed
- Improved user retention and brand trust
For example, the study of 39,486 sites (search atlas) showed strong gains in impressions and discoverability after technical fixes. Search Atlas
