Technical SEO & Site Audits
Your Site Ranks Page Three. But Should It Be Page One?
Most businesses think their SEO problem is content or backlinks. It’s not. It’s the 47 technical issues Google sees that you don’t. Crawl errors blocking 30% of your pages. Schema markup missing or broken. Mobile usability failures. Core Web Vitals in the red. Each one signals to search engines (and increasingly, to AI systems) that your site isn’t worth prioritising.
Technical SEO isn’t about gaming algorithms. It’s about removing the barriers preventing search engines and AI from understanding, trusting, and ranking your content. When ChatGPT or Perplexity decide which sources to cite, technical excellence matters. When Google decides which page deserves position one, clean architecture wins.
We audit your site’s technical foundation, identify what’s costing you visibility, and fix it.
Let us audit your site and we’ll show you what search engines actually see.

What Wonderful Technical SEO Looks Like
Default audits generate 200-line spreadsheets listing every minor issue with equal weight. You’re left wondering what actually matters and where to start. That’s not helpful.
Here’s what a wonderful technical SEO audit delivers:
- Critical problems blocking indexation ranked above cosmetic improvements (missing canonicals vs. missing alt text)
- Revenue impact estimates showing which fixes unlock the most visibility first
- Clear distinction between “fix immediately” and “optimise when you have time” issues
- Logical site structure search engines can navigate efficiently (not 47 orphaned pages with no internal links)
- XML sitemaps reflecting actual priority pages (not auto-generated lists of everything)
- Internal linking distributing authority to pages that drive revenue, not vanity URLs
- Structured data helping both traditional search and AI answer engines understand your content
- Organisation, product, service, FAQ, and review schemas implemented correctly (not abandoned half-finished)
- Rich snippet opportunities maximised so your listings stand out in search results
- Core Web Vitals meeting Google’s thresholds (LCP under 2.5s, INP under 200ms, CLS under 0.1)
- Mobile experience reflecting how 70% of your traffic actually uses your site
- Page speed maintained whilst preserving tracking, analytics, and conversion functionality

What Our Audits Always Uncover
- Crawl budget wasted on low-value pages whilst high-value content sits buried three clicks deep
- Schema markup implemented incorrectly so rich snippets never appear in search results
- Mobile experience failures blocking 70% of your traffic from engaging properly with your site
- Core Web Vitals in the red signalling to Google your site provides poor user experience
- Indexation issues preventing 30% of your content from appearing in search at all
The Cost of Waiting
Every month with technical SEO problems:
- Organic visibility declining as competitors with cleaner technical foundations outrank you
- AI answer engines citing competitors because your site’s structure makes content harder to understand
- Development resources wasted fixing symptoms instead of addressing root technical causes
- Content marketing investment undermined because technical barriers prevent discovery
- Revenue opportunities lost as high-intent keywords rank page two instead of page one
Default site audits give you spreadsheets. Proper technical SEO gives you rankings.
Don’t wait around expecting technical problems to fix themselves. Get in touch, let’s map where you are and where you need to go to get the most out of your technical SEO.

Technical SEO FAQs
How long does a technical SEO audit take?
A comprehensive technical audit takes 2-4 weeks depending on site size and complexity. Week one is the technical crawl and analysis. Week two is strategic recommendations and prioritisation. Weeks three and four involve implementation support and validation. We don’t rush audits – finding every critical issue matters more than delivering fast.
Smaller sites (under 500 pages) typically complete in 2-3 weeks. Larger ecommerce sites or complex multi-region websites may need the full 4 weeks to audit properly. We’ll clarify timeline during discovery based on your specific situation.
How much does a technical SEO audit cost?
Every site is different, so we provide exact pricing after understanding your specific requirements during discovery. Cost factors include site size (number of pages being crawled), technical complexity (headless setups, international sites, multi-language implementations), and whether you need implementation support or just strategic recommendations.
During our discovery call, we’ll assess your situation and provide transparent pricing tailored to your needs. No surprises, no hidden costs – just honest pricing based on the actual scope of work required for your technical SEO audit.
Can you help if we’ve already had an SEO audit?
Yes. Many businesses come to us with 200-line audit spreadsheets from other agencies but no clear path forward. We review previous audits, validate findings, and create an actionable implementation plan prioritised by business impact. Sometimes previous audits missed critical issues – we catch those too.
Often the problem isn’t the audit quality but the lack of implementation support. We don’t just identify problems – we help fix them or guide your team through technical changes. Our focus is getting issues resolved, not generating reports that sit unread.
Will you train our team?
Yes. Technical SEO audits include knowledge transfer so your team understands what drives search visibility. We explain findings in plain English, not just technical jargon. Recorded training sessions cover priority issues, implementation best practices, and ongoing monitoring strategies.
Training is tailored to your team’s technical expertise. Marketing teams get business-focused explanations of technical issues. Development teams get detailed technical specifications. Everyone gets actionable guidance they can apply immediately to maintain improvements.
Do you offer ongoing support?
Yes. After initial audit and implementation, many clients benefit from ongoing technical SEO monitoring and support. This includes quarterly audits catching new issues, Core Web Vitals monitoring, and rapid response when technical problems emerge. Ongoing support prevents technical debt accumulating again.
Some clients prefer project-based work (annual audits, migration support). Others benefit from monthly retainers for continuous monitoring. We adapt to what makes sense for your business and technical requirements. During discovery, we’ll discuss which approach fits your needs best.
Why choose Wonder for technical SEO audits?
We combine technical SEO expertise with development and analytics capabilities. This means audits consider how technical changes affect tracking accuracy, site performance, and conversion rates – not just search rankings. Our development team understands implementation complexity. Our analysts ensure measurement stays intact through technical changes.
Most SEO agencies identify problems but lack implementation capability. Most development agencies build well but miss SEO implications. We bridge both – finding issues and fixing them whilst preserving performance and measurement. This integrated approach prevents the common scenario where fixing SEO breaks something else.
What’s included in a technical SEO audit?
Technical audits include comprehensive site crawl analysis, Core Web Vitals assessment, mobile usability review, schema markup evaluation, indexation analysis, internal linking structure review, and robots.txt/sitemap optimisation. You receive prioritised findings ranked by business impact, detailed technical specifications for fixes, and implementation guidance.
We also assess how technical factors affect AI visibility – structured data helping answer engines understand content, crawl efficiency enabling better discovery, and semantic HTML improving content interpretation. Modern technical SEO considers both traditional search engines and emerging AI systems citing sources.
How do technical SEO and Core Web Vitals relate?
Core Web Vitals are Google’s specific performance metrics (LCP, INP, CLS) forming part of technical SEO. Technical audits include Core Web Vitals assessment because page speed affects rankings. However, technical SEO covers broader issues – crawlability, indexation, schema markup, mobile usability, and site architecture.
Some businesses need dedicated Core Web Vitals optimisation (comprehensive performance engineering). Others need broader technical SEO audits addressing multiple ranking factors. Often both are valuable – technical audit identifies all issues, then focused optimisation tackles performance specifically.
Can you audit international or multi-language sites?
Yes. International site audits address hreflang implementation, regional targeting configuration, and duplicate content across language versions. We ensure search engines understand which content serves which regions and languages. This prevents the common issue where UK content ranks in US searches or vice versa.
Multi-language sites require careful technical implementation to avoid duplicate content penalties whilst serving appropriate content to different audiences. Our audits verify hreflang tags, canonical URLs, and regional sitemaps work correctly. We also assess whether your international structure (subdirectories vs. subdomains) serves your SEO strategy effectively.
How do you prioritise audit findings?
We rank issues by business impact, not technical severity. A critical issue affecting 2% of pages ranks below a moderate issue affecting 60% of high-value pages. We estimate visibility and traffic impact for each recommendation so you invest resources where they’ll drive the most return.
Prioritisation considers implementation complexity too. Sometimes a high-impact issue is technically simple to fix – that becomes immediate priority. Other times a moderate-impact issue requires significant development resources – that might wait until you have capacity. We balance impact, effort, and your team’s capabilities when creating implementation plans.
What tools do you use for technical SEO audits?
We use Screaming Frog for comprehensive site crawls, Google Search Console for indexation and performance data, PageSpeed Insights for Core Web Vitals assessment, and various schema validators for structured data verification. Manual testing covers aspects automated tools miss – actual user experience, content quality, and strategic value.
Tools identify technical issues. Human expertise determines which issues actually matter for your business. We don’t generate automated reports – we analyse findings, prioritise by impact, and create actionable implementation plans tailored to your specific situation and technical capabilities.
How does technical SEO affect AI visibility?
AI answer engines (ChatGPT, Perplexity, Claude) increasingly cite web sources when answering queries. Clean technical foundations help these systems understand, trust, and reference your content. Structured data (schema markup) provides explicit context about content meaning. Semantic HTML clarifies content hierarchy and relationships.
Technical excellence signals authority to AI systems just as it signals quality to traditional search engines. Sites with poor technical foundations struggle to get cited by AI because systems can’t efficiently crawl, understand, or trust the content. As AI-powered search evolves, technical SEO becomes even more critical for visibility.
Can you help with algorithm updates?
Yes. When Google releases algorithm updates, we assess impact on your rankings and identify technical factors contributing to visibility changes. Most algorithm updates reward sites with strong technical foundations – good Core Web Vitals, clean architecture, proper mobile optimisation. Sites with technical debt often see rankings decline after updates.
We help businesses recover from algorithm penalties by addressing root technical causes, not just symptoms. If an update targeted page experience, we optimise Core Web Vitals. If it emphasised mobile usability, we fix responsive design issues. Our focus is building technical resilience so future updates help rather than hurt your rankings.
What’s the difference between technical SEO and accessibility?
Technical SEO optimises for search engine crawlers. Accessibility optimises for all users, including those with disabilities. However, the two overlap significantly – semantic HTML, proper heading hierarchy, descriptive alt text, and keyboard navigation benefit both search engines and users with accessibility needs.
Many technical SEO improvements enhance accessibility automatically. Clean site structure helps screen readers navigate content. Fast page loads benefit users with cognitive disabilities. Mobile optimisation supports users with motor impairments. We consider both when auditing because inclusive design improves SEO whilst expanding your addressable audience.
How do you handle ecommerce technical SEO?
Ecommerce sites have specific technical challenges – thousands of product pages, faceted navigation creating duplicate content, stock status affecting indexation, and structured data for products and reviews. Our audits address these ecommerce-specific issues alongside standard technical SEO factors.
We ensure product schema markup appears correctly in search results, category pages don’t compete with products for rankings, and out-of-stock items are handled appropriately. Ecommerce audits also cover checkout page optimisation (though conversion issues fall under CRO), page speed for product pages, and mobile commerce usability.
What happens after audit implementation?
After implementing priority fixes, search visibility typically improves within 4-8 weeks as Google recrawls and re-evaluates your site. We monitor rankings, organic traffic, and Core Web Vitals to validate improvements. Some fixes show immediate impact (correcting noindex tags). Others take time (building authority through improved internal linking).
Most businesses benefit from quarterly technical reviews catching new issues before they accumulate. Regular monitoring ensures technical improvements stick and new content launches with proper optimisation. Some clients handle ongoing monitoring internally using our documentation and training. Others prefer our continued support through retainers.
