# Technical SEO Consultant > Most SEO problems are technical at the root. Crawlability gaps, indexation failures, Core Web Vitals, and broken site architecture stop good content from ranking. I find them and fix them. Source: https://sunnypatel.co.uk/services/technical-seo-consultant/ Published by Sunny Patel, independent SEO consultant, Reading, Berkshire. Last updated 2026-09-05. ## Most SEO Problems Are Technical at the Root Content and links get most of the attention in SEO conversations. Technical SEO gets treated as a checklist, something to set up once and forget. That is a mistake, and it is the reason most business websites leave significant organic traffic on the table. Technical SEO is the foundation on which every other SEO effort depends. If Google cannot efficiently crawl and index your pages, content and links accomplish nothing. If your Core Web Vitals are poor, you are penalised in rankings. If your site architecture fragments link equity and signals, your strongest pages rank below their potential. If your schema markup is missing or incorrect, you are invisible in rich results that your competitors occupy. A technical SEO consultant diagnoses and resolves these infrastructure issues, the things no content writer or link builder can fix. Without this foundation, the rest of your SEO investment is at best inefficient and at worst completely wasted. I work with businesses that have plateaued in rankings despite good content, businesses recovering from Google algorithm updates, and businesses building new sites who want to get the technical architecture right from day one. **Initial consultations are free.** Every consultation includes a live review of your site's technical health and a specific assessment of the issues most likely to be holding you back.

Technical SEO covers the full infrastructure layer of how search engines discover, crawl, interpret, and index your website. Common issues, and the ones I regularly find even on well-maintained, large sites: ### Crawlability and Indexation Google can only rank pages it knows about. Crawl budget waste, disallowed pages, noindex tags applied incorrectly, canonical tags pointing to the wrong URLs, and robots.txt misconfiguration all prevent content from appearing in search results, even when that content is genuinely excellent. The audit process maps exactly which pages Google is crawling, which it is ignoring, and why. Fixing crawlability issues is often the fastest route to ranking improvement because it makes existing content visible again. ### Site Architecture and Internal Linking How pages link to each other determines how Google distributes authority across your site. Flat architectures, orphaned pages, crawl traps, and poor hub-and-spoke structures dilute link equity: meaning your most important commercial pages rank below their potential even when your overall site has strong authority. Structural fixes to internal linking and site architecture can produce significant ranking improvements without any new content or links. ### Core Web Vitals Google uses Core Web Vitals, Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and Interaction to Next Paint (INP), as ranking signals. Sites that fail these metrics are measurably disadvantaged in competitive searches. The causes are almost always technical: render-blocking resources, unoptimised images, layout instability from late-loading elements, and poor server response times. ### Schema Markup and Structured Data Schema markup helps Google understand what your pages contain and makes your results eligible for rich snippets: star ratings, FAQs, product pricing, and other SERP enhancements that dramatically increase click-through rates. Missing, incorrect, or incomplete schema is extremely common, even on professionally built sites. I implement full schema coverage using JSON-LD: LocalBusiness, Service, FAQPage, Article, BreadcrumbList, Person, and Organisation markup, correctly structured and validated. ### Duplicate Content and Canonicalisation Duplicate content, from URL parameter variations, session IDs, trailing slash inconsistencies, www/non-www splits, HTTP/HTTPS duplication, and CMS-generated URL variants, splits your ranking signals across multiple URLs instead of concentrating them on one. Canonicalisation resolves this and can produce immediate ranking improvements for pages previously fragmented across duplicates. ### Page Speed and Core Technical Performance Beyond Core Web Vitals, page speed affects user experience, crawl efficiency, and conversions. Render-blocking JavaScript, uncompressed images, missing caching headers, and poor hosting infrastructure are all fixable, and the improvements compound across every page on your site. ### International SEO and Hreflang For businesses targeting multiple countries or language variants, incorrect hreflang implementation causes serious indexation problems. Google serving the wrong language to the wrong market, duplicated indexation across regions, and hreflang return-tag errors are among the most technically complex issues I resolve. --- ## Why Hire an Independent Technical SEO Consultant? Technical SEO requires a rare combination: deep understanding of how search engines work at the crawler and algorithm level, combined with the ability to diagnose problems in code, server configuration, and CMS architecture. At a typical agency, the person writing your monthly report is rarely the person with this technical depth. Senior technical knowledge gets applied at the audit stage and then handed off to juniors for implementation. Errors get introduced. Issues get missed. As an independent technical SEO consultant, I do the analysis and the implementation oversight personally. When I identify a canonicalisation error or a crawl budget problem, I trace it to its root cause, not just flag it in a spreadsheet. And I work directly with your development team (or handle the implementation myself, depending on the issue) to ensure fixes are implemented correctly. ## What Does a Technical SEO Audit Include? A [technical SEO audit](https://sunnypatel.co.uk/services/technical-seo-audit/) is a comprehensive site health review covering: - **Crawl analysis**: mapping what Googlebot can and cannot access, identifying disallowed pages, noindex misuse, and crawl budget waste - **Indexation review**: comparing crawled pages against indexed pages, identifying gaps and causes - **Site architecture assessment**: evaluating URL structure, internal linking patterns, hub-and-spoke architecture, and orphan pages - **Core Web Vitals audit**: LCP, CLS, and INP performance across desktop and mobile, with specific root causes identified - **Schema markup review**: current implementation vs. recommended, missing schema types, validation errors - **Duplicate content and canonicalisation audit**: identifying all duplication sources and canonicalisation misconfigurations - **International SEO review** (if applicable): hreflang implementation, geo-targeting configuration - **Technical penalty assessment**: signs of algorithmic or manual action and recovery pathway - **Prioritised action plan**: every issue ranked by estimated impact, with implementation guidance Audits are delivered as structured reports with specific, actionable recommendations, not a checklist of warnings with no prioritisation. **Technical audit pricing:** from £495 for a focused audit to £1,200 for a comprehensive full-site review. All audits include a follow-up call to walk through findings and answer implementation questions.

[Technical SEO and on-page SEO](https://sunnypatel.co.uk/blog/technical-seo-vs-on-page-seo/) address different layers of the ranking problem: **Technical SEO** ensures Google can efficiently access, crawl, and index your pages. It is infrastructure, the foundation on which everything else sits. Without it, on-page optimisation and content quality cannot reach their potential. **On-page SEO** optimises the content and structure of individual pages: title tags, header hierarchy, keyword placement, semantic coverage, and internal link anchor text. It assumes the pages are crawlable and indexed, which is the technical layer's job to guarantee. Most sites need both. A technical audit identifies the infrastructure gaps; on-page optimisation then maximises the ranking potential of each page. The technical layer typically delivers faster initial improvements because it makes existing content visible rather than requiring new production. ## Which Platforms and Technologies Do You Work With? I work with businesses across all major platforms and site stacks: **WordPress**: the most common source of technical SEO issues due to plugin conflicts, misconfigured Yoast/RankMath settings, taxonomy and archive URL duplication, and render-blocking theme resources. I have deep experience diagnosing and resolving WordPress-specific technical SEO problems. **Shopify**: Shopify's default URL structure creates canonical challenges for product and collection pages. Faceted navigation, duplicate product URLs across collections, and theme-level performance issues require specific technical knowledge. **Woocommerce**: similar challenges to Shopify with additional complexity from WordPress plugin interactions and custom taxonomy URL structures. **Custom-built sites (Next.js, React, Vue, Laravel, etc.)**: JavaScript-rendered content, server-side vs. client-side rendering decisions, and custom CMS implementations each carry specific technical SEO implications I address directly with your development team. **Enterprise CMS platforms**: Sitecore, Contentful, Drupal, and other enterprise systems with complex URL patterns, multi-site architectures, and governance requirements. ## When Do You Need a Technical SEO Consultant? **Ranking plateau despite good content**: if you are producing strong content consistently but rankings have stalled, the bottleneck is almost always technical. Crawl budget waste, internal linking dilution, or canonicalisation issues are the most common culprits. **Post-migration ranking drops**: careful [SEO website migration](https://sunnypatel.co.uk/services/seo-migration-consultant/) planning prevents avoidable ranking losses. A URL structure change, CMS switch, or HTTPS migration without correct redirect implementation can lose years of accumulated authority in days. **Google algorithm update recovery**: if a core update, Helpful Content update, or spam update has reduced your organic traffic, a technical audit establishes whether an infrastructure issue is amplifying the impact and what the recovery pathway looks like. **New site build**: getting technical architecture right from the start, URL structure, canonical strategy, internal linking architecture, schema implementation, is significantly easier and cheaper than fixing it after launch. **Site acquisition**: before acquiring a site through an M&A process or buying an established domain, a technical audit identifies existing penalties, crawl issues, and architecture problems that affect the site's true value. **Ecommerce at scale**: large ecommerce sites with thousands of product and category URLs accumulate technical debt that suppresses ranking potential across the entire catalogue. Systematic technical resolution can produce significant indexation improvements. ## How We Work Together **Step 1: Free SEO diagnosis (20 minutes).** We focus on your biggest technical search problem, review the available evidence and identify the most useful next step, regardless of whether you engage further. **Step 2: Technical audit.** A comprehensive review (from £495 depending on site size) delivered as a structured report with prioritised recommendations. Includes a follow-up call to walk through findings with your team. **Step 3: Implementation and oversight.** Depending on your setup, I either work directly with your development team to implement fixes, or handle technical changes myself for simpler implementations. Monthly retainers (from £1,500) cover ongoing technical monitoring, architecture decisions, and implementation oversight. Technical SEO is not a one-time fix. Site changes, new content, and Google algorithm updates require ongoing technical monitoring to maintain and build on the improvements made.
