A fast, stable website is the foundation of SEO
Great content cannot rank if your platform is slow, malfunctioning or difficult for search engines to crawl. Google treats page experience and Core Web Vitals as ranking inputs, so poor technical health can drag down visibility even when content is strong.
Our engineers focus on:
- Core Web Vitals and page speed
- Crawlability, indexation and internal linking
- Stability across releases and deployments
- Security and compliance for regulated teams
The result is a platform that supports sustainable traffic and conversion uplift, not one that quietly erodes it.
When to call Growcreate
Our technical SEO services are designed for teams who recognise that something is wrong but do not have the capacity or skills to trace it through a complex stack.
Typical triggers include:
- Rankings or organic traffic have dropped after a redesign, migration or series of deployments
- Core Web Vitals and page speed scores are holding back performance in the UK or key markets
- Crawl errors, duplication or indexation issues are piling up in Console
- Your Umbraco or Optimizely platform has accumulated technical SEO debt and small fixes no longer move the needle
- A previous agency has delivered a report but your team is struggling to implement the recommendations
In each case, the goal is the same – stabilise the platform, improve visibility and recover conversions as quickly as possible.
What a technical SEO audit includes and prioritises
Many people for what a technical SEO audit includes and prioritises. At Growcreate, the audit is a structured engineering exercise, not a one-size checklist.
Every engagement starts with a full technical audit with priorities that covers:
You receive a prioritised roadmap broken into quick wins, medium-effort changes and strategic items, all framed as implementation and dev-ready tickets for your team or ours.
Mobile and responsive optimisation
- Responsive behaviour across and devices
- Mobile-specific performance bottlenecks such as heavy images or scripts
- Tap targets, font legibility and layout shifts on touch devices
Outcome – mobile visitors experience fast, stable pages, which supports mobile-first indexing and higher engagement.
Site architecture and templates
- URL structure, navigation depth and internal linking for key journeys
- Template, component and schema usage across content types
- Pagination, filters and parameters that can dilute authority
Outcome – a structure that concentrates authority on priority pages and makes navigation clearer for users and crawlers.
Core web vitals and page speed
- Real-user and lab data for LCP, INP/FID and CLS
- Breakdown by template, device, geography and user type
- Focused recommendations for code, images, scripts and infrastructure
Google’s Core Web Vitals benchmark fast loading, interactivity and visual stability. For example, guidance recommends LCP under 2.5 seconds, FID or interaction under 100 ms and CLS under 0.1 for a good experience (Source: Wikipedia, Source: Positional).
Outcome – a clear picture of which templates or features hurt experience and ranking potential, and a path to bring them within target thresholds.
Crawlability and indexation
- Log and crawl analysis to see how engines actually move through your site
- XML sitemaps, robots.txt, canonical tags and hreflang where relevant
- Identification of orphaned pages, crawl traps, duplication and soft 404s
Outcome – engines can discover, understand and index the right pages, improving visibility without extra content.
Platform, hosting and security
- .NET, Umbraco or Optimizely versioning and support status
- Azure or hosting configuration, caching and CDN usage
- SSL, HTTP security headers and known vulnerabilities
Outcome – a secure, performant foundation that keeps engines and security teams comfortable.
Analytics, tracking and data quality
- Correct deployment of analytics tags and consent controls
- Event and goal tracking for key conversions
- Baseline metrics to measure before and after improvements
Outcome – you can see where technical SEO work creates traffic and conversion uplift.
From audit to implementation
A common question is whether an agency can implement technical SEO fixes or only audit. Growcreate is an engineering-first partner, so we stay involved until changes are live and validated.
Depending on your needs, we can:
- Implement fixes directly in your Umbraco, Optimizely or headless codebase
- Supply dev-ready tickets, pull requests or configuration changes for your internal team
- Pair with your engineers to agree patterns and standards for future work
- Validate changes in staging and production with automated and manual tests
Because our team already runs Azure DevOps, performance optimisation and 24/7 support for .NET platforms, we work comfortably inside CI/CD pipelines on Azure DevOps, GitHub or similar tooling (Source: Growcreate, Source: Growcreate).
This approach reduces hand-off friction, cuts deployment risk and ensures technical SEO recommendations actually land in your platform, rather than sitting in a report.
How we improve core web vitals and page speed in the UK
If you are looking for how to improve Core Web Vitals and page speed in the UK, we focus on real outcomes rather than chasing synthetic scores.
Typical work includes:
- Image optimisation – modern formats, compression, lazy loading and responsive image sets
- Script optimisation – reducing render-blocking JavaScript, deferring non-critical scripts and code splitting
- Server and CDN tuning – caching, HTTP/2 or HTTP/3, and edge configuration for UK and key regions
- .NET and CMS upgrades – aligning Umbraco and Optimizely with supported .NET versions for faster runtimes (Source: Growcreate)
- Layout stability – reserving space for late-loading components, fonts and media to improve CLS
Independent studies show that slow websites lose both rankings and revenue. by multiple providers reports that over half of mobile users abandon pages taking more than three seconds to load, and each additional second of delay can reduce conversions by around 7 percent (Source: Think with Google).
By improving Core Web Vitals and page speed, we help you protect organic visibility and more of that traffic into enquiries, sales or sign-ups.

DevOps and deployment integration
Technical SEO often fails in complex organisations because recommendations collide with release cycles, compliance checks or legacy deployment patterns.
Growcreate embeds DevOps and deployment integration into every engagement:
- Work is broken into tickets aligned to your sprint cadence
- Changes move through staging, UAT and production using your release process
- Performance, uptime and SEO metrics are monitored before and after each deployment
For teams already running CI/CD on Azure or Umbraco Cloud, we design technical SEO improvements that fit into existing pipelines, including zero-downtime release patterns where required (Source: Growcreate).
This means fewer surprises in production and a safer path from technical SEO insight to live change.
Measurable outcomes from technical SEO
Technical SEO is only valuable if it produces clear business results. We align every engagement with metrics that matter.
| Outcome | What We Change | How We Measure |
|---|---|---|
| Traffic and conversion uplift | Crawlability, internal linking, Core Web Vitals, UX defects | Organic sessions, goal completions, revenue |
| Better Core Web Vitals | Images, scripts, infrastructure and templates | LCP, INP/FID, CLS across key templates |
| Improved crawl efficiency | Sitemaps, robots, parameters, duplication | Indexed pages, crawl stats, log files |

Technical SEO FAQs
Our audit covers crawlability, indexation, architecture, Core Web Vitals, mobile optimisation, platform configuration, security and analytics. We score each issue by impact, effort and risk, then build a roadmap of quick wins, medium-term improvements and strategic changes. You receive a full technical audit with priorities plus implementation and dev-ready tickets.
We do both. Many clients ask us to work directly in their Umbraco, Optimizely or headless codebase, integrating with existing DevOps workflows. Others prefer us to provide tickets and technical guidance for their in-house teams. In either case, we stay involved through testing and validation.
Technical SEO helps engines crawl and index more of the right content, improves page experience signals like Core Web Vitals and stabilises performance across devices. This makes it easier to rank, keeps visitors on-site longer and reduces friction in key journeys, which together support higher organic traffic and better conversion rates (Source: Positional, Source: SEO University).
No. While we are known for Umbraco and are an Umbraco Platinum Partner, we also work extensively with Optimizely, custom .NET platforms and headless CMS architectures. The common thread is complex, high-risk platforms where technical SEO and engineering need to move together.
Most teams benefit from a full audit at least once a year, plus a focused around major releases, migrations or redesigns. For fast-moving or regulated environments, we can build technical SEO checks into your quarterly planning.
Yes. We regularly provide the engineering and technical SEO layer while another agency leads content, campaigns or digital strategy. Our role is to expose and fix platform issues that hold their work back.
