What does a tech SEO agency do?
Your website could be making it harder for search engines and AI tools to crawl, understand, and rank your content. We audit your technical foundations, fix what is broken, and remove what is holding performance back.
This includes:
- Crawlability and indexing
- Site architecture and internal linking
- JavaScript rendering
- Log file analysis
- XML sitemaps
- Canonicalisation, structure data, hreflang
- Redirects, page errors and migrations
- Core Web Vitals and speed performance
At Rayze, our trusted tech SEO managers and developers help ambitious businesses become the answer on Google and AI search by building the technical foundations they rely on.
Crawl, render, rank.
Why tech SEO matters for your search performance
Rising bounce rates
Core Web Vitals affect both rankings and conversions. Slow load times frustrate users — research suggests bounce rates can rise by 32% when load time increases from one second to three. That directly affects engagement and revenue.
Loss of organic traffic
A poorly optimised site appears less often in search rankings and AI results. If organic is your primary channel, JavaScript rendering failures alone can have a measurable impact on visits and leads.
Revenue lost to competitors
A well-optimised website does not just bring traffic — it brings the right kind of traffic. Weak technical foundations make it easier for competitors to outrank you and capture demand that should be yours.
Reduced visibility in AI search
AI tools are more likely to mention brands they can clearly understand and trust. Technical SEO helps make that possible. That includes clean site structure, schema, and the signals AI tools rely on to interpret your content.
Crawl and indexation issues
Botched migrations, orphaned pages, even content bloat, stop search engines from crawling and indexing your content properly.
Rayze's technical SEO services
We build a solid technical SEO foundation to help you get found by the right people in the places that matter.
Technical SEO Audit
A full diagnosis of your site's crawlability, indexing, rendering, speed, architecture, and structured data — delivered as a priority-based roadmap, not a checkbox exercise. We focus on what matters based on how your site is actually built.
Site Speed Improvement
Slow pages cost you rankings and users. We diagnose, fix, and monitor Core Web Vitals — Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS) — to keep your site fast and your bounce rates low.
Rendering Repair
We test how Google renders your JavaScript frameworks — React, Angular, Vue — and identify the pages it is failing to process correctly. What Google cannot render, it cannot rank.
Log File Analysis
We track how Googlebot moves through your site and identify crawl waste, indexation gaps, and priority issues that are limiting your visibility across Google and AI search.
Structured Data & Schema
We implement and validate schema that helps search engines and AI tools correctly interpret your products, content, and brand — so you appear in the right results, described in the right way.
An extension to your team
When your in-house team needs an extra pair of senior hands, we step in — whether that means guiding implementation, reviewing technical decisions, or taking the work on directly. We adapt to how your team works.
How much does a tech SEO agency cost?
1. One-time technical audits usually cost between £3,000 and £10,000 based on the size and complexity of the website.
2. Website migrations are priced usually between £5,000 and £30,000, depending on the size of the website.
3. Monthly Technical SEO Retainers cost between £2,500 per month and £12,000 per month.
The pricing depends on variables like site size, CMS complexity, number of languages, development access, and reporting cadence. Once we implement fixes, most sites begin to show movement within four to twelve weeks, with results compounding over three to six months.

FAQs
Frequent questions we receive around technical SEO optimisation.
Is technical SEO a one-off project or ongoing?
Both. At Rayze, you can purchase a one-off tech SEO project with us, where we’ll diagnose your site, audit and make the improvements with our developers. If you’re a retainer, we start our partnership with a website audits to fully clean and optimise your site. We continue with monthly maintenance checks and minor fixes as most sites benefit from ongoing monitoring.

Early wins are visible within 8-12 weeks, compounding over 3-6 months. However, results can be impacted or delayed by external factors such as Google Core Updates.
