The Foundation
Everything Else Depends On.
Only around 40 percent of websites currently pass Google's Core Web Vitals thresholds. Most of the rest are losing rankings to competitors with weaker content but stronger technical foundations. Technical SEO is what decides whether your content ever gets the chance to compete at all.
The 2026 Reality
Technical SEO Is No Longer
Just About Google.
Why This Matters More Than Ever
AI Crawlers Do Not
Execute JavaScript.
This single fact has changed technical SEO more than any algorithm update in recent years. Googlebot can render JavaScript, slowly and imperfectly, but most AI crawlers cannot. If your critical content only appears after JavaScript executes, it is effectively invisible to ChatGPT, Perplexity, Claude, and the AI systems that increasingly sit between your business and its buyers.
For a business investing in content and authority, this creates a scenario where everything looks fine in a traditional rank tracker while an entire discovery channel silently excludes you. Your rendering strategy stopped being a developer preference and became a direct business decision about visibility.
Here is what technical debt actually costs a business, month after month:
- ✕Content invisible to AI search engines because it depends on client side rendering to appear
- ✕Ranking signals split across duplicate URLs by conflicting canonical tags, diluting the authority you have already earned
- ✕Failing INP scores caused by heavy JavaScript bundles and third party scripts, measurably disadvantaging you in competitive results
- ✕Crawl budget wasted on low value URLs, parameters, and duplicates instead of the pages that actually drive revenue
- ✕Structured data errors costing eligibility for rich results that can substantially increase click through rate
- ✕AI crawlers like GPTBot, ClaudeBot, and PerplexityBot blocked in robots.txt by accident, forfeiting AI citations entirely
What's Included
Nothing Is Built on a
Damaged Foundation.
Core Web Vitals
Interaction to Next Paint replaced First Input Delay as a Core Web Vital, and it is now the most commonly failed metric because it measures responsiveness across the entire user session, not just initial load.
What we target
- LCP under 2.5 seconds through image preloading and server response optimisation
- INP under 200 milliseconds by reducing main thread blocking and deferring non critical JavaScript
- CLS under 0.1 by reserving space for images and eliminating late injected elements
JavaScript Rendering Strategy
Server side rendering or static generation for content critical pages, so both Googlebot and AI crawlers can read your content without executing scripts.
What we target
- Rendered versus raw HTML comparison via Search Console URL Inspection
- Hydration mismatch detection where interactive elements load after initial render
- Confirmation that critical pages return content before JavaScript loads
Crawlability and Indexation
Misconfigured robots.txt files, blocked CSS or JavaScript, and bloated sitemaps quietly prevent discovery. Visibility to search engines is the prerequisite for everything else.
What we target
- Crawl budget consolidation by blocking low value URL patterns and reducing parameter proliferation
- XML sitemaps containing canonical URLs only, with accurate lastmod dates
- Orphaned page identification and internal link depth mapping
Canonical and Duplicate Content
Over 60 percent of enterprise sites carry conflicting canonical signals or malformed hreflang, splitting ranking authority across URLs that should be consolidated into one.
What we target
- Canonical consistency across every template and URL variation
- Correct hreflang implementation using full ISO codes for international sites
- Consolidation of duplicate and near duplicate pages competing against each other
Schema Markup and Structured Data
Structured data now drives both Google rich results and AI citations. Errors here cost eligibility for features that can meaningfully increase organic click through rate.
What we target
- Full entity graph implementation covering Organization, WebSite, and WebPage
- Service, FAQ, Article, and Breadcrumb schema where genuinely applicable
- Validation against Google's Rich Results Test with errors resolved, not ignored
Site Architecture and Internal Linking
Internal linking is consistently undervalued in technical audits, treated as a content task when it is genuinely a structural one that distributes authority across your site.
What we target
- Logical hierarchy keeping important pages within a shallow click depth
- Deliberate internal link distribution toward revenue generating pages
- Elimination of orphaned pages and broken internal link chains
Mobile First and Content Parity
Google indexes the mobile version of your site as primary. Content hidden behind tap to expand elements on mobile can effectively disappear from what gets indexed.
What we target
- Full content parity between mobile and desktop versions
- Mobile usability issues resolved across every template
- Mobile specific performance optimisation, where most real users actually are
AI Crawler Access and Readiness
Blocking GPTBot, ClaudeBot, or PerplexityBot without a strategic reason forfeits AI citations entirely. Most sites do this by accident, not by decision.
What we target
- AI crawler access audited and configured deliberately, not left to defaults
- Semantic content structure that AI systems can interpret and cite accurately
- Entity clarity so AI systems correctly associate your brand with your category
How We're Different
What Most Agencies Deliver
vs What We Actually Do.
The Typical Technical Audit
- An exported tool report with hundreds of issues and no prioritisation
- Recommendations handed over with no implementation support
- Issues listed by ease of fixing rather than business impact
- No mention of AI crawler access or rendering strategy anywhere
- A one time audit with no ongoing monitoring afterwards
What We Actually Deliver
- A prioritised fix list ranked by genuine revenue impact
- Direct implementation, or collaboration with your development team
- Rendering and AI crawler strategy treated as core, not optional
- Continuous monitoring so new issues are caught before they cost rankings
- Plain language reporting explaining what changed and why it mattered
You can publish the best content in your industry and earn genuinely authoritative links, and none of it will compound if search engines cannot crawl, render, and correctly attribute your pages. Technical SEO is not the exciting part of search, but it is the part that decides whether everything else you invest in actually works.
This is why every Intertising engagement begins here. We do not build content strategy on top of a damaged foundation, and we do not sell authority building to a site that search engines are struggling to index. Fix the foundation, then build on it. That sequence is not negotiable, because reversing it wastes a client's budget.
Our Process
How We Approach
Technical SEO.
Complete technical audit
Every page crawled and analysed against current search engine standards, including Core Web Vitals, rendering behaviour, crawl budget usage, canonical consistency, and AI crawler accessibility.
Priority fix list
Issues ranked by genuine business impact, so the fixes that move rankings fastest are addressed first, not the ones that are simply easiest to complete.
Implementation
Our team implements every fix directly, or works alongside your developers if you prefer to keep changes in house. We speak to engineering teams in their language, not in exported PDFs.
Ongoing monitoring
Technical health is monitored continuously so new issues introduced by site changes, deployments, or platform updates are caught and resolved before they affect rankings.
Common Questions
What Businesses Ask
About Technical SEO.
Because most AI crawlers do not execute JavaScript at all. If your critical content only renders after scripts run, it is invisible to systems like ChatGPT, Perplexity, and Claude, even if it ranks perfectly well on traditional Google results. Server side rendering or static generation solves this, and it has become a business decision rather than a purely technical one.
Interaction to Next Paint replaced First Input Delay as a Core Web Vital. It measures the full delay between any user interaction and the next visual update, targeting under 200 milliseconds. It is the most commonly failed metric because it requires optimising JavaScript execution across the entire session, not just page load. Heavy third party scripts, analytics, chat widgets, and unoptimised components are the usual causes.
Technical fixes often show faster movement than content or link building, because you are removing barriers rather than building new authority. Crawl and indexation fixes can show effects within weeks. Core Web Vitals improvements typically need 28 days of field data before Google reflects them fully.
We implement. A prioritised report with no execution behind it is the single most common failure in technical SEO engagements. We either implement directly or work inside your development workflow alongside your engineers, depending on what your team prefers.
Usually not, unless you have a specific strategic reason. Blocking them forfeits AI citations entirely, which is an increasingly significant discovery channel. Many sites block these crawlers accidentally through inherited robots.txt configurations they have never audited.
Both. There is usually an initial phase of fixing accumulated technical debt, followed by ongoing monitoring. Sites change constantly through deployments, plugin updates, and content additions, and each of those can introduce new technical issues. A site audited once and never checked again typically regresses within months.
