What is technical SEO?
Technical SEO is the practice of optimising a website's infrastructure so search engines can crawl, render, index and understand it without friction. It covers everything that happens before content and links can do their job: how fast pages load, whether bots can reach every URL, how the site is structured, and how clearly the markup communicates meaning to machines.
Think of it as the foundation under a building. You can publish excellent content and earn strong backlinks, but if Googlebot cannot crawl your pages, render your JavaScript, or index the canonical version, that work never reaches the search results. At Khan IT in Vancouver, Canada, technical SEO is where most of our engagements begin, because it is usually where the largest and fastest wins are hiding.
Technical SEO also underpins answer engine and AI search visibility. Clean HTML, fast rendering and accurate structured data make your pages easier for large language models and AI Overviews to parse and cite, which is why it works hand in hand with our AI SEO service.
Why does it matter so much now? Search engines crawl a finite share of the web each day, render pages under tight time budgets, and increasingly summarise answers without sending a click. A site that loads slowly, blocks resources, or buries content behind unrendered JavaScript loses on all three fronts. Getting the technical layer right is no longer optional housekeeping; it is the difference between content that compounds in value and content that never gets discovered. Vancouver, Canada businesses competing in crowded local and national niches simply cannot afford avoidable technical drag.
What does a technical SEO audit include?
A technical SEO audit is a systematic inspection of every factor that affects how search engines access and interpret your site. We crawl your domain the way Googlebot does, cross-reference it with server log files and Google Search Console data, then prioritise issues by traffic impact and effort.
A Khan IT technical audit typically reviews:
- Crawlability: robots.txt rules, crawl budget, orphan pages, redirect chains and broken links.
- Indexability: noindex tags, canonical signals, XML sitemap accuracy and coverage reports.
- Core Web Vitals and page speed: LCP, INP and CLS against real-user field data.
- Site architecture and internal linking: URL structure, click depth and link equity flow.
- Structured data: schema coverage, validity and eligibility for rich results.
- JavaScript rendering: whether critical content and links are visible to crawlers.
- Mobile-first and security: responsive behaviour, HTTPS and security headers.
- Duplicate content and hreflang: canonicalisation and any international targeting.
You can book a free technical SEO audit with our team and we will walk you through the findings in plain language, with a prioritised remediation plan attached.
How do you fix crawlability and indexing issues?
You fix crawlability and indexing by making sure search engines can reach every important URL and are told exactly which version to index. Crawlability is whether a bot can find and fetch a page; indexability is whether that page is eligible to be stored and ranked. Both must pass before a page can appear in results.
Crawlability
We audit your robots.txt to confirm it is not blocking CSS, JavaScript or key directories, eliminate redirect chains and 404s that waste crawl budget, and surface orphan pages that have no internal links pointing to them. For large sites we analyse server log files to see which URLs Googlebot actually requests and how often, so crawl budget is spent on pages that matter. Log analysis frequently exposes problems no crawler simulation can, such as bots hammering faceted-navigation parameters, infinite calendar URLs, or stale paths that should have been retired months ago.
We also tighten internal signposting so discovery is efficient: a clear navigation, an HTML breadcrumb trail, and contextual links that lead crawlers from popular pages to deeper ones. The goal is simple, every page worth ranking should be reachable, and nothing that wastes budget should be crawlable.
Indexability
We keep your XML sitemaps accurate and limited to canonical, indexable URLs, then validate them against Search Console coverage reports. We resolve conflicting signals, such as a page that is in the sitemap but carries a noindex tag, and set correct canonical tags so duplicate or parameterised URLs consolidate ranking signals onto one address.
What are Core Web Vitals and what are the thresholds?
Core Web Vitals are three field metrics Google uses to measure real-world page experience: Largest Contentful Paint, Interaction to Next Paint, and Cumulative Layout Shift. They are assessed at the 75th percentile of real-user data, meaning at least 75% of visits must meet the "good" threshold for a page to pass.
| Metric | What it measures | Good | Needs work | Poor |
|---|---|---|---|---|
| LCP (Largest Contentful Paint) | Loading: time to render the largest visible element | < 2.5s | 2.5s – 4.0s | > 4.0s |
| INP (Interaction to Next Paint) | Responsiveness: latency of user interactions | < 200ms | 200ms – 500ms | > 500ms |
| CLS (Cumulative Layout Shift) | Visual stability: unexpected layout movement | < 0.1 | 0.1 – 0.25 | > 0.25 |
INP replaced First Input Delay as a Core Web Vital in March 2024 and remains the responsiveness metric in 2026. To improve these scores we optimise page speed end to end: compressing and lazy-loading images, serving modern formats, deferring non-critical JavaScript, reserving space for media to prevent layout shift, and reducing main-thread work so interactions stay snappy. Our website development team can rebuild slow templates from the ground up when patching is not enough.
Site architecture and internal linking
A flat, logical site architecture helps both users and crawlers reach any page in a few clicks and distributes ranking signals to your most important pages. We organise content into clear hubs and subtopics, keep important pages within three clicks of the home page, and use descriptive, lowercase URLs that reflect that hierarchy.
Internal linking is the lever that moves authority through the site. We add contextual links from high-authority pages to priority targets, fix broken and redirected internal links, and use clear, keyword-relevant anchor text. Strong internal structure also reinforces topical relevance, which supports both classic rankings and your local SEO in the Vancouver, Canada market.
Architecture decisions also affect crawl efficiency and user experience together. Deeply nested pages buried six or seven clicks down rarely get crawled often or rank well, so we flatten unnecessary depth, retire thin and duplicate templates, and group related pages under coherent parent directories. The pattern we aim for is a small number of strong hub pages, each supported by a cluster of focused supporting pages that link back up. This hub-and-spoke shape concentrates authority where it converts and makes the whole site easier for both people and machines to navigate.
How does structured data help SEO?
Structured data is standardised markup, usually JSON-LD using the Schema.org vocabulary, that tells search engines what your content means rather than just what it says. It does not directly boost rankings, but it makes pages eligible for rich results and gives AI engines unambiguous facts to cite.
For a Vancouver, Canada service business, we commonly implement:
- LocalBusiness with accurate name, address and phone for local visibility.
- Service and BreadcrumbList for service pages and navigation.
- FAQPage to surface questions and answers and feed AI summaries.
- Organization and WebSite for brand and sitelinks signals.
We validate every implementation against Google's Rich Results Test and Schema.org so the markup is error-free and matches visible page content, which is a requirement for eligibility. We deliver schema as JSON-LD injected into the page head, the format Google recommends, because it keeps markup separate from layout and is the easiest for engines to consume reliably. Beyond rich snippets, well-structured data is becoming a key signal for generative engines that assemble answers from trusted, machine-readable facts, so the same work that earns a review star or FAQ accordion in Google also improves your odds of being cited by AI assistants.
Mobile-first indexing, security and JavaScript rendering
Google indexes the mobile version of your site, renders JavaScript on a deferred second pass, and treats HTTPS as a baseline ranking signal. Each of these realities shapes how we build and fix sites in 2026.
Mobile-first
Because mobile-first indexing uses your mobile pages for ranking, we ensure the mobile experience contains the same content, structured data and links as desktop, with tap targets, font sizes and viewport settings that pass usability checks.
HTTPS and security
We confirm full HTTPS coverage with no mixed-content warnings, valid certificates and sensible security headers such as HSTS. Secure, trustworthy delivery supports both rankings and conversion.
JavaScript rendering
Search engines can render JavaScript, but it is slower and less reliable than HTML. When critical content or links only appear after client-side execution, indexing suffers. As real developers, we favour server-side rendering or static generation, frequently with Next.js, so primary content and links exist in the initial HTML response.
Handling duplicate content and international targeting
Duplicate content splits ranking signals across multiple URLs, and incorrect international tagging sends the wrong page to the wrong audience. We consolidate duplicates with canonical tags, consistent internal linking and 301 redirects where appropriate, so authority concentrates on a single preferred URL.
For sites targeting multiple languages or regions, including English and French audiences across Canada, we implement hreflang annotations correctly: self-referencing tags, valid language and region codes, and reciprocal references between every alternate. Done right, hreflang prevents duplicate-content conflicts between near-identical regional pages and serves each user the version meant for them.
