Technical SEO

Technical SEO that clears the path to rankings and AI citations.

The best content in the world cannot rank if crawlers cannot reach it, render it, or trust it. LYNX finds the crawl, speed, structure and schema issues quietly capping your site, then fixes them, or hands your developers a roadmap they can actually ship.

Technical SEO is the practice of optimizing a website's infrastructure, its crawlability, indexation, rendering, speed, architecture and structured data, so search engines and AI answer engines can find, understand and cite every page that matters. A technical SEO agency runs a full site audit, prioritizes the issues by revenue impact, and either implements the fixes or delivers a developer-ready roadmap. LYNX does both. We ship what we can directly, hand your engineers ticketed fixes for the rest, and build every change so your pages are not just crawlable and fast for Google, but structured to be retrieved and quoted by ChatGPT, Perplexity, Gemini and Google AI Overviews.

The technical audit, live

Watch a site get diagnosed and fixed.

This is a LYNX technical audit, compressed. Pick a site type to run it against, or watch it cycle. The console crawls, scores the damage, then applies the fix roadmap while the health dial climbs.

What is included

The full technical foundation, handled.

Everything that decides whether search engines and AI systems can crawl, render, trust and cite your site, diagnosed and fixed in one place.

01

Full technical audit & prioritized roadmap

A 200-plus point crawl of your site, findings ranked by revenue impact, delivered as tickets with the affected template, the fix, and the expected result. No 90-page PDF that dies in a drawer.

02

Crawlability & indexation

We audit crawl budget, robots.txt, XML sitemaps, canonicals and noindex rules so every important page is reachable and indexed, and every low-value URL stays out of the crawl.

03

Core Web Vitals & page speed

We find what drags LCP, INP and CLS: render-blocking resources, heavy images, bloated JavaScript, then fix it so real users and ranking systems see a fast, stable page.

04

Site architecture & internal linking

We flatten deep structures, fix orphan pages, and route internal links so authority flows to the pages that earn revenue and crawlers grasp your hierarchy.

05

Structured data & schema

Valid, error-free schema that wins rich results and, just as importantly, gives AI answer engines the entities they need to quote you as the source.

06

JavaScript, migrations & international

Rendering fixes so crawlers see your content, safe site migrations with full 301 mapping, and clean hreflang and canonicalization across every market.

Try it yourself

Core Web Vitals, made tangible.

Core Web Vitals are three ranking signals Google measures on real visits. Drag the levers to see how media, JavaScript and layout stability move LCP, INP and CLS, and whether your page would pass. These are the exact thresholds Google uses.

Google's thresholds: LCP good under 2.5s, poor over 4s. INP good under 200ms, poor over 500ms. CLS good under 0.10, poor over 0.25. A page passes Core Web Vitals only when all three are good at the 75th percentile of real visits.

Why most audits fail

The problem is not finding issues. It is fixing the right ones.

The 90-page PDF

An audit that just gets filed

Most agencies hand you an exhaustive list of every flag a tool could raise, unranked, with no owner and no context. Your developers cannot tell a critical indexation bug from a cosmetic warning, so nothing ships and rankings never move.

A ticketed roadmap

The 5% that moves the number

We surface the handful of issues actually suppressing revenue, rank them by impact, and deliver each as a ticket your team can pick up: the file, the change, the expected result. Then we implement the ones we can ourselves.

Flagship case study

When the content was fine, but the site was invisible.

An enterprise retail catalogue, one technical engagement, twelve months. Nothing wrong with the products or the copy. The site was burning crawl budget on junk URLs while its money pages sat unindexed and slow. We cleared the path.

The Challenge
  • Faceted navigation spawned millions of near-duplicate URLs, eating crawl budget
  • Only a third of real product pages were actually indexed
  • LCP over 4.5 seconds on mobile, with only 12% of pages passing Core Web Vitals
The Results
  • Crawl rules and canonicals cut wasted crawling by 71%
  • Valid indexed pages up 289% as the money pages became reachable
  • Core Web Vitals pass rate went from 12% to 94% after speed work
  • Non-brand clicks up 167% with no new content, just access
  • Product pages now surfaced and cited in AI shopping answers
How we work

Crawl, prioritize, implement, protect.

STEP 01

Crawl & diagnose

A full crawl and render of your site against 200-plus checks, cross-referenced with Search Console and real field data.

STEP 02

Prioritize by impact

We rank every finding by what it costs you in rankings and revenue, not by how loud a tool flagged it.

STEP 03

Implement

We ship the fixes we can directly, and hand your developers ticketed changes for the rest, with the file and the expected result.

STEP 04

Monitor & protect

Ongoing crawl monitoring and regression alerts catch new issues, and safe migrations keep rankings intact when the site changes.
