Technical SEO

Fix your foundation.
Unlock your rankings.

Without a solid technical foundation, even the best content and strongest backlinks underperform. Our Technical SEO service identifies and resolves every crawl, indexation, speed and architecture issue holding your website back — ensuring Google can discover, understand and rank your pages to their full potential.

The invisible ceiling

Most sites are not under-optimised. They are technically capped and nobody measured it.

Technical problems are the most expensive kind because they are silent. Content gets published, links get earned, budget gets spent — and none of it registers because pages cannot be rendered, crawl budget is consumed by parameter URLs, or mobile performance fails the thresholds that gate ranking. The work is invisible until someone crawls the site properly, at which point it is usually the highest-return fix available.

Crawl budget spent on nothing

Parameter URLs, faceted combinations, thin archives and redirect chains consume the crawl allocation your revenue pages need. On large sites this alone can leave a substantial share of the catalogue effectively unindexed.

JavaScript blocking indexation

Client-side rendered applications are frequently crawled poorly or not at all. It is the single most common reason a well-marketed site has no organic traffic, and it is invisible in every tool that does not render.

Failing mobile field vitals

Real-user metrics on mid-range mobile devices routinely fail even where desktop lab scores look fine. Those two disagree often, and only one of them affects rankings.

Architecture that buries revenue pages

Pages sitting five or six clicks deep receive minimal crawl priority and almost no internal authority. Flattening architecture is cheap and frequently produces movement within one crawl cycle.

What technical SEO covers

Content argues the case. Technical SEO makes sure the case is heard.

Technical SEO is everything determining whether search engines can discover, render, understand and prioritise your pages: crawlability, indexation, rendering, performance, architecture, structured data and international configuration.

It is the layer with the highest leverage and the least visibility. Unlike content or links, a technical fix can unlock hundreds of pages you have already paid to produce — which is why we sequence it first in essentially every engagement.

  • Crawl & index control — log-file analysis, crawl budget allocation, parameter handling, and deliberate decisions about what belongs in the index rather than platform defaults.
  • Rendering & JavaScript — verifying what engines actually see after rendering, and implementing server-side or static rendering where client-side execution blocks indexation.
  • Core Web Vitals — critical CSS, script deferral, image and font strategy, measured against real-user field data rather than synthetic lab scores.
  • Site architecture — flattening click depth, resolving orphans, and routing internal authority deliberately toward commercially important pages.
  • Structured data — validated schema for every rich result type your pages qualify for, implemented properly rather than emitted generically by a plugin.

Why this goes first: a technical fix can unlock hundreds of pages you already paid to create. It is the only SEO work where the return comes from content that already exists rather than content you have yet to build.

The Sachkhand blueprint

How we rebuild a technical foundation

Six workstreams, ordered by how much each unlocks relative to the effort it takes.

01

Crawl & log analysis

Full crawl plus server log analysis showing where crawl budget actually goes versus where it should. Logs reveal problems no crawler simulation can, and most sites have never looked at them.

02

Rendering verification

We check what engines see after rendering, not what your browser shows. Where JavaScript blocks indexation we specify server-side or static rendering and implement it with your engineering team.

03

Indexation control

Deliberate decisions about parameters, facets, archives and pagination. On large sites this typically removes thousands of URLs competing with the pages you actually want ranked.

04

Core Web Vitals

Critical CSS, script deferral, image and font strategy, caching and CDN configuration — targeted at mobile field data, which is where sites actually fail.

05

Architecture & internal links

Flattening click depth, resolving orphans, and routing authority toward revenue pages. Cheap, frequently overlooked, and often produces movement within one crawl cycle.

06

Schema & monitoring

Validated structured data plus ongoing monitoring, because technical health regresses silently as sites change and most teams have no alerting for it.

04
What is changing through 2026

Four shifts raising the technical baseline

Requirements keep tightening while sites keep accumulating weight. The gap between maintained and neglected infrastructure is widening quickly.

01

Index selectivity keeps increasing

Engines index a smaller proportion of what they crawl. Thin, duplicate and low-value URLs are not merely wasteful now — they can suppress how thoroughly your genuinely valuable content gets crawled.

02

Field data is the only score that counts

Real-user metrics determine Core Web Vitals status. Synthetic lab scores are a diagnostic tool, not an outcome, and optimising for them while field data fails is common and pointless.

03

INP replaced FID and is stricter

Interaction to Next Paint measures full interaction responsiveness rather than first-input delay. Many sites that comfortably passed the old metric fail the new one, particularly script-heavy commerce templates.

04

Rendering matters more as frameworks spread

As more sites ship as JavaScript applications, rendering strategy has become the difference between full indexation and near-invisibility. It is now a first-order SEO decision, not an implementation detail.

05
Why Sachkhand

We work in the codebase, with your engineers

Technical SEO fails when it arrives as a PDF nobody can action. We work alongside engineering rather than issuing recommendations over a wall.

Engineering-literate

We write tickets your developers can action, discuss trade-offs in their terms, and understand release constraints. That removes the usual gap between audit and implementation.

Log-file analysis as standard

We analyse server logs to see where crawl budget actually goes. Most audits skip this and consequently miss the problems that matter most on large sites.

Measured on field data

We optimise for real-user metrics from your actual visitors, not lab scores. Only one of those two affects rankings, and they frequently disagree.

Prioritised, not exhaustive

A 300-item audit avoids judgement. We tell you the handful of fixes that will actually move rankings and what to safely ignore, which is harder and far more useful.

Staging-first, always

Changes tested on staging with regression checks before production. Breaking a live site to improve its crawlability is not a trade we make.

Ongoing monitoring

Technical health regresses as sites change. We set up alerting so problems surface in days rather than being discovered in next year’s audit.

Measurement

Technical work should show up as rankings, not just green scores

Passing thresholds is a means. We track the technical indicators and the ranking movement they unlock.

Crawl efficiency

Proportion of crawl requests hitting valuable pages versus parameters, duplicates and errors — derived from actual server logs.

Index composition

Valid indexed pages versus excluded and thin URLs, tracked as indexation control takes effect.

Field Core Web Vitals

Real-user LCP, INP and CLS segmented by device, since mobile is almost always where sites fail.

Click depth & orphans

How deep revenue pages sit and how many pages remain unlinked, tracked as architecture is flattened.

Ranking movement

Position and traffic change on pages unlocked by technical work, which is what the whole exercise is for.

The engagement

Four stages, then continuous monitoring

Diagnose thoroughly, fix in controlled batches, then monitor so it does not silently regress.

01

Diagnose

Full crawl, server log analysis, rendering verification, field performance data and index composition review. You get a ranked remediation list with measured impact and effort against each item.

→ Ranked remediation plan
02

Fix the blockers

Rendering and indexation issues first, since these gate everything else. Implemented with your engineering team on staging, with regression checks before release.

→ Pages crawlable and indexed
03

Optimise

Core Web Vitals, architecture flattening, internal link routing and structured data. Released in controlled batches so impact stays attributable to specific changes.

→ Passing vitals + flat architecture
04

Monitor

Alerting on crawl anomalies, index drops and vitals regressions. Technical health degrades silently as sites change, so this is a standing workstream rather than a closing task.

→ Monitoring + monthly health report

To date

Targets set for engagements of six months or longer. Gains are largest on sites with substantial existing content being wasted by technical debt. Newer, well-built sites see smaller technical gains and rely more on content and authority work — the audit tells you which you are. These are planning targets rather than a record of past client averages; we agree a realistic range against your own baseline before an engagement starts.

Scenarios

Technical SEO in action — three sites

Different platforms and scales, the same principle: remove the ceiling and existing content starts working. The scenarios below are composites drawn from situations we encounter repeatedly — they illustrate method, not the account of any single named client.

SaaS platform

A React app that Google could not read

Challenge

A client-side rendered application with almost nothing indexed. Two years of content investment had produced essentially no organic traffic.

What we did

Implemented server-side rendering with the engineering team, corrected canonical and sitemap handling, and flattened architecture around key conversion paths.

Enterprise retail

Reclaiming crawl budget from parameter URLs

Challenge

Server logs showed the overwhelming majority of crawl requests hitting filter and sort parameters. New products took six weeks to index.

What we did

Implemented parameter handling and canonical rules, consolidated duplicate paths, rebuilt XML sitemaps by priority, and flattened category architecture.

Passing INP on a script-heavy template

Challenge

Comfortably passed the old FID metric and failed INP badly on mobile after the change, with rankings declining across the archive.

What we did

Audited and deferred third-party scripts, broke up long tasks, implemented critical CSS, and reworked ad loading to stop blocking interaction.

Questions

The questions we get asked most

Practical answers on scope, sequencing and what technical work can unlock.

What is technical SEO?+

Everything determining whether search engines can discover, render, understand and prioritise your pages — crawlability, indexation, rendering, site speed, architecture, structured data and international configuration. It excludes content quality and off-page authority, though all three have to work together for any of them to pay off.

How do I know if I have technical problems?+

The clearest signal is effort not converting into results: you publish good content, earn links, and rankings stay flat. Other indicators include pages taking weeks to index, large gaps between submitted and indexed URLs, and failing Core Web Vitals in field data. A crawl and log analysis settles it definitively.

Why does log-file analysis matter?+

Logs show what search engines actually did on your site rather than what a crawler simulation predicts. They reveal where crawl budget genuinely goes, which pages are crawled rarely, and which errors bots hit repeatedly. On large sites this routinely surfaces the highest-impact problems, and most audits never look.

Is JavaScript bad for SEO?+

Not inherently, but client-side rendering frequently is. Engines can execute JavaScript, though it happens in a deferred queue and often incompletely. Server-side rendering or static generation removes the risk entirely. For any content-critical site we treat client-side-only rendering as a problem to solve rather than a preference.

How long does technical SEO take?+

Auditing takes one to three weeks depending on site size. Remediation depends on engineering capacity — typically four to twelve weeks. Crawl and indexation improvements appear within weeks of fixes shipping. Core Web Vitals field data updates on a rolling 28-day window, so passing status becomes visible roughly a month after.

Do you implement fixes or just advise?+

Either. We can implement directly with access, write developer-ready tickets for your team, or work jointly. Most clients prefer the joint approach: we specify and verify, their engineers implement within their own release process. What we avoid is handing over a PDF and calling it done.

Will technical fixes alone improve rankings?+

Often substantially, when technical issues are the binding constraint — which is common on sites with a lot of existing content. Fixing indexation or rendering can unlock hundreds of pages already produced. On technically healthy sites the gains are smaller and content and authority become the constraint instead. The audit tells you which situation applies.

How often should technical SEO be reviewed?+

Continuously through monitoring, with a deeper review quarterly or after any significant change — replatforming, redesigns, major releases. Technical health regresses silently as sites evolve, and most teams discover problems months later. Alerting turns that into a days-long detection window.
