SEO diagnosis for large Shopify stores and catalogue-heavy websites

Technical SEO

Technical SEO that fixes crawling, rendering, and indexation blockers

If important pages are not being crawled, rendered, indexed, or trusted correctly, we identify the technical blockers and fix them in priority order.

For websites where crawl, render, indexation, performance, or URL signals are suppressing otherwise valuable pages.

Recognition signals

You probably need this when...

Technical SEO problems suppress performance long before they become obvious internally, especially when crawl behaviour, rendering, migrations, and page performance are left unresolved.

Important pages are not being indexed properly

If search engines cannot include the right URLs in the index, the site cannot compete where it matters.

Rendering and crawl behaviour are working against the site

Key content may be delayed, hidden, or de-prioritised because the technical setup is harder for search engines to process.

Migrations and URL changes create unstable signals

Redirect chains, inconsistent canonicals, and mixed internal links can weaken visibility quickly after launch.

Performance issues affect both rankings and UX

Slow templates and unstable page behaviour reduce the site's ability to rank and convert search traffic.

Large sites accumulate hidden structural debt

Small technical issues repeated across templates and sections become a serious visibility problem over time.

How it works

How we approach technical SEO problems

We diagnose the technical surface first, then prioritise the fixes most likely to change search performance.

  1. 01

    Understand the technical surface

    Crawl paths, templates, rendering, index signals, internal links, and performance constraints.

  2. 02

    Find the failure patterns

    Canonical conflicts, crawl traps, render gaps, duplication, speed issues, and structural blockers.

  3. 03

    Prioritise the fix sequence

    Start with the technical changes most likely to be processed and change search performance.

Evidence we use

The diagnosis is built from page-group evidence

Crawl

Reach and waste

Find whether search engines can reach the right templates efficiently.

Used to decide what deserves crawl, indexation, links, or implementation effort.

Index

Eligibility and selection

Separate discovery problems from quality or canonical problems.

Used to decide what deserves crawl, indexation, links, or implementation effort.

Render

Visible output

Check what important content and links are available after rendering.

What we actually look at

Technical SEO investigation areas

A review of the technical conditions affecting how important URLs are discovered, processed, and included in search.

Crawl and indexation

  • Crawl paths
  • Index coverage
  • Robots and noindex rules

URL signals

  • Canonicals
  • Redirect chains
  • Sitemaps

Rendering

  • Rendering behaviour
  • JavaScript output
  • Core Web Vitals

Site structure

  • Internal links
  • Template duplication
  • Structured data

Evidence and proof

How this shows up in real work

Technical proof is clearest when symptoms, root cause, and the fix sequence can be traced through crawl, index, and URL evidence.

Large Shopify catalogue diagnosis and prioritisation

View project context →

Diagnosis file #005

Traffic decline after a Shopify migration

Shopify

Problem

Thousands of live Shopify products were discoverable, but only a small share were indexed.

Diagnosis

Faceted URLs, weak internal links, and uneven template quality were pulling crawl attention away from priority products.

Outcome

Priority collections recovered once migration signals were consolidated.

Outputs

What the work produces

The output is designed for decisions and implementation, not for filling a report with every possible SEO issue.

Prioritised technical issue list

A ranked view of the technical blockers most likely to suppress visibility right now.

Clear explanation of the root causes

We show what is wrong, why it matters, and how the issues connect across the site.

Actionable fixes for internal or dev teams

Recommendations are designed to be implemented, not just reported.

Optional rollout support

If needed, we can help move the changes through implementation and validation.

Questions before starting

How quickly can Technical SEO changes make a difference?+

Some crawl and indexation improvements appear within weeks, while larger recoveries depend on crawl cycles, implementation quality, and competition.

How long does Technical SEO take?+

The first useful diagnosis is normally built around a focused evidence pass rather than a long discovery phase. Larger catalogues, generated page systems, and migration issues can take longer because the work needs to be checked by template, URL cohort, and commercial priority.

Who implements the recommendations?+

That depends on the team and platform. We can hand over developer-ready recommendations, work alongside an internal SEO or development team, or support implementation where the fixes need closer technical interpretation.

Can this work alongside an existing agency or in-house team?+

Yes. Better Ranking is often most useful as the diagnostic and prioritisation layer: identifying the cause, setting the fix order, and helping existing teams focus on the changes most likely to move search performance.

If technical blockers keep search engines away from your best pages, competitors with cleaner setups will keep taking the visibility.
