SEO website audit: how to identify issues and improve your Google rankings

JS Digital IQ is a digital delivery consultancy running website audits, redesigns and migrations for UK businesses that need their site to rank and convert, not just look tidy.

The majority of issues with websites are not obvious from the front end. The homepage loads, the menu works, the contact form sends. Everything looks fine.

Then you check Search Console and find 400 pages indexed that you did not know existed, half your product pages sharing the same title tag, and a redirect chain from a rebuild two years ago quietly bleeding authority into nothing.

An audit is how you find that. Here is how to run one properly.

Start With a Crawl, Not With Opinions

Before anyone discusses design or copy, crawl the site. Screaming Frog, Sitebulb or an equivalent will give you the actual structure rather than the one you think you have.

What the crawl tells you in the first ten minutes:

• Status codes — how many 404s, 301s, 302s and redirect chains exist
• Duplicate titles and meta descriptions across pages
• Missing H1s or multiple H1s per page
• Pages that are orphaned and lack internal links
• Thin pages under a few hundred words that dilute your topical focus

A Website Audit Consultant worth their fee starts here every time, because the crawl reframes the conversation from taste to evidence.

Check What Google Has Actually Indexed

The crawl shows what exists. What Google chose to retain is seen in Search Console.

Compare the two. Your issues reside in the gap:

1. Pages indexed but not in your sitemap — usually parameter URLs, tag archives or staging leftovers
2. Pages in your sitemap but not indexed — Google evaluated them and passed
3. Duplicate or canonical conflicts where multiple URLs compete for the same query
4. Crawl budget waste on filtered or paginated pages nobody searches for

At JS Digital IQ we treat this comparison as the single most revealing part of any audit. It shows what Google thinks your site is about, which is rarely what you intended.

Technical Health

Then work through the technical layer:

• Core Web Vitals, particularly on mobile, where most sites fail first
• Mobile rendering — not just responsive, but usable with a thumb
• HTTPS and mixed content warnings
• XML sitemap accuracy, with no 404s or redirects listed
• Robots.txt not blocking anything important, including AI crawlers if you want AI visibility
• Structured data implemented and passing validation

Most of these are fixable in days. They are also the ones most often left for later and then forgotten.

The Content and Intent Layer

Technical fixes remove barriers. They don’t make ranks by themselves.

For each important page, ask three questions:

• Does this page match a real search intent, or does it exist because the site map needed filling?
• Is the primary topic obvious from the title, H1 and first paragraph?
• Is there a stronger page on our own site competing with it?

That last one catches out most businesses. Internal cannibalisation, where three pages target the same phrase, is more common than any external competition problem.

Do Not Stop at Rankings

An audit that only measures visibility misses half the picture. Traffic that arrives and leaves is not a win.

A CRO Consultant UK businesses bring in will check the conversion layer alongside the SEO layer:

• Clarity above the fold about what you do and who for
• One obvious next action per page rather than five competing buttons
• Reviews, case studies, and client logos are examples of tangible evidence.
• Fast mobile loading, which is a ranking factor and a conversion factor simultaneously
• Forms that can be completed in less than a minute.

Most sites fail on the first and the last. Fixing those two often moves enquiries more than any keyword work.

Running SEO and CRO Consultant UK analysis together also stops the classic own goal: adding content that ranks beautifully and converts nobody.

The Migration Question

If your audit concludes that a rebuild is needed, this next part matters more than everything above it.

A redesign can lose most of your organic traffic overnight. It happens when URLs change without 301 redirects, when content gets cut during the tidy-up, or when technical SEO simply is not carried across.

A Website Migration Consultant should be doing this before anything is built:

1. Crawl and map the old site in full, capturing every indexed URL
2. Match old URLs to new, one by one, with no guesswork
3. Implement 301 redirects, avoiding chains
4. Preserve high-performing content rather than rewriting it for freshness
5. Carry across title tags, schema and internal linking structure

We have run this process at both ends of the scale — a regulated SME launch for London FS and an enterprise CMS redesign for NAG on IBM WebSphere. The discipline is identical; only the volume changes.

Skipping the mapping step is the most expensive shortcut available in digital.

QA Before Launch, Not After

Testing gets squeezed when timelines slip, and it should not be.

A Website QA Consultant checks the things that break silently: forms actually delivering to the right inbox, tracking firing on the correct events, redirects resolving in one hop, pages rendering on real devices rather than a browser resize.

One rule worth holding to: GA4 and Google Tag Manager should be configured and tested before go-live, with conversion events defined. Retrofit them afterwards and you lose the launch-period baseline you need to judge whether the redesign worked. That baseline cannot be recovered later.

Who Holds It Together

Audits generate findings. Findings need an owner, or they become a PDF nobody opens.

This is where a Digital Project Manager Freelance engagement earns its place — sequencing fixes, coordinating designers and developers against scope, and keeping the list moving. Most redesign delays come from content approval rather than development, so agree who signs off before anything starts.

Prioritise Ruthlessly

You will not fix everything. Sort findings into three buckets:

• Fix now — indexation errors, broken redirects, missing tracking, mobile failures
• Fix soon — duplicate content, thin pages, internal linking, page speed
• Plan properly — structural changes, migrations, full rebuilds

Why Choose Us

JS Digital IQ brings nearly twenty years of enterprise digital experience — across brands including Unilever, PMI, GSK and Costa Coffee — applied directly to growing UK businesses. We audit sites the way we build them: crawl first, evidence before opinion, analytics wired in from the start rather than bolted on afterwards. As a Website Audit Consultant clients trust for straight answers, we tell you which findings will move the needle and which are simply noise in a tool report.

Conclusion

A useful audit is not a 200-point checklist exported from software. It is a short, prioritised list of the things genuinely holding your site back, ordered by impact. Crawl the site, compare it against what Google indexed, fix the technical barriers, check whether the pages convert once people arrive, and map every URL carefully before any rebuild goes ahead. Do that and rankings improve as a by-product of a site that works properly. Start with the crawl this week and see what turns up.
