SEO Audit: What It Should Cover, What You'll Find, and What to Fix First

An SEO audit is an assessment of a website's technical health, content quality, and link profile — with the goal of identifying what's preventing stronger organic performance. The term is used loosely in the industry, covering everything from a quick crawl report to a multi-month strategic review.

This guide focuses on what a rigorous, useful SEO audit actually covers, what you're likely to find, and how to prioritise the output into an action plan that improves rankings.

What a Comprehensive SEO Audit Should Cover

Technical SEO Health

Technical issues prevent your content from being crawled, indexed, and ranked even when the content itself is strong. A technical audit covers: crawl coverage and indexation status, Core Web Vitals performance, site architecture and internal link structure, HTTPS and redirect configuration, mobile usability, structured data implementation, and duplicate content and canonicalisation issues.

On-Page and Content Quality

Content quality analysis examines whether your pages are well-positioned to rank for the keywords they're targeting. This includes: keyword targeting and content alignment, title tag and meta description optimisation, heading structure and content depth, E-E-A-T signals and content authoritativeness, duplicate or thin content, and cannibalization between pages targeting similar keywords.

Backlink Profile Analysis

Your link profile — the quantity, quality, and diversity of websites linking to yours — is one of the strongest signals in Google's ranking algorithm. A link audit identifies: total referring domain count and growth trend, domain authority distribution of linking sites, anchor text distribution, toxic or spammy links that may be triggering manual or algorithmic penalties, and link acquisition opportunities based on competitor analysis.

Competitor Benchmarking

Understanding where you stand relative to competitors who rank above you for your priority keywords provides crucial context for prioritisation. Which technical advantages do they have? How does their content depth compare? How many more high-quality backlinks do they have? The gap analysis shapes the strategic priority order of your audit recommendations.

What You'll Find: Common Audit Discoveries

Indexation Issues

A substantial proportion of sites have pages unintentionally blocked from indexation — by misconfigured robots.txt, accidental noindex tags, or canonicalization errors. These are high-priority fixes because they directly prevent pages from appearing in search results, regardless of content quality.

Core Web Vitals Failures

Most sites have at least some pages failing Core Web Vitals thresholds, with LCP being the most common failure point. Large, unoptimised hero images are the single most frequent cause.

Keyword Cannibalization

Sites that have published content over time without a systematic keyword strategy frequently have multiple pages competing for the same keywords. This splits ranking signals and results in neither page performing as well as a single consolidated page would.

Thin or Outdated Content

Pages that were published with insufficient depth, or that were strong several years ago but haven't been updated as the competitive landscape evolved, typically underperform their potential. Identifying these pages for refresh or consolidation is a high-ROI activity.

How to Prioritise Audit Findings

Not all audit findings have equal ranking impact. Prioritise in this order: first, fix anything that prevents indexation; second, address Core Web Vitals failures on high-traffic pages; third, consolidate cannibalizing content; fourth, refresh high-priority pages with thin or outdated content; fifth, build links to pages that are ranking on page two for high-value keywords.

A good SEO audit doesn't end with a list of issues — it ends with a prioritised implementation plan that accounts for development resource constraints, content team capacity, and the likely ranking impact of each fix.
