SEO audit shows strengths and weaknesses of a website from a search engine’s point of view. It helps uncover technical issues, evaluate content, check indexation and how your link architecture works. The outcome is a practical list of actions that improves visibility and unlocks organic growth.
Why you need an SEO audit
An SEO audit helps you find and fix issues that prevent your website from ranking higher. The technical layer shows how fast pages load, whether there are mobile problems, how indexation rules and redirects work and whether duplicate content exists. The content layer checks relevance of copy, keyword usage and whether pages match real user intent.
Internal linking is evaluated to see how easy it is for both users and crawlers to move through the site. The backlink profile is reviewed for domain quality, topical relevance and the share of risky links. Together these checks form a roadmap of fixes and growth opportunities.
Key stages of an SEO audit
1. Technical analysis
First, you check the technical health of the site:
- Page load speed and mobile friendliness.
- Code quality and redirect configuration.
- HTTPS and overall security.
- Optimization of CSS, JS and images.
2. Indexation and visibility
Then you look at how crawlers see the site:
- Correct work of
robots.txtandsitemap.xml. - Duplicate or low-value pages.
- URL structure and canonical tags.
3. Content audit
Content is the core of SEO. The audit covers:
- Uniqueness and relevance of materials.
- Use of target queries and their density.
- Optimization of headings, meta tags and image alt attributes.
Quick content audit checklist
- Uniqueness: no copy‑paste; copy is written for people first, crawlers second.
- Intent & keywords: queries are woven in naturally and match real search intent, not just exact phrases.
- Meta & structure: a single H1, logical H2/H3, unique title/description and useful alt attributes.
4. Internal linking and site structure
Search engines value clear, logical navigation. You check:
- Depth of page nesting.
- Number and quality of internal links.
- Presence of broken internal links.

Depth
≤ 3 clicks from home is healthy; 4+ levels need review.
Internal links
Aim for 2–5 relevant links to key pages from each important page.
Broken links
0–1% of total internal links is a reasonable benchmark.
5. Backlink profile analysis
SEO is impossible without a healthy backlink profile. It is important to:
- Determine the number and quality of backlinks.
- Find toxic links and prepare them for removal or disavowal.
- Analyse anchor lists and how balanced they are.

Tools for an SEO audit
A comprehensive SEO audit uses several specialized tools, each solving its own task.
Google Search Console shows how Google sees your site: indexation status, crawl errors, queries that drive traffic and the correctness of robots.txt and sitemap.xml. You also monitor mobile issues, Core Web Vitals and statuses of submitted URLs.
Google Analytics gives behavioural insight: where visitors come from, which devices they use, how they move through pages and where they drop off. This helps separate pages that generate conversions from those that lose users.
Ahrefs, SEMrush and Moz let you audit your backlink profile and competitors, explore keywords and design a data‑driven promotion strategy.
Screaming Frog and other crawlers scan the site and find technical issues, duplicates, redirect problems and broken or missing meta tags.
How to use audit results
After the SEO audit it is not enough to know about problems — you need to implement changes in the right order. The first step is prioritisation: critical technical errors that block indexation or hurt UX go first.
This includes fixing redirects, removing or fixing broken links, resolving duplicate content issues and improving performance.
Next comes content: reworking key pages around intent, enriching copy with real answers and examples, improving headings and meta tags, and tightening internal links.
Then you tackle external SEO factors — especially the backlink profile: removing toxic links, analysing competitors and building a strategy for acquiring quality mentions.
Audit results also influence wider marketing: you can improve UX, adjust site architecture and refine ad funnels based on the same data. SEO is a continuous process, so it makes sense to revisit metrics regularly and repeat the cycle.
In the end, an SEO audit is not just a PDF, but a working roadmap that, when implemented, strengthens visibility and brings more targeted leads from organic search.
