What an SEO audit is
An SEO audit is a practical review of your website's search performance.
The point is not to produce a fancy spreadsheet.
The point is to answer a simple question: what is stopping this site from performing better in search?
Most audits end up surfacing a mix of:
- technical issues
- indexing problems
- weak or missing content
- broken internal structure
- authority gaps
When a site probably needs an audit
An audit is worth doing if any of these sound familiar:
- traffic has stalled
- rankings dropped suddenly
- pages are not appearing in search
- a redesign or migration recently happened
- competitors are overtaking you
- traffic is coming in but not converting well
Step 1: Check indexing first
Before anything else, make sure Google can actually see the important pages.
In Google Search Console, look at the Pages report and compare:
- how many pages you expect to be indexed
- how many pages are actually indexed
- which pages are excluded
Pay particular attention to pages marked as:
- Crawled, currently not indexed
- Discovered, currently not indexed
- Error
If the right pages are not indexable, the rest of the audit matters less.
Step 2: Crawl the site
A crawl helps you see the site more like a search engine does.
Useful tools:
- Screaming Frog
- Google Search Console
- our SEO audit tool
Things to check during a crawl:
- broken links
- redirect chains
- missing title tags
- duplicate titles or meta descriptions
- orphan pages
- duplicate or near-duplicate URLs
Step 3: Review speed and Core Web Vitals
Speed affects both user experience and search performance.
Use:
- PageSpeed Insights
- GTmetrix
- our SEO Audit Tool
Main metrics to watch:
| Metric | Good target |
|---|---|
| LCP | under 2.5s |
| INP | under 200ms |
| CLS | under 0.1 |
Common fixes include:
- compressing images
- reducing unused JavaScript
- lazy loading below-the-fold content
- improving caching
- serving assets through a CDN
Step 4: Check on-page SEO
Every important page should have the basics in place.
Review:
This is also the point where you check whether the page is targeting the right search intent.
A well-optimised service page can still struggle if the searcher really wanted a guide. The opposite is also true.
Step 5: Review content quality
Content review is usually where the biggest growth opportunities appear.
Look for:
- thin pages
- outdated pages
- missing questions your audience is clearly searching
- pages that overlap too much
- content that does not match the search intent well
A useful question here is simple.
If someone lands on this page from Google, does the page actually solve the problem that brought them there?
Step 6: Check backlink quality
Backlinks still matter, but quality matters much more than raw volume.
A good backlink review should look at:
- how many referring domains you have
- the quality of those domains
- whether the links are relevant
- whether there are spammy or toxic patterns
- how your profile compares to competitors
Useful sources for a quick look:
- Google Search Console
- Ahrefs Free Backlink Checker
- Moz Link Explorer
Step 7: Compare against the pages already winning
An SEO audit without competitor context is incomplete.
For your important keywords, compare your page to the top-ranking pages on:
- content depth
- page speed
- internal linking
- backlink support
- search intent match
This helps you avoid fixing low-impact details.
It also helps you focus on the real gap between your page and the pages already performing well.
How to prioritise the fixes
Not all problems deserve equal attention.
Fix first
- pages Google cannot crawl or index
- major redirect or broken-link issues
- critical speed problems
- important pages missing core metadata
Fix next
- thin content on important pages
- weak internal linking
- duplicate content issues
- missing structured data where it helps
Build over time
- new content to fill topic gaps
- link acquisition
- deeper page improvements
When to bring in outside help
A basic audit is manageable for many teams. Extra help usually makes sense when:
- the site is large
- rankings dropped without an obvious cause
- the site recently migrated
- the stack is technically complex
- the market is highly competitive
A simple prioritisation model
Not every issue in an audit deserves equal urgency.
| Priority | Typical examples | Why it comes first |
|---|---|---|
| High | indexation blocks, broken canonicals, major crawl errors | They stop pages from competing at all |
| Medium | weak metadata, thin service pages, missing internal links | They limit visibility and conversion quality |
| Lower | smaller formatting issues or secondary enhancements | Useful, but not usually the main blocker |
This is why a good audit does not only list problems. It helps you decide what to fix first so the next month of work is focused.
What a useful audit deliverable should contain
A good audit deliverable should leave you with more than a list of problems.
It should usually include:
- the issue
- why it matters
- which pages are affected
- how urgent it is
- what the next action should be
That makes the audit easier to turn into actual implementation work.
Once the issues are prioritised properly, the audit stops being a research task and starts becoming a roadmap the team can actually execute against.
That structure also makes it much easier to hand the findings off to developers, writers, or marketers without losing momentum between diagnosis and action.
FAQ
How long does an SEO audit take?
A lighter audit can take a few hours.
A deeper audit with competitor comparison and content review can take a day or more. It depends on the size of the site.
How often should I audit a site?
Light checks can happen monthly.
A fuller audit is worth doing quarterly, and again after any major redesign, migration, or CMS change.
What should I check first?
Indexing. If Google cannot index the pages that matter, the rest of the work becomes secondary very quickly for the whole site.
Can I audit a site with free tools?
Yes, for a basic review.
Google Search Console, PageSpeed Insights, and the free tier of Screaming Frog cover a lot of ground.
What happens after an audit?
You should have a prioritised list of actions, not just observations.
The value of the audit is in the fixes that follow.
That is also why the best audits usually end with owners, deadlines, and an implementation order instead of a generic list of findings.
Conclusion
A good SEO audit turns guesswork into a plan.
Instead of asking why a site is underperforming in general, you get a clearer picture.
You can see what is broken, what is weak, and what needs attention first.
That is where meaningful progress usually starts.
