What does an SEO audit actually check?
A proper SEO audit is a full health check of your website, covering technical performance, on-page content, keyword targeting and backlink quality. It should tell you what's broken, what's holding you back and what to fix first, not just hand you a list of errors and leave you to work out the rest.
A good website SEO audit combines automated data with expert interpretation. Software can flag a slow-loading page in seconds, but it takes a real SEO specialist to explain why that page is actually costing you leads, and what to do about it.
We prioritise technical issues, not just list them
A long list of technical issues isn't much use if nobody tells you what to fix first. When we find problems on your site, whether that's a broken redirect, a crawlability issue or something bigger, we sort each one into critical/high, medium or low priority. That way you know exactly what needs attention now and what can reasonably wait, instead of a flat report that treats a missing alt tag the same way as an indexing error that's quietly costing you rankings.
It's a small distinction that makes a big difference to how useful an audit actually is. Fixing things at random, or working top to bottom through a list with no context, wastes time on low-impact tasks while the real blockers stay untouched. Prioritising by impact means the work you (or your development team) do first is the work that actually moves your rankings.
In practice, that usually looks something like this:
- Critical/high priority: broken internal links, poor crawlability and indexation, or Core Web Vitals problems slowing the site down on mobile, the kind of issues actively costing you visibility right now
- Medium priority: an outdated XML sitemap, weak internal linking or missing structured data, important but not urgent
- Low priority: smaller, useful wins like missing image alt text or a canonical tag review, worth doing but not going to move the needle on their own
Not every audit does the same job
Search for "SEO audit for business" and you'll find everything from free automated scans to five-figure enterprise reviews, and the differences matter more than most business owners realise. A basic audit might flag a handful of technical issues in minutes. A deeper audit digs into your competitors, your backlink profile and your entire site architecture, and takes a specialist team days to complete properly.
Neither approach is wrong. Using the wrong one for your situation is the problem, whether that means overpaying for depth you don't need or underpaying and missing the issue that's actually holding you back. That's the real answer to how to choose an SEO audit that fits your business, not just your budget.
How to choose an SEO audit that matches your warning signs
Before you choose an SEO audit, it helps to know what's actually prompting the search. Here are some of the most common warning signs we see, and what they usually point to:
- Rankings have dropped suddenly, which could mean a technical issue, an algorithm update or a lost backlink, and needs a proper technical dig
- Traffic's flat despite regular content, which often means your keyword targeting or on-page structure needs attention
- You've just launched a new site, where a foundational audit protects you from indexing and crawlability problems from day one
- Your last agency's reporting feels vague, which is a good reason to get an independent second opinion
- You're expanding into new products or locations, where a wider audit can uncover opportunities your current strategy is missing
If any of these sound familiar, choosing an SEO audit for business rather than another free tool scan is probably the right next move.
The different types of SEO audit (and which is right for you)
At Sherbet Donkey, we offer four levels of SEO audits, each built for a different stage of business and a different set of problems. Here's how to choose an SEO audit that actually fits what you need, whether that's a fast website SEO audit or a full enterprise-level review.
| Free SEO Audit | Free | 1 to 3 working days | A first look at where you stand |
| Starter Audit | £699 | 1 to 3 working days | SMEs needing an overall health check |
| Professional Audit | £1,599 | 3 to 5 working days | Growing companies who want to dig deeper |
| Expert Audit | £3,149 | 5 to 7 working days | Large, complex sites that need nothing missed |
Free SEO audit
Best suited to businesses who want a first look at where they stand, our free SEO audit gives you a snapshot of your current organic position, a breakdown of your keyword performance and a look at fresh keyword opportunities you might be missing. It's the ideal starting point if you're not sure yet how deep your problems run.
Starter audit, £699
Best suited to SMEs who need an overall website health check, the Starter audit covers your organic rankings, keyword performance, technical priority issues, on-page problems, site speed and a top-line look at your competitors, giving you a clear, honest picture of your site without a full enterprise-level dive.
Professional audit, £1,599
Best suited to growing companies who want to dig deeper, this includes everything in the Starter audit, plus a proper evaluation of your top 3 competitors, a meta titles and headings audit, a review of your backlink profile, a full sitemap check and an investigation into issues like duplicate content or keyword cannibalisation, along with short and long term strategy recommendations, not just a list of problems.
Expert audit, £3,149
Best suited to large, complex websites that need nothing left unchecked, this covers everything in the Starter and Professional audits, plus GA4 and Search Console analysis, an internal links audit, a full UX and UI review, troubleshooting for ranking or traffic loss, migration advice and ongoing strategy support, built for businesses where the stakes, and the site complexity, are higher.
How to avoid wasting money on the wrong audit
Choosing the right SEO audit isn't about picking the most expensive option and hoping it covers everything. It's about matching the depth of the audit to the size and complexity of your problem. A five-page brochure site with a handful of technical issues doesn't need an Expert audit, and a national ecommerce store with years of legacy content probably won't get what it needs from a free scan.
A genuinely professional SEO audit will always start with your goals, not a fixed package. If an agency pushes you towards their most expensive option before they've even looked at your site, that's worth questioning. Our SEO case studies show what that approach actually delivers when it's done properly. When you know how to choose an SEO audit properly, you match depth to complexity, not budget to ego, and that's how you avoid paying for work you don't actually need.
