Short answer: how often should you do an SEO audit? Most small and medium UK businesses need a full SEO audit once a year, a lighter review every quarter and a quick health check every month. Larger or fast-changing websites, such as online shops, benefit from a full audit every six months. You should also run an audit straight away after a redesign, a website move or a sudden drop in traffic, whatever your normal schedule says.
This guide gives you a simple schedule, explains what to check at each level and lists the events that mean an audit cannot wait.
Why one audit is never enough
A website changes constantly. Pages are added or edited, plugins update, competitors improve and Google adjusts how it ranks results. Problems such as broken pages, slow loading or pages dropping out of Google’s index often build up quietly. Regular checks catch them while they are small and cheap to fix.
How often should you do an SEO audit? The 4-level schedule
| Level | How often | What it covers | Who usually does it |
|---|---|---|---|
| Health check | Monthly | Search Console errors, indexing, traffic and enquiry trends | You or your SEO provider |
| Quarterly review | Every 3 months | Key service pages, rankings for money keywords, Google Business Profile, reviews | Your SEO provider |
| Full SEO audit | Every 12 months (6 months for larger or ecommerce sites) | Technical health, content, internal links, backlinks, local SEO, competitors, tracking | An SEO specialist |
| Event-triggered audit | Whenever a major change happens | Whatever the change may have affected | An SEO specialist, quickly |
Monthly: a 15-minute health check
Open Google Search Console and look for new errors in the Pages report, a sudden fall in clicks or impressions, and any security or manual action warnings. Then check whether calls and enquiries from your website are steady. If you pay for monthly SEO, this should already be part of your report. See what happens during monthly SEO.
Quarterly: a focused review of what makes money
Every three months, look at the pages and searches that matter most to your business. Are your main service pages still ranking? Has a competitor overtaken you? Is your Google Business Profile up to date with recent reviews and photos? This is also a good time to refresh any page that has started to slip. Our guide on how monthly SEO work should be prioritised explains how to choose what to fix first.
Yearly: a full SEO audit
Once a year, have the whole website reviewed properly: technical health, every important page, internal links, backlinks, local signals, competitors and conversion tracking. For a breakdown of what this covers, read what an SEO audit includes or work through our SEO audit checklist.
How often should you do an SEO audit for your type of website?
- Small brochure or service website (under 30 pages): full audit once a year, monthly health checks.
- Local business with several services or areas: full audit once a year, quarterly reviews of service and location pages.
- Ecommerce store: full audit every six months, because product and category pages change often and technical issues spread quickly.
- Large or content-heavy website: full audit every six months, with monthly technical monitoring.
- New website: an audit at launch, then again after three to six months once Google has crawled it properly.
6 events that mean you need an SEO audit now
- A redesign or new website. Page addresses, content and structure often change, and rankings can drop if redirects are missed.
- Moving domain or changing platform. Migrations are one of the most common causes of lost traffic.
- A sudden fall in traffic or enquiries. Find the cause before it costs more business. Our guide on why a website is not ranking covers the usual suspects.
- A major Google update. If your traffic changes around the dates shown on the Google Search Status Dashboard, a review helps you understand why.
- Adding new services or locations. Check that new pages are set up correctly and do not compete with existing ones.
- Changing or reviewing your SEO agency. A neutral review shows what has been delivered. Read when to get an independent SEO audit.
Can you audit too often?
Yes. Running a full audit every month usually wastes time and money, because there is not enough change between audits to act on. Constant tweaking based on short-term ranking movements can also do more harm than good. The schedule above balances catching problems early with giving changes time to work.
Can you do an SEO audit yourself?
The monthly health check, yes. Search Console and your enquiry numbers are enough for most business owners. Quarterly and yearly audits need more experience, because the hard part is not finding issues but knowing which ones matter for your business and in what order to fix them. Free tools are a useful starting point but tend to list hundreds of warnings without priorities.
The bottom line
So, how often should you do an SEO audit? For most UK businesses: a quick health check every month, a focused review every quarter, a full audit once a year, and an immediate audit after any major change. If your last full review was more than a year ago, or you have recently redesigned your website, now is a good time.

Frequently asked questions
How long does an SEO audit take?
A full audit of a small business website usually takes a few days. Larger websites and online shops take longer because there are more pages and technical areas to review.
Is a monthly SEO report the same as an audit?
No. A monthly report tracks progress and the work completed. An audit is a deeper review of the whole website to find problems and opportunities. Good monthly SEO includes regular checks, but a full audit should still happen at least once a year.
Should I do an SEO audit after a Google update?
Only if your traffic or rankings changed noticeably around the update. If nothing moved, there is no need to react.
What should I fix first after an SEO audit?
Start with anything stopping important pages from being found or indexed, then improve your most valuable service pages, then work on links and content. Fixing issues in order of business impact matters more than fixing everything at once.
