SEO Audit Services for UK Websites
An SEO audit shows exactly what is stopping your website from ranking and what to fix first. NextMark checks your technical health, pages, content, links and competitors, then sends you a PDF report the same day with a prioritised list in plain English. Your first audit is free, with no obligation.
What We Check in an SEO Audit
A useful SEO audit looks at every reason a website might not rank, not just a technical score. These are the six areas we review.
Technical Health
Crawling and indexing, robots.txt and XML sitemap, broken links and redirects, duplicate pages, site speed and Core Web Vitals, mobile usability and HTTPS.
On-Page SEO and Content
Title tags, meta descriptions, headings, thin or duplicate content, keyword targeting, pages competing for the same search, internal links and image alt text.
Links and Authority
Who links to you, the quality and relevance of those links, broken backlinks you could recover, and how your link profile compares with competitors.
Local SEO and Business Profile
Your Google Business Profile, reviews, and whether your business name, address and phone number match across your website and directories.
Competitors and Keyword Gaps
Which competitors rank for the searches you want, what they do better, and keywords you could realistically win, including visibility in AI search.
Analytics and Conversions
If you share access, we check Google Analytics and Microsoft Clarity to see which pages bring enquiries or sales, and where visitors give up.
Free SEO Audit vs Follow-Up and Full SEO Audits
Most businesses start with the free audit. Standalone SEO audits from UK agencies often cost several hundred pounds or more. We start with a free one because it shows you what we find before you spend anything.
| Audit | What it covers | Format | Price |
|---|---|---|---|
| Free SEO audit | Your biggest problems and quickest wins across technical SEO, pages, links and local SEO | PDF report, same day | Free |
| Follow-up audit | A fresh check later on to measure progress or catch new problems | PDF report | £50 |
| Full SEO audit | Page-by-page technical and content audit with a detailed action plan | Part of ongoing SEO | Included in Growth (£300/month) |
What You Get in Your SEO Audit Report
- A prioritised fix list: every issue marked by its likely impact, so you know what to fix first.
- Plain English explanations: what each problem is, why it matters and how to fix it.
- Quick wins: changes that can be made in days, such as titles, broken links or indexing problems.
- Competitor and keyword notes: who ranks above you and which searches are realistic for your website.
- A clear next step: fix it yourself, pass it to your developer, or let us do it.
How We Carry Out an SEO Audit
We crawl your website with Screaming Frog, check your rankings, backlinks and competitors with Semrush, Ahrefs, Moz and Ubersuggest, and, with your permission, review your data in Google Search Console, Google Analytics and Microsoft Clarity. AI-assisted analysis helps us work through large amounts of data quickly.
Tools find issues, but they don't know which ones matter for your business. A tool might flag hundreds of warnings while missing that your most important service page is not indexed. That is why the report puts every finding in order of real impact on your rankings and enquiries.
Technical SEO Audit for Online Stores
Online stores need extra checks: filter and sort URLs, product variants, out-of-stock and discontinued products, Product structured data and crawl budget on large catalogues. If you run a Shopify, WooCommerce or Magento store, we include these in your audit. See our ecommerce SEO services.
When You Should Get an SEO Audit
- Your rankings or traffic have dropped and you don't know why.
- You are planning a redesign, a new platform or a domain change.
- Your website has never been checked by an SEO specialist.
- You are paying for SEO but cannot see what is being done.
- Competitors keep appearing above you for your main services.
After the Audit
The report is yours to keep, whatever you decide. You can fix the issues yourself, give the list to your developer, or ask us to do the work. Because NextMark also builds websites, we can fix most technical SEO problems directly. Ongoing SEO starts from £90 a month on a rolling plan with no long-term contract. Compare our SEO packages.
