How to do an SEO audit in 2026 (the step-by-step we run for clients)
An SEO audit finds exactly what's holding your rankings back — and what to fix first. Here's the practical, prioritised process our team runs, from crawlability and speed to content, authority and the page-two quick wins.
An SEO audit is a structured review of your website that finds the issues holding back your rankings and tells you what to fix first. A good one checks crawlability and indexing, speed and page experience, on-page optimisation and content, keyword overlaps, and your backlink profile — then turns the findings into a prioritised action plan. It's the first thing we run for any new SEO client, because you can't fix what you haven't measured.
You can do a capable audit yourself with free tools and a clear method. Here's the step-by-step process our team follows, in the order that gets results fastest.
An audit isn't a list of everything wrong — it's a ranked list of what to fix first. Crawlability before content, site-wide fixes before page-by-page, and the page-two quick wins before the long shots.
What an SEO audit is (and why it matters)
Search engines constantly update their algorithms, so a strategy that worked last year can quietly slip. An audit exposes the weaknesses in your site — broken links, slow pages, thin content, indexing problems — and shows where to make changes. Skip it and you're optimising blind.
The output that matters is a plan of action: not just "here's what's wrong" but "here's what to fix, in what order, for the biggest gain". That prioritisation is the difference between an audit that sits in a drawer and one that lifts rankings.
1. Check crawlability and indexing first
Start here, because if Google can't crawl and index your pages, nothing else matters — they simply can't rank. Run a crawl with a tool like Screaming Frog, Ahrefs or Semrush to surface anything blocking access, then check indexability separately to see what Google can actually store.
- ✓ Crawl the site and flag broken links, redirect chains, blocked resources and orphaned pages.
- ✓ Check Google Search Console's index coverage to see which pages are indexed and which are excluded, and why.
- ✓ Confirm your robots.txt and sitemap aren't accidentally hiding pages you want ranked.
- ✓ Fix indexing blockers as a priority — they're the highest-leverage issues you'll find.
If publishing fresh content isn't getting picked up, this is usually why — our guide to getting pages indexed goes deeper.
2. Assess speed and page experience
Page speed and user experience are among the top ranking factors, and Google has confirmed it. A slow site or a frustrating mobile experience drags rankings and drives visitors away before they convert. The bonus: speed and experience fixes are usually site-wide, so one change lifts every page.
- Run Google PageSpeed Insights to find what's slowing pages on mobile and desktop, and follow its fixes — compress images, trim heavy code, leverage caching.
- Test mobile-friendliness. Most traffic is mobile and Google indexes the mobile version of your site, so responsive design is non-negotiable.
- Check core page-experience signals — loading, interactivity and visual stability — since they feed directly into rankings.
3. Review on-page optimisation and content
Next, check that each page tells Google clearly what it's about, and that the content genuinely deserves to rank. On-page is where many sites leave easy gains on the table.
- Title tags — descriptive, keyword-rich and the right length, since they appear in the results and signal relevance.
- Meta descriptions — unique and compelling for every page; they don't rank you directly but they win the click.
- Headings and structure — a clear H1 with the target keyword, logical subheadings, short paragraphs and lists.
- Keyword placement — your target term in the title, H1, opening sentence and naturally through the copy, without stuffing.
- Content quality and uniqueness — Google wants genuinely useful, original content. Study what's ranking and make yours more complete and current. Our on-page SEO checklist is the detailed companion here.
4. Find the quick wins and fix cannibalisation
Two checks here deliver outsized returns for little effort:
- ✓ Prioritise low-hanging fruit. Keywords you already rank for in positions 3–15 are your fastest wins — they're already working and a few tweaks (internal links, refreshed copy, better meta tags) can push them onto page one. Find them in Search Console or Ahrefs.
- ✓ Fix keyword cannibalisation. When two or more pages target the same keyword, they confuse Google and dilute each other. Identify the overlaps, then merge the content or re-focus one page. As a rule, keep the page with the most traffic and authority — Google prefers a few strong pages over many weak ones.
"The fastest gains in any audit aren't new pages — they're the page-two rankings you already own. Push those up before you chase anything new.

5. Assess authority and backlinks
Finally, review your backlink profile, since authority is a major ranking factor. Look at your total number of unique referring domains — it should grow over time to keep Google viewing you as increasingly trustworthy. Then judge the links you have on three things:
- Relevance — links from sites related to your topic carry far more weight than unrelated ones.
- Authority — links from high-authority sites help; links from spammy, low-quality sites can actively hurt you.
- Traffic — a link from a site that gets real organic traffic signals genuine quality.
Flag and disavow toxic links, and note the gap between your profile and your competitors' as your link-building roadmap.

How often should you audit?
An audit isn't a one-off. We recommend a full audit at least quarterly, plus a check whenever there's a major Google algorithm update. Search intent, competition and the algorithm all shift, so regular audits keep your site current rather than letting issues accumulate. If you bring in a freelancer or agency, give them full access — including the back end and analytics — and make sure they deliver a clear plan of action, not just a list of problems.
Audit myths to ignore
- "SEO is all about ranking number one." Chasing position alone ignores valuable traffic further down and tempts black-hat shortcuts. Optimise for conversions, not just rank.
- "More keywords is better." Stuffing keywords hurts readability and can trigger a penalty.
- "SEO has to be expensive." A capable audit runs on free tools — the method matters more than the spend.
- "It's a one-time job." SEO is ongoing; so is auditing.
Run the audit in this order, act on the priorities, and you'll fix the issues that actually move rankings — rather than tinkering at the edges. Patience matters too: changes take time for Google to register, but the compounding is worth it.
Frequently asked questions
What is an SEO audit?
An SEO audit is a structured review of your website that identifies the issues holding back your rankings and prioritises what to fix first. It checks crawlability and indexing, speed and page experience, on-page optimisation and content, keyword overlaps, and your backlink profile, then turns the findings into a clear action plan.
How do I do an SEO audit myself?
Work in order: check crawlability and indexing in Google Search Console and a crawler like Screaming Frog, assess speed with PageSpeed Insights, review on-page elements and content quality, find page-two quick wins and fix keyword cannibalisation, then evaluate your backlink profile. Prioritise indexing blockers and site-wide fixes first.
What are the fastest SEO wins in an audit?
Keywords you already rank for in positions 3–15 are the fastest wins — they're already working, so small tweaks like internal links, refreshed copy or better meta tags can push them onto page one. Fixing keyword cannibalisation, where multiple pages compete for the same term, also delivers quick gains.
How often should you do an SEO audit?
Run a full SEO audit at least quarterly, plus a check whenever there's a major Google algorithm update. Search intent, competition and the algorithm shift over time, so regular audits keep your site current and catch issues before they accumulate, rather than letting small problems compound into ranking losses.
Do I need to pay for tools to audit my site?
No. A capable SEO audit can run entirely on free tools — Google Search Console, Google Analytics, PageSpeed Insights and Screaming Frog (free up to 500 URLs). Paid platforms like Ahrefs or Semrush add depth for keyword difficulty and backlink analysis, but the method matters far more than the spend.
