Somewhere on your website is a blog post from 2021 about a service you no longer offer, ranking for nothing, read by nobody, and quietly dragging your average down. A content audit is how you find it. And the forty others like it.
A content audit is a structured review of everything you have published — every page, post and stray PDF — measured against what it is actually doing for you. You list it, you check how each piece performs, and then you make a call: keep it, improve it, merge it, or put it out of its misery. That last step is the part most people skip, which is precisely why most content audits end life as a spreadsheet nobody opens again.
The SEO industry loves an audit because it looks like work, produces an impressive document, and rarely commits anyone to anything. We are going to do the version that ends in decisions instead. It is less satisfying to look at and considerably more useful to own.
What a content audit actually is
At its simplest, a content audit answers three questions about every page you own: what is it, is it any good, and is it still pulling its weight. Get honest answers to those three and the decisions almost make themselves.
Where people come unstuck is treating "audit" as a single job. It is really two jobs wearing one coat, and doing them in the wrong order is how good pages get deleted by accident.
Inventory first, audit second
The distinction comes from the people who have been doing this longest. Nielsen Norman Group draws the line cleanly in its content inventory and auditing guide, and it is worth borrowing.
- The inventory is the full list. Every URL, title, type, author and publish date. It is a census, and a census does not have opinions. It just counts.
- The audit is the verdict. Each item on that list scored against how it performs, how accurate it still is, and how relevant it is to what you sell now. Opinions, but ones with evidence attached.
You cannot audit what you have not inventoried. Skip straight to opinions and you end up confidently binning the one ancient page that quietly earns a third of your enquiries. We have watched it happen. It is the website equivalent of throwing out the box your nan keeps the good biscuits in.
Why bother running one
Because content does not age like wine. It ages like milk, and the smell creeps up on you. A page that ranked nicely in 2023 can now be outdated, contradicted by a newer page of your own, or simply beaten by a competitor who updated theirs while you didn't. An audit catches all three before Google does it for you.
Done properly, a content audit gives you:
- A hit list of quick wins — pages sitting on the edge of page one that a refresh could nudge up, which is the cheapest traffic you will ever buy.
- The cannibalisation map — the spots where two of your own pages compete for the same query and split the vote, so you can merge them into one that actually wins.
- Permission to delete — clear evidence for cutting dead weight, so thin and irrelevant pages stop diluting how search engines judge the whole domain.
- A content plan grounded in reality — gaps you can prove are gaps, rather than topics someone fancied writing about on a Friday.
How to run a content audit, step by step
Here is the order that actually works. Follow it top to bottom and you will not get lost halfway through colour-coding a tab nobody asked for.
- Pick one goal. Organic traffic, conversions, or AI visibility. One. An audit chasing three goals at once produces a spreadsheet that recommends everything and decides nothing.
- Build the inventory. Crawl the whole site to pull every URL, title, meta description and word count into one sheet. A crawler does in ten minutes what would take you a tragic afternoon of copy-pasting.
- Pull the numbers for each page. Bolt on the data that matters to your goal — sessions and engagement from GA4, clicks and impressions from Search Console, plus current ranking position for the keyword each page targets.
- Score every page against the goal. Rate each one honestly. High performers, near-misses worth a push, the walking dead, and the genuinely confusing pages that target nothing in particular.
- Decide the fate of each page. Keep, update, consolidate, or cull. This is the whole point of the exercise, so do not lose your nerve here and label everything "review later."
- Write the action list. Every verdict becomes a task with an owner and a date. "Update the pricing page" with nobody attached and no deadline is not an action. It is a wish.
Start with a free Search Console export before you pay for anything. The Search Console performance report already tells you which pages get clicks, which get impressions but no clicks, and which Google has quietly stopped showing. That is half your audit, free, sitting in a tab you already have open.
Keep, update, consolidate, or cull
Every page in the audit lands in one of four buckets. Resist the urge to invent a fifth one called "maybe." Maybe is where audits go to die.
| Verdict | When it applies | What you do |
|---|---|---|
| Keep | Performs well, accurate, still relevant | Leave it alone. Note the next review date and move on. |
| Update | Good bones, dated facts, slipping rankings | Refresh the content, tighten the structure, republish, request reindexing. |
| Consolidate | Two or more thin pages targeting the same intent | Merge into one strong page and 301-redirect the losers into it. |
| Cull | No traffic, no links, no relevance, no future | Redirect it to the closest relevant page, or remove and let it 410. |
Most owners over-index on "keep" because deleting your own writing feels like deleting a memory. It isn't. A lean site of pages that all earn their place beats a sprawling one where the good stuff is buried under archived event pages from 2022. Pruning is growth. Gardeners worked this out centuries ago.
Audit for AI search, not just Google
Here is the part most content-audit guides were written too early to mention. Checking your blue-link rankings is no longer the whole job. A page-one Google ranking is no longer sufficient on its own — 25.11% of Google searches now trigger an AI Overview, up 57% in a single quarter according to Conductor's 2026 benchmarks. If your audit only asks "does this rank," it is auditing for a search results page that fewer people see every month.
So add a second column to the verdict. Alongside "does this rank," ask "could an AI lift this." For each important page, check:
- Does it answer the question in the opening lines? AI models quote the first 40 to 60 words of a section. Bury the answer in paragraph six and you have written it for nobody.
- Are the claims specific and quotable? A page full of "significantly improves results" gives a model nothing to cite. A page with a number, a date and a named source gives it something to lift verbatim.
- Is it structured for a machine? Clean headings, tidy tables, and schema markup. Google's structured data documentation covers the implementation, and it is the difference between a page an AI can parse and one it skims past.
If that side of the audit turns up mostly blanks, you are not failing — you are just looking at the next six months of work. Our guide to making your site impossible for AI to ignore walks through the fixes in order.
The tools you actually need
You can spend a fortune here. You do not need to, and anyone telling you otherwise is usually selling the fortune.
- A crawler to build the inventory — Screaming Frog is free up to 500 URLs, which covers most small business sites with room to spare.
- Google Search Console for clicks, impressions and queries. Free, and the single most honest source of data you have about your own pages.
- Google Analytics 4 for what people do once they land — engagement, conversions, and whether the page leads anywhere useful.
- One spreadsheet to pull it together. Yes, really. The expensive all-in-one platforms are lovely once you are at scale, but the work is the same and the spreadsheet does not bill you monthly.
The tool does not do the audit. You do. A £400-a-month platform pointed at a site by someone who will not make the hard calls produces a more expensive version of the same spreadsheet nobody opens.
When a content audit is a waste of money
Now the bit most agencies skip, because it talks us out of work. Sometimes you do not need an audit. If your whole site is twelve pages, you do not have a content problem to audit — you have a content shortage to fix. Auditing twelve pages is like doing a stock-take of an empty shop. Go and write the content first, then audit it in a year.
We picked up a business last year that had paid a previous agency £1,200 a month for fourteen months. The entire content output: three blog posts, all spun from the same template, none linked to from anywhere else on the site, none touched since publication. A proper content audit would have flagged all three in an afternoon — but there was nothing to audit, because there was barely anything there. They did not need a forensic review. They needed someone to actually publish things worth reviewing.
So if a content audit is genuinely the right move, our AI SEO service builds it into the first month of work, with pricing on the website and no contracts to escape later. And if it isn't the right move yet, we will tell you that on a call, for free, and then decline to take your money until it is. (Yes, we are aware that is a strange way to run a business. No, we are not changing it.) Want a quick read on where you stand first? A free SEO and AI audit will tell you which of your pages are working and which are just taking up space.
Frequently asked questions
How long does a content audit take?
For a small business site of fifty to a hundred pages, building the inventory takes an afternoon and the scoring takes another day or two of focused work. A large site with thousands of URLs is a multi-week project. The crawl is fast either way — the time goes into the honest judgement on each page, which is the part you cannot rush or automate away entirely.
How often should you run a content audit?
A full audit once a year is plenty for most businesses, with a lighter check every quarter on your most important pages. If you publish heavily or operate in a fast-moving market, lean towards more frequent reviews. The trigger to do one sooner is a traffic drop you cannot explain — that is usually old content quietly losing ground, and an audit finds it.
What is the difference between a content inventory and a content audit?
The inventory is the list of everything you have published — URLs, titles, types, dates — with no judgement attached. The audit is the evaluation of that list, scoring each item on performance, accuracy and relevance, then deciding what to do with it. You build the inventory first, then audit against it. One counts; the other decides.
What tools do I need for a content audit?
A crawler to gather the inventory, Google Search Console and Google Analytics 4 for the performance data, and a spreadsheet to bring it together. That stack is free or close to it and handles most small and mid-sized sites. Paid platforms speed things up at scale, but they do not change the method and you do not need one to start.
Can I use AI to do a content audit?
AI is genuinely useful for parts of it — summarising pages, spotting topic overlap, drafting refresh briefs, and flagging outdated phrasing at speed. What it cannot do is make the final call with your business context in mind, because it does not know which old page secretly drives your phone calls. Use it to accelerate the grunt work, not to replace the judgement.
Should I delete old content or update it?
Update it when the page has good bones — relevant topic, some links or rankings, just dated facts or thin structure. Delete or redirect it when there is no traffic, no links, and no relevance to what you sell now. When two pages target the same intent, merge them into one and redirect the rest. Deleting genuinely dead pages helps the site; deleting a quiet performer hurts it, which is exactly why you audit before you cut.
Does a content audit help with AI search visibility?
It does, if you build it into the brief. Alongside checking rankings, score each page on whether an AI could lift a clean answer from it — a direct opening, specific and quotable claims, and proper structure with schema. Optimised pages tend to start showing up in AI answers within four to eight weeks of being indexed, so an audit is often the fastest way to find which existing pages are nearly there already.
Run the inventory, score the pages, make the calls, and your content stops being a graveyard and starts being an asset. If you would rather not spend your weekend colour-coding a spreadsheet, that is what we are for — and we will probably flag something mildly alarming about your old service pages while we are in there. Consider it a bonus. Get in touch and we will tell you, honestly, whether an audit is worth doing yet.
