How to Do a Website Audit

Most websites don’t fail loudly. Rankings slip a position at a time, organic sessions soften, and a quarter that should have grown comes in flat. By the time the dip shows up in revenue, it has usually been building for months. An audit is how you catch that early and find the actual cause behind it. As Semrush’s SEO team puts it, the smart way to think about one is as a “website health check.”¹

The work earns its place. Coalition Technologies has built more than 800 websites and generated over $588 million in organic search revenue for clients, and an audit is almost always where that work begins. It has to be. Roughly 35% of sites carry technical problems serious enough to keep search engines from crawling or indexing important pages,² which means a large slice of the web is leaking visibility nobody ever sees on a dashboard. Knowing how to do a website audit, even at a basic level, is the difference between reacting to a problem and watching it coming.

What an audit actually looks at

A website audit is a full read on how well a site can be found, crawled, used, and turned into revenue. People usually want to know what is included in a website audit before they start one, and the honest answer is that a thorough website SEO audit pulls several separate reviews into a single picture. It checks where the site ranks and how those rankings are trending. It looks at the technical plumbing underneath, the crawlability, indexing, load speed, and broken links that readers never notice but search engines punish. It weighs the content against what people are actually searching for. It inspects the metadata and images that decide how a page shows up in results. And it tests the mobile experience and the analytics that reveal whether any of this is converting.

None of those pieces means much in isolation. A fast site with thin content still loses. Great content trapped behind a crawl error never ranks. The point of doing the review all at once is to see how the pieces drag on each other, which is also why a partial check tends to miss the thing that actually matters.

Why rankings drop, and how an audit finds the reason

A sudden Google ranking drop feels random. It almost never is. The usual suspects are a migration that broke something, a content change that backfired, internal links that got orphaned in a redesign, or a core algorithm update landing while you weren’t looking. Paid campaigns slip for related reasons. When a landing page slows down or breaks, cost per click and cost per conversion climb across the whole account, and the media budget quietly stops working as hard.

Some declines aren’t about your site at all. They hit an entire industry at once. When Coalition Technologies compared client click-through rates before and after Google’s AI Overviews rolled out, the average dropped 35.89%, from 1.56% to 1.00%. A business looking only at its own traffic graph would read that as a failure and start tearing pages apart. An audit is what tells you whether you’re looking at an industry-wide shift or a problem you can actually fix, and that distinction saves a lot of wasted effort. If a decline is what brought you here, it’s worth reading this next to Coalition’s breakdown of recovering from a rankings drop and its primer on why a page isn’t ranking.

How to Do a Website Audit, Step by Step

The order below matters, because each stage leans on what the one before it turned up. Run it as a sequence, working down a website audit checklist from top to bottom, and the whole thing becomes repeatable instead of a scramble.

Start by benchmarking where you stand

Before you change anything, write down the current state. Search the products and services that matter most and note which pages show up, and on which page of results. Pull current organic sessions from Google Search Console and Google Analytics 4. This is dull and easy to skip, and skipping it is the most common reason an audit produces no measurable result later. Without a baseline, an SEO website audit has no before-and-after to point to.

Crawl the site for technical faults

A technical SEO audit runs the whole site through a crawler like Screaming Frog and cross-checks what it finds against Search Console. You’re hunting for the quiet stuff: broken links and redirect chains, duplicate pages eating crawl budget, orphaned pages nothing links to, and errors in the XML sitemap or robots file. Speed sits in this stage too, measured through Core Web Vitals, the three metrics Google watches for loading, responsiveness, and visual stability. It’s worth the attention. Sites that clear Google’s Core Web Vitals thresholds see a 24% lift in user engagement.³ When a site runs on heavy integrations or a custom build, Coalition Technologies handles this layer through a dedicated tech stack audit.

Read the content the way both a visitor and a crawler would

Content gets judged twice, once by the person reading it and once by the algorithm ranking it. Strong pages are clear, original, and obviously matched to the query that brought someone in. Check that your target keywords appear where they belong without tipping into the kind of over-optimization that reads as spam to Google. Thin or dated pages are usually the first things to rewrite or merge, and consolidating two weak pages into one good one often does more than polishing either alone.

Check the metadata and the images

Title tags and meta descriptions tell search engines what a page is about and decide whether a searcher actually clicks. Keep title tags close to 50 to 60 characters, lead with the term that matters, and never let two pages share the same one. Images are the piece most audits skim past, which is a mistake. Every image needs real alt text and a sensible file name, or it just adds weight to the page without earning any visibility in return.

Pressure-test the mobile experience

Mobile is where most of your traffic already lives. More than 60% of global web visits come from phones, and a single extra second of load time on mobile can cost up to a fifth of your conversions.⁴ Test the real thing on real devices, not a shrunk-down desktop preview, and pay attention to layout, tap targets, and speed. Coalition Technologies walks through the specifics in its guide on performing a mobile site audit, and its mobile SEO work picks up the deeper fixes.

Follow the money through analytics

Traffic that never converts is just spend with extra steps. Use Google Analytics 4 to see where visitors come from, where they bail, and which pages actually turn a session into a sale or a lead. Conversion gaps tend to expose design and copy problems that ranking data hides completely, and they’re often the fastest wins in the whole audit. Coalition Technologies routes those findings into ecommerce conversion rate optimization rather than letting them sit in a report.

Confirm you’re visible to AI

Search doesn’t run only through Google anymore. It runs through AI Overviews, ChatGPT, Perplexity, and a growing list of answer engines, and a current audit checks that their crawlers aren’t blocked and that your structured data gives them enough to understand and cite you. That visibility pays off even when nobody clicks. Search “what brand makes bucket hats,” and Coalition client Kangol takes the AI Overview spotlight, which keeps the brand in front of buyers who haven’t decided yet. Coalition Technologies digs into this in technical SEO for AI and how to optimize for AI search results.

An ecommerce audit and a small business audit aren’t the same job

Scope follows the kind of site you’re auditing. An ecommerce website audit carries problems a small lead-generation site simply doesn’t have: faceted navigation that spawns duplicate URLs, thousands of product and category pages competing for crawl budget, and checkout funnels where a single broken step costs real money. The work there leans heavily on indexing control and conversion paths.

A website audit for small business moves faster because there’s less of it. The work concentrates on speed, local visibility, and the handful of pages that bring in calls or form fills, with contact details and clear calls to action doing a lot of the heavy lifting. Coalition Technologies sizes the audit to the site rather than running every account through the same template, drawing on its small business web design guide and full ecommerce SEO work.

How often should you audit your website?

How often should you audit your website depends on how much it changes. For most active sites, a full audit once a quarter, with quick monthly spot-checks in between, keeps technical debt from piling up faster than you can clear it. The calendar isn’t the only trigger, though. Some moments demand an audit immediately: right before and right after a redesign or platform migration, in the days after a confirmed Google core update, and any time rankings, traffic, or ad performance take an unexplained dive. If you’re not sure whether you’ve hit one of those moments, Coalition Technologies lays out the signals in its guide on knowing when you need a technical audit.

When to hand it to someone who does this all day

You can learn how to do a website audit at a basic level yourself. Google Search Console and Analytics are free, and they’ll surface plenty on their own. Where it gets harder is depth and judgment, knowing which of the forty issues a crawler spits out actually moves rankings and which are noise, and what order to fix them in. That prioritization is most of the value professional SEO audit services add, and it’s the part the tools can’t do for you.

Coalition Technologies reports a 99% client satisfaction rate and 97% client retention across that work. If you’d rather see the upside first, its write-up on what a professional audit reveals is a good start, and its SEO team can take the whole thing off your plate. The audit is the easy part to understand and the hard part to act on, and acting on it is what moves rankings and revenue.
