How to Do a Website Audit: A Step-by-Step Guide for Business Owners

A website audit is a systematic review of your website to identify issues affecting its performance in search, its usability for visitors, and its ability to convert visitors into customers. It covers everything from technical SEO and page speed to content quality, design, and security.

Business owners often know their website could perform better but aren’t sure where to start. A structured audit gives you a prioritised list of improvements based on actual data rather than guesswork. This guide walks you through the key areas to review and the tools to use — no technical background required for most of it.

Technical and SEO health checks

Start with the technical foundation. Run your website through Google’s PageSpeed Insights (pagespeed.web.dev) to assess load speed on both mobile and desktop. Note your Core Web Vitals scores — Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and Interaction to Next Paint (INP). These affect both user experience and Google rankings. Address any issues flagged as “Poor” or “Needs improvement” before moving on.

Check Google Search Console for crawl errors, indexing issues, and manual actions. Under “Indexing > Pages”, review which pages are and aren’t indexed. Look at the Coverage report for errors and investigate any “Discovered but not indexed” or “Crawled but not indexed” warnings. Under “Experience”, check Core Web Vitals at page level. These reports give you Google’s actual view of your website, which is the most authoritative data source for SEO health.

Use a free crawl tool such as Screaming Frog (free for up to 500 URLs) to check for broken links (404 errors), redirect chains, missing or duplicate title tags, missing meta descriptions, images without alt text, and pages with very thin content. Export the results and sort by issue type — the most common problems on your site become immediately apparent.

Content and on-page SEO review

Audit your most important pages first: your homepage, your main service or product pages, and your top-performing blog content (identified in GA4 via Reports > Engagement > Pages and Screens). For each page, ask: does the title tag include the primary keyword? Is the H1 clear and descriptive? Is there enough content to genuinely help the visitor? Does the page have a clear call to action?

Compare your pages against what currently ranks on page one of Google for your target keywords. If your competitors’ pages are significantly longer, more detailed, or better structured, that’s a content gap to close. Tools like Semrush, Ahrefs, or the free version of Ubersuggest can help identify keyword opportunities your site isn’t currently ranking for.

Check your site for thin or duplicate content. Pages with fewer than 300 words rarely rank for anything competitive. Pages with very similar content to each other can dilute your rankings. Use canonical tags for intentional duplicates (such as product variants) and either expand or consolidate pages that are too thin to provide genuine value.

User experience, design, and conversion audit

Test your website on your phone. Navigate to your homepage, try to find a specific service or product, and attempt to contact the business. Note every moment of friction: text that’s too small, buttons that are hard to tap, menus that don’t work properly, or forms that are difficult to complete. Mobile experience affects both your SEO rankings and your ability to convert mobile visitors, who make up the majority of web traffic for most businesses.

Install Microsoft Clarity (free) or Hotjar (free tier available) to collect heatmaps and session recordings. After a week of data collection, watch recordings of real visitors using your site. You’ll see exactly where people get confused, where they abandon forms, and which content draws their attention. This qualitative data is often more revealing than quantitative metrics alone.
