Every audit begins with an overarching review of the website, assessing page speed scores and performance across all content.
While this stage varies depending on the website’s layout, it should flag slow loading speeds and other Core Web Vitals.
An excellent tool for this stage is Google PageSpeed Insights, which performs instant scans of URLs added to the system.

Once the site-wide analysis is finalized, on-page search engine optimization is used to highlight ways to improve keyword rankings.
Search engine optimization is vital for all online businesses, and many website builders incorporate SEO audit tools into their platforms.
Body text, meta descriptions, and alt tags are all checked via an on-page SEO audit, with AI tools available for optimization.
Once the check is complete, you can conduct new keyword research to address mismatches or overstuffing in your web pages.
Auditing content extends beyond SEO and also covers an assessment of the content quality and relevance to visitors.
Out-of-date information, issues with blog formatting, and the use of poor-quality visual assets must all be addressed during a site audit.
The process is also used to identify how your content ranks against competitors for specific keywords and what new material to consider.
Tools like Ahrefs can help, while Google Analytics remains a powerful tool for evaluating which content delivers the best engagement.
A technical website audit evaluates the site and key pages for issues of concern, including 404 page errors and non-indexed pages.
These fixes are vital for improving a website’s ranking performance, ensuring page content is included in search engine results.
Built-in technical SEO audit tools featured in website builders streamline this stage, handling errors in bulk and creating indexed pages for Google.
The process allows for the removal of low-value pages that might be impacting visibility, as well as broken visual assets.
It can also flag the absence of an XML sitemap, which is necessary for helping search engines discover your content.
Updating a site’s performance on the backend and improving SEO flows into the overall user experience when visiting the site.
These processes are augmented with a general approach to testing the user experience and deciding how to improve navigation and functionality.
The site’s structure and features should be intuitive, and information should be presented clearly through the site’s design.
A UX audit should draw on user feedback, since this can quickly highlight weaknesses and common pain points.
Website audits should also evaluate overall accessibility, ensuring content is understandable to all types of visitors.
Accessibility testing includes checking for WCAG compliance, screen reader compatibility, and color contrast to improve legibility.
Websites must also be accessible and functional on different devices, working as intended on mobile devices.
Since Google uses mobile-first indexing, understanding the core features of mobile website design is crucial for visibility.
Performing audits is an iterative process, with data collection and analysis at the heart of improving results.
It includes evaluating any previously established key performance metrics, such as conversion rates and pages per session.
For e-commerce websites, this can also include analysis of sales data and how it aligns with search engine optimization.
You can extend this stage to incorporate auditing your inventory of analytics tools and developing a consistent implementation approach.
Website security is crucial for identifying vulnerabilities that could lead to the loss of customer data and other sensitive personal information.
When auditing a site, security measures, such as SSL and TLS certificates, should be updated and maintained.
This stage also involves assessing the effectiveness of firewalls, correctly configuring security headers, and maintaining site backups.
If necessary, stricter access control may be required to ensure role-based permissions and prevent accidental changes.
Likewise, two-factor authentication should be applied to all site users, particularly at the administrative level.
Lastly, a comprehensive audit requires competitor analysis, using the sites of other businesses as benchmarks for performance.
By assessing how competitors design a website, future improvements and new features can be planned effectively.
Factors to look out for include whether the site is mobile-friendly and how visually appealing its design elements are.
Exploring competitor sites will provide insights into the overall user experience and how it links to a social media presence.
Throughout the competitor analysis, note any comparative weaknesses your site has and the steps you can take to address them.
You can also use Google Analytics and other tools to check their performance and use this data for additional benchmarking.
