Web Audit
noun · technical analysis
A thorough and methodical analysis of a website covering technical performance, search engine optimization (SEO), security, and accessibility — aimed at identifying vulnerabilities, bottlenecks, and concrete improvement opportunities.
A professional evaluation process that scrutinizes the source code, server architecture, loading times, and compliance with web standards to provide an accurate diagnosis of a site's technical health along with prioritized recommendations.
A strategic step prior to any redesign or optimization that measures Core Web Vitals, analyzes internal linking, evaluates data security, and benchmarks performance against the competition — turning assumptions into informed decisions.
A website audit is a comprehensive technical analysis that evaluates the performance, SEO, security, accessibility, and usability of a website. It produces a detailed diagnosis with prioritized recommendations to improve every aspect. At Async Code, our audits cover over 200 checkpoints and rely on professional tools such as Lighthouse, GTmetrix, and manual source code reviews to deliver a concrete and measurable action plan.
A website audit is broken down into several phases: Core Web Vitals analysis (LCP, FID, CLS), technical crawling to detect indexing errors, internal linking and semantic structure audit, security testing, and accessibility evaluation. Each phase produces measurable indicators. Our agency Async Code uses a proven methodology combining automated tools and human expertise to identify high-impact optimizations for your performance and search rankings.
To test a website's performance, use tools such as Google Lighthouse, PageSpeed Insights, GTmetrix, and WebPageTest. These tools measure Core Web Vitals: LCP (loading time of the main content), FID (responsiveness to interactions), and CLS (visual stability). At Async Code, we go beyond these scores by analyzing the source code, asset optimization, caching strategy, and server architecture to identify bottlenecks invisible to automated tools.
An SEO audit is an in-depth analysis of all the factors that influence a website's ranking on search engines. It covers technical SEO (speed, indexing, markup), on-page SEO (content, keywords, semantic structure), and off-page SEO (backlinks, domain authority). Our agency Async Code performs comprehensive SEO audits that identify barriers to your visibility and provide a precise roadmap to sustainably improve your Google ranking.
A critical analysis of a website examines usability, visual consistency, content quality, technical performance, and the effectiveness of conversion paths. It cross-references quantitative data (analytics, heatmaps, Core Web Vitals) with a qualitative assessment of the user experience. At Async Code, we structure our critical analyses around our clients' business objectives to formulate actionable recommendations that generate measurable return on investment.
A web audit is a comprehensive examination of a website's technical and strategic health. It evaluates loading performance, code quality, security, SEO optimization, accessibility, and user experience. The deliverable is a detailed report with scores, screenshots, and prioritized recommendations. Our agency Async Code offers professional web audits that turn your site's weaknesses into concrete and measurable growth opportunities.
Auditing your website is essential to identify invisible problems that hinder your search rankings, slow down your site, and drive visitors away. An audit reveals technical errors (broken links, missing tags), security vulnerabilities, and untapped SEO optimization opportunities. At Async Code, our audits have helped clients improve their Lighthouse scores by 30 to 50 points on average, with a direct impact on their organic traffic and conversions.
A web marketing audit analyzes your entire digital presence: site performance, SEO strategy, advertising campaigns (SEA), social media presence, conversion rates, and user journeys. It cross-references this data to evaluate the ROI of each acquisition channel. Our agency Async Code complements the marketing analysis with a thorough technical audit, because code performance and infrastructure directly impact the effectiveness of your campaigns and your acquisition cost.
To carry out an effective website audit, start by measuring Core Web Vitals with Lighthouse, analyze indexing via Google Search Console, verify SSL security and HTTP headers, then evaluate accessibility with tools such as WAVE or axe. Combine these automated analyses with a manual code review and user experience assessment. At Async Code, we offer a comprehensive audit service that covers all these aspects and delivers a prioritized action plan tailored to your goals.
To detect website vulnerabilities, verify the validity of the SSL certificate, test HTTP security headers (CSP, HSTS, X-Frame-Options), look for XSS flaws and SQL injections, and analyze software dependencies for outdated versions. Tools such as OWASP ZAP and Mozilla Observatory automate some of these checks. At Async Code, our security audits identify critical vulnerabilities and provide immediate technical fixes to protect your data and that of your users.
