What Our Free Website Audit Checks
Every site audit runs through Google's own Lighthouse engine, the same technology behind Chrome DevTools and Google Search Console. Your site is tested against four critical categories that directly impact search rankings and user experience.
Performance Score
Measures how fast your pages load and become interactive. Evaluates Core Web Vitals including Largest Contentful Paint (LCP), Total Blocking Time (TBT), and Cumulative Layout Shift (CLS). Slow sites lose visitors and rankings.
SEO Score
Checks whether your page follows SEO best practices that help search engines discover and rank your content. Validates meta tags, heading hierarchy, canonical URLs, structured data, mobile friendliness, and crawlability.
Accessibility Score
Evaluates how usable your site is for people with disabilities. Tests ARIA labels, color contrast, keyboard navigation, alt text, and semantic HTML. Accessibility issues also signal poor quality to search engines.
Best Practices Score
Audits your site for modern web standards including HTTPS security, image optimization, JavaScript errors, deprecated APIs, and browser compatibility. These factors affect both user trust and search engine confidence.
Why Page Speed Directly Affects Your Revenue
Site speed is not just a technical metric. It is a direct driver of revenue, conversions, and customer acquisition. Every fraction of a second counts, and the data proves it.
The Compounding Cost of a Slow Website
When your site loads slowly, the damage compounds across every stage of your funnel. Search engines rank you lower, so fewer people find you. Of those who do click, more than half leave before the page even finishes loading. The visitors who stay convert at lower rates because slow experiences erode trust. You end up paying more for ads, generating fewer leads, and leaving significant revenue on the table — all because of a performance problem most businesses don't even know they have.
A one-second improvement in load time can increase conversions by up to 27%. For a business generating $100,000 per month in online revenue, that single second could mean an additional $27,000 every month — $324,000 per year — from the same traffic you already have.
Core Web Vitals: The SEO Metrics That Matter Most
Google uses Core Web Vitals as a ranking signal. These three metrics measure real user experience and directly influence where your site appears in search results.
Measures how long it takes for the largest visible element on your page to render. This is the best proxy for perceived load speed. Your LCP should be under 2.5 seconds.
Measures the responsiveness of your page to user interactions like clicks, taps, and key presses. A low INP means your site feels fast and responsive. Target under 200 milliseconds.
Measures visual stability — how much your page layout shifts while loading. Unexpected layout shifts frustrate users and damage trust. Keep your CLS under 0.1.
How Regular Site Audits Drive Business Growth
An site audit is not a one-time task. The most successful businesses treat website audits as an ongoing process that compounds results over time.
Catch Technical Issues Before They Cost You Rankings
Broken links, crawl errors, missing meta tags, and slow-loading pages silently erode your search visibility. A regular site audit catches these issues early, before they snowball into ranking drops. Sites that run monthly audits recover from technical issues 3x faster than those that don't.
Convert More of the Traffic You Already Have
Most businesses focus on getting more traffic when they should be converting the traffic they already have. Performance optimization alone can increase conversion rates by 15-30%. Fixing accessibility issues opens your site to a wider audience. Resolving best practice violations builds user trust. An site audit identifies every opportunity to turn existing visitors into paying customers.
Stay Ahead of Google Algorithm Updates
Google updates its algorithm thousands of times per year. Core updates can shift rankings overnight. Regular audits ensure your site stays aligned with the latest ranking factors, including Core Web Vitals, mobile usability, HTTPS security, and structured data requirements. The businesses that monitor and adapt proactively are the ones that survive algorithm changes.
Build a Data-Driven SEO Strategy
Audit data over time reveals patterns. You can see which optimizations moved the needle, identify recurring issues, and prioritize your SEO budget based on measurable impact rather than guesswork. This data-driven approach consistently outperforms ad hoc SEO work by delivering higher ROI and sustainable organic growth.
What Makes a Good SEO Score?
Understanding what your site audit scores mean is critical to making the right improvements. Here is how to interpret results from any website audit tool.
90 - 100: Excellent
Your site meets or exceeds Google's standards. Pages in this range load quickly, follow SEO best practices, and provide a strong user experience. Sites scoring 90+ across all categories typically rank in top positions for their target keywords and see significantly higher conversion rates.
50 - 89: Needs Improvement
Your site has issues that are actively holding back your search performance. Common problems in this range include unoptimized images, render-blocking resources, missing meta descriptions, and slow server response times. Most sites fall into this category, which means fixing these issues gives you a competitive advantage.
0 - 49: Poor
Significant problems are damaging your search visibility and driving visitors away. Sites in this range often have major performance bottlenecks, critical SEO errors, or serious accessibility failures. Immediate action is needed to prevent further ranking losses and revenue decline.
Frequently Asked Questions
Everything you need to know about our free site audit tool and website performance analysis.
What does this free site audit tool check?
Our free site audit tool uses Google's PageSpeed Insights API to analyze four key categories: Performance (page speed, Core Web Vitals like LCP, TBT, and CLS), SEO (meta tags, crawlability, structured data), Accessibility (ARIA labels, contrast, keyboard navigation), and Best Practices (HTTPS, image formats, JavaScript errors). You get a score from 0-100 for each category plus specific issues to fix, prioritized by impact.
How accurate is this free website audit?
Very accurate. Our tool runs Google Lighthouse directly through the official PageSpeed Insights API — the same engine used by Chrome DevTools and Google Search Console. The results reflect exactly how Google evaluates your website. Unlike some free SEO checkers that use proprietary scoring, our results come straight from Google's own testing infrastructure.
Do I need to sign up or pay anything?
No. This site audit tool is completely free with no signup, no email gate, and no credit card required. Enter any URL and get your full audit results in seconds. Run as many audits as you want — there are no limits on usage.
How does page speed affect SEO rankings?
Page speed is a confirmed Google ranking factor. Core Web Vitals (LCP, INP, CLS) directly impact search rankings as part of Google's Page Experience signals. Research shows that 53% of mobile visitors abandon sites that take longer than 3 seconds to load, and a 1-second delay in page load time can reduce conversions by 7%. Faster sites rank higher, convert better, and generate more revenue.
What is a good site audit score?
Scores of 90-100 are considered excellent (green), 50-89 need improvement (orange), and 0-49 are poor (red). We recommend aiming for 90+ across all four categories. Sites scoring 90+ in Performance typically see better rankings, lower bounce rates, and significantly higher conversion rates compared to slower competitors.
How often should I run an site audit?
We recommend running a full site audit at least once per month, and after any significant website changes like redesigns, plugin updates, or content migrations. Regular audits help catch issues before they impact your search rankings and traffic. Set a recurring calendar reminder to audit your site on the first of every month.
Why does my score change between audit runs?
Slight variations between runs are normal. Lighthouse tests simulate real-world conditions including network throttling, device emulation, and server response times — all of which can vary slightly. Differences of 3-5 points between runs are expected. Focus on the overall trend rather than any single score. If your Performance score is consistently below 90, optimization work is needed.
What should I fix first after running an audit?
Start with the issues that have the highest estimated savings. Our audit results prioritize issues by severity — the worst problems appear first. Common high-impact fixes include compressing and properly sizing images, eliminating render-blocking resources, implementing text compression, and fixing missing meta descriptions. Even fixing 2-3 top issues can improve your scores dramatically.
