A Slow Site Loses Customers and AI Citations

Google uses Core Web Vitals as a ranking factor. AI platforms deprioritize slow-loading sites. And 53% of mobile users abandon sites that take more than 3 seconds to load. Our Speed Audit identifies exactly what's slowing you down and the fastest path to fix it.

What is a Speed & Core Web Vitals Audit?

A speed and Core Web Vitals auditmeasures your website's real-world loading performance across Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS) — the three metrics Google uses as direct ranking signals. It identifies render-blocking resources, unoptimized images, slow server responses, and JavaScript bottlenecks, then provides a prioritized fix list to improve both user experience and search visibility.

Speed Is No Longer Optional — It's a Ranking Factor

Google confirmed that Core Web Vitalsare a direct ranking signal. AI platforms like ChatGPT, Perplexity, and Gemini favor fast-loading, well-structured sources when selecting content to cite. And your customers have already decided: if your site doesn't load in under 3 seconds, they're gone.

The sites that rank highest and get cited by AI aren't just well-written — they're fast. If your pages fail Core Web Vitals, you're leaving traffic, conversions, and AI visibility on the table.

The Performance Problem Hiding in Plain Sight

Real Finding: Unoptimized Images on Key Pages

From an actual Speed Audit

A service business was spending $3,000/month on Google Ads driving traffic to a landing page that took 7.2 secondsto load on mobile. Their bounce rate was 72%. They assumed the ads weren't working.

The real problem? Their hero image was a 4.5MB uncompressed PNG. Below the fold, they had 12 portfolio images served as full-resolution JPEGs with no lazy loading. The page was loading 28MB of images before the user could even scroll.

These weren't code problems. They were configuration problems — the kind a speed audit catches in minutes but that cost businesses months of wasted ad spend.

After converting to WebP, adding lazy loading, and implementing responsive sizing, load time dropped to 1.8 seconds — and their conversion rate doubled within two weeks.

What Your Speed Audit Covers

02.Page-by-Page Speed Analysis

Performance breakdown for your top 20 highest-traffic pages, not just a homepage-only test.

03.Image Optimization

Format analysis (WebP, AVIF opportunities), compression levels, lazy loading implementation, and responsive image sizing.

04.Render-Blocking Resources

JavaScript and CSS audit identifying scripts and stylesheets that delay page rendering.

05.Server & Caching Review

Server response times, CDN configuration, browser caching policies, and compression settings.

06.Projected Improvements

Before/after estimated scores showing the expected impact of each recommended fix.

Why AI Platforms Care About Your Site Speed

AI search engines like ChatGPT, Perplexity, and Google AI Overviews crawl and index web pages to generate answers. When their crawlers encounter a slow-loading page, they move on. Fast, well-structured sites get crawled more frequently, indexed more completely, and cited more often.

Faster Crawling

AI crawlers have time budgets. Faster pages mean more of your content gets indexed. Slow pages get partially crawled or skipped entirely.

Better Rendering

AI systems need to render your page to understand its content. Render-blocking resources and JavaScript-heavy pages often produce incomplete or empty content for AI crawlers.

Higher Citation Rates

Sites that pass Core Web Vitals and load quickly are more likely to be selected as sources by AI platforms. Speed is a trust signal for both users and machines.

Frequently Asked Questions About Speed Audits

Core Web Vitals are three specific metrics Google uses to measure user experience: LCP (Largest Contentful Paint) measures loading speed, CLS (Cumulative Layout Shift) measures visual stability, and INP (Interaction to Next Paint) measures responsiveness. Google uses these as ranking factors, and AI platforms also consider site performance when selecting sources to cite.

What feels fast to you on WiFi may be slow on a mobile connection. Google measures your site on mobile by default, and over 60% of web traffic is mobile. Many sites that score well on desktop fail Google's mobile performance thresholds. Our audit tests both and shows you the real numbers.

Speed fixes often show immediate results. Image optimization, caching changes, and render-blocking fixes can improve load times within hours of implementation. Most clients see measurable Core Web Vitals improvements within 1-2 weeks of implementing our recommendations.
