Review Website Performance and Core Web Vitals
Find slow templates, high TTFB values, heavy resources, render-blocking assets, JavaScript load, image problems, and CLS risks before slowing down rankings, crawling, and conversion.
Performance is a quality, SEO and sales signal
Core Web Vitals combine technical loading time with user experience. When server responses, JavaScript, images or layouts slow down, not only does the Lighthouse score suffer, but often also crawl efficiency and conversion.
The hub bundles a monetizable audit, free performance tools and connection content for search queries around loading time, pagespeed, LCP, INP, CLS, TTFB and website speed optimization.

Where Core-Web-Vitals Problems Arise on Websites
Many performance problems do not sit on a single URL, but in reused templates, global scripts, tracking containers, image components or server caching rules. The audit makes these patterns visible.
Backend, database, CDN, caching and redirects determine how fast the browser gets HTML at all.
Hero images, critical CSS, fonts, and preload strategies affect the main visible content.
Framework bundles, tracking tags and widgets can significantly delay interaction.
Images, iFrames, ad space and fonts need reserved space and stable fallbacks.
Too large images, missing lazy loading and incorrect formats are particularly slowing down mobile users.
Analytics, Ads, Chat, A/B Testing and Embeds generate additional requests and main thread work.

Open Core Web Vitals AuditFrequent Questions about Website Performance
Are Core Web Vitals a Ranking Factor?
Core Web Vitals are among the page experience signals. For SEO, they are particularly relevant if content is comparable or performance significantly affects usability and conversion.
Why isn’t a single Lighthouse test enough?
A single test shows a URL in a situation. Many websites have different templates. A crawl reveals patterns that are different on the homepage, categories, products, or forms.
Which metric should be optimized first?
When TTFB is high, first server and caching. When JS dominates, INP and Main Thread. If images or layouts stand out, prioritize LCP and CLS.
Does performance fit SEO audits?
Yes. Performance affects user experience, crawl efficiency, technical quality and conversion. This is why the performance audit complements the existing SEO audit.
