SEO rankings are lost
in milliseconds.
Google's algorithm doesn't just care about your keywords. It cares about your Core Web Vitals. Stop guessing why your rankings are slipping and start monitoring the technical regressions that cause them.
Google is watching your LCP.
A single unoptimized image or a heavy tracking script can push your Largest Contentful Paint (LCP) over the 2.5s threshold. In the eyes of Google, your site is now "Poor." Rankings drop. Traffic evaporates.

Frequently asked questions
What does a free SEO checker analyze?
AuditJet's free SEO checker runs a Lighthouse-powered audit on any URL and returns: Lighthouse performance score, Core Web Vitals (LCP, INP, CLS), Time to First Byte (TTFB), First Contentful Paint (FCP), and a breakdown of specific issues affecting each metric. The audit completes in under 60 seconds and requires no account.
Is a free website SEO check accurate?
AuditJet's checker runs real Lighthouse tests against your live URL — the same engine Google Search Console and PageSpeed Insights use. Lab scores can vary slightly between runs due to server load, but they are accurate representations of your page's performance under normal conditions. For field data (real user performance), upgrade to continuous monitoring which collects CrUX and RUM data.
How do I improve my website SEO score?
Focus on the three Core Web Vitals first: reduce LCP by optimizing your hero image (add fetchpriority='high' and use WebP), improve INP by reducing long JavaScript tasks, and fix CLS by setting explicit width/height on all images and avoiding injected content above the fold. These three metrics are direct Google ranking signals. AuditJet's audit report includes specific fix recommendations for each failing metric.
How often should I check my website's SEO performance?
Run a one-off check after major deploys or design changes. For ongoing protection, set up continuous monitoring — AuditJet's monitoring plans scan your key pages hourly and alert your team when Core Web Vitals regress, so you catch issues within hours rather than discovering them through traffic drops days later.
Does the SEO checker work on pages behind a login?
AuditJet's SEO checker tests publicly accessible URLs the same way a search engine crawler would. Pages that require authentication — login walls, cookie-gated content, or IP-restricted staging environments — cannot be reached by the scanner and will return an error. For authenticated page monitoring, AuditJet's continuous monitoring plans support custom headers and cookie injection so your team can track protected routes.
How is AuditJet's SEO check different from Google Search Console?
Google Search Console reports field data — aggregate performance measured across real users over a 28-day window, which means regressions appear days or weeks after they occur. AuditJet runs synthetic lab tests on demand and on a continuous schedule, catching regressions within minutes of a deploy. AuditJet also provides AI-generated fix blueprints and revenue impact estimates that Search Console does not offer.
What's the fastest fix for a failing Core Web Vitals SEO score?
The single highest-leverage fix for most sites is the LCP image. Add fetchpriority='high' to your hero image element, convert it to WebP or AVIF, and ensure it is not lazy-loaded. This alone moves LCP below the 2.5s threshold on the majority of pages that fail. After running an AuditJet check, the report highlights whether your LCP element is an image, a block of text, or a video poster, and tailors the fix recommendation accordingly.
Can I run an SEO check on a competitor's site?
Yes. AuditJet's SEO checker accepts any public URL, including competitor pages. Many teams run checks on their top three competitors before and after major product launches to benchmark Core Web Vitals side by side. AuditJet's continuous monitoring plans include built-in competitor benchmarking that tracks rival sites on the same schedule as your own pages.
