What Is a Technical SEO Audit?
A technical SEO audit is a comprehensive health check of your website's underlying code, server setup, and architecture. Unlike on-page SEO, a technical analysis ensures search engine bots can successfully crawl, render, and index your pages.
If Google cannot easily read your HTML or your site fails the Core Web Vitals assessment, your rankings will suffer — regardless of how many backlinks you build or how much AI content you produce.

What Does Your SEO Score Mean?
Your performance score is calculated by Google Lighthouse — the same engine powering Google PageSpeed Insights. It combines Core Web Vitals and dozens of technical audits into a single 0–100 number. Here's how to interpret your grade:
A
90–100
Top-tier performance. Strong ranking advantage. Passes all Core Web Vitals.
B
80–89
Good performance. Minor issues remain. Small fixes to reach A-tier.
C
60–79
Needs improvement. Sites here typically rank on pages 2–4 in Google.
D
40–59
Poor performance. Significant ranking disadvantage. Requires immediate action.
F
0–39
Critical issues. Google actively deprioritizes sites with scores below 40.
Industry Score Benchmarks
Most websites score far lower than people expect. Here are typical average mobile PageSpeed scores by industry, based on Google's own data:
| Industry | Avg Mobile Score | Avg Desktop Score | Key Challenge |
|---|---|---|---|
| 🛒 Ecommerce | 28–42 | 52–65 | Heavy product images, third-party scripts |
| 📰 News / Media | 30–45 | 55–70 | Ad scripts, large images, render blocking |
| ✍️ Blogs / Content | 55–72 | 75–88 | Theme overhead, unused CSS/JS plugins |
| 💼 B2B / SaaS | 48–65 | 68–82 | Marketing scripts, large hero images |
| 🏥 Healthcare / Local | 35–52 | 55–72 | Outdated CMS, no image optimization |
If your score is above the average for your industry, you already have a technical SEO edge over your competitors. Use this tool to push even higher.
KNOWLEDGE BASE
Frequently Asked Questions
Everything you need to know about SEO audits, Core Web Vitals, and improving your rankings.
How do I check my website SEO score for free?▾
Enter your URL above. We run a live Google Lighthouse audit and return a comprehensive severity-based report in seconds — no account required.
What is the difference between PageSpeed and Core Web Vitals?▾
PageSpeed is an overall 0–100 performance score. Core Web Vitals (LCP, CLS, FCP, INP) are the specific metrics within that score that Google uses as direct algorithmic ranking factors.
Why does my site rank low with good content?▾
Render-blocking resources, missing canonical tags, or slow server response times prevent Google from crawling and indexing your pages effectively — regardless of content quality or backlinks.
How does AI help with SEO in 2026?▾
AI accelerates content creation, keyword clustering, and internal linking at scale. But it only compounds results on a technically sound foundation — which is exactly what this tool audits.
What is a good PageSpeed score?▾
90–100 is excellent (Grade A). 80–89 is good (Grade B). 60–79 needs improvement (Grade C). Below 60 is poor and directly suppresses rankings.
How often should I run an SEO audit?▾
At least once a month, and immediately after any major code deployment, CMS update, content migration, or after installing new plugins or third-party scripts.
What is LCP and why does it matter?▾
Largest Contentful Paint measures how long it takes for your biggest visible element to load. Google's target is under 2.5 seconds. Slow LCP is one of the most common reasons sites fail Core Web Vitals.
What is INP and is it a ranking factor?▾
Interaction to Next Paint (INP) became an official Core Web Vital in March 2024. It measures how quickly your page responds to every click, tap, and keypress. Google uses it as a direct ranking signal. Target: under 200ms.
Does mobile score affect Google rankings more than desktop?▾
Yes — Google uses mobile-first indexing, meaning it crawls and ranks your site based on the mobile version. Your mobile score directly impacts your search rankings, even for desktop searches.
Can I use these audit results to pitch clients?▾
Yes. Use the 📥 Download PDF Report button to generate a professional 5-page white-label report with full issue breakdown, Core Web Vitals table, and a prioritized action roadmap — ready to share with clients.
