// how it works

What the check looks at

Speed & quality
Performance, accessibility, best practices and SEO scores on a simulated phone, real-visitor speed where there is enough traffic, plus server response time, HTTP version and compression.
Search & AI visibility
Title, description, headings, canonical, sitemap and structured data, and whether robots.txt blocks AI crawlers like GPTBot, ClaudeBot and PerplexityBot.
Accessibility
Accessibility score, images without descriptions, form fields without labels, missing page language and contrast problems.
Security basics
HTTPS and redirects, certificate expiry, security headers, and server software versions that should not be public.
Email deliverability
SPF, DKIM and DMARC records for your domain: the setup that decides whether your emails reach the inbox or land in spam.
Tracking & platform
Which analytics, ad pixels and consent banner are installed, and what the site is built on.
Share previews
How a link to your site looks on social media and in chat apps, and which preview tags are missing.

Core Web Vitals: what counts as good?

Google's thresholds, judged on the 75th percentile of real visits.

Metric	Good	Needs improvement	Poor
Largest Contentful Paint (LCP)	≤ 2.5 s	2.5 to 4 s	> 4 s
Interaction to Next Paint (INP)	≤ 200 ms	200 to 500 ms	> 500 ms
Cumulative Layout Shift (CLS)	≤ 0.1	0.1 to 0.25	> 0.25

LCP is loading speed, INP is how quickly the page reacts to taps and clicks, CLS is how much the layout jumps while loading.

Common questions

Is the site check free?

Yes. No sign-up and no email needed. The latest results for each address are kept for 30 days so shared links keep working, then deleted. We don't see who ran a check unless you send us the results.

How are the speed scores measured?

We load the page on a simulated mid-range phone over a throttled mobile connection and score it from 0 to 100 with the industry-standard method. For sites with enough traffic we also show how fast the page was for real visitors over the last 28 days. Lab scores move a few points between runs, so look at the pattern rather than a single number.

Why check whether AI crawlers are blocked?

Assistants like ChatGPT, Claude and Perplexity read the web through crawlers such as GPTBot, ClaudeBot and PerplexityBot. If robots.txt blocks them, your site is less likely to show up in AI answers. Blocking can be a deliberate choice; the check makes it visible.

What is a good PageSpeed score?

90 to 100 is good, 50 to 89 needs improvement and below 50 is poor. The score comes from a lab test on a simulated phone, so treat it as a guide. For search, how fast the page is for real visitors (Core Web Vitals) matters more.

How do I check SPF, DKIM and DMARC?

Enter your domain above and open the Email tab. The check looks up your SPF and DMARC records and the most common DKIM selectors, and says which are missing or too weak to protect your domain.

Can I check a competitor's website?

Yes. Add a competitor address next to yours and the results show side by side, sorted by what matters for your own site.

Is this a full audit?

No. It is an outside view of what can be tested automatically from one page. A proper review covers the whole site, analytics, content and code. If the results raise questions, send them over and we will take a closer look.
