Meta description length is not optimal

Your meta description is either too short (under 100 chars) or too long (over 165 chars). Google typically shows 100–165 characters. Too short leaves value on the table; too long gets cut off with "…".

H1 heading is missing or duplicated

Every page should have exactly one main heading (H1) that tells Google what the page is about. Missing or multiple H1s confuse search engines and lower your rankings.

Canonical URL is missing

Without a canonical tag, Google might index multiple versions of your page (with/without www, with/without trailing slash) and split your SEO value between them.

Open Graph title missing

When someone shares your link on social media or messaging apps, no title appears — just a blank card or raw URL. This drastically reduces engagement with shared links.

Open Graph description missing

When someone shares your link, no description shows under the title. Social media cards look incomplete and get fewer clicks than ones with clear descriptions.

Open Graph image missing

When someone shares your link on Twitter or Telegram, no image appears. This cuts click-through rates by up to 3×.

Open Graph URL missing

Social platforms and crawlers have no explicit canonical sharing URL for this page. This can weaken preview consistency across channels.

Images are missing dimensions

Images without dimensions can cause layout shifts while the page loads. That hurts Core Web Vitals and makes the page feel unstable.

No structured data (JSON-LD) found

No Schema.org JSON-LD blocks were found on this page. Structured data helps Google understand your content and display rich results. It also improves AI search visibility.

No analytics tracking detected

You can't improve what you don't measure. Without analytics you have no visibility into traffic, user behavior, or conversion goals.

X-Frame-Options header missing

Your site can be embedded in an invisible iframe on another website. Attackers use this technique (called "clickjacking") to trick your users into clicking things without realising it.

X-Content-Type-Options header missing

Browsers can "sniff" your files and treat them as a different file type than intended. This can allow attackers to upload files that get executed as scripts. This header prevents that.

Referrer-Policy header missing

When visitors click a link to leave your site, their browser sends your full URL (including any private query parameters) to the destination site. A referrer policy controls what gets shared.

Content Security Policy missing

There's no policy controlling what scripts and resources your page can load. Without this, an attacker who injects any code into your page can do anything — steal cookies, redirect users, exfiltrate data.

Missing Permissions-Policy header

Without a Permissions-Policy header, any script on your page can access the camera, microphone, geolocation, and other sensitive browser features. This is a defence-in-depth security header that limits exposure if you get XSS.

No DMARC record found

DMARC tells email providers what to do when someone forges your domain in emails. Without it, phishing attacks using your domain name are trivially easy.

No CAA DNS record

Without a CAA record, any certificate authority in the world can issue an SSL certificate for your domain. A CAA record restricts which CAs are allowed.

No privacy policy link found

A privacy policy link is legally required in most jurisdictions if you collect any user data. It also builds trust with visitors who want to understand how their data is handled.

No structured data (Schema.org)

AI assistants and search engines use structured data to understand what your product is. Without it, they have less reliable context.

Not enough readable text content

This page has only about 196 readable words after ignoring scripts and styles. That may be too little context for AI systems and search engines.

llms.txt references broken links

Your llms.txt lists pages that don't load. AI systems following these links will hit dead ends.

No sitemap.xml found

A sitemap helps crawlers discover the pages you want cited and indexed.

Weak brand or author entity signals

The site does not expose many signals that identify the people or organization behind it.

No content date signal found

Perplexity and Google AI Overview weight fresh content significantly higher. Without a date signal, your page may be treated as potentially outdated — reducing how often AI systems cite it in answers.

No question-format headings found

ChatGPT, Claude, and Perplexity extract headings as Q&A pairs and include them in answers with a link to your page. Pages with question-format headings are cited more often in AI responses.

First paragraph too short for AI citation

AI systems like ChatGPT, Claude, and Perplexity extract the beginning of your page as citation passages. A short or absent opening paragraph means they have little useful content to cite, reducing how often your page appears in AI answers.
