Largest Contentful Paint is too slow

Your page's main image or headline takes more than 2.5 seconds to show up. Visitors see a blank or half-loaded page, and most will leave before it finishes loading.

First Contentful Paint is slow

Your page takes more than 1.8 seconds before showing any content at all. Visitors stare at a blank screen and may leave before your site even starts to appear.

OG image missing width and height

Twitter/X, LinkedIn, Telegram, and Discord need the image dimensions declared in your HTML to display the preview correctly. Without them, the preview may be skipped entirely or shown at the wrong size — reducing click-through rate when your link is shared.

Open Graph URL missing

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

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.

Primary topic not found in title or H1

Your title tag and H1 are the strongest signals Google uses to understand what your page is about. If your main topic isn't there, you won't rank for it.

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.

Mixed content — HTTP resources on HTTPS page

Your HTTPS page loads some resources (images, scripts, or styles) over insecure HTTP. Browsers block or warn about this, causing parts of your page to break or display incorrectly for visitors.

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.

FAQ section found but no FAQ schema

You have a real FAQ section, but it is not marked up for machines. Adding FAQPage schema increases the chance of reuse in search and AI answers.

No sitemap.xml found

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

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.

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.

Form inputs missing labels

Some form fields have no label. Screen reader users cannot tell what the field is for. Placeholder text is not a substitute — it disappears when you start typing.
