Add Article/BlogPosting structured data - crucial for AI content understanding

Missing structured data

The page has no Schema.org markup that tells Google exactly what the content is (article, product, company, etc.).

Impact

You're not taking advantage of "rich snippets" - enhanced results with stars, prices, images.

How to fix

Add appropriate Schema.org type (e.g., Article, Product, Organization) in JSON-LD format.

Page needs significant changes to be well-cited by AI systems - start with adding Schema.org and clear content structure

Missing structured data

The page has no Schema.org markup that tells Google exactly what the content is (article, product, company, etc.).

Impact

You're not taking advantage of "rich snippets" - enhanced results with stars, prices, images.

Documentation
7

Add lang attribute (e.g. lang="en") to <html> tag for screen readers

Missing language attribute

The <html> tag doesn't have a lang attribute specifying the page language.

Impact

Screen readers may mispronounce text. This makes it difficult for blind users.

How to fix

Add lang="en" (or appropriate language code) to the <html> tag.

CRITICAL
Content • Accessibility

8

Add labels to all form fields for accessibility

CRITICAL

Add significantly more valuable content - Google prefers long, detailed articles

CRITICAL
Content • Content Quality
10

Enable gzip or brotli compression for HTML, CSS, JS - reduces size by up to 70%

No resource compression

Server does not compress text files (HTML, CSS, JS) before sending.

Impact

Data transfer is 60-80% larger than it could be. Page loads much slower.

How to fix

Enable gzip or brotli compression in server configuration.

CRITICAL
Resources • Page Speed
Documentation
11

Add Strict-Transport-Security header with max-age of at least 31536000 (1 year). This protects users against HTTPS downgrade attacks

Page is not secure (no HTTPS)

Your page doesn't use encrypted HTTPS connection. Browsers show "Not Secure" warning next to the address.

Impact

Google lowers rankings for pages without HTTPS. Users don't trust pages without the "padlock" in the address bar.

How to fix

Install an SSL certificate (many hosts offer free Let's Encrypt) and redirect traffic to https://.

Documentation
12

Add Content-Security-Policy header - the most effective protection against XSS attacks. Start with report-only mode: Content-Security-Policy-Report-Only

Missing security headers

Impact

The page is more vulnerable to XSS, clickjacking, and other attacks.

How to fix
