System FAQ

How do I check the SEO of my website for free?

Enter your page URL in the analyzer. The tool fetches your page and audits: title tag, meta description, H1-H6 structure, image alt attributes, and keyword density — all in seconds.

What does a website SEO audit check?

A basic SEO audit checks: title tag (50-60 chars), meta description (150-160 chars), H1 heading presence (exactly one), H2-H6 hierarchy, image alt text, page load signals, canonical tags, and keyword usage.

Why is the H1 tag important for SEO?

The H1 is your page's main heading — Google gives it more weight than other text. Every page should have exactly one H1 that includes your primary keyword. Multiple H1s confuse search engines about your page's topic.

What is a good meta description for SEO?

A good meta description is 150-160 characters, includes your primary keyword naturally, and provides a compelling reason to click. While Google doesn't use it as a direct ranking factor, it affects click-through rates.

How do I fix missing alt text on images?

Add descriptive alt text to every meaningful image on your page. Alt text should describe the image content and include relevant keywords where natural. Decorative images should have empty alt text (alt='').
