Question 1

What is domain health and why does it matter for SEO?

Accepted Answer

Domain health measures your website's technical SEO foundation - including HTTPS security, mobile-friendliness, proper HTML structure, and discoverability by search engines. A healthy domain (score 85+) ensures Google can crawl, index, and rank your pages effectively. Poor domain health leads to lower rankings, reduced visibility, and lost organic traffic.

Question 2

How often should I check my domain health?

Accepted Answer

Check your domain health monthly as part of routine SEO maintenance, and immediately after any major website changes (migrations, redesigns, CMS updates). Regular monitoring helps catch technical issues before they impact rankings. If you're launching a new site, check it before going live to fix issues proactively.

Question 3

Why is HTTPS/SSL so important for my website?

Accepted Answer

HTTPS is a confirmed Google ranking factor and essential for user trust. Without SSL, browsers display a 'Not Secure' warning that scares visitors away. HTTPS also protects user data (login credentials, payment info) from being intercepted. Modern web standards require HTTPS - it's no longer optional for any serious website.

Question 4

What does 'mobile-first indexing' mean and why do I need a viewport tag?

Accepted Answer

Google now uses the mobile version of your site for indexing and ranking, not the desktop version. The viewport meta tag tells browsers how to scale your site on mobile devices. Without it, your site appears tiny and broken on phones, leading to poor rankings and high bounce rates. It's the #1 technical SEO requirement for mobile-first indexing.

Question 5

How do Core Web Vitals relate to domain health?

Accepted Answer

While this tool checks technical SEO basics, Core Web Vitals measure user experience metrics (loading speed, interactivity, visual stability). Both are essential - domain health ensures search engines can access your site, while Core Web Vitals affect how users experience it. Use Google's PageSpeed Insights tool to check Core Web Vitals separately.

Question 6

I got a low health score - what should I fix first?

Accepted Answer

Fix critical issues first: domain accessibility, HTTPS/SSL certificate, and mobile viewport tag. These have the biggest SEO impact (15 points each). Next, tackle meta descriptions and H1 tags (10 points each). Leave nice-to-have items like favicon and WWW redirects for last. Focus on passing all 'Critical Checks' to reach an A grade.

Question 7

What's the difference between sitemap.xml and robots.txt?

Accepted Answer

Sitemap.xml tells search engines which pages to crawl - it's like a roadmap of your site. Robots.txt tells search engines which pages NOT to crawl (admin panels, private areas). Both are essential for SEO: sitemap ensures important pages get indexed, while robots.txt prevents indexing of sensitive or duplicate content. Every website needs both files in the root directory.
