Frequently Asked Questions
This focuses specifically on on-page SEO fundamentals (title, meta description, canonical, headings, structured data, image alt coverage); the Performance Health Score instead evaluates loading speed and technical infrastructure factors - both contribute to overall search visibility in different ways.
Missing or poorly-optimized title/meta description tags and images missing alt text are among the most frequently found issues, since they're easy to overlook, especially on pages generated automatically by a CMS template.
No - on-page fundamentals are necessary groundwork, but rankings are also heavily influenced by content quality, backlink profile, and competition for the specific keywords being targeted, none of which this on-page check evaluates.
Prioritizing the highest-impact items first (missing title/meta description, missing H1) generally makes sense, but addressing the full list over time genuinely does compound into a stronger overall on-page foundation.
Re-checking after any significant content update, template change, or CMS migration is good practice, since any of those can inadvertently introduce or remove elements this score depends on.
