What Dr Urls found on sequello.com
From the audit of their public home page on 27/10/2026, worst first. Each links to what it means and how it is fixed.
- highContent wider than viewport on mobile
Horizontal scrolling on mobile is one of the most common mobile usability failures flagged by Google's Mobile-Friendly Test and Google Search Console.
- highSlow server response time (TTFB > 3s)
Page speed is a confirmed Google ranking factor, and TTFB is the foundational component.
- highTime to First Byte (TTFB) is slow
TTFB directly impacts all subsequent loading metrics.
- mediumExcessive DOM size
A large DOM tree directly impacts Interaction to Next Paint (INP), a Core Web Vital.
- mediumImages missing width and height attributes
Missing image dimensions are the leading cause of Cumulative Layout Shift (CLS), a Core Web Vital and ranking factor.
- mediumLink has empty anchor text
Anchor text is one of the strongest signals search engines use to understand the content of the linked page.
- mediumOpen Graph og:image tag missing
Social media posts with images receive significantly more engagement than text-only posts.
- mediumPage size exceeds 3 MB
Page weight directly affects load time, which impacts Core Web Vitals (particularly Largest Contentful Paint), user engagement, and bounce rates.
- mediumScripts without async or defer
Synchronous scripts halt HTML parsing while the browser downloads and executes them.
- mediumStylesheets loaded in body
Stylesheets in the body block rendering of subsequent content and can cause visible layout shifts as styles are applied incrementally.
- lowBelow-the-fold images not lazy loaded
Loading all images immediately increases initial page weight and competes with critical resources for bandwidth.
- lowBroken heading hierarchy
Heading hierarchy provides a semantic outline of the page content.
