What Dr Urls found on 4geeksacademy.com
From the audit of their public home page on 23/10/2026, worst first. Each links to what it means and how it is fixed.
- highCacheable response sets a cookie, so no CDN will cache it
The two headers contradict each other, and the contradiction is silent: the page looks cached, the CDN is configured, and every request still pays full origin latency.
- highMissing landmark elements
WCAG 1.3.1 requires that page structure is programmatically determinable.
- 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.
- mediumEmpty heading tag found
Empty headings waste an opportunity to provide keyword signals and structural context.
- mediumExcessive DOM size
A large DOM tree directly impacts Interaction to Next Paint (INP), a Core Web Vital.
- mediumFont size too small for mobile
Small text forces mobile users to pinch-to-zoom to read content, creating a poor experience.
- mediumForm inputs missing associated labels
Unlabelled form fields are unusable for screen reader users, who represent a significant portion of potential customers.
- mediumForm inputs missing autocomplete attribute
WCAG 1.3.5 requires input purpose to be programmatically determined for inputs collecting user information.
- mediumIcon-only button missing aria-label
Icon-only buttons are extremely common in modern UIs (hamburger menus, close buttons, search icons), but without aria-labels, they are completely opaque to screen reader users.
- mediumImage file too large (>500 KB)
Images typically account for 50-75% of a page's total weight.
- 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.
And 9 more. 8 security findings are not listed on this public page; the site's owner sees them in a full audit after claiming it.
