What Dr Urls found on prostarseo.com
From the audit of their public home page on 25/10/2026, worst first. Each links to what it means and how it is fixed.
- 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.
- mediumButton has no accessible text
Buttons without accessible text are announced as just 'button' by screen readers, making them impossible to identify and use for visually impaired users.
- mediumCache-Control header missing
Proper caching prevents browsers from re-downloading unchanged resources, dramatically improving repeat visit performance.
- mediumExcessive DOM size
A large DOM tree directly impacts Interaction to Next Paint (INP), a Core Web Vital.
- mediumForm inputs missing associated labels
Unlabelled form fields are unusable for screen reader users, who represent a significant portion of potential customers.
- 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.
- mediumScripts without async or defer
Synchronous scripts halt HTML parsing while the browser downloads and executes them.
- lowBelow-the-fold images not lazy loaded
Loading all images immediately increases initial page weight and competes with critical resources for bandwidth.
- lowH1 heading is too long
A concise H1 provides a clear, focused signal about the page's primary topic.
- lowImage has empty alt attribute
If a content-relevant image has an empty alt attribute, search engines cannot understand what the image depicts, and it will not appear in image search results.
- lowImages missing responsive srcset
Without srcset, a 1200px wide image is downloaded on a 375px wide mobile screen, wasting bandwidth and slowing load times.
And 5 more. 6 security findings are not listed on this public page; the site's owner sees them in a full audit after claiming it.
