What Dr Urls found on iodigital.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.
- 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.
- mediumOpen Graph og:image tag missing
Social media posts with images receive significantly more engagement than text-only posts.
- mediumRender-blocking CSS or JavaScript
Render-blocking resources directly impact First Contentful Paint (FCP) and Largest Contentful Paint (LCP), both Core Web Vitals metrics.
- mediumToo many external CSS stylesheets
Multiple CSS files multiply HTTP requests and increase the total blocking time before the page can render.
- mediumURL has excessive query parameters
Excessive query parameters multiply the number of URLs search engines must crawl, wasting crawl budget.
- lowBelow-the-fold images not lazy loaded
Loading all images immediately increases initial page weight and competes with critical resources for bandwidth.
- lowDuplicate heading text on same page
Duplicate headings reduce the uniqueness and semantic clarity of the page structure.
- lowETag header missing on resources
Without ETags, browsers cannot efficiently validate whether cached resources have changed.
- lowImages missing responsive srcset
Without srcset, a 1200px wide image is downloaded on a 375px wide mobile screen, wasting bandwidth and slowing load times.
- lowLink is named for screen readers but has no anchor text
Nothing is broken for users.
And 5 more. 2 security findings are not listed on this public page; the site's owner sees them in a full audit after claiming it.
