Telling- Agencia de Publicidad y Branding en Barcelona

What Dr Urls found on agenciatelling.es

From the audit of their public home page on 21/10/2026, worst first. Each links to what it means and how it is fixed.

• high
  Slow server response time (TTFB > 3s)

  Page speed is a confirmed Google ranking factor, and TTFB is the foundational component.

• high
  Time to First Byte (TTFB) is slow

  TTFB directly impacts all subsequent loading metrics.

• medium
  Above-fold images not prioritized

  The Largest Contentful Paint (LCP) element is often a hero image.

• medium
  Images missing width and height attributes

  Missing image dimensions are the leading cause of Cumulative Layout Shift (CLS), a Core Web Vital and ranking factor.

• medium
  Missing meta description

  While meta descriptions are not a direct ranking factor, they significantly influence click-through rates.

• medium
  Open Graph og:image tag missing

  Social media posts with images receive significantly more engagement than text-only posts.

• medium
  Stylesheets loaded in body

  Stylesheets in the body block rendering of subsequent content and can cause visible layout shifts as styles are applied incrementally.

• low
  ETag header missing on resources

  Without ETags, browsers cannot efficiently validate whether cached resources have changed.

• low
  Excessive inline CSS

  Inline CSS cannot be cached separately by the browser, so it is re-downloaded with every page load.

• low
  H1 heading is too short

  Very short H1s like 'Home' or 'Blog' do not give search engines meaningful topical signals.

• low
  Images missing responsive srcset

  Without srcset, a 1200px wide image is downloaded on a 375px wide mobile screen, wasting bandwidth and slowing load times.

• low
  Images not using modern format

  WebP images are 25-35% smaller than equivalent JPEG images, and AVIF offers even greater savings.

And 7 more. 7 security findings are not listed on this public page; the site's owner sees them in a full audit after claiming it.
