What Dr Urls found on webtech.fr

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.

• high
  Time to First Byte (TTFB) is slow

  TTFB directly impacts all subsequent loading metrics.

• medium
  Form inputs missing associated labels

  Unlabelled form fields are unusable for screen reader users, who represent a significant portion of potential customers.

• medium
  Form inputs missing autocomplete attribute

  WCAG 1.3.5 requires input purpose to be programmatically determined for inputs collecting user information.

• 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.

• low
  Below-the-fold images not lazy loaded

  Loading all images immediately increases initial page weight and competes with critical resources for bandwidth.

• low
  Data table missing caption

  Table captions help all users (including screen reader users) understand the purpose and context of the table before navigating its contents.

• low
  Excessive inline CSS

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

• low
  Excessive inline JavaScript

  Inline JavaScript cannot be cached by the browser and must be parsed and executed every time the page loads.

• low
  Key resources not preloaded

  Without preloading, the browser discovers critical resources late in the parsing process, delaying their download.

• low
  Missing preconnect hints for critical origins

  Each new origin connection requires DNS resolution, TCP handshake, and TLS negotiation, adding 100-300ms of latency.

• low
  WebSite schema markup missing

  Google reads WebSite structured data on the home page when choosing the site name it shows above your results.

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