I analyzed 8 Testlio Portfolio websites and detected 1594 total quality issues. The average quality score is 84.4% (B), with 199.2 issues per site on average.

The biggest issue categories across the category: Other (2587), Content (407), A11y (151). The most recurring specific problems I found: "render-blocking resources delaying initial render" (found on 6 sites); "render-blocking css/js resources delaying initial render" (found on 5 sites); "third-party scripts blocking page load" (found on 5 sites).

Top performers: Netflix, NBA, PayPal (fewest issues). Sites needing the most work: Whatnot, Uber, Amazon (most issues). The gap between best and worst is significant — the cleanest sites have 117 issues while the roughest have 324, suggesting very different levels of QA investment.
