从1999年到2012年，该期间最长的时期研究了14年的可访问性指标发生变化的证据，该证据是迄今为止研究的最长时期。对WCAG 2.0级A成功标准的自动分析发现，总体上违规的百分比很高。但是，与更多的限制研究不同，这些地点多年来在许多可访问性指标上表现出改进，政府站点的可能性较小，而不是高层人士违反可及性的行为。对成功和失败的原因的检查表明，提高可访问性可能部分是由于网站技术和编码实践的变化，而不是专注于可访问性本身。
Over 100 top-traffic and government websites from the United States and United Kingdom were examined for evidence of changes on accessibility indicators over the 14-year period from 1999 to 2012, the longest period studied to date. Automated analyses of WCAG 2.0 Level A Success Criteria found high percentages of violations overall. Unlike more circumscribed studies, however, these sites exhibited improvements over the years on a number of accessibility indicators, with government sites being less likely than topsites to have accessibility violations. Examination of the causes of success and failure suggests that improving accessibility may be due, in part, to changes in website technologies and coding practices rather than a focus on accessibility per se.
