Accessibility accuracy improvements
We've launched a wide range of enhancements to our accessibility testing today.
The vast majority of websites shouldn't experience more than a 2% change to their scores, but low quality websites may notice their score go down more.
Mobile support more important
Pages which completely fail to work in mobile, including pages using Flash, are now penalized more heavily. This reflects the increasing importance of mobile to UX, Accessibility and SEO.
New accessibility check for "skip to content"
New accessibility checks for tables
Silktide now checks that data tables include appropriate headers and scope attributes.
Historically the use of tables has been hard to evaluate reliably, as WCAG permits the use of tables for layout which don't have these requirements. However, our data shows that in 2020 the use of tables for layout is almost non-existent, so we have defaulted to assuming most tables are for data.
New accessibility checks for semantic HTML
The absence of basic semantic HTML will now reduce accessibility scores. For example: websites which use large text in place of heading tags.
Placeholder links are now flagged
Under the Content section, we now highlight links which appear to point to nowhere, and which are often left behind by mistake, e.g.
<a href="#">. These links currently have almost no impact on your score.
Using the new checks
These checks will appear automatically the next time you run a report. On average they will impact your score by less than 2%.
