Silktide Index
The Silktide Index ranks thousands of websites by how accessible they are, so organisations can see how they compare with others in their sector. We test every website in the Index every month with the same automated testing that Silktide customers use, against 2.2, and publish the results as a new edition of the Index.
From the November 2026 edition, the Index shows two accessibility scores side by side, V4 and V5, and covers more than accessibility: it now also shows how brands appear in AI answers, and how people use the web. If your score changed between the October and November editions, start with What changed in the November 2026 Index.
