Usability research and web design from Nielsen Norman Group, Smashing Magazine, A List Apart and Chrome Developers — the craft behind the pages that rank.
Impact is an automatic estimate of how much a story is likely to
affect one website, weighing who published it, whether Google has
confirmed a ranking change, how many outlets ran it, and whether
the wording implies work on your site. It reads headlines, not
your analytics — treat it as triage, not a verdict.
