Why another core update so soon? Google said, “We have different systems that are considered core to our ranking process; this month’s core update involves an improvement to a different core system than last month.”

Difference between a ranking update and ranking system? Google said, “Ranking systems are what we use to generate search results. We use multiple ranking systems that do different things. We have a guide to Google search ranking systems that explains some of our more notable ones. Updates are when we make an improvement to a ranking system.”

What do updates do? Google said, “We use automated systems to rank search results, and like anything, these aren’t perfect. We’re always looking at ways to improve these systems to show better results.”

Why do some updates overlap? Google said, “We do try to separate notable updates, so that if they produce changes, site owners can better identify which system is involved. However, given we have so many updates overall, it’s not always possible. In addition, when an update is evaluated and approved because it will make Search better, we don’t want to hold that back.”

Why are some updates during the holiday season? Google said, “We do try to avoid having updates during the late-November to mid-December period when possible. But it’s not always possible. If we have updates that can improve Search, that have been developed over the course of several months, we release them when they’re ready.”

Какая-то different core system... Лажа и словоблудие.

Иными словами, гуглята поняли, что наворотили дел в октябре, и будут теперь одни ошибки покрывать другими, чтобы ОНО как-то работало. Бла-бла ни о чем, но сам факт того, что апдейт выходит сразу за предыдущим, и факт, что гугл не любит обновлений в конце года, говорит о том, что ребятки слегка лоханулись в октябре.

Может, кто-то заметил - GSC выдает неполные данные. Показывает спад по всем параметрам, но в тоже время и страницы остались на своих местах, и другая система статистики этого спада не видит.
