Only July 12, Google announced that its July 2021 core update was “effectively complete.” We saw this core update hit hard on July 2 and July 9 with the entire rollout lasting for 10 days between July 2 and July 12.

This was the second part of a 2-part update that started in June.

For about 6 months leading up to June, there was a ton of buzz about this update. This was one of the very few times in which Google announced a major update ahead of time, calling this the Core Web Vitals update. We’ve been keeping a very close eye on this as your trusted Raleigh SEO company.

Core Web Vitals are the subset of Web Vitals that apply to all web pages, should be measured by all site owners, and will be surfaced across all Google tools. Each of the Core Web Vitals represents a distinct facet of the user experience, is measurable in the field, and reflects the real-world experience of a critical user-centric outcome.

This July update was a bit lesser known, as many thought the update was complete in June. But we’re not surprised to see a round two which is pretty common with major updates. Nobody knows exactly what was in this second round, but it’s certainly something around overall site quality.

While we know that Google updates its algorithm daily with small teaks, we usually see only one or two major updates per year.

This year has been a little different.

  • April 8 – Google Product Reviews Update
  • June 2 – Core Web Vitals Update
  • June 10 – Google Predator update
  • June 15 – Google Page Experience update
  • June 23 – Google Spam Update Part 1
  • June 28 – Google Spam Update Part 2
  • July 2 – Core Update
