On June 3rd, 2019, Google started rolling out a broad update to the ranking algorithm, named the June Broad Core Update. They announced this over the weekend, and on June 2nd, there were outages of Google services (Gmail, YouTube, Google, Google Cloud) across the world near certain data centers. (Guess they needed to reboot the servers to integrate these changes).
My prediction is that many SEO “talking heads” will pontificate on this update, and start selling E-A-T audits and June Update recovery packages. I also predict that this is simply a fine-tuning of their ranking algorithm. There was a similar update in March, which Google also announced, the March Broad Core Update, which seemed to target general quality, and not anything specific like older updates did (Panda, Penguin, Hummingbird, etc).
Remember that Google makes several adjustments to the ranking algorithm on a daily basis, and many SEO’s believe they do split testing, or A/B testing with certain rankings. This update is probably more of the same, a dialing-in on quality signals, and not aimed at any specific spam signals.
Time will tell. If you continue to match keywords to search intent, create good content, let customers complete the tasks they are trying to achieve, have a well-designed website, build links, and proactively build your brand, you should be in good shape, and this is nothing to worry about.
