Google reported a January 2020 core update that started to roll out around 12:00 PM ET on Monday, January 13th.
That rollout was “mostly done” by Thursday morning, on January 16th. We also know that this was a global update, and was not specific to any region, language or category of web sites. It is a classic “broad core update.”
Some industries are reporting this a huge update. “There is massive movement at the top of the SERP for the Health and Finance niches and incredible increases for all niches when looking at the top 10 results overall.”
“It’s another core update where thin content got penalized and where Google put an emphasis in YMYL.” YMYL stands for: Your Money, Your Life. YMYL pages are those that could contain information that has an impact on your money or your life. Google’s Search Quality Guidelines, section 2.3 state: Some types of pages could potentially impact the future happiness, health, or wealth of users.” says Search Engine Land. This could impact Home Health Care.
Google has given advice on what to consider if you are negatively impacted by a core update in the past. There aren’t specific actions to take to recover, and in fact, a negative rankings impact may not signal anything is wrong with your pages. However, Google has offered a list of questions to consider if you’re site is hit by a core update.

The update doesn’t seem to affect as many pages as with the March or September update in 2019. But has similar characteristics.”
