Monitor overall site health
In the new Search Console, you should receive notifications if an important event happens that affects your site. Events include a dramatic change in the number of indexed pages or indexing errors, a manual action or security issue against your site, and other important events.
You can visit your property status page to check for any events. Look for spikes in performance or index coverage, warnings about manual actions or security issues, or other problems.
We recommend that you regularly check the Search Console home page to see if your site is experiencing problems.
