Google Analytics annotations are an easy way to keep notes on changes that affect your website’s traffic and sales goals. Annotations can be made private or visible to all users – allowing everyone who works on an account to see when a promotion went live, an Adwords campaign was paused, an affiliate campaign was launched, when the last web design change happened, and more. These annotations are viewable as notes directly on the Google Analytics graph and can save hours of work trying to figure out where and why there were changes in website traffic and sales.
Create an Annotation in Google Analytics
To create an annotation in Universal or Classic Analytics, sign into your Google Analytics account and click on the reporting tab at the top. Directly under the graph that appears on your default view, click the gray arrow and then select + Create new annotation. You will be able to type your note, pick the date you would like to apply it to, and whether you want your annotation to be shared or private. Google Analytics annotations will appear on all graphs and can be deleted or edited at any time.
