How to Use Google Analytics Annotations

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.How to use Google Analytics Annotations
