By default, Adthena loads on the Trends Report section automatically once you login and it shows you Share of Clicks. In the graph you will be able to see your top competitors included.
Sometimes, you will not see your brand included in the graph and you may wonder why? If you're not running any paid search advertising on Google at the moment, Adthena will not include you in the Reports automatically as it does not consider you a paid competitor.
If you still wish to see your brand in the graph, you can add yourself in the Named Competitors Group.
