It's probably easiest to explain by a ficticious example.
I have a Paris Travel Guide Website.
I have 3 keywords in one ad group.
- Paris Restaurants
- Paris Bars
- Paris Guide
These are all active.
When I go to google search and type in the last term with a random
keyword added eg Paris Guide Shoes or Paris Guide Cabbage my website appears in the sponsored links. Normally the only one to do so.
I don't see this happen in any of my other campaigns or ad groups. On the whole it's probably positive and results in targetted traffic but I'm curious to know why it's happening.
