How do I use keyword insertion?
To use keyword insertion, you just need to add a snippet of code to your ad text. Then each time your ad shows, Gogole will automatically replace the code with the keyword that triggered the ad.
You can use keyword insertion with any text-based ad, including a standard text ad, an ad with a location extension, or a mobile ad. Keyword insertion works for campaigns that target search only, the Search and Display Networks, or the Display Network only.
