Most Google AdWords advertisers are aware of dynamic keyword insertion (also, good info here), which is a way to dynamically insert the searcher's keyword phrase in your ad copy. But there are other insertion tags available to advertisers, outside of the keyword tag.

Each is fairly self-explanatory for any of you who are at the level of using them. I just thought I would create a page that lists all the currently available insertion tags that can be used in Google AdWords.
