>>>that is the FIRST place that any SE or searcher sees.
That's why I don't use it there. I don't want the search engine to see it. A call to action is not relevant to a user query. That is to say, users won't be querying, "batman action figure click here." If the search engine is analyzing the title tag for relevance, then the common assumption is that it's best to keep non-relevant content out of the title tag.
I put the call to action in the meta description, because the SE won't use it for ranking, thus it's a safe place to put it in. Publishing the call to action in the meta description allows you to control the message in the SERPs. Allowing the SE to display a ransom note instead of a Meta Description seems like a wasted opportunity. Why not put a Meta Description in there with a call to action?
I'm not disputing that it won't work, I haven't tried it. But I will give it a shot and see what happens. Regarding not using the meta description though, that seems like a wasted opportunity.
