Where every click is a journey and every impression counts.
The revenue generated for every dollar spent on advertising, assuming your attribution model isn't complete fiction.
In data retrieval and marketing analytics, the percentage of all relevant content your search or campaign actually captures. High recall means you found everything; low recall means you're basically Googling blindfolded and hoping for the best.
Something that was already made by someone else and is therefore available for immediate use without your input. In fashion, it's the alternative to custom tailoring; in business, it's the escape route from actually thinking about originality.
Revenue generated divided by advertising costs. Every dollar spent on ads should return multiple dollars in revenue, or you're funding other people's businesses.
Automatic auction for ad impressions in milliseconds, where advertisers compete and the highest bidder's ad shows. It's the stock market, but faster and for eyeballs.
Showing ads to people who have already visited your website but didn't convert—digital stalking with a polite veneer and a display network budget.
A Google Ads feature that shows different ads to people based on whether they've visited you before, because once you've been to a party, the host remembers you.
A way to adjust bids for search ads based on whether someone has visited your site before—basically charging different prices based on how interested you think they are.
A marketing phantom—any person, influencer, or demographic segment that mirrors your ideal customer profile so closely that advertisers can target them as a proxy audience for lookalike campaigns, because apparently 'people like your existing customers' needed a fancy noun.
