From a marketing pro's perspective you assume that because you have data - reach, impressions, est. click-through rates etc - that you can find a 'quick win' aka get rich rich quick.
So inevitably you try it, then you get some 'tips', then you read a marketing guru's success story, then you start getting ads for ebooks all of which have the best strategy and you really feel that you have no choice but to go for it. It's the FOMO/what if complex magnified by professional requirements to grow at all costs.
From now on I consider online advertising like gambling. You think you can win but the house always win's because you spend more money on A/B testing, copy edits and new keywords all of which create very few leads or deals. You always think you can win too, 8 years later I still go back to online ad's because I feel that there's just that juicy copy, design, content combo round the corner.
