This doesn't in the slightest replace ads though. Before modern internet advertising we had advertising in whatever else had your attention. Ads were meant as we way to simplify and ease distribution.
It's a horrible business in terms of user experience but it's purpose isn't user experience it's meant for businesses to be able to streamline their outreach for much cheaper than the alternatives, imagine cold calls, emails, door knocks, door to door sales has died for this very reason.
I am not trying to explain away the issues and societal problems but they have value of companies otherwise they wouldn't exist. However much people would like to pretend CEOs and founders aren't completely retared.
For initial distribution spikes Ads are the best possible solution, very expensive yes, but if your goal is growth Ads are the most efficient solution since they almost linearly convert spending into visibility in turn producing growth.
Horrible way to do stuff but it's what it is.
Despite lichess being better in every way except marketing, it's still #2.
It's very impressive word of mouth got it to #2, but marketing experts are marketing experts.
It's like why they use sharp points in the hazmat symbol, it just looks bad even if you don't know what it means.
The only companies that have made any real money have had to use Ads from the very start.
You can catch lightining in a bottle but exceptions here prove the rule.
It's absurd to think anyone will care about your product if you don't.
If I make let's say a children's toy, how am I supposed to let people know that this new type of toy even exists? That WHOLE process is advertising, no? Whether I give these toys away for free at a Santa Clause parade, pay department stores to put my toy in prominent shelves, or buy space on Cartoon Network.
How do you get even a single buyer without advertising?
The last thing a marketing company or media provider wants to admit is that any of their services are underperforming, or worse, turning off buyers.
It's true that advertising is a great way to promote a product, but its far from the only way. For many years now I've done what I can to cut all advertising out of my life and yet I still buy lots of things, including things I've never seen a single ad for.
I'm sure it's almost completely subconscious.
The mechanism of how advertising works seems to be not that. I think repeatedly brand exposure does something to the brain and decision making that we don’t fully understand.
Exposure breeds familiarity, which breeds desire, I think.
Even if all you hear is an occasional ad about the company, you might get curious and research them yourself.
That kind of stuff is absolutely worth the cost of ad spend online
But, even if there's a better equilibrium, isn't loading a website crammed with obtrusive ads still a coasean bargain between two parties? Simon P. Anderson and Stephen Coate studied this question in "Market Provision of Broadcasting: A Welfare Analysis" (2005). They identified unpriced externalities like the common-pool attention tragedy, as has been raised in other comments here, and asymmetric information & hold-up, which increase transaction costs.
Divide advertising spend into two components: Informative specs, and persuasive/obtrusive spend. The margial external cost is the sum of profits foregone by rival businesses, and aggregate viewer nuisance. A pigouvian tax with an exemption threshold for factual spreadsheets and apunitive rate on expenditure above that (or visual intrusion metrics) both prices the cognitive nuisance imposed on readers, and collapses the positional arms race between rival firms; transforming the industry from a high-waste prisoner's dilemma to a low-cost, high-information pareto optimum.
Obviously, you still have to watch out for firms goodharting the spreadsheet metric, but that's both a partially solvable problem, and a much better situation than the current nash equilibrium.
They are throwing many different strategies out there through many different avenues and banking one the one that just happens to pull in a new chunk of buyers. It’s like lower-stakes gambling.
