It's not about the quality of the ads, which he argues will get better with more data. It's about intent.
When I search on Google, my natural next action is to click a link. That link can be organic or an ad. If it's an ad Google stands to make money.
When I browse Facebook, my natural next action is not to click a link to an outside service/store. It's to continue to read status updates and browse around. Clicking an outside link is unnatural and unpleasant in this context.
This is the same reason ads on other Google properties such as gmail do so poorly - they may know exactly what you're likely to buy and could therefore present you with the perfect ad, but the activity you're engaged in does not naturally lead to clicking on ads.
From my point of view as an advertiser, how is the CTR even relevant? Why do I care if google has 1% CTR and Facebook has 0,1%? If you assume both has the same cost per click. And I spend $100 on each. I'll still get the exact same amount of people clicking my ads on both.
Why does everyone keep repeating that facebook ads are only for branding, there's no intent, CTR is low? Doesn't the pay per click auction makes all of these irrelevant?
So even if users coming from Facebook are more likely to actually buy something than those coming from Google (which would make Facebook ads more valuable than Google ads, all else equal), the CTR still creates a cap on how much they can earn.
Online advertising is cursed by a near-infinite supply and excellent metrics that immediately connect impressions to actions.
Facebook will know what you want better than Google: they track you across multiple retail sites, see what you are looking at and even get structured data volunteered to them about that stuff.
There are many more adsense ads displayed than adwords - it's google searches vs. most of the rest of the web. Yet it only makes up 1/4 of google's revenue.
Last I checked there was an order of magnitude difference between the value of an adwords vs. adsense ad.
Twitter and Facebook might occasionally be clued in about some of my purchases, but google is in on virtually all of my purchases that are considered while I'm at a computer. They're first past the post and privy to a much higher percentage of what I buy.
My money is on Google.
Facebook still has a lot to prove, but they also have a lot more opportunity to improve.
What's your case for that? They have almost a billion users. How many more are they going to get, and are users outside of the US and Europe (and a few scattered nations) of any value to Facebook at all?
Facebook entering the AdSense market? It won't generate a lot of profit for facebook. The true profit engine for facebook is still the facebook site.
I'm not even mentioning the reach of analytics.
>Do the math on this: instead of growing it organically, we wake up one day and Facebook has taken over Google’s Adsense business. That’s $10B in revenues alone.
I imagine the people best able to predict my next purchase issued my debit card, no?
If you want to start investing based on your beliefs, go ahead. But have a pool of money for that and be ready to lose it.
But for your retirement, diversify.
The guy probably should take some courses on retirement/investment planning.
