Overstated. This article assumes that: - All online advertising is Google search - That brand search advertising is representative of the entire industry There are plenty of companies making double-digit ROAS (return over ad spend), especially direct response advertisers.

If a company has incrementality tested and is really making double digit ROAS they aren't spending enough haha.

I think your answer is in your comment. Why would the digital marketing guys at Amazon say that their advertising doesn't work and their budget should be cut? They want a bigger budget with more responsibility, not less!

Unlike most companies, Amazon can easily track ad display or click to purchase. While they still can't establish causality (you might have bought it even without the ad), it's still fairly easy for them to calculate if the ads are worth it.

When you have Amazon's scale, you can easily do geo-controlled lift studies like the ones mentioned in the articles to get a pretty good estimate of the incremental ROAS.

The effects may be low but what is the alternative? You suggest there's a digital advertising bubble but to have a bubble with the assumption it will burst, you need to show that advertisers can achieve a better return by doing something else. There's no digital marketing bubble more than there is a traditional advertising bubble. There IS however a conflict of interest in advertising that's caused by the agency whic…

I agree that advertising as a whole might be a bubble. In fact, my next piece is about TV advertising which is arguably worse. See: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3273476 I do think it's more accepted in traditional advertising that we just don't know how well it works. In digital advertising there is a grand illusion of measurement.

Hey Jesse,

I spent 6 years working in ad-tech, and I was researching the incrementality effect of ads, selection bias and stuff like that for last 3 years. I want to let you know that your article is good. Online advertising is not a bubble, but your article perfectly explains why it is much harder than it seems.

Coming from the other end (after someone clicked an ad), I got to say: ads work well. The metric used @work is: cost of sale. The merchant pays for each click on the ad that is redirected to his product page. What seems like a recipe for wasting incredible amounts of money on an army of click bots is working - because the merchant defines a target cost of sale for those clicks, meaning for example he expects a sale w…

But doesn't this ignore the selection effect discussed in the article? IE to use your numbers say you get a $100 sale for every $10 spent on ads. And say your profit margin (outside of ads) on that sale is 20%, so you earn $20-$10 = $10 in profit. However, what if 3/4 of the people who clicked on your ads would have found you anyway, through organic search results or other means? Then that $10 spend only actually gen…

True, you could very well cannibalize your own advertising efforts. I think that may be a problem for brands who already advertise themselves. For example, I agree it makes no sense for Ebay to place an ad for the search term "ebay" if they are already the first search result. If you have a well known brand, you will have a lot of people who will search you out directly. In that case it's a matter of running campaigns and see what sticks - if you spend 10% of your budget on an agency's ad campaign, and very few new customers turn up, you may be wasting money.

But if you have a small to medium online shop, I think it makes sense to have someone run ad campaigns for you on as many domains as possible - and pay only for high quality traffic. If you re-sell shoes from Nike, you will have a very hard time getting a click from someone who would have bought at your shop anyway, because your competitors will pay for Google PLA and other ad campaigns and anyone who is looking for a good offer will run into their ads.

Online ad metrics tell people “what” happened, but people expect it to tell them “why.”

I think the selection effect is much larger for big, well-known companies. Everyone knows eBay, so advertising is obviously going to give decreasing returns.

For smaller, lesser-known companies, I think advertising is much more effective. The chance is much lower that people will know about your product and buy it than if you spent more on advertising.

I find, as a consumer, I disagree with the text only requirement. Videos are certainly off limits as a nuisance. However images convey a lot of information very quickly, and can be visually "skipped" in a way text cannot. When presented an ad for protein powder alongside my workout diets article, I want to see what it looks like. The presentation of the product is an important factor in whether or not I pursue it. It…

And since we re considering new advertising ideas, how the ads are presented matters. We could perhaps be thoughtful about when and how to present ads instead of plastering our sites with more banners than content because that's what adsense says that works. E.g. why are there not ads at the end of the video? Why are there 5 minute ads (seriously?)? Just saying "this worked" is not enough - this might have worked for an ad but destroyed the field for all other ads.

> Beating ad blockers is not hard. Just serve them from the first party domain.

But I've been seeing an increasing amount of talk and effort in the online marketing community about finding ways to bring this first party data into the existing third party data collection machines.

If websites start doing this, all it will do is bring the privacy heat down harder, directly on the publishers themselves. I hope that websites manage to operate without sharing that data with the martech world, but I fear that they won't.

Amazon more or less won didn't it? It doesn't have total domination of ecommerce but frankly it'd run into anti-trust issues if it did. No company is going to do ecommerce bigger than amazon without getting broken up so yeah... amazon.

Moving more and more away from Amazon. If I especially like a product or company, I'll see if it costs about the same to buy direct and do that. I've found that lots of companies actually have better deals on their site or offer a coupon.

Yes.

(1) Yes, I know that Amazon sells some millions or some such different products, but my experience shopping (recently moved and have done a LOT of shopping) is that the company making the product can have a good enough Web site that shows much wider range of products, e.g., for wool blankets many more colors and patterns.

(2) To me the key to Amazon is their quite well done Web site that makes it easy (a) to find products and (b) to get relatively good information about them. But can do well on (a) with just keyword searching at Google, Bing. For (b) can do well at the Web site of company making (importing, whatever) the product.

Then, yes, Amazon also pleases customers with better, faster, cheaper shipping options, their Prime program, good returns policies, relatively close warehouses (Walmart stands to do really well on this as they get their Web site polished), customer reviews of products, Amazon Choice house brand, one account for all the wide Amazon product choices instead of (having to type in banking, shipping details for) accounts at each of a few dozen companies, etc. I have found that if just go shopping at whatever on-line retail sites, can get some bad products, worse than my experience at Amazon; so, Amazon can have some trust from selecting relatively good product. It may be that Amazon can be responsive: The mid-tower case server I built supports error correcting coding (ECC) on both the motherboard and the processor; so I explained to Amazon that for their main memory sticks (DIMMs, duel in-line memory modules) they should offer ECC; they did, and maybe my suggestion helped. Still, IMHO the keys to Amazon have been just (a) and (b).

From the shopping I've done recently, it appears that a lot of retail Web sites just copy a LOT of software architecture and design from the Amazon Web site. So, we can expect that building such a retail Web site is becoming a widely, well understood art and, thus, no longer an advantage for Amazon. Indeed, the company might host their site at Amazon's cloud server farm AWS -- irony here!

Net, it looks to me like the US manufacturers and/or importers can start to do well cutting out the middleman Amazon. Ah, Internet disintermediation!!

Uh, shipping from many local warehouses? When I was at FedEx, and maybe still, shippers could just truck their inventory to Memphis and, thus, get faster, cheaper delivery to their customers -- order in before midnight and delivery before 10 AM the next day, that is, in about 10 hours. Well, FedEx and UPS could still do such -- open a few hundred warehouses, let vendors stock the warehouses with big trucks and deliver to customers with little trucks (bicycles, taxicabs, drones?). Again, a dozing if not sleeping giant here is Walmart.
