Thomson Financial believes Google will generate an astonishing $21.31 billion in mobile advertising revenues in 2009. I don’t. Moreover, I think Google is going to have a hard time migrating Adwords to mobile.

But $21 billion? Next year? Surely there is No Chance of that happening. I’ll be amazed if Google can generate a tenth of that from mobile, in 2009.

With numbers like that being thrown around it isn't too surprising to see that Google CEO Eric Schmidt has turned into the company’s chief mobile cheerleader, although maybe the analysts Thomson polled should be headhunted for that task.

Here’s what Schmidt said about the mobile internet at the Davos conference, a few weeks ago:

“It is the recreation of the Internet, it’s the recreation of the PC story and it is before us — and it is very likely it will happen in the next year.”

Maybe so. But there are some big differences with mobile. I've been wondering whether Google, which is investing big into its Android mobile OS and Gphone projects, is going to be able to pull off the same trick twice. That is, to migrate Adwords onto mobile and generate billions in revenue every quarter, as it currently does via the internet.

Why won’t Adwords work so well on mobile?

Let’s just take a moment to think about why Adwords works so well online. It is largely because these ads are shown in a demand-driven environment, linked as they are to specific search queries.

These queries are identified by the advertisers, who write specific ads and specific landing pages to encourage relevant response and high conversion rates. Context and targeting: two cornerstones of advertising.

Why else does Adwords work so well? Well, it works because people are in ‘search mode’. They click results specifically aimed at their wants and needs. As such, Adwords works a treat. Note that Adsense works less well, mainly because people are not in ‘search mode’ when browsing news stories on publisher websites.

Adwords also works because it proves to advertisers that it works, making it far easier for them to spend ever-larger sums with Google. Before the internet, measuring the effectiveness of ads was very flaky / costly / time-consuming.

With Adwords, you can track a search query through an ad to a sale, and measure the ROI on that search term very accurately, in near-as-dammit real time. That’s why, in a nut, it took off.

It’s the same on mobile, right?

Wrong. The ad targeting will be there, and the measurement will be there, and there might be a bunch of other cool stuff thrown in (eg the location-based stuff – the so-called holy grail of mobile advertising). But what won’t be there is the consumer’s intent to buy, there and then, via the mobile internet. A little bit of consumer desire perhaps, but not intent. And anybody who thinks otherwise is a nut. It will undoubtedly change, but not overnight.

With mobile, the response metrics could look extremely screwy when compared with Adwords proper, assuming people don’t start to ignore the complexities of shopping via a handset. The clicks might be there, but the conversion rates should look a lot different.

Of course Google could try to join this up and make it very easy for people to buy via Google Checkout, which has a unified log-in system, but gaining that level of penetration among advertisers is a big ask. And I still come back to the killer question: why would you buy something via mobile? Why not wait until you’re in front of your laptop, or in a store, where it is much easier?

The key takeaway here is that Google Adwords keyword pricing should be vastly different (ie, much lower) on mobile. Advertisers love Adwords online because they can track click to sale. But location-based services such as ‘nearest Italian restaurant’ are not necessarily going to be measured in this manner, unless we get into m-vouchers, mobile bar codes, or somehow matching up the mobile number to the restaurant bill.

I’ll leave any thoughts on ‘m-currency’ and ‘mobile wallets’ to one side for now, although the theory is there (so is the bureaucracy).

Exception to the rule #1: RETENTION!

Despite all this mithering I do actually think that shopping via mobile handsets is a firm reality, even though it doesn’t seem to be happening yet on any kind of scale. It is a consumer / mobile user trend that has yet to take off. The thing is, shopping via mobile doesn’t need to be so reliant on paid search, as it is today on the internet. It's a marketer mindset thing.

See, shopping has nothing much to do with mobile ‘advertising’, or at least it shouldn’t, if retail companies do the right thing by their customers.

That’s right:, I said ‘customers’. Consumers and customers are two very different beasts, and should be treated differently. Consumers are merely ‘prospective customers’. You advertise to consumers, whereas you market to your customers. And mobile might make it easier for them to become ‘repeat customers’, if you do the right things.

Think about it. Amazon wins so much repeat business from me because I can buy a product using the one-click checkout process. If Google focuses on the roll-out of Checkout and achieves some kind of critical mass among Adwords advertisers, then perhaps a one-click purchase process will be possible via mobile phones. Or maybe you'll need Checkout to be able to buy Adwords in the first place. But from what I’ve heard, Google Checkout isn’t terribly popular, and is certainly struggling for traction here in the UK.

Unless it’s easy to buy – in other words, no dastardly seven-page form-filling process to be negotiated via that tiny keyboard on your handset – then I see no reason why you wouldn’t wait before placing your order. Who needs anything that badly?

With existing customers, mobile can become a really powerful tool in generating additional business. If I were working at a large retail, finance or travel company I would focus on building widgets and mobile experiences that allow customers to use their handsets for browsing, saving, comparing and buying. This would make mobile an extension of the online channel. And it should be very easy, and not built on keyword costs or banner ad clicks, or whatever.

The upshot here is that mobile, for all of the hype, could become a very useful in driving up customer retention rates. The internet has always been seen as a platform for customer acquisition, which has led to a lot of lazy thinking among marketers. Isn’t it a bit silly to keep throwing money at paid search to re-acquire customers that you should already have relationships with? I think it’s madness, personally.

Exception to the rule #2: TELEPHONE ORDERS!

The second exception to the rule is that mobile phones are, rather obviously, telephones. In some sectors 99% of sales occur via the telephone, leaving a paltry 1% for online and mail order. Maybe Madwords will introduce click-to-call functionality? Now that would work, and it would work very well for some businesses. 

There is of course an obvious issue here. It tends to be the older person who prefers to order via telephone, whereas mobile internet usage is a young person's game (like it or not). So unless the oldies suddenly start buying internet-enabled handsets in their millions - and subsequently surf the mobile web with intent to buy - then this click-to-call model wouldn't generate the kind of numbers the analysts are forecasting.

Overall, I think Google might be in for a shock if it plans on making tens of billions a year from Madwords. I’m pretty sure the plan is far grander than that, and, in terms of its mobile advertising business, it probably covers display ads, video ads, maps-based listings, and so on.

But as far as Google Adwords is concerned, the transition to mobile should be far more of a challenge than Thomson Financial is predicting. We’ll soon find out.

What do you think? Have you ever bought something via your mobile phone? Do you imagine that you will anytime soon? Why don’t you do this?

Isn't Adwords just another way to say keywords, logos, or trademarks.

If so, and I were Google, I would be building the GPhone around the Neoreader.

If Google incorporated the application on their mobile device consumers and web users could click on physical world objects such as logos, trademarks, keywords, RFID, 1D, and 2D codes to get information one click and/or purchase them and not have to worry about licensing another companies technology.

Why limit the imagination? Build around it.

What if Apple owned it for the iPhone?

I agree that Google would be facing challenges in the Mobile Ad business. Adwords on the mobile will not work as it is on the net, because mobile internet experience is not going to be solely browser driven. If Mobile LBS takes off as hyped (which i guess it will) then the mobile LBS applications will be of a different breed. They would not be the typical web driven applications running on web browser as we currently experience. Most of them would be native mobile applications running in their target mobile o/s and Google need to be thinking about a innovative strategy on how effectively to integrate madwords with these 3rd party mobile applications.

Chris, you make some good observations and I agree that many companies, including Google, will find many challenges as they move further into the mobile web. Bango has been a leader in the mobile web since 1999 which means we have encountered and solved many of the issues Google and others will currently be seeing.

Let's start with what Bango is most famous for - our mobile payment platform. You mention about the difficulties surrounding how to pay for stuff on the mobile phone and touch on a couple of key points. Firstly paying with your mobile phone should be much more convenient than via a PC - it's always with you and it's more personal. However, many companies try to do web-style payments on the phone - so entering personal details, card numbers, PayPal or Google Checkout account numbers and so on. Entering any details on a mobile phone is a pain, small screens and small keyboards, and directly results in a noticable drop in transaction success (conversion).

The reality is that to make a mobile payment none of that information is really needed. There are ways to automatically identify individual consumers through the relationship with their network operators and indeed customers can pay for stuff via their phone bill. Bango has been able to reduce the payment experience down to clicking on a "buy" button and confirming the payment - no login, no distraction. With these simple steps we get much higher conversion rates than seen on traditional PC web sites. This is a key element to the success of payment on mobile yet it's the main part missing from all the other payment providers. You can read more at

The second item to mention alongside adwords and any other search or advertising systme is analytics - without good data you cannot accurately promote your site, content or brand. The problem is that solutions like Google Analytics and other traditional web tools do not work on mobile. They give no data or false results. This is because javascript, cookies and other techniques do not work on mobile handsets. Again it's back to the user identification. Precise tracking on mobile can only be achieved reliably through link-based tracking. This is one of the techniques we use in Bango Analytics (

As you point out, the internet on mobile is a huge growth opportunity for us all, including Google and friends. But if not done right we run the risk of dissapointment or missing opportunities by only delivering the PC web on mobile rather than welcoming all the added benefits the devices and usage models bring.
