Yes, this is the long-promised post where I share my experience advertising with Amazon and the things I’ve learned — things that could make or break your campaign.

What I’ve Learned Advertising With Amazon

You may remember my past experiences with Amazon Marketing Services (AMS) and the recent plan I’d set for myself. I started promoting in April with 3 kinds of ads:

Ad #1: Sponsored Products, Manual Keywords

This was the bulk of my promos. I chose up to 1,000 keywords for each book and used them to target potential readers.

How does one come up with so many keywords, you ask? Well, there are two easy ways:

The first strategy requires that you find the genres in which your books sells. Amazon does some automatic choosing for you, and you can sometimes see these listed under your book details. If you wish to influence Amazon’s placement of your book, here is a helpful page that details which keywords will place you in which genre, courtesy of Amazon itself.

When you have the category you’re listed under, click on it and you will see what books are doing well that day. My advice would be to choose those with many reviews, as these are more likely to be on the charts for longer. Use both the book’s title and the author name as keywords, and you can easily scoop up a few hundred keywords from this alone.

However, there’s also a better way:

2. Choose Books Also Bought Alongside Yours

Under your title, you will notice the “Also bought” books. Amazon is already linking these to your book, making for a highly targetted group. Just choose the most relevant of these, and you will now have reached almost 1,000 keywords.

Choosing your keywords is probably the hardest party of this kind of ad. However, it can be over in as little as a couple of hours if you do it like I suggested above. After that, all you have to do is come up with a catchy tagline (VERY important!) and set your daily budget and Cost Per Click (CPC) bid.

I chose a daily budget of $5 and an average bid of $.025.

Ad #2: Sponsored Products, Auto Keywords

If you’d rather skip the hard work of coming up with all those keywords, you can trust Amazon to come up with its own keywords. These are automatically selected from your blurb, reviews etc, and aren’t too bad, actually. Set up your budget and CPC bid as above, and you’re set to go in a dozen or so easy clicks.

I did this for some of my ads and got mixed results. For Emotional Beats, auto keyword campaigns outperformed my manual keywords ones. In most other cases, it was the other way around. So, my advice? Try both and see what works for you.

Ad #3: Product Display Upsell

Except for a Sponsored Product campaign, you can also run a Product Display one. The nominal difference is where these appear on the page (see image above), but the real difference lies in targeting: with Sponsored Products, you can target specific keywords, whereas with Product Display you can target specific products.

There are two ways to use this:

1. Target Your Competition

The most obvious way to use a Product Display campaign is by targeting books similar to yours and advertising there. Be sure to only choose books priced lower than yours, as it makes little sense to upsell your product against a (usually more successful) competitor.

2. Protect Your Products

A sneakier way to use Product Display is to protect your own products from your competitors. So, set up one campaign to target your own products and offer either similar products or more expensive ones. To give you an example, I have set up campaigns that promote my series bundles. These ads appear next to each of my individual books. So, if you visit the Pearseus: Rise of the Prince page, you will see that you can either buy this for $2.99 or the entire 5-book bundle for $4.99.

My Results

After the first month of promoting, I realized I was almost $200 in the red. Why? First of all, because I was stupid enough to enter a bid of $35 instead of $0.35 (try to bulk-update these and you’ll see how easy it is to make such a mistake). After a long weekend, this had raised my costs by almost $100.

And second, because I trusted AMS metrics.

Don’t trust the metrics

After two months of promoting, I realize I hate the AMS interface with a passion normally reserved for those who have run over your pet goldfish with their car. You see, unlike Facebook, AMS has no easy way of telling you what you’re spending. The only way you can do this is if you download a spreadsheet with all of your campaigns and using Excel to add the numbers. Not exactly intuitive, right? Even worse, if you want to see how a campaign is performing on a day-to-day basis, well, you can’t. Not even through that spreadsheet. There’s absolutely no time data; just when your campaign started and when it’s scheduled to end.

So, I downloaded a plugin called Machete. This is the only way to know how your campaign has performed through time, plus it gives you an improved interface to see which keywords are under/over performing and allows you to bulk-update them, minimizing the risk of blowing your budget right out of the water. This becomes crucial very fast, as you need to keep an eye on these babies on a daily basis. If you don’t, you can lose your money in no time.

Don’t Trust The Numbers

Which brings me to the main problem with AMS’s metrics: to put it nicely, they’re unreliable. Like, you know that girlfriend you had, the one who stood you up because she forgot she had a hair appointment? The one who was 2 hours late because she had stopped to play with some stray kittens and had lost track of time (true story)?

Well, AMS is even worse than that. They have a metric called ACoS (Advertising Cost of Sales). This is your most crucial piece of information. Basically, this is a percentage telling you whether you’re spending more money than you’re making on an ad. Theoretically, as this percentage approaches 100% you start losing money. When it grows over 100%, you’re spending more money than you’re making and you’re in the red.

So, after downloading the dreaded spreadsheet each day and summing up cost and revenue, I was thrilled to discover I had spent some $500 and made $540. Not bad for my first try, I thought.

And it wouldn’t have been, were it true. Only, it wasn’t. When I added up my actual revenue using KDP/Book Report and CreateSpace, I found out I had only made some $300. After contacting Amazon and asking which estimate was true, I got the following response:

“The estimated total sales in your advertising report will often not match the sales details in your KDP sales report by varying amounts. Your advertising report sales data doesn’t account for declined payments or refunds and may also include sales of associated books, such as if a customer clicks your ad and decides to purchase another book by you or a co-author. Your KDP sales reports show only the final sales numbers and royalties you earned from books published in your KDP account.

The KDP sales reports are exact sales on your book and cannot be under or overstated. The AMS estimated sales is normally overstated as it doesn’t take into account the customer canceling the order (not deciding to make the purchase), Orders declined for payment issues or associated purchases as explained above.”

To me, that’s nuts. How can Amazon not know whether someone proceeded to buy an item or not? Also, how can the AMS estimate be lower than the actual, when it doesn’t even take into account KENP revenue?

Regardless, I have now found out that the actual break-even point as reported by ACoS is closer to 60% instead of 100%. In other words, if a campaign is over 60%, it’s losing money. This is so hugely important that it bears repeating:

If a campaign has an ACoS of over 60%, it’s losing money.

And if you thought this was the last way in which AMS metrics will trip you over, think again: I recently started a Product Display campaign for my Pearseus bundle. AMS reports zero sales, but I actually had 6 sales and some 660 KENP within 2 days of starting that campaign. As I wasn’t advertising it elsewhere at the time, I’m fairly certain these were the result of my AMS campaign.

So, my advice is this: only trust AMS metrics as far as advertising cost is concerned. Don’t hurry to stop a campaign that reports no sales, and don’t trust a campaign that has a low ACoS, unless these agree with your actual sales as reported by KDP/CreateSpace.

The way I’ve stopped losing money (and actually started making a small profit) is to check my billing history every day to see what I spent the previous day. I then compare that to which books I’ve actually sold, and how much I’ve made. Any of these don’t match up, I check the respective campaigns to see what’s going on.

So, in the above example, I know that I have spent $103.13 since May 16th. When I add up my sales from KDP/Book Report and CreateSpace, I find that my revenue is $131,19:

Yes, it looks like a lot of work and requires a calculator. But it actually takes some 15-20′ of my time each morning and it helps me sell books. Which is more than I can say for most other means of promotion.

Scaling Up Is Hard

Another thing I’ve found out the hard way is that scaling up is hard. This is because of a number of factors, such as:

1. Keyword Voodoo

The same keyword that has given you all your sales in one campaign may tank in another. Heck, the same keyword may perform brilliantly on Monday and sink all your profits on Tuesday. I can’t begin to explain this but a sure-fire way to lose a lot of money is to think that by increasing your CPC bid for a high-performing keyword will result in higher sales. My advice? Make all CPC changes incremental, then scale back if you see they backfire.

2. Campaign Voodoo

Like above, only campaign-wide: just because a $5 campaign has a 10% ACoS, don’t think that you can throw another $50 at it and it will generate ten times the sales. Indeed, it may well spring to 1000% within a couple of days. Again, make all budget changes incremental, then scale back if you see they backfire.

3. Be Ruthless

Don’t think that by copying ten times a campaign that gives you $5 a day, you will end up with $50 a day. Most of the copied campaigns will tank. Be ready to pull the plug on them and be ruthless about it. Indeed, be ruthless about any non-performing campaign. Even if it only loses you cents each day, expenses scale up pretty fast. A penny here and a penny there, and you end up spending ten times more than you make.

4. Measure Twice, Cut Once

I know I’m repeating myself, but it’s worth repeating: double-check all of your numbers. Don’t trust any of AMS metrics,except for the billing one: that’s the money Amazon will take from your credit card at the end of the month, so always keep an eye on that. Given the lack of any meaningful time metric, it’s easier to start your campaigns at the first of each month as it’s clearer how many copies you’re selling that month.

If you keep one eye on the billing tab, the other should be on KDP/Book Report and CreateSpace (or whatever you use to sell your print copies). These are the only trustworthy metrics out there.
