Introduction to Google DFP: Debugging Ad Delivery

Final product image
What You'll Be Creating

This is the fifth tutorial in a series about . DFP is a service that can seem incredibly complicated to the uninitiated—this series aims to simplify it.

In this tutorial,I'm going to review a few examples of the complexity of DFP that you'll likely encounter andteach you how to track down and resolve those problems through use of Google's debug console.

If you're new to this series, please review the earlier episodes before continuing:Introduction to Google DFP Small Business, Beginning Ad Integration With Your Website,Placementsand Placing Orders.

I do try to participate in the discussions below. If you have a question or topic suggestion for a future episode, please post a comment below orcontact me on Twitter @reifman. You can alsoemail medirectly.

DFP: An Acquisition Without UX Improvements

DFP arose from in 2007. It's an amazing service with incredibly powerful features, but it also has a variety of user experience (UX) challenges that can waste our time and confound smart people trying to learn the system.

One fun aspect about this tutorial series is that I'm exploring and expanding my knowledge of DFP as I go. I've used it a bit for years, but I'm revisiting details about it as I try to create a simple explanatory series for everyone—making a complicated UX less intimidating to newbies.If Envato Tuts+ hired someone smarter and more experienced to write this, they might not be tuned into walking you through the difficult aspects.

Personally, I'm surprised Google hasn't done more to address these issues, and that's partly why I highlight them—to encourage them to invest in this area for the rest of us.

If you're less interested in Google's UX missteps and want to jump ahead, skip over this section toDebugging Ad Delivery below.

Reviewing Examplesof DFP UX Complexity

Sign-Up Challenges

In part one, I made a video making fun of how ridiculous signing up for Google DFP can be. The Google folks are brilliant, but sometimes the customer experiences they create are kind of unwieldy, if not downright stupid. There's not much accountability at Google for shipping bad UX. They used to hold "Do no evil" as a value, but perhaps they also chant "Do no DFP UX testing."


It can also be difficult to comprehend DFP's terminology and error messages.

Confusing Terminology and Error Messages

Here's an example of what happened when I thought I'd try to use the Creative Set feature to organize variations of 250 x 250 ads for a client. First,I clickedNew creative set:

Google DFP Bad UX New Creative Set

Then, I tried to add the first of my three images:

Google DFP Bad UX New Creative Set Define the Set

Confusing Error Messages

When I tried to save it, I got a red error message typical of DFP—the message appears at the top of the form, out of context with any specific setting, and without a link to additional information.

Google DFP Bad UX New Creative Set Error

Apparently, Google has aroadblock feature which was now creating a roadblock. How ironic.I had to Google (probably should have used Bing by now) to find out what this meant.

Confusing Help Pages

Then I found a help page calledMaster/companion roadblocks for creative sets:

Google DFP Bad UX New Creative Set Help for Roadblocks

As you start to read it, you realize that their technical writing isn't reviewed for its ease of comprehension. A lot of the help content for DFP is very difficult to comprehend and ambiguous in its use of repetitive, non-descriptive terminology.

Confusing Product Modes

It turned out that I needed to actually turn on the roadblock feature.Eventually, I found theNetwork settings area where I can turn on opt-in Features:

Google DFP Bad UX Enable Features

I still couldn't save my creative set—the same error appeared.

I returned toAdjust Deliverywhere there were new options (subtly appearing but without notice—I had toclick the dropdown to see it), so I choseAlland saved it again:

Google DFP Bad UX Adjust Delivery

It still didn't work. I finally gave up making a creative set.

Let's move on to one of the most confounding aspects of DFP, resolving unexpected problems with ad scheduling and delivery.

Debugging Ad Delivery

If you're ready to learn how to debug your orders and line items, you're in the right place.

Checking Your Order Forecast

When you place your order as we didin the prior episode,Placing Orders, it's helpful to check your forecast to ensure that there's sufficient ad inventory for the line items within your order.

Here's what the final part of the order placement page looked like in our last episode:

Google DFP Place an order targeting

And, when you clickCheck Inventory, you'll see something like this:

Google DFP Check Inventory

Ready Doesn't Mean What You Think It Does

As I mentioned in the prior episode,Placing Orders, once you approve an order, you'll likely see that it'sReady. You might begin refreshing your page to see the ads come up. You might wait a half-hour for Google's DFP latency to expire. And then, you might keep refreshing. Unfortunately,Ready really means that something isn't configured properly.

The status you're aiming for isDelivering. It indicates that your order's ads are now actively appearing in rotation.

There are so many sophisticated, conflicting, multi-level settings in DFP, it can take rocket science to understand why something remains Ready but notDelivering. It's a common confusion in DFP community forum posts.

Fortunately, Google offers a way to debug your orders and sort out what's happening.

Ready But Needs Creatives

Another fun, confusing error you may run into is being told your ad is Ready but Needs Creatives even after you've added a creative—again Google doesn't seem to know that "needs creatives" isn't "ready":

Google DFP Ready Needs Creatives

It turns out that when you selectOne or MoreDisplay Creatives, Google doesn't allow you to use just one creative, only more than one. Again, this is a good example of poor terminology within DFP UX.

By editing the line item toAdjust deliverytoOnly one creative, I was able to fix the line item:

Google DFP Adjust Delivery to Only One Creative

Now, the order reports it'sReady:

Google DFP Line Item Ready

ButReady just means DFP confusion. Here's how to begin to troubleshoot why an order isn'tdelivering.

Google Publisher Console

TheGoogle Publisher Consoleis there to help you review and debug problems with ad delivery. To access the console, load your website with the query parameter ?google_console. For example, visit my example ProTools.io website with this URL:https://protools.io/?google_console.

The page will load normally. Then, you need to activate the console with a keyboard shortcut. PCs useControl-F10. Macsuse Function-Control-F10. At that point, you should see the following:

Google DFP Publisher Console on Open

You can also justappend ?google_force_console or ?googfc to your page's URL: "This causes the console to be automatically displayed when the page is loaded, rather than requiring the keyboard shortcut described." You can see it on my example site.

The console opened to other ad unitswithin my ProTools site, e.g. 468 x 60. Click into the lower panel and scroll down to the ad unit highlighted in yellow, the 250 x 250. Keep in mind, all of this information is publicly accessible. Anyone can see it. It's essentially highlighting ad units in yellow and rewording discoverable JavaScript as a friendly English debug panel:

Google DFP Slide down to our sidebar 250 x 250 ad

There are three links to help you study the issue further. For most, you'll need to log in to DFP to see anything useful.

  1. Open Ad Unit in DFP. This just takes you to the Inventory > Ad Unit within DFP.
  2. Open Creative in New Window. You can refresh this URL and just see what ads come through with the current line items.
  3. Delivery Diagnostics. This is the most helpful one as it shows you which orders' line items compete for the space and what affected the outcome.

Delivery Diagnostics

When you're signed into your Google DFP account and click onDelivery Diagnostics, you'll see a report like this:

Google DFP Delivery Diagnostics

Let's examine some of the key data provided.

AdSense Enabled

If you have AdSense enabled for this ad unit, then the Google network itself may be competing for impressions based on line-item settings. In this case, I'm not keeping AdSense on, so there is no competition.

An upcoming episode of this series will cover how to configure your own paid ads and house ads against the value of AdSense ads.

Targeting Criteria Affecting Competition

Google DFP offers so many ways to target orders' line items to placements and ad units that it's easy to get confused by how ads are appearing or not appearing.

In the example above, it's focusing on my location as the visitorbecause some of the ad units are targeted by country.

Winning Line Item

This section shows which line item won the visit. In this case, neither, but we're not yet sure why.

Rejected Line Items

This section shows which line items were rejected and why. In this case, my line items appeared as "Ahead of schedule." Google states that this indicates:

Delivery for these line items has slowed to ensure that they don't overdeliver.If you want one of these line items to deliver to this ad unit, ensure that its flight dates, quantity goals, and frequency caps are correct.

In other words, they're pacing the appearance of these ad units so that they appear throughout more of the calendar windowfor the line items (the time between the start date and end date). It's essentially spreading the appearance out evenly.

Ready Still Not Delivering

But the console's not clearly explaining why the sample line item for Digital Ocean 250x250 is stuck in Ready and not Delivering like the other line item.

When I refreshed the page, the other line item was delivering and the report was now more confusing:

Google DFP Publisher Console Over Time

It was now reporting that the MWP Test 3 line item was complete and showing 134% progress.

Dear Google DFP UX team, 39 of 1000 goalimpressions is not 134% complete, and a sliver of color on a progress indicator does not indicate 1.34x completion.

Oddly, when I refreshed again, the Digital Ocean ad appeared, but shouldn't have because it was classified asReady. I failed to get a screenshot before I hit refresh again, and then the ad space went blank.

I made some adjustments to the line item to request a higher number of impressions at a higher rate, and changed theDelivery Impressions setting to "Frontloaded" just to see if I could nudge the ad from Ready to Delivering.

It was still failing and it gave me pause.I've written well over one hundred tutorials for Envato Tuts+, but there has been amoment or twoin writing this series where I feel like turning myself into them and saying, "Editorial gods, I'm not the right guy to write this series." And then I see stuff like this—the ad was rejected for "Unknown reason."

Google DFP Failure due to Unknown Reason

Not even Google DFP understands what's happening:

Try running the diagnostic tool again. DFP will take note of what happened so we can investigate.

Frankly, not being a completeexpert at DFP makes it easier for me to document the kinds of things that average Envato Tuts+ readers likely have run into, will run into and will be googling (or binging) for help with.

Google DFP ObtuseLatency for Settings

And then, after a half hour or so, the ad status switched to delivering:

Google DFP Delivering

It also beganappearing in rotation:

Google DFP Ad in Rotation Delivering Successfully

One of the big usability problems in Google DFP is that changes to settings take 30 to 60 minutes to take effect and the system is terrible at sharing the status of your changes with you. It doesn't tell you that changes are pending—you just have to wait, wonder, and try not to tinker with the settings again.

The console is helpful at getting a hint at what's going wrong, but it won't answer everything perfectly. It's a difficult service for Type A people to use without losing their minds.

In Closing

Obviously, the Google Publisher Console is a lifesaver to help you track down problems with the confusing (yet powerful) DFP interface. If something's not working, check your forecast and then debug with the console.

What's Next?

In the next episode, we'll explore placing orders forhouse ads of various kinds.Some house ads are just internal advertisements when you have no other paying advertiser. That's traditionally what the term refers to.They're the last line of response for DFP fill. Other "house ads" youcan configure can earn revenuethrough affiliate relationships—we'll look at ways to do this too.

As the series evolves, I'd love to hear more of your feedback about DFP topics you'd like me to explore.Please feel free to post your questions and comments below.
