3 Free Tools to Help Investigate & Fix PPC Account Performance Changes

My Post (79).pngFiguring out why the performance of a PPC account has changed can be one of the most time-consuming tasks in PPC.

Not only is it a big time drain, but it’s also often associated with a fire drill, done at the urgent request of a boss or client who is demanding answers after something didn’t go as planned.

I’ll cover how a typical investigation is done and share free tools and scripts that can help speed up this process.

Of particular interest is Google’s just-announced ‘Explanations’ feature, which can be a great help when trying to find the culprit when things don’t go as planned.

How to Investigate Account Performance Changes

A typical investigation can consume hours if done manually and usually follows these steps:

  • Finding out you have an issue.
  • Determining if the change was across the whole account or mainly due to a few rogue items like some overly broad keywords.
  • Drilling down deeper into the responsible entities.
  • Collating metrics from various sources to understand if the change was due to a change you made, a change in user behavior, or a change by competitors.
  • Fixing the issue.

Step 1: Know You Have an Issue

We’ve all got a lot on our plates. So, chances are, you aren’t logging into all your accounts every hour.

That’s why it’s so important to have good monitoring in place so that you’ll get an alert if something is going on with an account.

If you don’t have good monitoring, rest assured your client will monitor things for you.

But that comes with a downside: they will yell at you

Also, by that point, things may have gone far off track.

So set up some good alerts and spare yourself that trouble.

You’ll look like the PPC rockstar you are if you squash a problem before it gets out of hand.

Step 2: Find the Best Place to Start the Investigation

Once you know that an investigation is needed, it’s time to find out where to start.

A big change in performance can come from the combination of many small changes or from some isolated bigger changes.

1 + 2 + 1 and 0 + 0 + 4 are both 4

It helps focus your effort when you know where the biggest changes appear to have happened.

Notice I use the word “appear” because it is possible that a campaign with no top-level change actually had lots of positive and negative changes that canceled each other out.

The simplest way to go about this step is to rank campaigns by the biggest net change.

This is simple to do.

Turn on the date range comparison feature in Google Ads. Then filter for only campaigns with a minimum level of data and then sort them from biggest to smallest change.

Step 3: Drill Down Deeper into Impacted Ads Entities

Once you’ve identified the campaigns most responsible for the change, repeat step 2 but now by looking at the ad groups with the biggest change in each affected campaign, one at a time.

Then repeat this again for keywords, queries, ads, etc. After doing this you have a list of individual things that you might be able to fix.

For example, you’ll know which keyword had the biggest drop in conversions and be able to fix its issue.

Or you might find that an affected campaign has no keywords of special note and everything declined equally, indicating that the issue may be due to a campaign-level setting such as a budget change.

As you can see, this recursive step can be time consuming for larger accounts.

Step 4: Drill Down into the Metrics

When you’ve found the entities most responsible for a change, be they campaigns, queries, or something else, it’s time to investigate the underlying cause.

Looking at the numbers will help you hone in on the root cause.

This isn’t easy and requires downloading a lot of data (even data from outside Ads, like Google Trends) and combining it in spreadsheets.

While the Google Ads interface shows metrics in a table, there are relationships that are easier to see in a cause chart, which is illustrated in both the above image from Google and the one below from Optmyzr (my company).

For example, a conversion can only happen if you get a click. And a click can only happen if you get an impression, and an impression can only happen if a user searches for your keyword.

Understanding at which stage of these connected metrics things have unraveled will help pinpoint the likely fix.

An advertiser whose conversions have decreased should look at clicks, impressions, average CPC, impression share, etc. to determine what caused the change.

Once you know the lowest level metric that was impacted, you can correlate that with a likely cause and know if the reason is due to something you changed, something a competitor changed, or a change in user behavior. – Read more
