The Secrets of Google Ads CTR in 5 Charts

Click-through rate (CTR) is arguably the most important metric in paid search (organic, too, for that matter). It’s a key component in determining Quality Score. It’s indicative of copy that entices prospects to visit your landing pages.

It. Matters.

A lot.

Consumers click on exceptional ads, ads that address their needs or make an emotional appeal, and gloss over bad (or even fine) ones. And while it’s possible that too many clicks can flood your landing pages with un- and under-qualified traffic, if you’re optimizing your landing pages and running remarketing campaigns, the benefits of a high CTR are clear.

Of course, exceptional landing pages and all-encompassing remarketing efforts mean nothing if you aren’t driving a steady flow of traffic to your site, and to do that, you need great ads. What’s the indicator of mind-melting ad copy? CTR.

Given the importance of click-through rate, let’s explore Google Ads (AdWords) CTR (in graphs!).

1. What did CTR look like in 2016?

According to our data, beautiful. Radiant. Dare I say it: unicorn-y.

In 2016, the average SMB account ad CTR across all positions was 3.23%, up from 2.7% just a year earlier. Why the improvement?

According to Larry, the biggest reasons for the increase in CTR are Google’s inherent preference for good ads, an aversion to running “crappy ads (with low CTR and low QS) in the first place,” and the advent of Expanded Text Ads (more on those in a minute). “There’s tremendous leverage in ad text optimization. The top 10% of accounts (the unicorns) are doing more than 3X better than everyone else (the donkeys).”  In other words, a high CTR is a clear indicator of success.

This is especially interesting when you consider that…

2. Many industries have average CTR’s below the 50th percentile

That’s right. According to our industry benchmarks, a CTR of 3.23% would be a welcome sight in the Google Ads UI of almost any advertiser.

Of the 16 verticals included in our research, only one, dating and personals, had an industry-average CTR above the 50th percentile. While this is cause for matchmakers to rejoice, it also means the majority of advertisers aren’t writing the right ads.

How can you ensure your copy’s optimized for above-average CTR’s?

The first step is rather simple…


Shocking, I know.

As we’ve mentioned ad nauseum since mid-2015, Expanded Text Ads are upon us (and they’re awesome).

The format, in which two 30-character headlines are featured prominently atop a larger description line, gives you more room to say something compelling.

As you can see, we recorded some insane increases in CTR across WordStream clients who were early adopters of ETA’s; in some cases, the improvements over standard text ads climbed well over 100%. If that doesn’t convince you to make the jump over to ETA, I don’t know what will!

Just kidding. I’m keenly aware of the hurdle 45% more space in your text ads represents. Boosting CTR’s is great, but, frankly, ETA’s can be a pain in the ass to write.

Case in point: in our own Google Ads account, we actually saw click-through rates dip when we first introduced ETA’s. Why? Simply put, we attempted to mash old (high performing) ads together, creating an account overflowing with “irresistible” Frankenstein copy. (For more examples of what not to do, check out the 7 Deadly Sins of Expanded Text Ads).

Our strategy proved wholly invalid within a week. We reverted back to our top performing standard ads, and the brains behind our in-house PPC efforts rolled up their sleeves and started cranking out brand new copy tailored to the new, expanded format.

Now, we’ve got enough ETA-related resources on our blog to turn you into a PPC copywriting pro. But if you don’t have time to dig in right this second, the next two graphics will show you how simple tactics can lead to massive gains in CTR.

4. Bidding on long tail keywords? Include every syllable in your ad copy

Bidding on long-tail keywords is smart, right? Longer keyword, less competition, more obvious intent.


With standard text ads, it was likely that your long-tail keywords didn’t fit neatly into your copy. They were probably a hair too long to be featured in headlines, and if you managed to work them into a description line they either a) detracted from your ability to include an enticing value proposition/CTA or b) created a painfully awkward line break.

This was a real shame, since long-tail keywords are proven to produce better CTR’s than one-, two-, three-, and four-word keywords, regardless of position.

As you can see in this graph, the more words in the search term, the higher the CTR. And with Expanded Text Ads space is no longer a constraint!

By adding an additional headline, Google has given you the ability to include a long-tail keyword and a call to action within your headline. Realistically, most searchers are going to skim headlines because they’re in bold; many might never see your description line copy. While this is a tidbit disheartening, it provides insight into how one might structure an effective Expanded Text Ad.

That being said, if you’ve got your keywords and a CTA in your headlines, what on Earth should you do with your description line? How do you ensure that your hyper-relevant, long-tail keyword-packed ad copy resonates with your prospects?

5. Fill your copy with powerful emotional triggers

Leveraging the power of human emotion in ads is a tried and true copywriting tactic.

But just how powerful is it?

Emotional ads CTR by ad type

In a word: very.

In a study conducted by one of our PPC Strategists, it was determined that ad copy that combined a promotion with some form of flattery improved CTR by 29%. Only including the promotion or the aspect of flattery alone didn’t move the needle as much as combing the two!

And this study was based on standard text ads: imagine the ways you can weave emotive copy within an Expanded Text Ad! You’ll never have to settle for “Buy now!” again…
