For this week’s The Optimizer’s Guide series I’ve invited an expert in paid search, Ryan Jenkins, to talk about a display URL strategy he shared with me recently (after posting a comment on my post How SEM Works). I hope you find it as useful as I have. – @JRachwalski

When in the course of running SEM ads, it becomes necessary to write effective display URLs. “Wait a second, did he just say, ‘write effective display URLs?’” I did indeed.
I know what you’re thinking. You’re wondering what it means to ‘write effective display URLs’. They’re just URLs right? Well, yes and no. I’ll explain, but first some vocabulary.
What is a Display URL?
The display URL is the green Internet address that appears in the last line of your text-ad. It serves two purposes: (1) to quickly show the person searching who the ad is for, and (2) to give them an idea of where they’ll be taken if they click on the ad. The display URL is limited to 35 characters so keep it simple.

How is that different from the Destination URL?
The destination URL is the actual link that the searcher will be taken to. It is usually a longer (up to 1024 characters), more complicated looking URL such as this one:
http://www.amazon.com/Mountain-Three-Short-Sleeve-Medium/dp/B000NZW3J8/ref=sr_1_2/175-6251903-2449637?ie=UTF8&s=apparel&qid=1281735683&sr=8-2.
Pretty ugly isn’t it? To a normal Internet-using person that link doesn’t make a lot of sense. That’s why it’s so important to have a friendly-looking URL in the display URL!
Optimizing the Display URL
Let’s say you own a car dealership called “Bennett Car Sales” and you sell Toyotas. And let’s assume your website is BennettCarSales.com and you want your ad to appear every time someone searches for “affordable Corolla.” You have a couple of options when it comes to writing your display URL. Let’s start with the comprehensive display URL option.

While the URL depicted (in green) is a technically accurate representation of what site the visitor will land on, it’s difficult to read and doesn’t really add much value to the ad beyond validating that they will indeed be going to the Bennett Car Sales website. So, let’s see if we can clean it up a bit by getting rid of the http://.

Better, but it still takes a split-second of mental energy to interpret the display URL so let’s go a step further.

Ahh, much better. The capitalized letters make it much easier to read what the display URL is supposed to say. Can we go any further?

Ooh, that’s even clearer. Just as the https:// wasn’t really necessary, the www. is also a bit distracting. Most people know by now that a string of text followed by .com is an Internet address.
While any of the ads above would be technically acceptable, they’re still missing a key opportunity. Try this on for size:

Notice how I’ve gotten the keyword “Corolla” in there one more time. Having that there will do two things: first, it will tell Google that your ad is especially relevant for searches that include the word “corolla”; second, placing the word “corolla” in your display URL gives Google one more opportunity to bold it when the word is included in a search query (which can draw a tiny bit more attention to your ad).
Another option might be to put the keyword in a subdomain, like so:

Summary of options for writing Display URLs
So you basically have the following options:
Do Display URLs really matter?
At this point, you may be wondering “Is it really worth putting so much thought into such an uninteresting part of the ad?” to which I say, “It’s absolutely worth it.” Since your CTR plays such an important role in determining both your Quality Score and your actual CPC, then you’ll want to ensure that you put some serious thought into how you write your display URLs.
So which ad should you use? That depends. What are your goals? How do you measure success? Are you looking for as many visitors as possible? Do you need each visitor to be worth X dollars in profit?
Your business is different than other businesses. Your website is different than other websites. And your visitors are different than other sites’ visitors. That means that the right answer for your site might not be the right answer for someone else’s site. Maybe you need high-profit visitors and you’ve found that your campaigns are most profitable when you use the entire long URL in your display URL. So be it.
In the end, it all comes down to testing each option yourself using your own goals. One ad might have a great Click Through Rate (CTR) but a low Conversion Rate. Another ad might convert really well, but it hardly gets clicked on. Test each ad against your own goals and determine which best meets your particular needs.
A note regarding Google’s policies
While Google provides plenty of options when it comes to how you structure your display URLs, there are some important limitations to keep in mind.
- The display URL and Destination URL must match each other. Unless you’re temporarily sending visitors to a tracking link (e.g. http://bit.ly/d8QM8j) that immediately redirects them back to the displayed domain, Google will reject your ad.
- The display URL must match the domain of the landing page. You can’t send visitors to the destination URL but then immediately redirect them to a different website. This is considered to be shady and your ad will be rejected. Your Display URL must match the domain of the page that the visitor permanently ends up on.
- All display URLs must match within the same ad group. All text-ads in an ad group must send visitors to the same Destination URL. So while you can have “BennettCarSales.com” and “BennettCarSales.com/Corollas” in the same ad group, you cannot have “BennettCarSales.com” and “BennettCorollaSales.com” in the same ad group.
If you want more information about Google’s policies, check out their AdWords Help center.
In summary
In the end, you have many options when it comes to display URL. What’s right for you comes down to:
- Define your goals
- Test… test… test
- Test some more
