To gain a better understanding of viewer interaction with display URLs, User Centric, Inc. conducted an eye tracking study measuring the length of time users spend looking at display URLs on Google search engine results pages. Thirty individuals participated in the research, each performing twelve searches using Google.com.
The results of the eye tracking study confirmed that the display URL is an important component of a PPC ad. The display URL captured a significant portion of the time people spent looking at each PPC ad, as shown in the tables and heat map below. For PPC ads served above the organic listings on the left side of search engine results pages, the display URL garnered over three times more gaze time (0.53 seconds) than the text description (0.15 s). Further, the display URL in PPC ads in the top position on the page above the organic results received the same amount of gaze time as the headline, 0.65 s.
Average gaze time (in seconds) per visit to a Google search results page:
The general location of a PPC ad on the page had a significant impact on the gaze activity the URL received. Not surprisingly, the display URLs of the top three ads on the left attracted more attention than the URLs of the top three ads on the right. Display URLs presented on the left received almost three times as much attention (0.53 s per URL) as URLs on the right side of the page (0.19 s per URL).
The length of time spent looking at a URL also varied by the specific position of the ad. The URL located within the first ad was looked at the longest while the URL within the third ad was looked at the shortest. This was true for ads on both the left and right sides of the page.
Within ads on the left, display URLs received, in general, more attention (0.53 s) than the ad text descriptions (0.15 s) but less than the ad headlines (0.70 s). This is not surprising because in those PPC ads, the display URL is located to the left of the text, directly below the headline, which makes it more prominent than the description text but less prominent than the headline.
On the other hand, URLs within ads on the right received less attention (0.19 sec) than both the headlines (0.27 s) and ad text descriptions (0.30 s). The display URLs for ads on the right are the least salient ad elements, as they are presented at the bottom of the PPC ad, below the text description.

Adding Descriptive Keywords to Display URLs May Reduce Click-Thru’s
Understanding that display URLs receive a significant amount of gaze time is not simply a branding issue. The display URL can be altered in attempts to improve results. The most common manner in which this is done is by adding descriptive keywords to the end of the domain name. A Google employee in account management actually encouraged us to test this tactic.
In our experience, adding keywords in front of the domain name fails in the majority of cases, particularly for domains that have significant name recognition and brand equity. However, adding keywords at the end of the domain name increases click-thru rates often enough that it is worthwhile to test.
Shown below is an example from a test of display URLs. The three ads are identical except for the display URL. The goal of the test was to determine if adding “eye tracking” to the display URL would increase the click-thru rate of a PPC ad promoting User Centric’s eye tracking service. The first ad simply features the domain name as the display URL, the second ad includes the keyword term added to the end of the domain name, and the third ad includes the keyword in front of the domain name.

In the test of the above PPC ads, the version featuring only the domain name produced the best results. Adding the keyword “eye tracking” at the end of the domain name in the second ad resulted in about a 5% decrease in click-thru rate, which was not surprising. The most dramatic result of this test was that adding keywords in front of the domain name decreased clicks by over 25%! Not to mention that our ISP charged a fee for an extra top level domain name.
Another drawback of adding descriptive keywords to a display URL is that this form of “keyword stuffing” may reduce the branding value of a PPC ad by cluttering up the display of the domain name.
Domain Name in Display URL Has a Major Impact on Click-Thru Rate
The value of an identifiable domain name in a display URL was highlighted by a test conducted for iNest Realty. Their parent company, RealEstate.com, is a much more recognizable domain name. The test was conducted to determine the impact of using the stronger brand name in the display URL of PPC ads. The test ads are shown below. The only difference between the two PPC ads is the display URL.

New Homes & Home Builders

www.RealEstate.com
Utilizing RealEstate.com in the display URL resulted in a 20% greater click-thru rate for the bottom PPC ad. Based solely on that information, it might appear that the bottom ad was the winner. However, the ad’s conversion rate was abysmal. In order to comply with Google guidelines on display URLs, a landing page had to be created for this ad on the Real Estate.com server. The page was co-branded for both iNest and RealEstate.com. Visitors did not like the experience of clicking on an ad with one display URL and then seeing information about a different brand. Thus, iNest was paying for a 20% increase in clicks, while generating fewer conversions. If the test had not been ended quickly, it would have been an expensive lesson on the importance of providing users with a good experience. However, the test provided a good demonstration of the positive impact a recognizable domain name in the display URL can have upon click-thru rates.
Conclusion
The results of our eye tracking study and the other two tests show that display URLs are an important component of PPC ads. Modifying display URLs as a test poses a danger of reducing the branding value of a PPC ad by cluttering up the display of the domain name. However, the potential long-term benefit of acting upon a successful test can easily outweigh the short-term cost of a failed one. Thus, for many PPC advertisers, a closely monitored display URL test is likely a worthwhile effort.

Here's something else to watch out for when using custom display URLs in your ads: make sure you redirect these to the right landing pages if the displayed subdirectories don't already exist on your site. It's definitely the exception, but apparently there are some people who copy the display URL (example.com/keyword) rather than clicking the big ol' linked and tagged headline in the ad. I've repeatedly seen a small fraction of type-in traffic coming directly to URLs that appeared only in PPC display URLs and nowhere else. If someone types out your fake, keyword-rich URL from the bottom of your ad, don't lead them to a missing page.
Ah, that's a very good point! I've seen it happen to one of our clients just last week.
I was thinking of asking about redirects for this reason before I got to your response. Thanks for the tip.
My team had wondered about this and had been talking to our development team about creating some system to automatically create redirects from our display URLs - the sheer quantity of ads we have meant doing this manually was never going to be an option. I then had the opportunity to do a bit of research into how many people actually do copy and paste display URLs that don't actually exist. Over a five-month period the number of instances of this amounted to 0.01% of the actual clicks we got. To get the point, I think this is really good advice and should definitely be followed if it's easy to do so, but if it's going to require an investment, the case for it might not really be there.
I do the copy paste behaviour sometimes - when I'm trying to save the company some money. If I've aleady clicked on the ad once, and I need to find the page again, then I prefer not to click.
Great tip! I never even thought of that!
hey, Randy, nice post on a useful topic.
I would love to see a couple of extra bits of info added:
Without those it's difficult to judge the conclusions.
Personally I've had a lot of success adding terms to the end of display URLs. I usually favour /Key-Words or /KeyWords (ie hyphen or no-gap rather than underscore).
Presuming you're targeting the exact match term "Eye Tracking", I'd encourage you to give an ad like this a go & see whether you reach the same conclusion:
Hope that's useful!

Love the eyetracking research.
It would have been interesting to test the effect of a www.realestate.com/inest display URL - you get the brand awareness of realestate.com but also the consideration of the iNest brand.
The iNest case study does emphasize the importance of working closely with the consumer marketing team - any increase in brand awareness potentially lowers CPC/CPA for the search marketing team. In fact, we've even had some success in asking consumer marketing to shorten a product's (new) slogan so that it can fit into our Google PPC ads!
Something to remember when you consider the brevity required in Google and places like Twitter and Facebook...
Hi Rand, nice post, i recently did some analysis of brand Vs. generic domain name on a medium sized PPC campaign and it came back with a clear result that generic domains specific to that keyword industry massively out performed the branded version of the domain...this is my findings https://www.leewoodman.co.uk/blog/25022009/346697/citys-info-on-generic-domains/
The adverts were run simultaneously over a 3 week campaign and the results were vastly different, the two domains Swansea.info and netCardiff.co.uk were run with the same advert creative and a maximum cost per click of £0.10. netcardiff.co.uk received a CTR rate of around 13% where as Swansea.info was consistently receiving a CTR of 56% which is an almost unheard of figure in any main stream PPC campaign. The domains are specifically targetted at the tourism sector/city information and Swansea.info in my opinion hits the nail on the head for what users are looking for and according to the results above the users agree.
Over and out
Wooder, I´m glad to confirm with in depth studies what we thought, we did it with cctlds, such as cityname.com.mx, for instance, against brand.com , and by far, city names were winners !
Actually, an SEOmoz reader named Randy wrote this post, not Rand. Pay attention to blog authors--Rand's not the only one who writes on our blog. :)
Hey Randy! sorry about that! Good post!
Hello Wooder,
Thanks for sharing that. Those are amazing results. Your test will get the .info domainers too excited but is certainly worth testing on our campaigns.
This is an excellent article. I've been thinking a lot about display URLs (and actual URLs) lately and have even swapped/mirrored sites for PPC campaign purposes, just to buy and use a better URL. If possible, a generic, descriptive URL can be a killer in PPC, it can contain your keywords which get automatically bolded, and really drive home the point. The display URL is just another headline and in my opinion it may be MORE important than the headline!!!!
What a great post, nice aggregation of interesting information. Thanks für sharing this!
Nice research Randy. lot of small things which you come to know after testing.
Great post Randy, you should also test capitalized words Vs non capitalized words in display URL.
Randy, Nice post, we have done some pretty basic tests about Display urls using Generic or descriptive domain names against brands with the same ad, same bid, etc , particulary in the travel industry and CTR´s on the ad using the generic domains ( city names) were , sometimes, 10 times higher than the branded ones !, You bet is something pretty powerfull to take advantage of...,
thank you for sharing your thoughts!,
Mariano.
This eye tracking stuff fascinates me. And it's another point in favour of generic domain names (there are so many valid reasons for choosing one over a coined domain).
I recently published the results of a study I did testing the effect of using a generic domain name that's an exact match to the niche covered by the Adwords campaign vs a non-specific, "coined" domain name.
For the purposes of the study, all other factors (ad headline, body copy, bids, landing page etc.) were kept constant - the only factor that was varied was the domain name.
My tests showed that an on-topic domain (ElectricBicycles.co.uk - the chosen niche was electric bicycles) outperformed a semi-generic domain (YourBikes.co.uk) and a coined non-generic (InAHurry.co.uk) by generating up to twice as much traffic as the alternatives. This came from a combination of higher CTR and more impressions (Google rewarded the generic even though the campaign was set to serve ads more evenly)
I've written up the study in detail, including statistics for each ad variant, performance charts, a look at click distribution vs ad position and some analysis and conclusions.
I think that capitalizing the first letters of the URL is a really good way of increasing CTR, but i have noticed that Google doesn't allow such action anymore I have tried several times, It will show capitalized on your account but it's actually not on the search engine results ...
Correct me if I'm wrong
Great post, you provide a lot of helpful information regarding PPC advertising. Pay Per Click advertising is essential to any website that is trying to build up your traffic flow and increase profits. If your are interested in further knowledge of PPC advertising then you should check out <a href="https://www.dalaigroup.com/ppc-pay-per-click.html">DalaiGroup</a>
So, what you're saying is that if I put a link, like https://www.sequim-real-estate-blog.com in the actual post, it's going to get more attention than if I href it, like <a href="https://www.sequim-real-estate-blog.com">real estate</a> in the content?
I've long appreciated the value of testing variations to the display url in AdWords ads. In most cases it does work very well.
Your article is an excellent explanation of why it can be so successful. I'm definatley going to book mark this one.
Readers maybe interested in this article that shows three different ways of using the display url in their ads.
https://www.adwords-adviser.co.uk/3-tips-to-make-the-most-of-your-adwords-display-url
Definately helpful information, suprising at first that it gets so much visibility but when you come to think about how people actually read the web and skim the top, bullet points, and then look at the bottom it actually makes sense.
Thanks for the information, its very interesting. Do you have any figures for the change in conversion rates for ads with an extra subdomain or trailing directory ?
I wonder if the extra keywords are acting as a filter, and preventing people clicking on "www.randomdomain.com/Widgets" if they aren't interested in widgets. If so, then you'd see the CTR drop, but the number of conversions might not.
This could give you the opposite effect to your iNest vs. RealEstate example - you get the same sales, but at a lower cost.
Alun.
But is it worth creating more redirects? I try to avoid creating redirects, if possible. My URLs are too long to fit in a ggle ad. So would you recommend creating them anyway, redirects that is? Is the value that significant?
Wow that's a great post - definitely one for the main blog isn't it?
What I found the most interesting is that the description matters least in the ads above the organic results ...
Great post Randy, always love to see these eye tracking studies and your write up is very good, almost like reading a lab report!
The one thing I would like to see added is some information about the participants, their regular search usage levels, search skills etc. Just helps to get a better idea of the generalisations that can be assumed from the results.
Keep up the good work!
Cheers,
Andrew
I concur, I think it would be great to know more about the participants. Perhaps it would be good to also provide them with a related questionnaire?
Good to see you're using a statistically significant sample size.
All good chaps!
I have played around with both variations in the past, sometimes it works, sometimes it doesn't!
Normally the domain names I have been advertising are not big brands, so I focus my branding element mainly when a customer lands on the site, and try to get as high a percentage as possible click through from the advert.
Cheers
Thanks Randy, Daniel, and Mark. You have all given me something to think about.
I am working on a new client campaign now, and I think I will do an extra version of each ad with the keyword in the display URL. I have tried the keyword in the URL but not the same ad in each version. What I did not think about doing and should have, was redirect the URL properly. I do use custom 404's but that is not the same as re-directing to the right URL.
For the test, User Centric had the participants input terms that we had preselected into the Google search text box. "Credit scores" is an example of one of the terms that was tested.
Thanks for the text ad suggestion. I'll give it a whirl.
Great post, Randy. Thanks for the confirmation that Display URLs are as important as they are.
It would be interesting to know if subdomain or subdirectory URLs had an even longer look rate than "clean" URLs.
Sorry to say, we did not test "keyword stuffing" of display URLs during the eye tracking study, so no data is available. The learning that display URLs garner as much gaze activity as they do was a mildly surprising result discovered during a review of the results of the study.
Two things that I noticed that confuse me a bit.
First of all, why would you have to pay a fee to your ISP for an extra top level domain on the third (EyeTracking.UserCentric.com) ad? The display URL doesn't have to be valid, as long as you own the TLD. In other words, EyeTracking.UserCentric.com does not have to exist, therefore you wouldn't have to pay for it. And why would you have to pay for a subdomain anyway?
Second, Its hardly a fair test if you're changing the ad text. Ads 1 and 2 have the same, where 3 has an entirely different one, with a significantly altered message.
I have to say, I've had a ton of success adding the main keyword as a subdomain for the display URL. Especially for eCommerce stores, as in Ice-Skates.MikesSports.com. Of course, a recognized and trusted domain should probably get their name right out in front, as in SportsAuthority.com.
In regard to purchasing an extra top level domain name, please see Mark Alves comment above. BTW -- the cost was so minimal as to be barely worthy of consideration.
In regard to the test ppc ads, mulitple text and headlines were tested with the display URLs. In User Centric's experience, the tests of putting the keyword in front of the our domain name failed in each case. However, as you indicate, the results may be quite different for an e-commerce site.
I'd be interested in the methodology. When you sit the subjects down for the eyetracking test what are they told to do? Also what's their past internet experience?
I think I tend to skip over the ads but will look at a URL if the title looks interesting - is there some problem in the method in that the subjects know they're supposed to be checking something about search quality and so will perhaps dwell on URLs in case they're missing something (because they want to appear knowledgeable?)?
I'd have thought spammy URLs might get a longer look as you're trying to work out if you trust the site based on the URL and there are more compnenet to look at and assess.
Lastly, on a different point, couldn't you have sniffed the request URL to know whether to serve the iNest or RealEstate content? (even if they're on the same page you could do a page scroll with javascript, eg https://demos.flesler.com/jquery/scrollTo/ ).
In regard to the display URL test conducted by iNest, we considered it important not to harm our parent company's brand. Thus, if a viewer clicked on a Real Estate.com display URL, it seemed important to take them to a RealEstate.com co-branded page. We delivered visitors to a co-branded landing page that was created for the test . However, the co-branded page added an extra click to the experience, and diluted the branding of both websites. Not only did visitors not click over to the iNest server, very few of them continued onto additional pages on the RealEstate.com server. Determining how to provide a good user experience while delivering visitors to a different website than they are expecting is a challenge that we were unable to overcome.
I am also curious about what the subjects were told as the heat map seemed unnaturally skewed towards PPC ads. Where they told to look at PPC ads or the search results in general?
There is also the relationship between the keyword searched and displayed in the URL i.e. if bold or not. Bolded will attract the eye.
Also not particularly clear on whether the ads that caught the lingering eyes of the subjects got the clicks in the real world....
I guess Google already knew about this, or they wouldn't have changed their policy regarding the displayed URL last year !
;-)
great stuff !! really impressing and accurate.
thanks for sharing
This is fantastic! I'm right in the middle of refining a PPC campaign now and I was wrestling with the Display URL's. Thank you! I will test on.
I'm getting about a 2% CTR on search and about 1% on content. Does anyone have metrics for this? Without knowing conversion yet, is there a standard against which I can measure my CTR success/failure?
These kinds of posts should be promoted to the main blog, imo.
Great info. Thank u!
