Web Design vs. Analytics: 7 Little Web Design Decisions That Cause Big Analytics Problems

Andy Crestodina

Every web design is a combination of hundreds of little decisions.

Web designers make recommendations and judgment calls, thinking about the client, their visitors and a dozen other things. These decisions affect search rankings, load time, conversion rates and yes, Analytics.

  • Are goals and conversions easy to track?
  • Is content performance easy to measure?
  • Does the site make it easy to see what visitors want?

Here is a checklist of ways in which web design decisions can help or hurt your Analytics. If you keep these in mind during your project, setting up Analytics (and measuring the results of the new site) will be a whole lot easier.

1. Blog in a directory vs. blog on a subdomain

Where does the blog live? Is it in a directory or on a subdomain? 

Analytics impact: Tracking content performance

The location of the blog content can make tracking easy and automatic …or require you to do some fancy Analytics work. Here is a comparison:

Option 1: Blog in a directory (www.company.com/blog)

Want to see the performance of your blog posts? Just go to Behavior > Site Content > All Pages report and type blog into the filter box. Voilà! There they are.

This isn’t just for the blog. Anytime you want to track content of a similar type (products, jobs, recipes, etc.) it’s nice to have it in a directory.

Option 2: Blog on a subdomain (blog.company.com)

These make it easy to use a third-party tool. Want to host your blog on Hubspot? Build a content hub at Uberflip? No problem. They host, no hassle. Just put it on a subdomain and link to it from your main navigation.

But what does this look like in Analytics? Not great. You can set up a separate view for your blog, and track those visitors, but you still have a big problem tracking people as they move between the blog and the main site.

When a visitor clicks to go to your blog, it looks like they left. A visitor who starts on the blog and then goes to your site looks like two visitors. And if they hit the back button they are recorded as three separate visits!

problem with subdomains

Traffic is over-reported and success and failure look the same. That’s bad.

The fix: Set up a filter for tracking subdomain traffic

You can create a new view and set up a filter so that all traffic on your domain (traffic to every subdomain) are recorded within that view. It’s a bit complicated, so here’s a video with the step-by-step process.

Warning! Never set up your blog on a separate domain, such as www.companyblog.com or company.blogspot.com. This makes tracking in one Analytics view impossible, and it’s also a huge problem for your search rankings because it dilutes your Domain Authority.

2. Thank you pages vs. Thank you messages

What happens after someone fills out a form? How does the website say thank you? 

Analytics impact: Goal tracking

Some websites don’t have thank you pages. Instead, they show a little thank you messages on the same page. This makes tracking tough.

By default, Analytics only tracks pageviews, recording when visitors go from page to page. So the easiest type of goal to set up is a “destination goal” which records when a visitor reaches a certain page. To set up these goals, you simply tell Analytics the destination, the thank you page.

The thank you page is also a great opportunity to welcome your new lead. Give them more content, set expectations, say hello. This is your first interaction with your new prospect. Make it a good one!

You can also offer them another conversion. This website has an offer to subscribe to our newsletter on the thank you page after the contact form. Each year, hundreds of people subscribe to our newsletter from that thank you page.


The fix: Event tracking

If your website has thank you messages, you’ll need to set up “event tracking.” This is a way to track non-pageview interactions, such as button clicks that don’t take the visitor anywhere. It requires more fancy Analytics setup, usually through Google Tag Manager. Not necessary or recommended.

3. Contact page form vs. Email addresses

Does your contact page have a contact form? Or does it have email links?

Analytics impact: Goal tracking

Some web designers skip the contact form completely. They just add an email link and call it a day. You’ll find email addresses all over websites, in footers, in headers and on team pages. But they punch a hole in your conversion data.


email-links vs contact-form

This is why email links made it to our list of 15 things to remove from your site immediately.

The fix: More event tracking

But why? Let’s just use contact forms.

4. Pages with URLs vs. popups, tabs, expandable content areas

Does your site have a page for everything? Or do some interactions just show more on the same URL?

Analytics impact: Content performance tracking

Here again, those non-pageview interactions are trouble. Every click by every visitor is a choice, usually to see more information. But you can’t easily see that they made that choice if it doesn’t bring them to a new page.

Here’s an example of two “pages.” The visitor is on a recruiting site browsing jobs. They decide they’d like to learn more about a certain job so they click. They now see more information, but the URL never changed …because the information is in a popup window.

In Analytics, it will look like this URL has some very long visits and a very high exit rate. When in fact, the visitor may be browsing dozens of jobs. Wouldn’t it be nice to know which jobs are getting the most views?

There are a surprising number of non-pageview interactions that aren’t tracked by default. Here’s a list of 16 blind spots in Analytics.


Every time a designer builds these into a site, they create a tiny gap in Analytics. Usually, it’s no big deal. Sometimes, it’s a disaster.

The fix: Site structure

Even though you could fix the Analytics issue with tons of event tracking, it won’t solve the other issues. No URL means no search rankings, no easy sharing and more friction for visitors who use the back button.

5. The multi-topic page vs. A page for each topic

When to use long pages? Is there a page for each topic? Each service?

Analytics impact: Content performance tracking

Beyond popups and tabs, some websites make Analytics difficult because they aren’t organized. They combine everything on one page. The same problem is caused by a different mistake. This time it’s about content, not usability.

Some web designers will put many topics on one page, without making a page for each separate topic. It’s a content strategy mistake that causes big Analytics issues.

It’s also a disaster for SEO. Why? Google doesn’t rank websites. It ranks web pages. If you hope to rank for something, you need a page on that topic. No page, no rank.

Kelsey Jones, Founder, Six Stories
“If your page is covering different topics that require different sections or headers, put them on different pages. Let’s say you’re a pet boarding and grooming facility. You could separate out your pages three different ways: 
  • 1 boarding page, covering dogs AND cats, then the same for grooming
  • 2 separate pages for dogs and cats, covering the services available for both
  • 4 separate pages for each service and pet

Think about what is most useful to your customer. Would pet owners want dog grooming information when they are a cat owner? Probably not. So in this case, separating by type of pet is the best way to go.”

This is common (and destructive) on services pages, but happens everywhere. Ever seen a team page that lists everybody? With no bio page for each team member? That’s a missed opportunity to rank for each person’s name, and to measure the traffic to each person’s bio.

The fix: Separate the content

If it’s a topic, service, product, location or person, it gets a page. Separate the content and give every entity its own URL.

6. Integrated email sign up forms vs. capturing addresses on-site

What happens when a visitor subscribes to the newsletter? Do they stay on the site? Or do they land on a page on a different domain?

Analytics impact: Goal tracking

Here’s another web design decision that affects conversion tracking. Connecting your signup form to your email service provider can save you time. Every new subscriber goes right into your list. But it can cause problems.

First, you can’t use a destination goal. The visitor left the site, so there isn’t a goal URL. Tracking the conversion requires events. If the thank you is on another domain, Analytics thinks they left, so it looks like a failure, not a success.

This decision also goes beyond Analytics, into messaging and marketing.

You don’t have control of the thank you pages on your email service providers website. And that thank you page is an opportunity to offer more and get more in return. But if you send them away, all bets are off.

Ask a few questions before deciding if and how to integrate.

  • How much control do you want over your visitors’ experience and your Analytics?
  • How often do you send email? How much work would it take to import that list of subscribers into your email system before sending each email?

The fix: Don’t send subscribers away

Either send the signups into your email provider through backend integration or just collect the address on your website, in your own database, then move them manually before sending a newsletter.

It takes a few minutes to export/import, but you’ll give your subscribers a better experience and you’ll get more accurate tracking in Analytics.

7. Site search with query parameters vs. path-based URLs

Does the site have a search bar? How is it built? What appears in URL on the search results page?

Analytics impact: Tracking of search terms

When your visitor types something into your site’s search box, they land on a search results page. If the phrase they searched for is in the address bar with an equal sign and a parameter in front of it, you’ll have easy access to a very valuable report in Analytics.


The Site Search > Search Terms Report shows every phrase that visitors entered into your search box. Search tools for visitors are listening tools for marketers. It’s a gold mine for website planners. With a few simple settings, it turns into The Report of Broken Dreams. So useful.

And it’s easy to set up if the address bar shows the phrase. It takes just a few clicks. You can find the instructions here.

The fix: Set up a filter to pull the query from your page path

If your web developers built things differently, if the search term isn’t in the address bar, you’ll need to set up an advanced filter to pull the query from the “page path.” Not fun.

Can’t web designers and Analytics get along?

Analytics is hard enough. Let’s not make it harder than it has to be. Work with designers and developers who understand how Analytics and websites can play nicely together.

  • This is definitely informative! It is interesting to see how page views can be skewed so easily. At some point I am looking to buy an internet business, so this helpful on what to watch out for when buying a business from a seller because they could have their site setup completely wrong.



  • Great article Andy (as always).
    No doubt without analytics it’s hard to improve.

    My question is how do you see the balance between design / UX and their impact on conversion optimization vs. ease of measure?

    For example – sometime having a pop up that opens when clicking a contact us button may convert better than opening a contact us page.

  • Andy, this was a great article…very practical and helpful! Thanks!

  • Great post.

    For #3, you can track clicks to email (or to call) as Google Analytics events using the Google Tag Manager Click URL trigger contains “mailto:” (or “tel:”).

  • For marketing reasons, I understand and agree with your advice to use contact forms vs. email addresses. But as a user/customer, I hate contact forms. Too many times, my queries have gone into a black hole never to be answered. Whenever I see a contact form, I go back onto the site and try hard to find a direct email address. I think it’s harder for someone to ignore a direct email. So I advise clients that if they can’t commit to answering all contact form queries within 24 hours, they probably don’t want a contact form. They’re only frustrating potential customers.

    • Thanks for the input, Jane. Have we talked about this before? I have a few friends/marketers who feel strongly that websites should have email links. I understand. I also feel responsible to warn clients who do this that they’re conversion rates will be underreporting results. It’s an Analytics gap.

      It’s one of the million tradeoffs in digital marketing! Do what’s best for your visitors, but do it with eyes wide open about the broader impacts. 🙂

  • Great post (as usual) Andy! I’ll add one more to the list. I imagine you could come up with a better name for it, but I’ll call it “Discernable url structure vs ambiguous”. You start to touch on it in the blog discussion, but it can go way beyond that for many sites. But to carry your example forward, I see some sites which, while they don’t use a blog. subdomain, they also don’t use a /blog/ folder in their url either. So there’s no way to look at ONLY the blog pages when reviewing their analytics.

    But as I say, it can go much further. For an ecommerce site, I usually like to look at just the Product Detail pages, or just the Category pages. But I very often come across clients who have url structures which don’t tell you what kind of page it is. So instead of a product detail page like abc.com/prods/this-really-cool-product, the url will just be abc.com/this-really-cool-product. In that second url, with no other information, we can’t filter it out in Analytics to know to group it with other product detail pages. It has the same url structure as a catgory page, a regular landing page, etc. Even if they just do something like includ the SKU in the url or something to make it something you can set a filter on, it can be a big help in improving your site (the purpose of analytics!).

    I have a client who is a Media site, a magazine, and one of the things they offer is a few different Directories of service provider on their site–a directory of Summer Camps, a directory of local doctors, etc. These directories include paid listings, so it is a revenue source for them. But they recently redesigned their website and now the urls of all the directory listings are the same. Instead of abc.com/camps/provider1 and abc.com/doctors/provider2, the urls are now abc.com/directory/provider1 & abc.com/directory/provider2. See the difference? We used to be able to look at the performance of all the Camp listings very easily, but now there’s no way to discern that. It can really hinder the ability to isolate underperforming sections of a site and focus on improving them.

    URL structure is such an important consideration in planning out a website. Obviously it can have significant SEO implications. But it also affects how well you can analyze the site performance. Put thought into it before developing the website!

    • Great point, Tom. I’ve seen this before …and we’ve done this before. True confession: we built a site with a huge recipe section, but recipes aren’t in a directory. They were all at the root. Harder to measure.

      We fixed it somehow but I can’t remember how. It might have involved a custom dimension or content group. In any case, it definitely required some programming. I think they added something to that template to inject a bit of tracking into GA.

      Possible to fix, but unnecessary. Careful planning of URL structures is part of web development. Minimize redirects, preserve authority, make analysis easier, improve search friendliness, eliminate need for canonicalization, etc.

      It’s amazing how many details there are in this business!

  • Andy, great intro article – curious as to how you think this applies to mobile responsive design. What are the one or two design challenges that you see which may cause Analytics issues there?

    • Hey there, Elijah!

      Mobile responsiveness actually makes Analytics better. Back in the day, mobile sites were at separate URLs, which was horrible for GA. Responsive design brings everything together.

      AMP on the other hand can cause issues. It means there may be two URLs for a given page. This is one of the reasons I have mixed feelings about AMP. There are definitely pros and cons…

  • Very insightful! I spend so long setting up triggers to target specific clicks with Google Tag Manager, it’s nice to see how easily this can be avoided. I’ll send this to my web dev team for their perusal 🙂
