“Really? We’re talking about QR codes?”
Fair reaction. For several years now, QR codes have been at the center of the popular “___ is dead” trope we marketers love to argue when talking technology. We’ve even debated it ourselves on this blog.
But if there’s one thing the QR code debate shows you, it’s that there sure isn’t a consensus — the efficacy of QR codes still hotly contested.
Nonetheless, there’s no denying the popularity and convenience of the QR code. Keep reading to learn how to create your own QR code, and how you can encourage your customers to scan them when they come across your content.
What Is a QR Code?
QR codes, short for “quick response” codes, are square-shaped black-and-white symbols that people can scan using a smartphone to learn more about a product.
These encrypted squares can hold links, coupons, event details, and other information that users might want to take with them for referring to later.
QR codes usually look something like this:
Although not every QR code is shaped like a perfect square, they’re most often found looking like the image above — with varying patterns displayed inside. You’ll often find them on direct mail, signage, billboards, and even commercials where you can quickly scan the code on the screen using your phone.
QR Codes vs. Barcodes
Does the rise of QR codes mean traditional barcodes are a thing of the past? Of course not. Traditional barcodes are still a common way for businesses to identify consumer packaged goods (CPGs) and manage their product inventory.
However, there are a number of differences between barcodes and QR codes — both in their uses and their characteristics. Here are three important differences:
QR Codes Are Shaped Differently
Barcodes are typically rectangular in shape, requiring scanning devices to read the barcode’s data horizontally. QR codes are often square-shaped, displaying their data vertically or horizontally.
QR Codes Hold More Data
Due to a QR code’s square shape, it can hold much more data than a barcode. In fact, QR codes can hold hundreds of times more encrypted characters than a barcode.
QR Codes Hold Different Data
QR codes are often used differently than barcodes. Barcodes hold key product information at the point of sale, such as the price and name of the manufacturer. QR codes offer more passive and intangible information, such as location data and URLs to promotions and product landing pages.
How Do QR Codes Work?
Originally designed in Japan for the automotive industry, marketers adopted the barcodes because of their large storage capacity and ability to translate additional information to consumers beyond what creative and/or packaging could convey.
If a consumer sees a QR code somewhere, they can take out their mobile device, download a free QR code scanning app, and “scan” the barcode to gain access to additional information, like so:
So if you wanted to create, say, a bus stop advertisement promoting your podcast, you could display a QR code on that printed ad that brings people right to your iTunes page when they scan it with their phones. Pretty simple, right?
How to Make a QR Code
The QR code creation process is pretty straightforward. Here’s how to get started.
Step 1: Select a QR code generator.
There are tons of QR code generators out there. The best ones give you many options for using your QR code, and compatibility with most mobile QR code reader apps.
Best QR Code Generators
- Free QR Code Generator by Shopify
- QR Stuff
- QR Code Monkey
- Create QR Code by Google App Engine
Other things to look for when choosing a QR code generator are whether you can track and analyze performance, and if it allows you to design a code that’s unique to your brand.
Some QR codes, for example, display logos and other icons within the code that immediately tell people what information they’ll get from scanning it.
Step 2: Choose the type of content you’re promoting.
Let’s select one of the QR code generators above and do a walk-through together. I’ll select qr-code-generator.com, one of the eight preferred QR code generators above.
First, select what type of content you want your QR code to show the person after they scan it. You can choose from one of 10 types, as shown in the screenshot below. For our purposes, we’ll promote a URL that directs users to our podcast.
Step 3: Enter your data in the form that appears.
Once you select the type of content you’re promoting with this QR code, a field or form will appear where you can enter the information that corresponds with your campaign.
If you want your QR code to save contact information, for example, you’ll see a set of fields where you can enter your email address, subject line, and associated message.
To save a link to our podcast, we’ll simply enter the URL in the field that appears, like so:
Step 4: Consider downloading a dynamic QR code.
See the option below for “dynamic”? One significant pitfall to making a QR code is that you can’t edit the data it contains once you print it. But with dynamic QR codes, you can edit this data.
With a free membership to QR code generators like qr-code-generator.com, you can print a dynamic QR code, scan it, and pull up an editable form where you can modify the data your visitors will receive when they scan the QR code themselves.
Step 5. Customize it.
The fun part of creating QR codes is customizing the design of the codes to your brand. Want your code to look like your logo? Go for it. Want it to reflect your website’s design scheme? No problem.
Using qr-code-generator.com, we can customize our QR code by clicking the button to the top-right, as shown in the screenshot below. Keep in mind not every QR code maker offers this design option — depending on the QR code you’re looking to generate, you might find some tools limited in their functionality.
Of course, you can customize your QR code further — adjusting the colors, adding a logo, creating social options, and more.
Keep in mind, however, that some customizations can make it more difficult for QR code scanning apps to properly read the code. It’s a good idea to generate two versions of your QR code — one plain version and another with your preferred design.
Step 6: Test the QR code to make sure it scans.
Because a customized QR code can make it difficult for some mobile apps to “read,” don’t forget to check to see if the QR code reads correctly, and be sure to try more than just one reader. A good place to start is the free tool Google Goggles, which takes a picture and then tells you what link or item it “reads to.”
Another great free tool is QR Code Reader, which automatically takes you to whatever it “reads.” Apple’s Passbook also offers a built-in QR code reader on iOS 7, so you should test to make sure your code is readable there, as well.
Step 7: Share and distribute the QR code.
A QR code won’t be able to do its job unless its seen. So make sure you come up with a distribution plan for sharing the code. This could include displaying it on social media, in print ads, on clothing, or in physical locations where people will pick up there phones to scan it.
Along with sharing the code, you might also want to include text instructions in your various promotions that show less tech-savvy people how to scan it. This way there’s no friction if people want to scan the code but don’t know how to.
Scroll down for more tips on properly displaying a QR code.
Step 8: Track and analyze performance.
Just like any marketing campaign, you should follow up on any collateral or campaigns using QR codes to see whether they’re actually working. How much traffic comes from each specific code? Are people scanning your code but not redeeming their offer once they get to the landing page? Or are they not even compelled enough to scan your QR code?
Knowing this will help you troubleshoot and adjust your poorly performing QR codes to more closely mirror those that work well. I recommend you include a UTM tracking code on your URL so you can better measure performance — this is particularly important if you use closed-loop marketing analytics, and are used to more in-depth reporting on your campaigns.
How to Use QR Codes (And How Not to)
Now that you see how simple the QR code creation process can be, let’s talk about some best practices that’ll help increase the likelihood your QR code actually gets used.
Put QR codes in places where scanning is easy, and there’s enough time for the consumer to actually scan the code. While you may often see QR codes on billboards and TV commercials, they’re not exactly the most user-friendly locations. Think of places and mediums where consumers have the time to scan the code, and, ideally, a Wi-Fi connection as well.
Optimize the QR’s destination page for mobile devices.
Mobile-optimize the page to which you’re sending people. Consumers will be on their phone when scanning the QR code, so they should be brought to a page with a positive mobile experience.
Include a CTA that prompts people to scan your QR code.
Offer a call-to-action (CTA) with the code — that is to say, tell people what they’re supposed to do when they see the code, and what they’ll receive if they do it. Not everyone knows exactly what a QR code is, and those that do won’t be motivated to scan it unless they’re sure there’s something worthwhile on the other side.
Don’t limit your QR code to one mobile scanner.
Don’t require a special QR code scanner. Your QR code should be app-agnostic so anyone can scan your code with any reader. A lower barrier to entry makes success more likely for you and the user.
Use your QR code to make someone’s life easier.
Don’t use a QR code just for the sake of using one. For instance, it’s common for marketers to think, “How can I bridge the offline experience with the online experience? Uhhh … QR code!” That’s not wrong … but it’s not always right, either.
If you have content that makes sense to deliver to a mobile user, and you have an appropriate channel to do it (see use #1 at the beginning of this section), it’s more likely your QR code will drive results. For example, in South Korea, grocery store chain Tesco drove tremendous national business growth by using QR codes in subway stations (I guess they have mobile service in their subway stations) to let riders order their groceries while they wait. It’s a great example of using QR codes for the right end-goal, at the right place and time.
If after reading this you’re not convinced QR codes are the right move — or you just want some additional ways you can connect the offline world to the online world — consider also adding a short, memorable URL people can type in easily on their mobile phones in your creative.
The future of QR codes could also mean an evolution — augmented reality apps certainly stem from the same concept, after all. Consider the AR News App, which lets readers augment a newspaper story into a child-friendly article by downloading an app and hovering over stories with a special marker (sounds pretty close to a QR scanner, doesn’t it?).
It may be that QR codes aren’t quite dead, but just the first step in a long evolution.

Step 1: Use the URL inspection tool to see if Google can render your content
The URL inspection tool (formerly Google Fetch and Render) is a great free tool that allows you to check if Google can properly render your pages.
The URL inspection tool requires you to have your website connected to Google Search Console. If you don’t have an account yet, check Google’s Help pages.
Open Google Search Console, then click on the URL inspection button.
In the URL form field, type the full URL of a page you want to audit.
Then click on TEST LIVE URL.
Once the test is done, click on VIEW TESTED PAGE.
And finally, click on the Screenshot tab to view the rendered page.
Scroll down the screenshot to make sure your web page is rendered properly. Ask yourself the following questions:
- Is the main content visible?
- Can Google see the user-generated comments?
- Can Google access areas like similar articles and products?
- Can Google see other crucial elements of your page?
Why does the screenshot look different than what I see in my browser? Here are some possible reasons:
- Google encountered timeouts while rendering.
- Some errors occurred while rendering. You probably used some features that are not supported by Google Web Rendering Service (Google uses the four-year-old Chrome 41 for web rendering, which doesn’t support many modern features).
TL;DR: What is robots.txt?
It’s a plain text file that instructs Googlebot or any other search engine bot if they are allowed to request a page/resource.
Fortunately, the URL Inspection tool points out all the resources of a rendered page that are blocked by robots.txt.
But how can you tell if a blocked resource is important from the rendering point of view?
You have two options: Basic and Advanced.
In most cases, it may be a good idea to simply ask your developers about it. They created your website, so they should know it well.
Obviously, if the name of a script is called content.js or productListing.js, it’s probably relevant and shouldn’t be blocked.
Unfortunately, as for now, URL Inspection doesn’t inform you about the severity of a blocked JS file. The previous Google Fetch and Render had such an option:
Now, we can use Chrome Developer Tools for that.
For educational purposes, we will be checking the following URL: http://botbenchmarking.com/youshallnotpass.html
Open the page in the most recent version of Chrome and go to Chrome Developers Tools. Then move to the Network tab and refresh the page.
Finally, select the desired resource (in our case it’s YouShallNotPass.js), right-click, and choose Block request URL.
Refresh the page and see if any important content disappeared. If so, then you should think about deleting the corresponding rule from your robots.txt file.
To diagnose it, in the URL Inspection tool click on the More info tab.
Then, show these errors to your developers to let them fix it.
Your website may work fine in most recent browsers, but if it crashes in older browsers (Google Web Rendering Service is based on Chrome 41), your Google rankings may drop.
Need some examples?
- A single error in the official Angular documentation caused Google to be unable to render our test Angular website.
- Once upon a time, Google deindexed some pages of Angular.io, an official website of Angular 2+.
Step 4: Check if your content has been indexed in Google
It’s not enough to just see if Google can render your website properly. You have to make sure Google has properly indexed your content. The best option for this is to use the site: command.
It’s a very simple and very powerful tool. Its syntax is pretty straightforward: site:[URL of a website] “[fragment to be searched]”. Just take caution that you didn’t put the space between site: and the URL.
Let’s assume you want to check if Google indexed the following text “Develop across all platforms” which is featured on the homepage of Angular.io.
Type the following command in Google: site:angular.io “DEVELOP ACROSS ALL PLATFORMS”
As you can see, Google indexed that content, which is what you want, but that’s not always the case.
- Use the site: command whenever possible.
- Check different page templates to make sure your entire website works fine. Don’t stop at one page!
If you’re fine, go to the next step. If that’s not the case, there may be a couple of reasons why this is happening:
- Google still didn’t render your content. It should happen up to a few days/weeks after Google visited the URL. If the characteristics of your website require your content to be indexed as fast as possible, implement SSR.
- Google encountered timeouts while rendering a page. Are your scripts fast? Do they remain responsive when the server load is high?
- While indexing, Google may not fetch some resources if it decides that they don’t contribute to the essential page content.
Step 5: Make sure Google can discover your internal links
There are a few simple rules you should follow:
- Google needs proper <a href> links to discover the URLs on your website.
- If your links are added to the DOM only when somebody clicks on a button, Google won’t see it.
As simple as that is, plenty of big companies make these mistakes.
Proper link structure
Googlebot, in order to crawl a website, needs to have traditional “href” links. If it’s not provided, many of your webpages will simply be unreachable for Googlebot!
I think it was explained well by Tom Greenway (a Google representative) during the Google I/O conference:
Please note: if you have proper <a href> links, with some additional parameters, like onClick, data-url, ng-href, that’s still fine for Google.
A common mistake made by developers: Googlebot can’t access the second and subsequent pages of pagination
Not letting Googlebot discover pages from the second page of pagination and beyond is a common mistake that developers make.
When you open the mobile versions for Gearbest, Aliexpress and IKEA, you will quickly notice that, in fact, they don’t let Googlebot see the pagination links, which is really weird. When Google enables mobile-first indexing for these websites, these websites will suffer.
How do you check it on your own?
If you haven’t already downloaded Chrome 41, get it from Ele.ph/chrome41.
Then navigate to any page. For the sake of the tutorial, I’m using the mobile version of AliExpress.com. For educational purposes, it’s good if you follow the same example.
Open the mobile version of the Mobile Phones category of Aliexpress.
Then, right-click on View More and select the inspect button to see how it’s implemented.
As you can see, there are no <a href>, nor <link rel> links pointing to the second page of pagination.
There are over 2,000 products in the mobile phone category on Aliexpress.com. Since mobile Googlebot is able to access only 20 of them, that’s just 1 percent!
That means 99 percent of the products from that category are invisible for mobile Googlebot! That’s crazy!
These errors are caused by the wrong implementation of lazy loading. There are many other websites that make similar mistakes. You can read more in my article “Popular Websites that May Fail in Mobile First Indexing”.
TL;DR: using link rel=”next” alone is too weak a signal for Google
Note: it’s common to use “link rel=”next’ to indicate pagination series. However, the discoveries from Kyle Blanchette seem to show that “link rel=”next” alone is too weak a signal for Google and should be strengthened by the traditional <a href> links.
John Mueller discussed this more:
“We can understand which pages belong together with rel next, rel=”previous”, but if there are no links on the page at all, then it’s really hard for us to crawl from page to page. (…) So using the rel=”next” rel=”previous” in the head of a page is a great idea to tell us how these pages are connected, but you really need to have on-page, normal HTML links.
Don’t get me wrong — there is nothing wrong with using <link rel=”next”>. On the contrary, they are beneficial, but it’s good to combine these tags with traditional <a href> links.
Checking if Google can see menu links
For the purpose of the tutorial, we will use the case of Target.com:
To start, open any browser and pick some links from the menu:
- https://www.target.com/c/clothing/-/N-5xtd3 -> Clothing
- https://www.target.com/c/shoes/-/N-55b0t -> Shoes
- https://www.target.com/c/furniture/-/N-5xtnr -> Furniture
Next, open Chrome 41. In the Chrome Developer Tools (click Ctrl + Shift + J), navigate to the elements tab.
The results? Fortunately enough, Google can pick up the menu links of Target.com.
Now, check if Google can pick up the menu links on your website and see if you’re on target too.
Step 6: Checking if Google can discover content hidden under tabs
I have often observed that in the case of many e-commerce stores, Google cannot discover and index their content that is hidden under tabs (product descriptions, opinions, related products, etc). I know it’s weird, but it’s so common.
It’s a crucial part of every SEO audit to make sure Google can see content hidden under tabs.
Open Chrome 41 and navigate to any product on Boohoo.com; for instance, Muscle Fit Vest.
Click on Details & Care to see the product description:
“DETAILS & CARE
94% Cotton 6% Elastane. Muscle Fit Vest. Model is 6’1″ and Wears UK Size M.“
Now, it’s time to check if it’s in the DOM. To do so, go to Chrome Developers Tools (Ctrl + Shift + J) and click on the Network tab.
Make sure the disable cache option is enabled.
Click F5 to refresh the page. Once refreshed, navigate to the Elements tab and search for a product description:
As you can see, in the case of boohoo.com, Google is able to see the product description.
Perfect! Now take the time and check if your website is fine.
If you are still struggling with Google ranking, you might want to think about implementing dynamic rendering or hybrid rendering. And, of course, feel free to reach out to me on Twitter about this or other SEO needs.
