What is a QR code?

A QR code simply consists of a black square and dots (yeah). That, essentially, is what a QR code looks like. The pattern on QR codes can be alphanumeric, numeric, binary or Kanji (a form of Japanese character originated from China).

QR codes stand for Quick-response codes, which are two-dimensional barcodes containing data that point to a website or application.

The idea behind a QR code is to create an image that any mobile device can read (or scan) with a certain QR code scan application and transfer it to something meaningful.

What is a dynamic qr code?

In the development of QR codes, there are two types which were created:

Static QR Code. The destination site URL is placed directly into the QR code and can’t be modified. This QR code type is not as useful as the next one.

Dynamic QR codes. You use a short URL for the QR code which then re-directs users to your destination site URL. This short URL works like an intermediary that connects the code with the data. After the QR code has been generated, you can change the short URL.

(keep in mind that once a code is generated, it will permanently attached to the link)

Why are the dynamic QR codes much better than the static ones?

Let’s say if your boss is someone who always changes his mind about what link to use. Another example is if you want to use your website URL this week, your Facebook page the next week, and your Instagram page the other week, etc. These modifications make a lot of sense of the dynamic QR codes.

How do they work?

A QR code works similarly as a barcode in a supermarket, if you have a smartphone, you just need to scan it and can read the information that has been transferred.

Both Iphones and Android smartphones can scan QR codes directly from the main camera app.

You simply open the camera app and point it toward the QR code, it will “read” the code and show you a push notification

Basically, even with printed or online media, the point of QR codes is that they can be scanned by a touch of button by thousands of people around the globe using smartphones daily.

Therefore, you can think of QR codes as a wonderful means of accessing your website or other pages.

Well, you might ask why we don’t just type in a website name on your phone and visit it right away? So, the point of a QR code lay in its convenience.

Imagine that you are going for outside sales and you need your customers or potential clients to visit your website. You will not let them google your website name or type the URL in on their web browsers, instead, you use the QR codes to pass on business details to them.

How to make a QR code?

It’s pretty easy to create a QR code, there are 7 steps to make a QR codes:

Step 1: Choose a QR code generator

You might find your QR code generator from these lists:

  • Beaconstac QR Code Generator
  • The-qrcode-generator
  • QR Stuff
  • qr-code-generator
  • Kaywa QR codes
  • Create QR codes by Google app engine
Google QR codes generator

While choosing, you need to consider whether the code generator allows you to track and analyze performance of the QR code, and if it allows you to design a QR code that can represent your brand.

Step 2: Choose content you want to promote

After choosing a generator from one of the above, you will need to choose the content type. There can be URL, Text, Email, Social page, App, ect for you to choose.

Step 3: Enter data in the form appearing

Let’s choose the content type you’re gonna promote with the QR code, then you will see a form appearing where you fill in the information regarding your campaign.

Step 4: Consider downloading a dynamic QR code

Once you enter the information, you will see the option for choosing “dynamic”. If you want to use the dynamic QR code, just select it. Some generators allow you to use the dynamic QR code only with a free membership.

Step 5: Customize your QR code

This is an important step that affects your QR code campaign result. If. you want people to notice your Qr code, you need to make it standout and beautiful. With most QR generates, you can design your QR code with custom frames, your brand logo, a color palette and a CTA.

Because of the design and customization, your QR code can be hard to read. Use different QR code reader applications to check whether the code is scannable with them.

Also, don’t forget to check the destination that the code leads to.

Barcodes help retail stores in the checkout process, warehouses in tracking inventory, and accounting in managing invoices.

QR codes pros and cons

So, is using QR codes for marketing a good idea?

It’s probably a popular debate.

Some marketers look at the bright side of it, but others are skeptical about the effectiveness of QR codes and would rather invest in other things.

Now, we’re gonna look at the pros and cons of using QR codes as part of your marketing plan.

QR codes pros

Easy to produce

As mentioned above, you can easily create a QR code for your brand within 5 minutes. This helps you to spend your time solving other important questions such as where to print the code on or how to distribute it.

Can be placed anywhere

QR codes provide endless placement opportunities. They can be printed on different material such as paper, cloth or displayed digitally.

If you place an advertising banner somewhere on the internet, you can add the QR code there so your customers can visit your homepage, discount page, etc.

If you own a home furniture brand with an app, showcase your code outside the store to let busy customers visit your app simply by scanning it.

Appeal to curiosity

QR codes are tricky because you can’t see what you get until you scan it. You can use this mystery to ignite people’ curiosity and create excitement.

QR codes hide the content behind them

For example, you can say to online visitors that your brand is running a special gifting campaign and they should scan the QR code to explore the detailed program. And you can place this information on ads elsewhere on the internet.

Easily Trackeable

The tracking of QR codes is straightforward. Once a dynamic QR code is completed, it can be recorded.

You can track QR code usage data such as location, operating system (window, android, ios, ect.), traffic coming from the code, etc.

Some QR codes generators provide you with these kinds of data, however, you still need a more trustable source, we recommend you to use Google Analytics.

To see QR code visit information via Google Analytics, you just need Google Analytics code snippets added to your sites and the Google UTM string parameters added to your site URL.

For example: the link after being added with the Google UTM “” However, like we mention above, you should use the dynamic QR code with a short URL. So, you will shorten the long link above into a short one and store it in your QR code.
