Mobile Website Development: a Guide to Create an Easy-to-Use Site for Smartphones

The experts of our development agency have a solid foundation of mobile website development and want to share their expertise and explain the basic principles of search engine optimisation that your website should comply with.

How to Guide Mobile Traffic

In today's world focused on smartphones, the use of mobile devices exceeds the use of the desktop, and the development of sites optimized for mobile devices is essential for smartphone sites that are essential for all businesses. Let's get to the bottom of the problem. In key search engines like Google, there are three ways to determine if visitors will visit websites through desktop computers or through handheld devices.

Reactive development for smartphones and tablets: HTML has mobile and desktop websites, and the server defines what it wants visitors to see, depending on the device it uses. Dynamic delivery site: depending on the visitor's device, the URL shows different HTML and CSS. Different mobile sites: Desktop URLs have relevant web addresses related to smartphones, such as and, for example.

Which Option to Select?

It is necessary to dispel the myth that all mobile URLs start with "m", but it is not limited to this. You can use any top-level domain (google.mbl), subdomain or subfolder ( that is most suitable for the development of seb. Google reactively supports websites designed on other types, but each option has advantages and disadvantages, and it is up to you to decide which is the best.

Responsive Web Design

The websites designed in a corresponding way will send data to the server to see certain versions or different versions while looking at the configuration and the size of the server's display. The CSS3 media query used in this case also includes aspects such as display height, orientation, width and resolution. The CSS3 media query that Google recommends is "@media only screen and (max - width: 640px) {...}". Alternative CSS for small screens like iPhone and Android smartphones are included in brackets. At the time of development, the mobile version should be placed below the main CSS and overwrite the settings defined for the desktop computer.

  • cl1
  • cl2
  • cl3
  • cl4
  • cl5
  • cl6
Properties of Maximum and Minimum Width

Setting the maximum width property to 640px ensures that the device is oriented vertically or horizontally. For example, the iPhone has a width of 640px and a vertical size of 480px. It can be difficult, but in reality these pixel sizes are CSS pixels, not the actual pixel density of the smartphone. If you want to continue in detail, you can make the site correspond to the size of all the devices. Just set the interval between the minimum width and the maximum width at the development stage.

How to Hide Bulky Items

To detect the receptive website, we are using bots to see if it is optimized for smartphones through website images, CSS, Javascript. Therefore, you should not exclude robots with the robots.txt standard during web development. If you rearrange the elements on the page according to the different screen size, what happens if I have a sidebar on a part of the page? You can not allow such large elements on pages for mobile devices. There is a gap: simply use the "show: none" property for hidden text boxes and other elements. The content that is displayed on the larger screens will be hidden if it is minimized and replaced with links.

Web Development Tools: Pros and Cons

Designing a responsive site requires considerable knowledge of various IT technologies. If you're not a programming professional, you should hire a professional team of web developers. On the other hand, if you need a simple solution, you can use a web construction tool such as WP Touch for Wordpress. This allows smartphone users to provide a very basic version of a website optimized for their device. However, if a web development project is aimed at a wider audience, this tool is not the best option, since it can not provide the user with the superior experience.

Advantages and Disadvantages of Harmful Web Design


  • A URL is useful to share and remember
  • It is not necessary to redirect website visitors who use user agents, which minimizes the risk
  • The robot tracks the site only once. It does not verify all user agents. With this approach, you can index more resources and time for websites more efficiently


  • The content of the mobile page is similar to the content of the website (although this is rarely a problem)
  • To develop responsible sites, we need a lot of experience in tool and technology development. This is laborious and slow. Receptive design is a complicated development task and requires a lot of time and resources

Regardless of whether you are improving the responsiveness of smartphone sites or using other versions of smartphone sites, if you have an appropriate marketing campaign and the content is optimized for search engines, your ranking is impaired.

Dynamic Service Site Development

Dynamic service sites use the desktop version as the default, but the user agent detects the CSS and HTML that require the service according to the browser or device that the browser requests.

Therefore, user agents play an important role in dynamic services. Keep in mind, however, that detection by the user agent can lead to errors, as new smartphones appear on the market every day and it is impossible to include all models in the list of user agent chains. Therefore, it is likely that your list is not updated, as well as the mobile version of your website. Also, until it becomes popular, it can be very difficult to find the right user agent string for the smartphone you just launched. Our mobile website development experts will create such software, which will help you to collect new customers and increase ROI.

Advantages and disadvantages of dynamic service

To go to the dynamic publishing site, tell the search engine that there is hidden mobile content you need. It can be run on the server side using the variable HTTP response header. The advantages of this approach are the following:

  • Unique URL
  • You do not need to redirect users
  • And the disadvantages are the following:
  • Robots need to index many pages using several user agents
  • The redirection of the user agent is highly risky of errors

Mobile URL Website

The creation of a mobile version of a website means that each URL used on the desktop computer has a related page that contains content for smartphones. Once again, the server reads information about the user's device and redirects it to the appropriate version. The desktop version of each page of the site has the tag rel = "alternate" and the mobile version is shown in the

section. In this way, the search engine robot knows that there are pages optimized for mobile devices and also creates an index.

Advantages and Disadvantages of the Mobile URL


  • The URL website for mobile devices is designed natively for smartphones.
  • They are easier to build and implement.
  • An independent mobile website is designed to freely design all elements and functions, and to work intuitively even on small screens. We provide a highly responsive service or a dynamic service.


  • It is not efficient for tracking robots. This creates a risk that it becomes obsolete by the time the mobile version is indexed
  • Risk of errors during redirection
Use the Tag

Remember that the smartphone version inevitably requires a canonical label that leads to the desktop version. This will help you understand that the Google bot is two versions of a page and you do not need to index them separately. Otherwise, the mobile version is considered plagiarized, punished by the search engine, rel = canonical needs to be implemented on the mobile website, but rel = alternative can also be placed at the level of the site map. If Myth Busting Alert is implemented: rel = canonical, the use of two separate URLs does not result in link classification or scratch classification.

How will the User be Redirected to the Mobile URL?

By adding a rel = canonical tag to your website, break another myth without affecting the ranking of the search engine or causing link dilution. So, how does the browser redirect site visitors to the smartphone's URL? There are two ways to do it:

Redirect by HTTP according to the HTTP header

This method is slow because smartphones need to process the entire script before being redirected to the mobile version, but JavaScript redirection is necessary.
