Mobile-friendly tools

Being mobile friendly is one of the most important things for Google search engine in 2017.

Given that majority of users access the web through mobile devices, it comes as a no surprise that you will have to have a responsive design on your site.

This change was in the making for quite some time.

In the last couple of years, the total percentage of mobile website visitors has surpassed the percentage of online desktop users.

This makes sense as people can find the same options on their mobile device as they can on regular computer and they don’t have to go home to check the latest news.

In terms of SEO, using a mobile-friendly testing tool can help you with blog content.

Recently, mobile sites and mobile-first index have become Google’s main priority and it should definitely be yours as well.

I will talk about tools to test your site’s mobile version in a bit.

However, before I do that, it is important to learn more about Google mobile and how this new approach affects websites.

Let me share some tips with you!

Importance of a mobile-friendly website for a user

So what are the main differences between desktop and mobile version of a URL?

Until recently, business owners would focus on desktop version of a site. The main issue is when a desktop page is converted to a mobile page.

Some websites are unable to render on mobile devices and you will get a screen full of misplaced links, broken formatting, broken text, etc.

In a nutshell, your user experience will go to hell.

On the other hand, sites that support mobile devices improve various aspects of user experience including:

  • Having larger, readable text that is presented in a proper way
  • Links are properly placed
  • Ability to navigate throughout the website without issues
  • User-friendly buttons
  • Faster loading and download speed

With a mobile-friendly website, every aspect of UX will be improved.

Thus users will be provided with approximately the same page as they would be if using a desktop device.

Mobile marketing and you

Next thing that needs to be considered is the actual impact of mobile marketing strategy on your business:

  • Website visitors are more likely to purchase products and services from their mobile device then they would from a desktop computer
  • If you have a mobile-friendly website, your overall user engagement stats will increase significantly which will (likely) help you rank higher in Google
  • Having a mobile-friendly website is not only important for conversion but the way you present your site to the general population. It improves brand perception as you will be seen as a professional company that thinks about its image

Although this isn’t much of a tip (given it has already become a common knowledge), I would still recommend that you should constantly pay attention to your mobile performance.

Together with the speed of your website, this is a ranking signal that will likely increase in important in future (or at least stay on the same level).

As such it will likely remain the backbone of your search engine optimization.

Mobile-friendly tools for your site

You can easily tell whether a page or a website is mobile optimized or not – all you have to do is open it in a browser.

However, fixing the situation is a completely different thing.

There are a lot of things that need to be considered and which usually revolve around:

  • Cash memory
  • HTML
  • Image optimization
  • CSS
  • Java Script
  • Server response speed
  • Layout of links
  • Text size and width
  • Plugins

As you can see, there is a lot to process.

Let’s check some of the best mobile-friendly tools that will help you make a website look good on mobile devices.

Google’s Page speed insights

This is one of the best tools on the market and a source of valuable information.

Like most Google tools it is completely free.

To make things even better, there is no need to sign in, to leave your email or some other data regarding your website.

All you need to do is place the URL of your homepage (or some internal page) and the tool will run its diagnostics.

It has 2 tabs: mobile and desktop.

This shows you how Google sees two different versions of your site.

Best thing about Page Insights is that it gives you a list of all the things that you should fix.

If the general explanation isn’t good enough, you can expand it and get some additional data that will guide you throughout the process.

Pretty cool!

Website Grader

This tool was created by Hubspot and gives a little bit different details in comparison to those provided by Google’s Page Insights.

It analyzes 4 main groups:

  • performance
  • SEO
  • mobile
  • security.

Have in mind that this tool is mainly advertised as a page speed tool. Nevertheless, its mobile section is more than enough for you to analyze whether a domain is responsive or not.

You have a score from 0 to 30 showing you how well your website performs.

Firstly, you can see how page looks from a mobile device. After that, the Website Grader analyzes how responsive it is and whether it is easy or not to resize it for various devices.

Although this information may seem rudimentary, they are good enough for a basic analysis.

Keynote MITE

Keynote MITE is a complete suite that offers various options to a user.

They mostly revolve around monitoring. Among various features, we also have mobile monitoring.

It offers a desktop app that will give you data regarding mobile performance.

If that wasn’t enough, there is also mobile monitoring where you can figure out how your audience is behaving.

Lastly, it analyzes all the errors that appeared on your mobile device.


According to description, iPhoney is primarily used to test how website design will look on a mobile platform.

The can check general compatibility.

It isn’t like Google’s Page Insights tool that analyzes website structure and gives you a detailed report but it still can help you with mobile optimization.

iPhoney is also a developers’ tool allowing you to create sites for mobile devices.


iPadPeek is a pretty straightforward tool.

You have a box in which you type name of your site and you will be shown how it looks on iPad.

You can scroll up and down to check the whole page. It looks pretty authentic with all the additional iPad elements.

For best results, it is recommended that you use Google Chrome or Apple Safari when performing the check.


SEOCentro is a complex tool that mostly resembles Page Speed Insights.

First, it gives you a general status of a website.

Here you can see data about response code, page content size, number of hosts, CSS and Java resources etc. Based on them, you can get a score from 0 to 100.

Then, you can see the main tips for mobile optimization and whether you’re doing them right:

  • size tap targets appropriately
  • avoid plugins
  • configure the viewport
  • size content to viewport
  • use legible font sizes

Besides each of these tips, there will be a notification telling you whether you did it properly or not; and if not, what you should change.

Lastly, you will see how the page looks like on a mobile device.

Mobile Friendly Test

Mobile Friendly Test by Small SEO Tools is precisely as advertised – it is small and simple.

Like all the other tools made by this company, you can use it directly on their site. All you need to do is enter targeted ULR into a box.

Unfortunately, there isn’t as much data for analysis as with some other tools.

Mobile Friendly Test will simply tell you whether or not site is optimized, it will give it a score and ultimately, show it the way it’s shown on a mobile device.

Rank Watch

Although not often mentioned with other top tools, Rank Watch is definitely a complete package SEO suite.

Mobile checker isn’t part of the suite and it goes separately. It is free and you can use it strength from the browser.

In terms of data provided, you will get a score with additional information regarding:

  • text size
  • closeness of links
  • width of content
  • compatibility of plugins
  • mobile viewport
  • website responsiveness

Rank Watch will analyze all the factors and show you whether or not you’ve implemented them properly.

Mobile-friendly bulk testing tool

This is probably one of the rare (if not the only) mobile checker tool that works with numerous URLs.

It was made by Merkle and it allows you to check various sites at the same time.

These addresses can be either entered manually, with copy pasted, or you can put them in a CSV file.

When it comes to analysis, it is rater basic.

Mobile-Friendly Bulk Testing Tool shows you whether a site is optimized or not and you can see how it looks on a mobile device.

Still, given that it is able to process numerous domains, this is software that some people can really benefit from.

To wrap it up

Mobile optimization will only grow in importance.

Regardless of what kind of a website you’re running, it is necessary for it to be optimized. If you don’t do it, you are risking of losing a lot of potential traffic in future.

Google page speed insights is great but there is only so much you can do to speed up a real estate website that displays homes listings. The photos and listings have to display correctly and this limits the speed optimization that can be done. It also limits the above the fold optimization

In my opinion, mobile-friendly by google is the best choice. The Mobile-Friendly test tool is easy to use; simply type in the full URL of the web page that you want to test. Any redirects implemented by the page will be followed by the test. The test typically takes less than a minute to run. Test results include a screenshot of how the page looks to Google on a mobile device, as well as a list of any mobile usability problems that it finds. Mobile usability problems are issues that can affect a user that visits the page on a… Read more »
