Not having a mobile-friendly website is a crime against your business, blog or whatever it is that you are building.

If you spend most of your time optimizing your website. Making it look good. Making it fast. It is a wonderful thing. But the problem is that most of the time, you may actually make your site fast and good on desktop. And the mobile might not be so good or fast. With the help of mobile-friendly testing tools, you can measure your website’s performance on mobile.

Making your site fast and good looking on mobile is more important now than ever before. Because there are more people using mobile to access the internet than there are people using desktop according to statcounter.

It is also important for SEO. Google’s approach is now mobile-first indexing. What this means is that Google uses how your site looks on mobile for ranking and indexing. Even if your site is fast on desktop but slow on mobile, you may not get the ranking you deserve.

The two most important factors that will affect the speed of a website on mobile is hosting and the theme you are using. Here at BloggingTools, we use Cloudways for hosting. You can read my Cloudways review. If you cannot afford Cloudways then Bluehost or Hostinger are good options.

For theme we use GeneratePress because it is the fast theme around and very responsive. You can read my GeneratePress review. If you cannot afford the premium version, they have a free version, but I strongly recommend the premium.

Remember that a good web host and fast responsive theme is the foundation of a fast mobile-friendly website.
