The best way to make your WordPress blog mobile-friendly is to use a mobile-friendly theme from the WordPress theme directory.
Place the appropriate CTAs on your website and application so that, as people read your content, you can strategically direct them with actions to achieve the intended results.
By using the AMP plugin, you can make your website fast-loading and easy for mobile devices, even if your theme is not mobile-friendly.
The size of your blog also affects how well it will function on mobile devices. Use an ideal image size for your blog.
Mobile users won’t be able to read your blog if it’s too small, and vice versa if it’s too large. Choose an ideal font size for your blog.
