Improving a site’s mobile-friendliness apparently affects increasing domain authority.

“How mobile-friendly is it?” can be checked using Google’s official tool “Mobile-Friendly Test”.

For example, since 93% of sessions on this site are from PC, we haven’t made it mobile-compatible yet, but here are the results when I checked with the “Mobile-Friendly Test” shown in the screenshot below.

As expected, an alert message saying “Not mobile-friendly” is displayed along with various advice.

I want to clear all this advice, improve mobile-friendliness, increase domain authority, and expect SEO effects.

For now, this site will also work on mobile compatibility.

That’s all from the Gemba.
