Mobile Traffic to Index.php in Elgg Websites

Concerned about the Search Engine Google's last announcements about if your site is not cell phone and tablet friendly, then say good bye to that particular internet /app traffic. I checked the link to http://elgg.org/index.php and the results are exactly the same of my website:

Reasons this page is not mobile-friendly
Text too small to read
Mobile viewport not set
Links too close together.

You can try yourself and see what I'm talking about: https://www.google.com/webmasters/tools/mobile-friendly/ Check your site.

 How can we fix this major mobile problem and get the cell phones traffic to reach our sites?

Other than installing plugins that don't work and make the site even slower on the results.

I Appreciate your friendly response about solutions and ideas. My website is  ( The American Social Networks. )
