How to improve the PageSpeed ​​of a site?

Question

htaccess

Hi all!
There is a site made on Wordpress, the site address is ecuras.com/. I'm currently trying to improve the PageSpeed ​​for this site. The indicators are bad.
The htaccess file contains the following block:

# SET ON BROWSER-SIDE CACHE
<ifModule mod_headers.c>
  <FilesMatch "\.(html|htm)$">
    Header set Cache-Control "max-age=43200"
  </FilesMatch>
  <FilesMatch "\.(js|css|txt)$">
    Header set Cache-Control "max-age=604800"
  </FilesMatch>
  <FilesMatch "\.(flv|swf|ico|gif|jpg|jpeg|png)$">
    Header set Cache-Control "max-age=2592000"
  </FilesMatch>
  <FilesMatch "\.(pl|php|cgi|spl|scgi|fcgi)$">
    Header unset Cache-Control
  </FilesMatch>
</IfModule>

<ifModule mod_expires.c>
  ExpiresActive On
  ExpiresDefault "access plus 5 seconds"
  ExpiresByType image/x-icon "access plus 30 days"
  ExpiresByType image/jpeg "access plus 30 days"
  ExpiresByType image/png "access plus 30 days"
  ExpiresByType image/gif "access plus 30 days"
  ExpiresByType image/webp "access plus 30 days"
  ExpiresByType application/x-shockwave-flash "access plus 30 days"
 
  ExpiresByType text/css "access plus 30 days"
 
  ExpiresByType text/javascript "access plus 30 days"
  ExpiresByType application/javascript "access plus 30 days"
  ExpiresByType application/x-javascript "access plus 30 days"
 
  ExpiresByType text/html "access plus 12 hours"
  ExpiresByType application/xhtml+xml "access plus 5 minutes"
  ExpiresByType application/xml "access plus 5 minutes"
</ifModule>

But Google still writes: Use browser cache
Why so? How to fix it?

Answer 1

The mod_headers.c, mod_expires.c modules may not be enabled on the hosting, that's why the cache does not work, you need to write to the hosting

Answer 2

The data for your site is taken from a third-party domain cdn.ecuras.com, so optimization must be done there too.
This applies to
1) Leverage browser caching. Copy the part of htaccess that deals with caching in htaccess on cdn.ecuras.com
2) Your images are not optimized. I have tried many online and offline utilities. I settled on TinyPNG for myself . It works with PNG, JPG files.
3) Reduce server response time. At this point, see which plugins can be disabled in WP. If possible, move to a more expensive hosting. But I don't think this point is critical.

Answer 3

well, do not forget to install it yourself jpegoptim
