How to optimize YSlow Score

Hi… After some optimize, my blog is get good score on GTmetrix.. but I found still low score for YSlow Score, please take a look at this image https://s10.postimg.org/lj5ljtm2h/Screenshot-2017-12-20_GTmetrix_Performance_Report_A_95_B_80.png. How to optimize “Add Expires headers and Minify” “JavaScript and CSS”? both are in high and medium priority.

Thank you

Add the expiration headers for your own content; you can’t do so for anything loaded from other sites.

You can minify the CSS and .js but a little tricky. See my long winded tutorial in the docs > tutorials > best of forums here for one way to do that.

Here is my .htaccess look like:

# BEGIN Expire headers
<ifModule mod_expires.c>
ExpiresActive On
ExpiresDefault “access plus 5 seconds”
ExpiresByType image/x-icon “access plus 604800 seconds”
ExpiresByType image/jpeg “access plus 604800 seconds”
ExpiresByType image/png “access plus 604800 seconds”
ExpiresByType image/gif “access plus 604800 seconds”
ExpiresByType application/x-shockwave-flash “access plus 604800 seconds”
ExpiresByType text/css “access plus 604800 seconds”
ExpiresByType text/javascript “access plus 604800 seconds”
ExpiresByType application/javascript “access plus 604800 seconds”
ExpiresByType application/x-javascript “access plus 604800 seconds”
#ExpiresByType text/html “access plus 600 seconds”
#ExpiresByType application/xhtml+xml “access plus 600 seconds”
</ifModule>
# END Expire headers

<IfModule mod_deflate.c>
<filesMatch “\.(js|css|woff|html|php)$”>
SetOutputFilter DEFLATE
</filesMatch>
</IfModule>

And I did minify CSS and js automaticly by CloudFlare

are those guides still relevant with the new updates in place? 🙂 thanks
