: Google Page speed test showing 0 page speed I tried to test the speed of a website and it appeared to show 0 speed. Why would a site have 0 speed? Please guide me. Thanks.

Following functions could help you hopefully a little on your way, because GTmetrix is also not that happy.

Remove query strings from static resources (?ver=x.x.x)
Text source Gtmetrix.com


Most proxies, most notably Squid up through version 3.0, do not cache
resources with a "?" in their URL even if a Cache-control: public
header is present in the response. To enable proxy caching for these
resources, remove query strings from references to static resources,
and instead encode the parameters into the file names themselves.


This function takes care of that, add to functions.php

function remove_version_parameter( $src ){
// Check if version parameter exist
$parts = explode( '?ver', $src );
// return without version parameter
return $parts[0];
}
// filter .js files
add_filter( 'script_loader_src', 'remove_version_parameter', 15, 1 );
// filter .css files
add_filter( 'style_loader_src', 'remove_version_parameter', 15, 1 );


Defer parsing of JavaScript files
Text source Gtmetrix.com


In order to load a page, the browser must parse the contents of all
tags, which adds additional time to the page load. By
minimizing the amount of JavaScript needed to render the page, and
deferring parsing of unneeded JavaScript until it needs to be
executed, you can reduce the initial load time of your page.


Following function takes care of that, add to functions.php

function add_defer_to_js( $url ) {

if ( FALSE === strpos( $url, '.js' ) ) {
return $url;
}

// Must be a ', not "!
return "$url' defer='defer";
}
}
add_filter( 'clean_url', 'add_defer_to_js', 11, 1 );


Just a note:


Do not resize your images with css, just make them the size as needed and add at least the width to them.
Take a look here for some information about how to do 'stuff'. (optimization)
Use the hints from other answers also and you will do pretty well afterwards.

Not to be rude, but because you score terribly for speed. Images thát big? Those images sizes are INSANE. Kinda harsh, but how did you even manage this?

To solve this, follow their suggestions as much as possible and your rank will increase. The list they give is a very good start.

You should at least:


Opitimize images. This is the first thing. Just drop your images in kraken.io, they'll do it for you. Save your images for web if you use Photoshop, don't just save as jpg.
Caching more than 24 hours, at least 1 week, I suggest you read about caching and best practices. Longer is better
Find a way to speed up your site. 4,8sec isn't doable in 2015 ;)
