How to increase your Blog page speed insights page speed
It doesn't take a genius to figure out that going mobile
 is the new norm these days. A mobile-friendly site is no longer a 
luxury, but a necessity. If you're working on making your website 
mobile-friendly, and haven't heard of PageSpeed Insights, then you know 
nothing! Google has put together (and now updated) a great tool - PageSpeed Insights - to help developers and webmasters make their pages mobile-friendly, with recommendations on mobile usability, and more.
It is the goal of any webmaster to optimize their website so as to 
minimize its loading time. A fast-loading page goes a long way in 
improving your website's user experience. But suppose you manage a very 
fast ~1 second load time for your website. If that comes at the cost of 
usability, then it's really not an improvement.
For example, a user might need to zoom out, or scroll down quite a bit 
in order to read the content on your site. The time wasted between the 
page loading, and up until the moment the user can start interacting 
with your website counts as much as the initial loading time. Well, this
 is where the PageSpeed Insights come in.
The PageSpeed Insights Tool provides valuable information regarding your
 website, and how you can optimize it for better effect. It's new 
user-experience rules can help you find and fix the usability issues 
found on your website.
Usability recommendations
Google has recently updated the tool with some new recommendations, a summary of which is given below.
1. Viewport
Without a meta-view port tag, modern mobile browsers will assume your 
page is not mobile-friendly, and will fall back to a desktop viewport 
and possibly apply font-boosting, interfering with your intended page 
layout. Configuring the view port to width=device-width should be your 
first step in mobilizing your site. (More on the topic coming up, so 
stay tuned!)
Size content to the view port: Users expect mobile sites to scroll 
vertically, not horizontally. Once you've configured your view port, make
 sure your page content fits the width of that view port, keeping in mind
 that not all mobile devices are the same width.
2. Font sizes
Use legible font sizes: If users have to zoom in just to be able read 
your article text on their smartphone screen, then your site isn't 
mobile-friendly. Page Speed Insights checks that your site’s text is 
large enough for most users to read comfortably.
3. Scale objects
Size tap targets appropriately: Nothing’s more frustrating than trying 
to tap a button or link on a phone or tablet touchscreen, and 
accidentally hitting the wrong one because your finger pad is much 
bigger than a desktop mouse cursor. Make sure that your mobile site’s 
touchscreen tap targets are large enough to press easily.
4. Avoid third-party plugins
Avoid plugins: Most smartphones don’t support Flash or other browser 
plugins, so make sure your mobile site doesn't rely on plugins.
