Tired of page speed as much as I am?
So many bloggers out there are stressing out about it, thinking their traffic will come to a standstill if they don’t get those green lights in Google’s PageSpeed Insights tool.
Yes, page speed is important, but there are so many other important things to worry about in the wonderful world of blogging.
That said, in this article I am going to show you how you can speed up your site with lazy loading in 5 minutes. Boom!
The Page Speed Story
In all seriousness, page speed is indeed a ranking factor. I think we can all agree on that.
But that doesn’t mean you need to chase that perfect score in the Google PageSpeed Insights tool in order to please Google and achieve higher rankings.
It doesn’t work that way, unlike what so many people want to believe.
The way I approach this whole page speed thing, is that I want to offer my readers a pleasant user experience. And page speed is one of the many factors that have an impact on the overall user experience.
The Google PageSpeed Insights tool is literally just that. It’s a tool. A tool that analyzes the content of a web page, and then generates suggestions to make that page faster.
Do you honestly believe that your keyword rankings will suddenly go up if your score increases by 20 points? I’ll eat my shoe if that is the case. The scores this tool spits out are not a ranking factor.
What this is about is user experience. The better your site’s user experience is overall, the more Google will appreciate your site in the long term. And a fast loading site contributes to a good user experience.
But there’s so much more. The layout and readability of your content, your site’s architecture, the amount of ads on your site, the size of your font, etc… All of these things + so much more, impact user experience.
And that is what your goal should be. To offer a good user experience to your readers. So that they will stick around on your site for longer, read more pages, and even come back later for more.
Your goal should NOT be to desperately chase those green lights. Your goal should NOT be to sacrifice other good user experience elements on your site just to earn a few extra speed points.
Now that we’ve put some context around page speed, let’s talk about one of the most effective ways to make your site’s pages load faster.
A common issue I see a lot of sites struggling with is image management. Images are often far too heavy, or there are simply too many of them in one page.
And this is why so many sites get a low score on the Google page speed tool.
Here’s an example:
This particular recipe blog post has around 20 images that are all in the 300-500 KB range, which is far too heavy.
Google also tells you how to fix that problem:
“Defer offscreen images”
This essentially means lazy loading, which means that images don’t load on the first page request. Instead, images load dynamically along with the user scrolling through your content.
I’d like to make a point here though, which is that you should optimize your images (by making them smaller, decompressing them) first, before starting with lazy loading.
Poor image management is in fact one of the most common blogging mistakes I see happening everyday.
How to Use a3 Lazy Load to Speed up Your Site
Some WordPress caching plugins, such as WP Rocket, include a lazy loading feature. But if you don’t want to invest in a premium caching plugin, you can choose to install a (free) lazy loading plugin.
The best one I’ve seen so far is a3 Lazy Load. It does the job of lazy loading perfectly, and comes with extra options to fine-tune the lazy loading experience for your readers.
Here’s the mandatory before and after page speed screenshots of an image heavy page on one of my sites:
It really does work. 🙂
1. Install a3 Lazy Load
The first step is to install the a3 Lazy Load plugin. Navigate to your Plugins section, click Add New, and search for a3.
Install and activate the plugin, then navigate to the settings.
2. Plugin Framework Global Settings
You can leave both these options set to OFF.
3. Lazy Load Activation
Set this option to ON to activate lazy loading on your site. This will also open up the rest of the settings.
4. Lazy Load Images
This section allows you to select what types of images you want lazy loaded. You can leave them all set to ON.
The Skip Images Classes is an interesting one. This allows you to exclude specific images from being lazy loaded by assigning a class to them.
For example, this can be useful for Pinterest images that are often located at the bottom of posts. If they’re lazy loaded, they can’t be pinned, because the social share button and also the Pinterest and Tailwind pin tools can’t see them until they’re loaded.
By assigning that specific class to these images, they won’t be lazy loaded.
5. Lazy Load Videos and Iframes
This allows you to lazy load videos and anything embedded in iframes.
If you’re using an ad network on your blog, such as Mediavine, it’s important to set this to OFF, because ads are typically rendered in iframes.
6. Exclude by URI’s and Page Types
This setting allows you to exclude specific pages or posts, or specific page types, from lazy loading. For example, you can choose to not have your home page lazy loaded.
7. Script Load Optimization
By default this setting is set to Footer, which means the lazy load script is loaded in the footer. If that doesn’t seem to work in your WordPress theme, set it to Header.
8. WordPress Mobile Template Plugins
You can leave these options set to ON.
9. Effect & Style
This option allows you to choose between a spinner or loader effect when your images are being loaded.
You can also configure a custom background color to show where your images are being loaded.
10. Image Load Threshold
This is another interesting setting you should play around with. This threshold determines when a3 should start loading an image. For example, if you set this to 200 pixels, an image will start loading as soon as a reader is 200 pixels above that image.
The higher you set this threshold, the less chance your readers will see any of the loading happening in real-time.
But you also don’t want to set this number too high, otherwise you’re defeating the whole purpose of lazy loading.
