PageSpeed ​​Score

The grade that Google gives to the performance of the web. Very important.

YSlow Score

The note was given by Yahoo. Less important if your positioning objective is Google.

Here is another important piece of information: the Time to First Byte, which is the time it takes for the hosting to offer the first byte of the web page.

How to improve these metrics? GTMetrix recommendations and solution + tricks to fully optimize WordPress for SEO.

Apart from these essential metrics, GTMetrix offers us a super useful list of the elements that are worsening to optimize WordPress performance.

Taking as a reference the optimization work carried out with the A***-** website, I am going to explain them to you one by one and I am going to tell you how we did to optimize each one of them.

If you look at the previous image, you can see that we started with a PageSpeed ​​Score of 70, a YSlow of 60, a loading time of approximately 5 seconds, page size 1.51 MB and 131 Requests.

Apart from this, we had room for improvement related to various code elements of the template, plugins, etc. Why was this happening?

When you install a WordPress template and design your website, install plugins, etc., it is normal that you find similar metrics if you have not yet performed the optimization. Now I am going to tell you in detail how we optimize all these points:

1. Optimize WordPress images 63%. The solution

31 Simple Hacks to Optimize WordPress for SEO

 

This problem was due to the lack of optimization of some images. When you work on your website, sometimes the stress of day to day makes you forget about this essential aspect and you upload your images too heavy.

How to optimize the weight of the images? Solution for Optimize WordPress Images

You have several ways to tackle this problem quickly, easily and for free.

We did it in a super simple way thanks to the optipng tool that  Hostinger offers for free. With a single click and in a few minutes, our images were perfectly optimized. That easy.

You can see the difference between premium hosting such as  Hostinger and other lower-quality hostings and services. They are not gambling with this.

In this image, you can see the before and after of the optimization. As you can see, by improving the optimization of images from 63% to 99%, they improved the essential metrics of the web, especially the PageSpeed ​​Score.

Other ways to optimize WordPress images are:

  • Plugins. WP Smush It. EWWW Optimizer. Free plugins that allow you to optimize the images of a website. It is a little slower than the previous one and the result is not so good, but it is a good solution if you do not have premium hosting.
  • Tools like Tiny PNG or JPG Mini. Free online applications that allow you to greatly optimize the weight of the images. The downside is that you have to download the images, run them through the tool and then upload them again.

2. Combine images using CSS Sprites 0%. The solution

This GTMetrix recommendation refers to the use of sprite images to reduce the number of requests and improve the loading speed.

What is a sprite?

It is an image file that contains many images from the site in a single file, so instead of uploading several files, just upload one. Then, with CSS, you move the coordinates of the image so that in each case a different one is displayed.

Why did we have this problem?

On our website, we have a mega menu type main menu, with a multitude of sections with icons. To load each icon, the web requests the server’s images folder, slowing down the load a lot and worsening the performance metrics.

 

Solution. How to fix the Combine images using CSS Sprites?

1. Generating a single image that contains all the icons in a single file

2. Putting the image as a background to all the icons and moving it 40 pixels to the left for each one using CSS

For the second icon, in background-position we put -40px 0px; For the third, we put -80px 0px; And so on.

The first value refers to the horizontal x-axis of coordinates, and the second to the vertical y-axis. Each icon shifts its background image 40 pixels to the left and in each case, a different image appears even if it is the same file.

Here you can see the before and after optimization using sprites. The improvement was brutal, from 75% to 83% in PageSpeed ​​Score and a second less loading time. See how requests went down from 136 to 105.

3. Leverage Browser Caching 75%. How to solve it

This notice indicates the need to increase the caching of web elements to improve their loading to speed up a website.

How to improve the cache of a WordPress website? There are two possible cases

3.1. If GTMetrix tells you that the URLs to cache are internal to your website

  1. Installing cache plugins. The best ones, in my opinion, are WP Rocket (paid) and W3 Total CacheWP Rocket is a spectacular plugin whose price is nothing compared to what you get. I use it in all my projects and the difference is remarkable

 

  1. Hiring a good hosting. host like Hostinger or Bluehost implements an advanced cache system like Magic Cache (based on Varnish Cache) that improves load times considerably.

3.2. If GTMetrix asks you to cache URLs of external services

To cache external URLs like Analytics, Fonts, Maps, Facebook Event, etc., the process is a bit more advanced and requires the help of an expert in web code. The step-by-step procedure is as follows:

  1. Display in GTMetrix the box that warns you about the cache and sees which external files it asks you to cache. Save the codes that these external files contain in internal files on your hosting.
  2. It creates a script that runs with a cron task (scheduled task) every x hours, which saves the updated versions of the scripts of these external services in a directory.
  3. Edit the header.php file and change the URLs of the codes so that the calls to these files are made to those that you have uploaded to your own hosting and are loaded locally.

The before and after optimization shows an improvement in PageSpeed ​​from 83% to 87% and improvements also in YSlow Score, loading speed and page size.

4. Serve Scaled Images 79%. The solution

Another problem that GTMetrix warned us about was loading images at sizes larger than necessary, something quite common on web pages.

This warning can have two different causes :

  1. You have manually uploaded the images to a larger size than necessary. For example, for a 300-pixel wide box, you have uploaded an image at 600px.
  2. Your template is displaying the images unnecessarily larger in size automatically. For example, you have on the home page of your website a strip divided into three columns with the last three blog articles.
    The header images of each post, despite being displayed at a smaller size than the original, are still the same as the one you uploaded at a width of 900px since the template is not showing the previously rescaled images.

How to fix Serve Scaled Images?

  1. If you have uploaded the images to a larger size than you should, optimize them. You can do this by downloading the images, resizing them with a program like Photoshop or free online applications like Photor. Or much easier, with a free plugin like Photo Editor
  2. If the problem is with your template, with a free plugin like Regenerate Thumbnails you can define the exact sizes that the images should have in the various places on your web page. Next, by tapping your template code a bit, you command it to display these exact sizes on each site.
  3. Using SVG vector type images. This type of image, being vector, always offer maximum quality and, if you optimize them well when you generate them vectorially, they can weigh less. A priori WordPress does not allow uploading vector images, but with a free plugin like SVG Supportyou can do it easily.

Once this improvement was made, we raised PageSpeed ​​Score to 88% and we continue to improve in the other parameters to optimize WordPress for SEO and Speed up a website.

5. Defer Parsing of Javascript 54%. How to improve it

Too many requests to Javascript files in the header of the page. This is a typical problem of many WordPress templates that are not very well optimized and that include a huge number of JS files.

How to fix Defer Parsing of Javascript?

1. Merging files

If what we want is to reduce calls to Javascript files, one way to do it may be by reducing the number of JS files.

You can do this by merging files with a plugin like WP Rocket, which, as we have already mentioned, is paid.

A free alternative is the JS & CSS Script Optimizer plugin.

Note: as long as you do file merging, see below that your website continues to function correctly. Depending on the template and plugins installed, the result may vary.

2. Elimination of requests to Javascript files

This must be done manually, editing the code of your template, which requires a little knowledge of web programming.

The files of your website can be edited via FTP, file manager of the hosting panel or directly from your WordPress administration panel, in Appearanc> Editor.

To do this, go to the header.php file of your template, which dynamically generates the HTML header of your website (it is the portion of code that goes between the <head> </head> tags).

Sometimes templates make requests to Javascript services that you don’t need. If this is the case, delete these requests. 

Another solution can be to take some requests to the footer of the page. This prevents charging from occurring in the first place.

In both cases, always do it with knowledge and great care to avoid problems on your website.

3. Asynchronous loading

Asynchronous or lazy loading allows you to call files in parallel, as long as they are files that are not immediately necessary to load your website.

Thus, you reduce requests to Javascript files in the initial load of your website and avoid the bottleneck.

Asynchronous loading can be done with WP Rocket. As you can see, we have already listed several improvements that can be solved with WP Rocket, which justifies your purchase.

If you optimize many things with a single plugin, you avoid installing too many plugins, with the problems that this can lead to weight, maintenance and possible conflicts.

However, if you prefer to do it for free, you have the Async Javascript plugin.

Notice how this Javascript optimization has significantly optimize WordPress performance of our website by drastically reducing requests or requests from 105 to 72. This allowed us to raise the PageSpeed ​​Score to 92% and lower loading times.

 6. Remove Query Strings from Static Resources 61%. Easy fix

Another typical problem of many WordPress templates, related to the generation of unnecessary strings in certain requests. It is not very serious and it is also easy to solve. By cleaning these text strings you can improve caching and speed.

How to fix Remove Query Strings from Static Resources?

Very simple mode

With a plugin like WP Rocket. Once again, this plugin allows us to fix a problem without having to install a different plugin for each enhancement.

If you want to do it for free, you have this plugin.

Advanced mode

Editing the functions.php file of your template and inserting this code

31 Simple Hacks to Optimize WordPress for SEO

The optimization of the Query Strings allowed us to raise the PageSpeed ​​Score a bit to 93% and slightly improve other metrics to completely optimize WordPress for SEO & speed up a website.

7. Lazy Loading. How to optimize WordPress images loading to Speed up a Website

Lazy image loading is about serving images progressively across the page, not all at once. On a page loaded with many images, it can be very useful to lower page size and requests.

This is not a specific problem that GTMetrix warns us about, but it is essential to improve a key aspect to optimize WordPress performance: the number of requests or requests.

How to Lazy Loading Images

With a plugin like WP Rocket (another one!).

To do it for free, you have two very good alternatives. BJ Lazy Load or Speed ​​Booster Pack.

As you can see in the graph, by implementing this improvement we lowered the number of requests from 72 to 37. Thanks to this, all other metrics improved, achieving a PageSpeed ​​of 94%.

8. Server cache. How to optimize caching

As I mentioned at the beginning, correct caching by your hosting can be a crucial element to optimize WordPress for SEO and speed up a website.

Apart from the cache improvements that plugins like WP Rocket or W3 Total Cache can implement, there is a part that your server must do. Having premium hosting like Hostinger can be decisive to improve your metrics and have a good SEO in Google.

Our Hostinger hosting performs a cache using a tool called  Magic Caché (based on Varnish Caché). Varnish Cache is an advanced RAM caching system, which reduces load times and improves First Byte.

 

What is in my opinion the best hosting for WordPress?

I always say it, but in this case with even more reason: having good hosting can be crucial for your business on the internet. Don’t play it with this.

One of the best WordPress hostings I’ve tried

Hostinger

A quality hosting like Hostinger allows you to achieve higher loading times than other lower quality hostings, not to mention its enormous security, excellent support and stability.

Almost all our projects are hosted on this hosting and we could not be more satisfied. If you want your website to have a high speed and work in a professional, it is worth the difference in optimizing WordPress performance and speed once the Magic Caché tool from Webempresa has been passed to our website.

despite all the improvements implemented and being aware of the difficulty of further improving the metrics, from 94%  we went up to 96% of PageSpeed ​​Score. From 1.7 seconds of loading speed, we dropped to 1.2 seconds.

 

Note:  Another high-quality hosting that I use on this website that you are reading is BlueHost, specifically the optimized VPS service that offers brutal speed and optimize WordPress performance and that helps me to position myself in the top positions of Google.  

 

The final result of the optimization of our WordPress website

In the following graph, you can see the global comparison once all the optimization actions have been carried out on our website.
