Website optimisation

I persuaded my client to sign up for WPMUDEV yesterday on the basis that I would get his site humming along speedwise.

I went throught he whole process eventually getting this message from your team: "admin, you've smushed 1705 images and saved 14.7 MB in total"

The Google page speed results still suggest I compress a bunch more images!??

But when I did a Google page speed test on it the results were terrible. Much worse than anything else I've ever produced.

I'm clearly missing something but if you could advise me asap I'd be grateful - my client is expecting a much improved update later today!!!

The site in question is

    Hello there Jem Rose,

    hope you're doing good and thanks for reaching us! :slight_smile:

    Getting a high score in Google PageSpeed includes many parameters, which can been seen in their results or in our HummingBird plugin (specifically in the Performance Report module it includes)
    which is our speed-improvement plugin, apart from Smush of course.

    So, scanning your website with Google PageSpeed reveal to us what should be made now:
    1. Optimize images

    There are some images that needs compressing. These are full-size images, as they don't have any kind of specific thumbnail size as suffix to their filenames. Smush plugin doesn't compress full-size images by default, so in order to do that, you should go to its settings and enable the "Smush my original full-size images" (you may also want to activate the "Make a copy of my full size images" with that) and bulk smush your images again.

    2. Eliminate render-blocking JavaScript and CSS in above-the-fold content

    In order to surpass that, you should activate HummingBird plugin, if not already, and also activate the Minification module from it. After doing so, you will see a complete list of your assets, locate the reported CSS file and try to enable the "footer" and/or "inline" options for it. Then check homepage that all is good, if not, revert the changes and skip this from the report.
    More info about this part of optimization can be found here:

    3. Leverage browser caching
    The reported files are not coming from your server, so you can't control their browser caching expiry settings.

    4. Minify CSS
    5. Minify JavaScript

    Again for these two, you will need to activate HummingBird's Minification and select the "minify" option for all of your assets.
    If this results to broken parts in your site (this can be happening from bad coded plugins/themes or conflicts between them), then you should revert changes one by one, until you have a good working site with as many as possible minified assets.
    More info on this can be found in documentation page here:

    Hope that was some help! :slight_smile:

    Take care,

    I've compressed all the images listed and I've used Hummingbird to compress and move the css and js.

    The results I'm getting have improved but I'm still in the red on mobile which my client will not be happy about.

    What else should I be doing please?

    Hello there Jem Rose,

    I've just re-tested this domain using Google PageSpeed Insights and I'm still getting the same scores:

    I can still see in the report the exact same issues as shown in my previous reply though, about
    1. Optimize images and
    2. Eliminate render-blocking JavaScript and CSS in above-the-fold content
    so please do follow up my exact instructions and let me know when you're done! :slight_smile:

    Before replying back here, also grant support access to your website via WPMUDEV Dashboard plugin as described here
    so we can also have a better look inside wp-admin area.

    Warm regards,

    Hi Dimitris,

    thanks for responding.

    With Google insights I've just noticed, if I type in the name as I get the poor results.

    If I type the domain just as (without the www) the results are great. The same as you're getting.

    I've got no idea why that would be. Any ideas?

    I'm showing my client the latter results obviously.

    Thanks again.

Thank NAME, for their help.

Let NAME know exactly why they deserved these points.

Gift a custom amount of points.
