Site Performance, Core Enhancements, SEO & Metadata, Performance, Site speed

JCH Optimize improves the performance of your website by performing several optimizations to the HTML page aimed at improving the Web Vitals measured by PageSpeed Insights, such as First Contentful Paint (FCP), Largest Contentful Paint (LCP), Speed Index (SI), Cumulative Layout Shift (CLS), Time to Interactive (TTI), and Total Blocking Time (TBT). These metrics attempt to quantify the quality of the user experience. JCH Optimize can improve these metrics to provide a better user experience and improve your PageSpeed scores.

Optimizations Performed By JCH Optimize

JCH Optimize optimizes your pages by automatically performing some recommended strategies offered by PageSpeed, which include:

  • Minify CSS and JavaScript files and the HTML. Unnecessary whitespaces and other characters are removed to reduce network payload sizes and script parse times.
  • Eliminate Render-Blocking Resources. Inline critical JavaScript and CSS and defer all non-critical resources to prevent resources from blocking the first paint of your page.
  • Defer offscreen images. Offscreen and hidden images are lazy-loaded after all critical resources have finished loading to lower Time To Interactive (TTI).
  • Add Width and Height attributes to images. Set an explicit width and height on image elements to reduce layout shifts and improve CLS.
  • Enable text compression. Boilerplate codes are placed in the .htaccess files at the site's directory root to instruct the server to serve text-based resources with compression (deflate or brotli) to minimize total network bytes.
  • Preload critical resources. Automatically analyzes each page to identify critical resources to load with a high priority by HTTP/2 enabled servers to improve LCP time.
  • Reduce initial server response. A Page Cache plugin is included in the package that integrates well with the JCH Optimize component and significantly reduces time-to-first-byte.

… and more.

Benefits of Using JCH Optimize

Research has confirmed that 40% of visitors will leave a website if it takes more than 4 seconds to download. Also, Google and other search engines have indicated that their ranking algorithm increasingly factors website download speed. The benefits of using JCH Optimize then include the following:

  • Improved user experience. Your users will have a pleasant experience as they browse your site.
  • Improved SEO. Your rankings in Google search pages can increase and improve organic visibility in internet searches.
  • Improved conversions. Your website revenue also increases with increased traffic volume and visitor retention.
Pro Version Available

A paid version is available on our website with more optimization options, advanced features, and premium support to resolve issues and assist with optimizing your site.

Ease of use
WARNING: when playing with the settings, especially JS settings, make sure you test features on your site like contact forms, etc after!

La mejor inversión

Posted on 05 December 2022
Gracias a versión premium, mi página web podrá volver a competir por los primeros puestos. ¡Google! ¡Hemos vuelto! Lástima no invertir antes
Ease of use
El plugin es bastante intuitivo y la versión de pago tiene algunas opciones extra que merecen la pena. Es cuestión de ir probando...
Se me atascaba un poco el CLS y tenía problemas con el menú de móvil, fueron muy atentos, me ayudaron a resolver estos problemas. Un 10!!
La verdad es que solo la miré por encima y algo puntual que me pasaron, por lo que vi parece estar bien.
I used this to: Siempre había usado JCH Optimize en la versión gratuita, pero al sufrir caídas en las SERPs de Google debido a la experiencia de usuario, me puse a trabajar. Uso Gantry, en el sitio que probé tengo joomla 3.10 y mi puntuación ahora, es de 100!!!!!

Still the best?

Overt the years I have tried all the solutions out there and in the Joomla extensions directory, but I always come back to JCH Optimize.
Ease of use
Mostly easy. But you may have to tweak your .htaccess file and play with settings to get a smooth workable result so persevere!
I presume support is okay, not really tried it, I like to solve all my own problems!
Only gripe, since eberything else was clear in the online manual, was lack of any detail on how to set up CDN for cookieless domains.
I used this to: All joomla websites I host (currently circa 20) and speeding them all up. Once configured it typically more than halves the page load times
Its sometimes hard to fit the optimal settings but with the help of the support I was able to make good speed improvements
Ease of use
It cannot be easier! You just have to push some buttons but you should understand what they are making.
Outstanding. Thanks Samuel for your patience and great work! He is explaining everything very well and tries to find the optimal settings.
Everything there whats needed - you can find a good documentation on the website
I used this to: Optimizing Page Speed for SEO and fit the Google Web Vitals and some other stuff

Pictures stops to show as a result of this plugin.
Can not uninstall (Error: Class 'JchOptimize\Core\Admin\Tasks' not found )
Ease of use
Too many buttons. Only five is not in evaluation. Everything is clear but not working properly.
too many things are described on the documentation page that characterize the strange behavior of plugin
I used this to: Optimising site to make it work faster. No results. Pictures stops loading. Site loading became unevenly.

Not useful anymore!

Bad experience after updated to latest version. Exception files disappeared and there is no control on anything!
Ease of use
New version has fewer items to configure and can be consider as a simple usage
I don't use it ever and can not judge that really but seems that reasonable
Site is useful for checking changelog and difference between predefined compression modes
I used this to: some commercial sites but for now should install older version unfortunately
This really does what it says. The scores on Google's speed checker for our webpages went from the 20s and 30s up to the 70s,80s, and higher
Ease of use
The complexity of the various options does not make it particularly easy to use, but it can be figured out, especially with some support.
Support was easy to access and helped me sort some issues. Thanks for the help :)
Good documentation, except for one funny bug where the text does not display well on Firefox. So I used the Edge browser instead to read it.
I used this to: Increasing speed on two sites we own. Again this was shown to be true on Google's speed checking page. Some of our pages are now getting scores of 100 on there, when they were much lower before installing this plugin.
Does its job and definitely made my website much faster! Especially when using the "Optimum" setting and the Pro version.
Ease of use
Pretty easy to use. Can cause some minor CSS bugs, but with some small adjustments these are solved thanks to the great support
Excellent. I got help with all my questions and some good advice
Nothing to complain about. I found what I was looking for in the documentation
I used this to: Classified ads website that was really slow before installation of JCH

Great Extension

Posted on 09 May 2021
Excellent extension for speeding up ones website's images and other issues I had quite a large problem with my websites running very slowly
Ease of use
Took a bit to get used to but it works very well and does the job so quickly and efficiently probably the best Joomla extension I have ever u
Excellent support the author JCH Optimize Pro when I contacted him optimized my website for me and there was a lot to sort out you thank you
no problems with documentation and its quite easy to follow and use and a lot cheaper than getting a professional Joomla expert to sort thin
I used this to: I use this editing and speeding up my website and my other websites the image optimizer is something very special and is a must to have when editing a Joomla website the author must have spent a lot of time and effort developing JCH Optimize Prof
I use this plugin on all my client's site, the auto-optimizing of images, conversion to webp format, and lazy load options are awesome.
Ease of use
Easy to implement, worthwhile to read the documentation and understand what the settings are to acheive the best results.
Fantastic support. Fast responses, great explanations. Highly rate their support service. A++
Good documentation which explains the settings. Have referred to it a few times, although it is mostly intuitive.
I used this to: I use the Pro version on 60+ Joomla sites that I manage, to achieve much better Google Web Core Vital performance scores. I wouldn't use any other component. Pro version gives you the extra functionality needed to get even better performance scores.
