What’s in it

Optimization of homepage + 5 pages , embedded images included
10Web Booster is made possible thanks to dozens of technical optimizations:

Page Cache

A cache is a fast-retrieval, short-term storage space where copies of recently accessed data and resources are saved. A cache significantly speeds up page speed and performance by downloading these commonly accessed data from the source, creating a copy of these resources and temporarily keeping them in a more easily accessible storage space from where the data can be accessed faster once the visitor returns. This short-term space can be a browser or a web server or even the original web server which also keeps different format copies of your resources. When you update your website data, the saved copies are also revised and updated.

10Web Booster uses a number of cache techniques, including page cache for HTML, file cache, smart cache invalidation, session-aware, and browser-aware caching and device and cookie-aware caching.

Page cache takes care of dynamic pages. In WordPress, dynamic pages are written in the PHP backend language, which require a great deal of time to generate, when compared to the generation time of traditional static web pages in plain HTML. Page cache creates and stores copies of dynamic pages in the format of static files, making their retrieval as quick as possible. When a visitor enters your site, this “static” copy of your page is immediately loaded from the cache instead of your hosting.

File cache, or resource cache, on the other hand, allows for storage of created minified and compressed scripts and styles. This process also speeds up your page speed and performance.

10Web Booster Pro employs backend or server caching, and through NGINX FastCGI Cache, caches a variety of resources from pages to feeds to 301-redirects on subdomains. This way you obtain page speed and retrieval at the fastest possible speed.

CSS & HTML Minification & Compression

The minification and merger of CSS and HTML is the procedure of reducing file size by a couple of bytes. The significance of this stems from the fact that larger files require more resources which may slow down website load time.

JS Minification and Compression

Compression of lengthy algorithmic JS codes is standard practice. The crunching of JS code, meaning, the removal of all the extra spaces, comments and other components which make the code readable and understandable, reduces the time of downloading JavaScript, directly improving WordPress Speed. By combining JS scripts, we can also minify the files, further reducing execution time.

Image Optimization

Image optimization leans on minimizing file size through image compression while simultaneously preserving image quality. 10Web’s image optimization achieves that and more. Through WebP compression, container-specific image resizing, and preloading of images, images can be optimized and loaded within seconds.

Container-specific image resizing finds or generates copies of images in various sizes. It then uses these differently sized copies of images on different-sized screens. This technique reduces valuable seconds of image load time and guarantees that you do not sacrifice quality for page speed.
Preloading images also significantly reduces page load time while providing your visitors with a seamless user experience. Preloading images means recovering images prior to visitor interaction. This method does make sense for certain cases – and not for all types of image, like mouseover images or slide show images.

Defer JS and CSS Execution

Having content that’s immediately visible when a user opens your website is only possible with file load optimization through prioritization of important CSS and deferral of JavaScript. That’s how 10Web booster ensures a 90+ page speed score as the best WordPress speed plugin.

Javascript files may cause a severe reduction in page load speed. This is particularly true of third-party JavaScript files that are poorly created. Third-party JavaScript files include
widgets, trackers, analytics, ads, social, chats, media buttons, pop-ups, and other files directly embedded on your site. These JavaScript files can reduce your page load speed, and therefore must first be located, and then divided into critical and non-critical JavaScript files. Those that are not critical must be delayed and only activated when a visitor interacts with the webpage.

Critical CSS

Downloading complete CSS files hinder the perceived speed of your WordPress website. After the user visits the webpages, the minimum-necessary stylesheets for the proper rendering of the webpage’s visible content are loaded, while the rest is served per need. Critical CSS doesn’t block page rendering and assists in passing the Core Web Vitals. 10Web Booster’s superiority in the case of critical CSS generation is due to its algorithms which programmatically parse through your web page and collect all the CSS rules used on that page. 10Web Booster guarantees that all stylesheets for critical CSS are present and unaffected. It also ensures that rule duplicates are deleted and that styles are structured to improve performance. 10Web Booster uses the critical CSS generation technique on five different screen sizes, from mobile to desktop to deliver the most effective page speed optimize in the market.

Image Lazy load

Images are one of the largest resources on a page dragging your page speed. Through the image lazy loading technique, you can delay the loading process of all the images on your page, except for those in the view of website visitors. This method saves significant seconds of load time and drastically improves all Core Web Vitals. 10Web Booster ensures that its lazy loading algorithms work perfectly and do not conflict with themes and plugins. 10Web Booster also lazy loads background images.

Font Swap

The reduction and optimization of how web fonts load could potentially help in passing the Core Web Vitals assessment, thus, benefit your ranking on Google.Custom fonts require additional resources to load and only then does your page displays your hand-picked font, and of course, this takes time and adds much-feared milliseconds to your page speed. 10Web Booster adds font-display: swap. This technique first displays a generic font, therefore loading your page immediately, then swaps the default font with your custom-picked font once your original font style is set up. This swap method reduces page load time, and makes sure that FOUT or Flash of Unstyled Text and FOIT or Flash of Invisible Text issues are avoided.

Conversion of Image Format to WebP

Images take up website resources and unfortunately cannot be avoided. There are ways to reduce their large size. Conversion to different formats is one solution. Conversion to JPEG or PNG was the traditional method. There is another, a newer player which produces better results. Google’s WebP compression can reduce file size, on average, 25-34% smaller than a comparable JPEG image and 26% smaller than a comparable PNG image. This significant reduction in size, substantially impacts and improves page speed.

iFrame and Video Lazy load

Iframes and videos are even larger in size than images, so imagine their impact on your page speed. Through lazy loading of iframes and videos, we make sure that content not yet in the direct view of your visitor does not conflict with your page speed. The loading of these items is delayed until your user scrolls down. As with image lazy loading, iframe and video lazy loading enhance all Core Web Vitals.

Container-specific Image Resizing

The container-specific image resizing method involves identifying images on your page and creating different-sized duplicates of these images. The differently sized images are then used for differently sized screens. Small-screen devices receive the small-sized images, loading them at the optimal speed possible. Medium-sized screens load medium-sized images, loading images at the fastest possible speed without sacrificing image quality. Large-sized screens, likewise, load large-sized images, ensuring the best quality and the best possible speed. Therefore, with the 10Web Booster, instead of forcing your website to load an enormous image when the user is only looking for a thumbnail, you’ll have a container-specific image at your disposal.

10Web Booster Pro

Full frontend optimization of the entire website and all images

Backend optimization

Speed Optimization Modes

When your automated homepage optimization kicks off, we test out each and every one of the 4 modes. Consequently, we compare the results, and, as presumed, the mode that achieved the highest score while simultaneously keeping your website from breaking, will be set as your default.

You can choose any of the following four levels and manage the levels for each page individually from the Custom rules tab in your 10Web dashboard to provide. We provide the best page speed optimizer to any WordPress website, based on need.

  • Standard Mode: – Uses different standard speed optimization techniques.
  • Balanced Mode: – All optimization techniques in Standard Mode + Critical CSS
  • Strong Mode: – All optimization techniques in Standard Mode + JS Delay.
  • Extreme Mode: – All optimization techniques in Balanced Mode + JS Delay.

4. How can I optimize other pages of my website or websites?

After you connect your website and start the optimization for your homepage, you will be redirected to your dashboard. In the General tab, you will see a URL slot to add and optimize more pages. Add up to 5 inner pages in the free version. They will be optimized using the default mode we’ve set for your homepage, however, you can always change the optimization mode for a specific page from the Custom rules tab (Pro version).

We’ll leave you to it.

5. How can I upgrade to the Pro version?

You can complete your website optimization by switching to 10Web Booster Pro from your personal dashboard.

6. What is the difference between the four modes of optimization?

The four modes for your WordPress speed optimization plugin are the following:

Standard mode, which in itself includes the following features.

  • CSS & HTML Minification & Compression
  • Page Cache
  • JS Minification and Compression
  • Image Optimization
  • Image Lazy load

Higher search engine rankings
Up to 7% boost in conversions
Up to 40% boost in visitor engagement
Up to 53% mobile traffic engagement boost

8. How does 10Web Booster affect bounce rate?

With a 90+ page speed, averaging up to a load time of 1.5 seconds, bounce rate worries are out of the question with 10Web Booster. We’re better than good, literally. Good being an average of 2 seconds for load time, which translates to an average of 4 seconds of loading to cause a bounce. There’s no need to worry about your WordPress page speed optimization with the best website speed optimizer, 10Web Booster.

9. How long does the optimization take?

As a plugin that aims to speed up WordPress sites, taking too long wasn’t an option.

WordPress speed optimization usually takes only minutes.

10. Can I simultaneously use multiple speed optimizers for my website?

WordPress’ functionality is in its prime when there’s only one speed optimizer fix for any website at a time.
So using another speed optimizer alongside 10Web Booster is not recommended by either us or WordPress.

An alternative WordPress speed optimizer could be any one of the following:

W3 Total Cache
WP Super Cache
WP Rocket
WP Rocket Footer JS
WP Fastest Cache
Asset CleanUp
Shortpixel AI
Rocket Lazy load
Flying Scripts
Async JavaScript
PageSpeed Ninja
Swift Performance Lite
Swift Performance
Fast Velocity Minify
LiteSpeed Cache
WP Performance Score Booster
SG Optimizer

11. What’s the difference between cache plugins and 10Web Booster?

To sum up caching plugins, they attempt to speed up your website by simply caching files, clearing site cache, compressing cached pages, and performing HTML minification. They don’t require third-party servers for operation and run inside WP servers.

10Web Booster is more than just a plugin, it’s a service that speeds up your website with a wider range of optimization techniques. These techniques can only be implemented using a specific service for website optimization (10Web Booster services), rather than running the solution inside of the WordPress hosting server.

12. Does 10Web Booster replace all image optimization, caching and other optimization plugins?

Yes. 10Web Booster is an all-in-one solution for optimizing websites. It implements dozens of speed optimization techniques from simple minification to JS delay and critical CSS generation for frontend optimization and super-fast hosting for backend optimization. There is no need to run another speed optimization plugin along with 10Web. The only major feature it does not have yet is CDN which is included in the roadmap.

13. What are the caching features of 10Web Booster ?

10Web uses page cache and file cache. They are used to store dynamic webpages as static files. When a repeating visitor accesses your webpage, a “static” version of your webpage is quickly loaded from the cache. This feature works for all websites optimized with 10Web Booster, including those not hosted on 10Web. For sites hosted on 10Web, even more caching options are available, including NGINX FastCGI Cache.

I have been using the 10Web plugin for around a year, and I am still using it for our company’s website, ingreland.com. It has done a great job optimizing our website and improving its loading speed. Now, our website loads in under 2 seconds. Apart from this, their customer support is excellent and has provided me with great assistance.
Julai 20, 2024
The score of our website has changed significantly. Thanks to 10 web booster speed optimizer plugin and quick customer support.
Julai 17, 2024
Plugin did wonders for me. Had to utilize customer support and they fixed m one issue. Took both my mobile score and desktop score to the 90’s consistently. Recommend this product.
Julai 8, 2024
I really needed to speed up my site and I made the mistake of trying this plugin for several weeks. All I managed to do was slow down my site and waste days trying to find solutions with very poor support. I can’t believe they have so many positive comments here and on Trustpilot, it could just be a fraud! The support is very bad, most of my messages have been closed without response! Some support don’t know anything about Wordpress, one of them didn’t know what Related Posts were! I made the big mistake of believing in it and trying the paid version, but don’t make that mistake because there are no refunds, even when, like me, you make a mistake when paying, I lost a lot of money. Don’t think that being on Cloudflare enterprise will speed up your site either, because you don’t have access to the settings! My Cloudflare pro is more powerful because I can adjust it myself, and there are many SEO-friendly options that you lose if you sign up with them! And you’re not protected from bad bots. I once had over 100,000 visitors, but the vast majority were bad bots. On my personal Cloudflare account I can block them, but on their Cloudflare Enterprise account, they don’t block them because they take money when you exceed 100 GB of bandwidth. I have costal VPS hosting which is perfectly sufficient for my site and its visitors, but when I was with them, my hosting alerted me every day that my site was slow and that I was consuming too many resources! As soon as I got out of this trap, my hosting returned to normal! I don’t know why my site was consuming so many resources when I was with them.
