WordPress is, hands down, the most popular content management system in the world. But like all giants, WordPress gets bigger and bigger every release; and it needs you to stay healthy and fast. Otherwise, your website can get slower and nobody likes slow websites. NOBODY. Not only your visitors hate your website, but also search engines (especially Google) penalizes you and drop your search engine rankings.
Improving your site’s speed will get you a better score on major speed testing services such as Google PageSpeed, GTmetrix, Pingdom, WebPageTest and will also improve your overall site’s usability. This will help Google and other search engines to rank your site higher in search results thus sending more traffic.
Speed Booster Pack is maintained & operated by Optimocha, a company that offers special speed optimization services filled with people who obsess about speed!
Benefits of Speed Booster Pack
Each second of delay can cause up to 20% loss in conversion rates (source: Google). “Conversion” means converting visitors to something more than a “visitor”: leads, customers, subscribers, followers… you name it.
You might lose more than half of your visitors if your website loads slower than three seconds! (source: Google again) More than half of your potential customers might get back to the search results page and navigate to your competitor. This is a huge problem, and it’s hugely overlooked among other SEO-related concerns. People don’t realize how important speed is, in the eyes of search engines.
That’s where Speed Booster Pack comes in: With its ever-evolving codebase, Speed Booster Pack aims to increase your site performance, page load times and PageSpeed (Lighthouse) scores! Optimocha, the company behind Speed Booster Pack, has a team with a pathological obsession for speed; so you can be sure that your site will be in good hands.
How to optimize PageSpeed scores with Speed Booster Pack
With our huge set of features, of course!
🌟 Core Web Vitals: Speed Booster Pack is made to improve your Largest Contentful Paint (LCP), Total Blocking Time (TBT) and Cumulative Layout Shift (CLS) metrics, which are also known together as Core Web Vitals. (Officially, TBT is not among of the Core Web Vitals metrics but First Input Delay (FID) is. However, Google recommends using TBT instead of FID.) With the right configuration, you can get your PageSpeed scores higher than ever!
🌟 Caching: Cache your pages into static HTML files, reduce database queries, get a faster website almost immediately. What’s not to love about caching?
⭐ Optimize Google Fonts: Did you know that there are better ways to load Google fonts? We like to brag about finding one of the best ways.
🌟 Lazy Load: It’s a disheartening issue that page speed tools encourage laziness… Just kidding, we love being lazy. And search engines will love your pages when you enable lazy loading for images, videos and iframes (except for the above-the-fold stuff, trust us).
🌟 Optimize CSS: Who needs all those different CSS files when you can inline them all into your page source? Especially when your CSS footprint is so small? Moreover, you can use the “Critical CSS” feature to essentially lazy-load all your CSS except for the CSS for above-the-fold.
🌟 Preload Assets: Have some fonts that load in all your pages, or a script, or some CSS files? Preloading them will help modern browsers serve your pages way faster!
🌟 WooCommerce Optimizations: Disable cart fragments, change Action Scheduler’s retention period, disable things like WooCommerce Marketing and WooCommerce Analytics… and more to come!
🌟 Dequeue Core Scripts/Styles: Dashicons, jQuery Migrate, emoji script, post embed script… If you don’t need them, you can now choose to prevent them from loading in the first place… which can get you to the first place on your Google SERPs.
⭐ Localize Google Analytics & Tag Manager: Tracker scripts aren’t the worst things that’ll slow your pages down, but they cause the most “recommendations”. Localizing Google Analytics and/or Google Tag Manager is a good idea to speed up your website then, right? Right?
⭐ Enable CDN: Integrate your content delivery network to your website by rewriting all static asset URLs with your CDN domain.
⭐ Cloudflare & Sucuri Integration: Connect to your Cloudflare or Sucuri account so you can clear your cache every time your page cache is cleared.
⭐ Declutter HEAD: Do you think all that useless junk in your should be gone? Us too! You know what they say: A clear works faster.
⭐ Other Features: Minify HTML, enable instant.page, trim query strings, disable self pingbacks, optimize the Heartbeat API, set a limit for post revisions, change autosave interval… Did we forget anything?
We’re constantly working on new features so stay tuned for more and more on every major release!
