Let's explore why: If we show cached pages to logged-in users, we can't display personalized content on the site. If we create separate caches for each user, the content becomes personalized, but if a website has 30 pages and 100 users, that results in 3,000 cached pages. This takes up a lot of storage space, and it also requires a lot of time and CPU power to pre-load the cache, often for users who may not even log in for months. Moreover, there are pages that we can't cache at all, such as the cart and checkout pages. Additionally, there are requests that can't be cached, like WooCommerce AJAX requests. Another significant issue is speeding up administrative operations on the admin interface. These pages can also be optimized with the help of a plugin organizer, but this requires manual setup and some expertise. How is Swift Performance AI Different? Swift Performance AI takes multiple approaches to solve these problems. As we've come to expect from Swift, these are typically unique, innovative solutions that no other optimization plugin offers. Fragments The Swift Performance AI Fragments feature allows personalized content to be loaded via AJAX requests. This way, logged-in users can be served from the cache, and the personalized parts also get loaded. Moreover, if you enable the Collage option, Swift automatically detects and loads certain content as fragments,... --- - Published: 2024-07-23 - Modified: 2024-07-23 - URL: https://swiftperformance.io/blog/why-should-you-use-a-premium-cache-plugin/ - Categories: general - Tags: coupon., css, image optimization, javascript Free cache plugins can provide a basic solution to speed up your website, but they have limitations, making them often not the ideal choice. Image Optimization Most free cache plugins don't offer image optimization because it requires too much computing power and can't be sustained without generating revenue. Since images are one of the biggest components of a website, not optimizing them can significantly slow down your site. CSS Optimization Proper CSS optimization requires even more expensive infrastructure than image optimization. Therefore, generating Critical CSS is not available or only limited in free plugins. JavaScript Optimization Many cache plugins simply delay JavaScript loading, which can be managed with free plugins. However, this method is outdated and delaying all JavaScripts can lead to problems. Additionally, modern and more effective optimization technologies are now available, such as those used by Swift Performance AI. Font Optimization Currently, real font optimization is only possible with Swift Performance, and it requires similar resources to image and CSS optimization, which can't be effectively implemented in a free plugin. Support and Development It's clear that both support and development are only sustainably financed if we're talking about paid plugins. While there are free projects developed by communities, usually neither the intensity of development nor the support compares to that offered by paid plugins. Switch to Swift Performance AI Now!

We are going to check what kind of errors can occur because of delaying scripts, and how Swift Performance AI can do it better. Runtime Errors When a webpage loads, certain events are triggered (like DOMContentLoaded, load, etc). Many JavaScript functions only run after these events are triggered because this ensures that elements (like buttons, images, etc. ) they work with are already present in the DOM. Most developers aren't prepared for their plugin or theme JavaScript files to be delayed in loading. Therefore, by the time the JavaScript loads, the DOMContentLoaded and load events may have already happened. In this case, some functions may never execute, which could result in missing or malfunctioning elements (like swipers, sliders, popups, menu, or other interactive elements). It's also possible that the execution order changes, which can lead to errors. Traditional cache plugins address this by allowing scripts to be manually excluded from the delay, which is time-consuming and difficult to test for every feature of the site to ensure it works correctly. Moreover, if one script is excluded, then every script that depends on it must also be excluded (like jQuery). Double Click Issues Since traditional cache plugins load scripts only upon user interaction (like click, mousemove, scroll, keypress, etc. ), a script might not execute on the initial click that triggers its loading. This is common on mobile devices where there's no mouse movement event, so nothing happens... --- - Published: 2024-07-05 - Modified: 2024-07-19 - URL: https://swiftperformance.io/blog/common-cache-issues-2/ - Categories: technical - Tags: field data, lab data, pagespeed, psi, seo Why Core Web Vitals Assessment Failed When PSI Performance is Good? In the second part of our blog series, we explore the issues that lead to the phenomenon where PageSpeed Insights (PSI) shows good performance in Lab data, but the Core Web Vitals Assessment fails. What is the Difference Between Field Data and Lab Data? Lab data for web vitals is collected in a controlled environment using emulated network and device conditions, while field data is collected from real users in real-world conditions. Lab data is useful for debugging and optimization, while field data provides insights into the user experience. Field data is a ranking factor for SEO, while lab data does not directly impact rankings or user experience. What Causes the Discrepancies? Let’s Look at it Step by Step! Network Speed Lab data tests run under controlled conditions, simulating a slow 4G connection (~1. 6Mbps) on mobile and a slower wired connection (~10Mbps) on desktop. In reality, better speeds are often available, but real-world conditions vary greatly. Extreme slow connections can occur (in underground garages, crowded places, large events, highways, trains, etc. ), significantly affecting average speed. It's also important, that during tests, only the webpage loads, while in real life, many other applications generate background data traffic (email clients, Facebook, TikTok, other social media preloads, location services, etc. ), slowing down the page load. Device Although Google intentionally uses lower mid-range devices for tests, the CPU time is entirely devoted to loading the page. On real devices, it's... --- - Published: 2024-06-27 - Modified: 2024-07-19 - URL: https://swiftperformance.io/blog/common-cache-plugin-issues/ - Categories: technical - Tags: ai, cache management, clear cache, common issues, nonce In this article series, we will review the most common cache plugin issues and how Swift Performance AI solves them easily and automatically. In the first part, we will examine the problems that can arise with cache management. Poor Cache Management One of the most frequent cache management issues occurs when a cache plugin fails to clear the cache when necessary. This often happens with various page builders because most cache plugins clear the cache when the save_post action is called. However, this doesn't always happen with some page builders. Another problem can arise when a plugin or theme is updated and the frontend changes, but the cache isn't cleared. Similar issues can occur with certain plugin operations, such as stock changes in a WooCommerce product, where clearing the cache is necessary. A common issue is when the homepage includes embedded posts (e. g. , recent posts or a product carousel). When a new post is published or a product is modified, the cache for the homepage (or other pages containing posts) isn't automatically cleared. However, it's also not ideal to clear the cache every time a plugin or theme is updated or stock changes occur, as this often results in unnecessary cache clearing. This not only wastes resources but also makes the site slower for visitors until the cache is regenerated. Another frequent issue is that many plugin and theme developers don't properly use WordPress nonces, causing them to expire regularly on cached pages. This can prevent forms from... --- - Published: 2024-06-07 - Modified: 2024-06-07 - URL: https://swiftperformance.io/blog/how-can-ai-improve-wordpress-speed/ - Categories: technical - Tags: ai, css, font, javascript, lcp When you think about AI and WordPress, content or image generation might come to mind first. However, Swift Performance AI is different from popular language models; it uses an expert system specifically designed to optimize WordPress speed. Let’s explore how it works. Image Optimization Swift AI not only optimizes images but also resizes them to ensure they are appropriately sized for all screen sizes. The AI image resizer uses intelligent rules to determine the best image sizes for each device, ensuring optimal loading times and performance across different screen resolutions. LCP Optimization Largest Contentful Paint (LCP) is a crucial Core Web Vital (CWV) score. Swift AI automatically detects if an image is used as the LCP element (even background images). When such an image is identified, Swift preloads it and excludes it from lazy loading, ensuring the page loads quickly and smoothly. Decreasing CLS Cumulative Layout Shift (CLS) can be a significant issue, causing unexpected movements of content on the page. Swift AI can detect elements that will be resized during the rendering process and intelligently set their size to minimize CLS. This proactive approach helps maintain a stable and visually consistent layout. Critical CSS Swift AI features a robust critical CSS engine that generates the smallest yet 100% failsafe critical CSS. Unlike other plugins that struggle with JavaScript-added classes, sliders, or animations, Swift AI predicts which CSS rules will be used during the initial page load and just after, ensuring that the critical CSS is effective and efficient. Real... --- - Published: 2024-01-31 - Modified: 2024-06-07 - URL: https://swiftperformance.io/blog/swift-performance-ai-intelligent-cache-management/ - Categories: technical In the dynamic world of WordPress, ensuring a swift and seamless user experience is crucial for website success. This is where Swift Performance AI's innovative cache management system comes into play, revolutionizing the way your site operates and interacts with its visitors. Intelligent Cache Management for Enhanced User Experience At the heart of Swift Performance AI lies an intelligent cache management system. This system is designed not just to cache your website content, but to do so in a way that is both smart and sensitive to your site's changing needs. For example, when you update a plugin, unlike traditional cache plugins that simply clear and regenerate the cache, Swift Performance AI adopts a more intelligent approach: it will invalidate the cache and analyze all pages to determine if cache regeneration is necessary. This means the cache is only regenerated if there are noticeable differences or updates that impact the page. This smart process reduces server load and ensures that visitors always have access to the most current version of your site, without unnecessary cache rebuilding. Strategic Page Prioritization for Enhanced Performance Swift Performance AI excels in its ability to identify and prioritize key pages for optimization. This is crucial for maintaining a fast, efficient site that caters to the most impactful visitor interactions. Here are some examples of how page prioritization works: Homepages and Landing Pages: Given their high traffic and importance in first impressions, these pages are optimized first. This is especially crucial for landing pages linked to... --- - Published: 2023-06-22 - Modified: 2023-06-22 - URL: https://swiftperformance.io/blog/boosting-wordpress-performance-with-code-optimizer/ - Categories: general, technical Swift Performance AI, the leading WordPress cache and optimization plugin, has unveiled an experimental feature in version 0. 5 called Code Optimizer. This cutting-edge addition tackles performance issues caused by poorly optimized themes and plugins. By automatically deactivating unnecessary plugins and implementing code improvements, Code Optimizer significantly enhances the speed and responsiveness of WP Admin, AJAX requests, and on uncached frontend pages (like Cart and Checkout pages) ensuring an exceptional user experience. The WordPress Performance Challenge WordPress themes and plugins often prioritize functionality over performance, leading to sluggish admin pages, uncached pages like the cart and checkout, and slow AJAX requests. Code Optimizer is designed to overcome these performance challenges. It intelligently deactivates unnecessary plugins for specific requests and applies code improvements to boost performance.

Due to the explosive growth of the online world, business competition is increasingly happening on the internet. People spend much more time online, so it is important for businesses to be present in the online space and reach their target audience effectively. Digital marketing allows us to reach our target audience effectively and increase the number of customers, and thus revenue. Digital marketing offers a variety of tools, such as search engine optimization (SEO), pay-per-click (PPC) advertising, social media marketing, and email marketing. The success of SEO and PPC marketing strategies relies heavily on website speed. Slow load times and overall performance can reduce website traffic and efficiency, which can also affect search engine rankings. Customers expect fast and efficient websites, and if they don't get it, they are likely to leave the website, resulting in business losses. Search engines attach great importance to website speed, and their algorithms take into account load times and performance when ranking websites. Faster websites rank higher in search engines, which can result in more visitors and higher conversion rates. Slow website speed presents challenges not only for organic search engine optimization (SEO), but also for paid search advertising (PPC). Low-quality ads and slow websites receive lower scores in Google's quality score system, which can reduce reach and increase costs for paid advertising. Slow website speed can also have a negative impact on customer satisfaction.
