Definition of website speed
Website speed, also known as website performance, refers to the amount of time it takes for a browser to load fully functional webpages from a given site. Web performance involves measuring and optimizing the actual and perceived speeds of an application, and monitoring the performance to ensure that the optimizations remain effective. Performance measurements involve various metrics and tools to assess the success or failure of optimization efforts.
One of the tools used to measure website speed and performance is Google's PageSpeed Insights (PSI). PSI reports on the user experience of a page on both mobile and desktop devices, providing suggestions on how the page may be improved.
Page speed can be described in terms of "page load time," which is the time it takes to fully display the content on a specific page, or "time to first byte," which is how long it takes for the browser to receive the first byte of information from the webserver. Site speed is the cumulative performance of the entire website, considering traffic distribution and performance.
Importance of (slow) website speed for user experience, SEO, and conversion rates
Website speed is crucial for user experience, SEO, and conversion rates because it directly affects these aspects and has a significant impact on a website's overall success. Multiple studies have demonstrated that site speed influences the conversion rate, with users staying on fast-loading sites longer and converting at higher rates compared to slower sites. Website speed is one of the most essential aspects of web performance, affecting search rankings and conversion rates.
Walmart conducted a study that showed a sharp decline in conversion rates as page load time increased from one to four seconds, with the grid suggesting conversion rates fell by about 90%. More general figures from Google indicate that the likelihood of a visitor bouncing increases significantly with slower page load times.
Website conversion rates drop by an average of 4.42% with each additional second of load time (between seconds 0-5). In an A/B test conducted among e-commerce customers, an increase of merely 100ms in site speed led to a 5% decrease in sales. Pages that load within two seconds have an average bounce rate of 9%, while pages that load in five seconds see their bounce rates skyrocket to 38%.
Google Core Web Vitals Explained
Google's Core Web Vitals Algorithm update was designed to optimize the search experience by measuring page load time, interactivity, and visual stability as pages load. Fast-loading pages provide a better user experience, and Google recognizes the importance of page load time for the overall user experience.
Core Web Vitals are a set of performance metrics introduced by Google to measure the user experience on a website. These metrics focus on three key aspects of the user experience: page loading, responsiveness, and visual stability. By understanding and optimizing Core Web Vitals, web developers can improve the overall performance of their websites and potentially achieve better search rankings.
The three main components of Core Web Vitals are Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS).
LCP measures the time it takes for the largest content element on a page to be rendered, providing an indication of how quickly users can access meaningful content. A fast LCP is crucial for a good user experience, as it ensures that users do not have to wait too long for the page to load.
FID, on the other hand, measures the time between a user's first interaction with the page and the page's response to that interaction. This metric gauges the responsiveness of a website, with lower FID values signifying a more responsive site. A good FID score helps ensure that users can quickly interact with a page without experiencing delays or frustration.
Lastly, CLS measures the unexpected shifts in the layout of a page while it is loading. A low CLS score indicates that the page has good visual stability, preventing users from accidentally clicking on the wrong elements or having difficulty consuming content. By optimizing CLS, web developers can provide a more seamless and enjoyable browsing experience for users.
Core Web Vitals are a critical component of web performance and user experience. By focusing on LCP, FID, and CLS, web developers can optimize their websites to provide a better experience for their users. Since Google uses these metrics as a ranking factor, improving Core Web Vitals can also lead to improved search visibility and increased organic traffic.
Site Speed and SEO
Site speed has a significant impact on search engine rankings, as it directly influences user experience and business goals. Fast loading pages make it easier for visitors to navigate a website and find what they are looking for, which in turn improves conversion rates and user retention. Furthermore, Google has been using site speed as a ranking factor since 2010, and in 2018, page speed was also included as a ranking factor for mobile pages and ads. Websites with poor performance and slow loading times can drive users away, while sites that load quickly will typically receive more traffic and have better conversion rates.
Content delivery networks (CDNs) can play a crucial role in improving site speed and, consequently, SEO. CDNs are networks of servers distributed across multiple geographical locations that work together to provide fast delivery of internet content, such as images, videos, and other assets. By using a CDN, website owners can reduce latency, load times, and server load, resulting in faster loading of pages and a better user experience. Improved site speed can positively impact search engine rankings, as it directly correlates with user experience and satisfaction, which are factors considered by search engines like Google when ranking websites.
In summary, site speed is an essential factor in SEO, as it impacts search engine rankings, user experience, and conversion rates. Implementing CDNs can help improve site speed, which in turn can lead to better search engine rankings and overall website performance.
Sitespeed and PPC
Sitespeed and PPC are essential factors in the performance of online marketing campaigns. Sitespeed refers to the time it takes for a website's content to load and display on a user's device, while PPC (Pay-Per-Click) is an online advertising model where advertisers pay a fee each time their ads are clicked.
A slow site speed can negatively impact PPC performance. This is because Google's ranking algorithm takes into account the loading times of landing pages and web pages, potentially affecting the visibility of your ads. Faster-loading sites are more likely to rank higher in search results, leading to increased sitelinks impressions and overall better PPC performance.
To improve both SEO and PPC performance, it is important to share keyword intelligence and align the strategies for both organic and paid traffic. Implementing technical SEO optimizations can significantly support a PPC campaign, as they can improve site speed and user experience.
Running a site speed test can help identify areas for improvement in your website's performance. Tools like https://gtmetrix.com/ provide quick performance analysis. Aiming for a higher site speed score on both mobile and desktop devices can lead to better PPC performance and a more successful online marketing campaign.
Ways to Improve Site Speed for Better Conversion Rates
Improve your LCP
LCP stands for Largest Contentful Paint, which is a metric that measures the loading performance of a web page. It is the time it takes for the largest image or block of text to be displayed on the user's screen after clicking on a link or entering a URL.
Now, let's talk about how to improve LCP. There are several steps you can take to optimize LCP and improve the loading speed of your web page. First, you need to identify the timing of your LCP. You can use lab data to drill down and optimize them.
It's essential to understand that improving LCP isn't just about fixing one part of your website; instead, you need to optimize every step along the way.
One of the first steps to improving LCP is to reduce your Time to First Byte (TTFB) timing. You can achieve this by using page caching, good DNS hosting, and a CDN.
Using a CDN (Content Delivery Network) is another effective method to improve LCP. A CDN can help reduce the distance between your website and the user by caching content on servers located closer to them, resulting in faster loading times.
Image optimization is also crucial for improving LCP. You can reduce page sizes by compressing and optimizing images, using next-gen image optimization, and ensuring the right image sizing.
There are several other effective methods to improve LCP, such as improving server response time, implementing caching, fixing lazy loading issues, minifying JS, CSS, and HTML files, and eliminating render-blocking JavaScript and CSS.
Tools like NitroPack and GTMetrix can also help you test your website and understand which user-profile has to have what type of LCP Experience on the web site.
Lastly, it's worth noting that if your LCP is longer than 4.0 seconds, it means that your Largest Contentful Paint is poor. To improve your LCP, you need to identify the issue and implement the appropriate solutions. By following the above methods, you can improve your LCP and provide a better user experience on your website.
Enhance FID
To enhance the First Input Delay (FID) on your website, you need to understand that FID is a Core Web Vitals metric that measures the time it takes for a browser to respond to a user's first interaction with a web page, such as clicking on a button or link. FID is an important aspect of user experience, and it can also impact your site's SEO rankings as part of Google's Core Web Vitals.
One of the most effective ways to enhance FID is to decrease or delay JavaScript (JS) execution on your web page. Since the browser might struggle to respond to user interactions while loading JavaScript, minimizing or postponing JS can significantly improve FID scores. If you have a Wordpress site you can utilize various plugins to optimize your FID score. Some useful plugins include WP Rocket, PerfMatters, Autoptimize, Hummingbird, and WP-Optimize.
How to improve a low CLS score?
Cumulative Layout Shift (CLS) is a Core Web Vitals metric that measures the instability of content on a webpage by summing shift scores across layout shifts that don't occur within 500ms of user input. A low CLS score is important for user experience (UX) and visual stability, as it helps ensure that the page is delightful and free from unexpected layout shifts.
One effective way to improve a low CLS score is by defining dimensions for images, videos, and iframes by including explicit width and height attributes. This ensures that your images are responsive and maintain a proper aspect ratio, which all leading browsers and screens can read.
To analyze and identify the shifting elements on a webpage, you can use browser tools such as "Inspect" and "Rendering" options in Chrome Developer Tools. This will help you visualize the layout shift regions and make the necessary adjustments to optimize your CLS score.
Another way to optimize your CLS score is by addressing issues related to media files and ads. Make sure to specify the height and width attributes for image files to prevent them from breaking your page's layout. If you are using embeds, predetermine the necessary dimensions and use a placeholder or fallback.
A good CLS score is lower, which indicates a more stable layout. The ideal score is less than 0.1, while scores between 0.1 and 0.25 need improvement, and anything above 0.25 is considered poor. By addressing unstable elements and optimizing media files and ads, you can improve your low CLS score and provide a better user experience on your webpage.
