How I Optimized Mobile Performance for a Small Business Website: Key Takeaways

Learn how I improved mobile performance for a small family-owned construction company, boosting their site’s performance from 47 to 98.

Optimizing a small business website for mobile is no longer optional—it’s essential for good SEO and user experience. Recently, I had the opportunity to work on a website for a small, family-owned construction company. When I started, the site had a mobile performance score of just 47. After implementing a series of targeted optimizations, I raised that score to a highly competitive 98. In this post, I’ll share the takeaways and key strategies I used to achieve this dramatic improvement, and why mobile performance is crucial for SEO.

Why Mobile Performance is Critical for SEO

With Google’s mobile-first indexing, the mobile version of your website is what gets indexed and ranked. In fact, if your mobile performance is poor, you risk dropping in search rankings, which can significantly impact organic traffic. Studies show that slow-loading websites result in higher bounce rates, which also negatively affect SEO. Ensuring your website is mobile-friendly is no longer just about user experience—it's a major ranking factor that directly influences your visibility in search engine results.

The Key Metrics: LCP and TBT

Two key metrics play a critical role in mobile performance: Largest Contentful Paint (LCP) and Total Blocking Time (TBT). These metrics are part of Google's Core Web Vitals, which directly affect your site's SEO. Here’s a closer look at how I optimized both:

1. Optimizing Largest Contentful Paint (LCP)

LCP measures how long it takes for the largest visible content element on a page (like an image or large block of text) to load. A slow LCP leads to poor user experience, causing visitors to leave before the content even appears. In this project, I focused on:

  • Updating image formats to WebP: Images are often one of the largest resources on a page, and serving them in modern formats like WebP can drastically reduce file sizes without compromising quality. This improved load times significantly, reducing the LCP.
  • Optimizing image loading: I implemented lazy loading for images, so that non-critical images only load once the user scrolls down the page. This ensures that only the most important content loads first, which helps improve LCP.
  • Reducing image dimensions: Where possible, I resized images to the optimal dimensions for their display size, preventing large images from slowing down load times unnecessarily.

These strategies helped achieve a significant improvement in LCP, providing a faster, more engaging experience for mobile users.

2. Reducing Total Blocking Time (TBT)

TBT measures the total time between First Contentful Paint (FCP) and the time the browser is able to respond to user input. High TBT can make a website feel sluggish, leading to a poor user experience. For this project, I focused on:

  • Reducing JavaScript execution time: Non-essential JavaScript was deferred, and critical scripts were prioritized to allow for quicker interaction.
  • Minimizing blocking resources: I ensured that CSS and JavaScript resources did not block the rendering of critical content. By asynchronously loading resources that weren’t immediately needed, I minimized delays in page interactivity.
  • Optimizing third-party scripts: I reviewed third-party integrations (like social media buttons and analytics) and ensured they loaded asynchronously to reduce blocking time.

By streamlining the JavaScript and other resources, I was able to drastically reduce TBT, improving the site's responsiveness and mobile experience.

Additional Enhancements for SEO and User Experience

In addition to focusing on Core Web Vitals, I implemented a series of other optimizations that contributed to a better overall mobile experience:

  • Ensuring all links were functional: I ran a comprehensive audit of all internal and external links on the site to ensure they were functioning correctly. Broken links not only harm SEO but also frustrate users, increasing bounce rates.
  • Linking to social media: I made sure the website was properly linked to the company’s active social media profiles. This not only provides easy access for visitors but also enhances the company’s online presence, which is beneficial for SEO.
  • Adding alt tags to images: Every image on the website was given a descriptive alt tag. This improves accessibility, ensures search engines can crawl and index images, and contributes to overall SEO.
  • Incorporating relevant keywords: I performed keyword research to identify terms that potential customers were searching for. These were strategically incorporated into the content to improve search rankings while ensuring the language remained natural and user-friendly.
  • Ensuring a coherent link structure: I optimized the internal linking structure so that key pages were easily accessible from all areas of the site. This helps search engines crawl the site efficiently and ensures a better user experience by reducing the time needed to find important information.

These additional tweaks ensured that not only did the site load faster, but it was also more discoverable by search engines, easier to navigate, and more engaging for users.

Takeaways for Your Own Mobile Optimization

When it comes to improving mobile performance, the process involves both technical adjustments and strategic decisions. Here are some key takeaways that you can apply to your own website:

  • Update to WebP images: Use modern image formats like WebP to reduce file sizes without sacrificing quality, which can improve load times and LCP.
  • Focus on performance first: Prioritize the loading of critical content, defer non-essential scripts, and reduce blocking resources to improve both LCP and TBT.
  • Ensure mobile-friendly links: Make sure all internal links are functional, and consider adding social media links to enhance visibility and engagement.
  • Use descriptive alt tags and keywords: Enhance accessibility and SEO by providing descriptive alt tags for images and strategically incorporating keywords into your content.
  • Optimize internal linking: Ensure that your site’s pages are easily navigable by users and search engines by using a clear and effective internal linking strategy.

Mobile Optimization = SEO Success

In conclusion, optimizing for mobile isn’t just a technical task—it’s an essential part of your SEO strategy. By improving your mobile performance, you enhance user experience, reduce bounce rates, and improve your chances of ranking higher in search results. For this small business, the results were clear: a mobile performance score that went from 47 to 98, along with an improved SEO profile, all thanks to focusing on performance optimization and SEO best practices.
