Answering Your FAQs About Site Speed

The best interior design websites load quickly — making the entire process of going through portfolio images of past projects, inspiration pages, and blog posts much more enjoyable for the user. An image-heavy website can load quickly. It’s all about proper management and adherence to best practices. Consider Architectural Digest, Design Milk, Dwell, or Houzz. Each of these online interior design websites loads quickly despite its massive, ever-growing catalog of images and videos.
Whether professionals in the interior design industry or homeowners hoping to transform their spaces, visitors leave those sites feeling inspired and chock-full of great ideas. As an interior designer, that’s what your site should do for prospective clients, partners, and other visitors. In one word, visitors should feel inspired when they scroll through your site! They should NOT feel frustrated by slow load times!
But which websites take a long time to load and why? Let’s get into it!
Which Websites Take a Long Time to Load?

A variety of factors can contribute to a website taking a long time to load, regardless of its type. However, certain types of websites are more prone to slow loading times due to the nature of their content. Some examples include:
E-commerce Websites

Online stores with numerous product images, descriptions, and customer reviews may experience slower loading times. This is especially common when proper optimization techniques are not applied. If your design firm has an e-commerce element in addition to or instead of a storefront, customers might struggle against slow load times.
Image-Heavy Websites

This one is a given. Websites that primarily rely on high-resolution images or image galleries — such as photography portfolios, art galleries, architecture firms, interior design firms, and image-sharing platforms — can take longer to load.
Video Streaming Platforms
Websites that host and stream videos — i.e., video-sharing platforms or online video courses — can have slow loading times for users with slower internet connections. This is something to consider if you plan to embed videos on your site.
Social Media Platforms

As a designer, you have probably hemmed and hawed a few times about slow load times on TikTok, Facebook Reels, or Instagram. Social media websites that display a large number of posts, images, and videos from various users can experience slower loading times. During peak usage periods, slow load times are even more common.

Multifunctional Websites
Other online platforms also suffer from slow load times. Websites that offer multiple features and functionalities — such as online tools or web applications — can take longer to load due to the complexity of their operations.
Government or Institutional Websites
Whether the DMV or Department of Labor, we all know that government sites tend to be slow to load. Websites run by governments, institutions, or organizations that provide extensive information and resources may experience slow loading times.
Why Should an Interior Design Website Load Quickly?

As briefly alluded to above, there are many reasons why interior design firm owners absolutely must make site speed a priority. User experience, higher conversion rates, ranking on Google, and mobile friendliness are just a few of these reasons. Let’s delve a bit deeper.
User Experience
A fast-loading website ensures that your visitors enjoy navigating your site. Whether on mobile or desktop, each visitor expects your website to load quickly. If your site is slow, they are likely to become frustrated and leave. A smooth and fast user experience improves customer satisfaction and encourages visitors to stay longer on your website.
Higher Conversion Rates

Studies have shown that faster-loading websites tend to have higher conversion rates. These include Google’s 2018 study “The Need for Mobile Speed,” Akami’s 2017 study “The State of Online Retail Performance,” and Section.io’s 2021 “Website Performance Report” study. Deloitte’s comprehensive analysis found that “even a small improvement to mobile speed can have a positive effect on business results for brands.”
All of these studies reported that when your website loads quickly, visitors are more likely to complete purchases, sign up for services, or perform desired actions. This can produce more sales and leads for your firm.
Search Engine Ranking (SERP)

Search engines like Google weigh website speed as one of many different ranking factors. Faster-loading websites are more likely to rank higher in search engine results. This can lead to increased organic traffic and visibility.
Mobile Friendliness
With the rise of mobile browsing, having a fast-loading website is crucial. Users on mobile often have slower internet connections, and a quick-loading website ensures they can access your content without frustration.
Mobile friendliness is especially important if clients are coming to your website through a newsletter or from social media. To the former, some studies have shown that mobile opens can range from 50% to 70% or even higher. And to the latter, some reports indicate that around 80% to 90% of social media users access their accounts via mobile phones or tablets.
Competitive Advantage

In a competitive business landscape like that of the interior design industry, a fast-loading website can give you an edge over others operating in your shared market. If your website provides a better user experience than your competitors’ slow-loading sites, users are more likely to choose your firm.
Reduced Bounce Rate
A slow-loading website tends to have a higher bounce rate, meaning visitors leave the site quickly after arriving. Alternatively, a fast-loading site reduces bounce rates and keeps visitors engaged. This increases the chances of converting them into customers or clients.
Client Trust and Credibility

A slow website can give the impression of an unprofessional or poorly managed business. A fast website, on the other hand, instills trust and credibility, as it shows that you value your visitors’ time and invest in delivering a positive experience.
Better Accessibility

A fast-loading website ensures that users with slower internet connections or older devices can access your content without difficulty. This inclusivity can broaden your potential audience.
Cost Efficiency
A fast-loading website is more efficient in terms of server resources and bandwidth usage. This can lead to cost savings on hosting expenses and better scalability as your website’s traffic grows.
Why Do Websites with Lots of Images Load Slowly?

Image-heavy sites load slowly for a number of reasons — all of which can be mitigated. Websites with lots of images load slowly because of large file sizes, too many HTTP requests, limited bandwidth, poor server performance, significant distance between the user and server, and lack of image compression. Render-blocking and a lack of lazy loading can also inhibit site speed.
When images are placed in a way that blocks the rendering of other page elements, the loading process can be delayed. Without lazy loading, all images on the page will load at once, even if they are not initially visible to the user. This can cause unnecessary delays in loading visible content.

Why Do Some Websites Load Quickly on Desktop But Not on Mobile?
There are several reasons why your website might load quickly on desktop but slowly on mobile. Factors that might impact your site’s speed on mobile include unoptimized images, desktop-first design, browser incompatibility, and caching differences. It might also load slowly on mobile because of:
- Different internet connections between mobile and desktop.
- Files that prevent your site from rendering until the page has fully loaded.
- Too many HTTP requests.
- Servers that are optimized for desktop but not for mobile.
- The site has the right image format for desktop but not for mobile.
How Can I Make My Image-Heavy Interior Design Website Load Faster?

Now that you understand the importance of a fast-loading interior design website, let’s discuss exactly how to make that happen. Here’s what the experts recommend.
Optimize All Images
Compress and resize images to reduce their file size without sacrificing quality. Tools like Adobe Photoshop, TinyPNG, or ImageOptim can help you achieve this.
Select Image Formats Wisely

Choose the appropriate image format for each image. JPEG is best for photographs, while PNG or SVG is better for images with transparency and simple graphics.
Compress Images for Faster Mobile Loading
Use image compression techniques to reduce the file size of your images without compromising on quality. There are various online tools and software — such as TinyPNG, JPEG Optimizer, or ImageOptim — that can help you compress images effectively.
Implement Lazy Loading

Next, implement lazy loading for images on each web page. Lazy loading images means that images are loaded only when they come into the user’s viewport. This staggered image delivery reduces initial page load time.
Consider CDNs
Use Content Delivery Networks (CDNs) that specialize in serving images to aid image optimization and improve page load speed. CDNs store copies of your images on multiple servers worldwide, reducing server load and increasing loading speed. Utilize a Content Delivery Network to distribute images across multiple servers globally.
Minimize HTTP Requests
Reduce the number of images on a page to minimize the total HTTP requests. Combine smaller images into CSS sprites.
Use Responsive Images

Ensure different image sizes are selected for different devices using responsive images and the “srcset” attribute. This will improve each page load speed while maintaining image quality across mobile phones, tablets, laptops, and desktop computers.
Cache Images
Another step in optimizing images is setting appropriate cache headers. This allows browsers to cache images locally, which reduces subsequent loading times.
Minimize Image Carousels and Sliders
Another way to improve performance on mobile is to minimize use of carousels and sliders. Image carousels and sliders can slow down page loading on mobile devices. Consider using static images or implementing a single image that dynamically changes instead.
Enable GZIP Compression

Next, enable GZIP compression on your web server to compress all your website files before sending them to the user’s browser. Reducing image file size plays an enormous part in improving page load speed and image loading speed.
Work with an Expert to Optimize Code and CSS
Minimize and optimize your interior design sites’ code and CSS to reduce the overall page size and improve loading speed. Work with a front-end developer or web performance specialist to ensure this is done properly.
Retest Website Speed Regularly
Regularly test your website’s loading speed using tools like Google PageSpeed Insights, GTmetrix, or one of the other options outlined above to identify any performance issues and areas for improvement.
