The Importance of Website Loading Time

Have you ever attempted to open a site and it took a long time to load? I bet you weren’t pleased with the experience. A slow-loading website can be frustrating to work with. In fact, based on data from March 2016, Google revealed that as much as 53 percent of users are likely to abandon a mobile site if it takes less than three seconds to load. According to the Google Webmasters Blog, the acceptable loading time for an e-commerce site is two seconds. Therefore, if your site takes several seconds to load, you may be losing customers.

In the quest to create the most stylish site, sometimes we sacrifice on performance. But this is a wrong approach and affects your business in different ways. Did you know that Google factors in site speed into search engine ranking? Yes, the American multinational added site speed into its metrics for search engine ranking in 2010. So, those few seconds that it takes your site to load could actually be the reason why your business is slacking.

Due to the millions of sites in the virtual world, people can be finicky. It doesn’t take much to push users away from your website today. Slow loading time is one of the reasons why people shun a site. There have been many studies to show the adverse effects that a slow site can have on traffic and user experience. Apart from slipping below on search engine rankings, let us look at some effects of a slow-loading website on businesses.

The Effects of a Slow Site on Your Business

Poor User Experience

User experience is everything in the world of business. It can make or break your company. It is easy to assume that user experience only relates to the product or service you provide. Today, user experience also extends to your website and even response time on social media platforms. First impressions matter, and even more in the world of online business. Your website is usually the first point of call for people who are considering whether to patronize a company’s product or service. If you fail at providing an excellent user experience on your website, that same negative image will be extended to the products and services that your company offers.

A fast, highly responsive and easy-to-use site is an essential aspect of user experience. It adds to the overall positive image of your company. In the same way, a slow site puts users off and may prevent them from even engaging with your company to try your products and services. In fact, statistics show that one out of every four people will cancel a page if a site takes longer than four seconds to load. A fast-loading site presents an image of a professional company.

Low Conversion Rate

As indicated above, a slow-loading website can affect your conversion rate – this is especially true for e-commerce stores. No one wants to deal with a site that takes forever to load. Nearly 50 percent of Americans will give up trying to access an online store if it takes longer than three seconds to load. According to Amazon, a one second lag in the loading of its store costs the company up to $1.6 billion in sales annually. One second seems like nothing, but the effect compounds over time. Walmart was able to increase its conversion rate by two percent by increasing its loading time by just one percent.

In Akamai Technologies’ State of Online Retail Performance report in 2017, it was revealed that a 100-millisecond delay in the loading time of an e-commerce store could reduce conversion rate by up to seven percent. It is clear that a fast website is critical for success.

Negative Image

One of the most damaging aspects of having a slow-loading website is the long-term effect that it has on your company’s image. As indicated above, users are unlikely to take the time to engage with your site if it is taking a long time to load. What’s worse, this image lingers. Therefore, even if you realize the importance of rectifying the slow-loading time of your site and fix it, you would have an uphill task attracting visitors.

According to data from Akamai and Dynatrace, up to 79 percent of shoppers are unlikely to return to a site if they encounter issues like slow loading time. As many as 44 percent of shoppers will tell their friends and acquaintances about a website the bad experience they have with a site – even more disturbing they may do it on social media and reach millions of people. Also, up to 57 percent of people will not recommend a business with a website that loads slowly. But that’s not all. Your website is likely to rank low on search engine results and bloggers are unlikely to link to your content. Ultimately, this contributes to building a negative image of your business, nullifies your best marketing efforts, and keeping potential customers away.

Why is Your Website Loading Slowly?

There are many reasons why your website may be loading slowly. It may have to do with your server, the size and format of files on your site, the high volume of traffic you’re receiving, an old content management system or even too many file requests. Thankfully, there are ways to fix all of these issues. If you are not conversant with these things, consult a professional webmaster for assistance.


The advancements in mobile technology today means that smartphones are becoming faster. Therefore, you need a faster website to match that. The fact that your site was fast five years ago does not mean it is still fast today. You must make it a continuous effort to ensure the loading time of your website is on par with that of the top sites of the era. There are many tools to check the speed of your site including Google’s PageSpeed Insights, YSlow or WebPagetest.

On the other hand, eCPM is calculated by advertisers after an ad campaign is finished and regardless of what buying model was used – CPM, CPC, CPA. Because of some over or under delivery by the ad network or the publisher, an eCPM price may vary from a CPM rate.

Best Practices for Mobile App User Engagement and Retention

Quick Links:

The mobile app industry is highly competitive. There are billions of mobile app users across the world, and thousands of mobile apps are released yearly. Although the potential for growth is high, mobile app creators need to do a lot more to succeed.

User engagement and user retention are crucial to success in the market today. A mobile app with low user engagement and retention is bound to fail. Active users are at the core of profitability with mobile apps. If you have a mobile app, there are some strategies that you can employ to boost your user engagement and retention.

Smooth Onboarding

First off, you must make your app unique and attractive enough to make users check it out. In other words, it must play a useful role in their everyday lives. If you can achieve that, the next step is to ensure that users do not struggle to get a grip on how your app functions. The goal of your app design must be to make users operate it intuitively.

Developer in officeFailure to achieve this can result in user discontent and app abandonment. Usability must be at the core of your user engagement and retention scheme. A lot of thought and analysis must go into the design of your app. If the onboarding process is complicated, users are likely to uninstall your app or stop using it.

One way to make the onboarding process of your app simple is to avoid asking for too much information before giving users access. The goal should be to remove all the unnecessary roadblocks and allow users to get a taste of what your app offers. Some of the biggest apps today like Facebook use this strategy. Research shows that users tend to recommend apps they find useful to their family and friends.

Key Takeaway: The onboarding process of an app should be fun and straightforward.

Communication is Key

Communication is essential in strengthening the user engagement and retention of your app. Not just communicating with your users, but listening to their opinions. As a developer, you must take the views of users into account. Knowing what your users think about your app puts you in a better position to make the right improvements.`

Besides feedback, user data analysis is another way to gather valuable information about which features of your app are engaging to users. It will show also reveal the aspects of your app users do not like. Data analysis can go a long way to help you improve user engagement and retention on your mobile app.

There are many ways developers can get feedback from users. You can create a section on your app where users can drop their suggestions. Another way to find out what users think about your app is to read reviews. There are many platforms online where users write about their experiences with apps. For example, you will find lots of user reviews on App stores. The comment section of tech blogs can also provide some information about the experiences of users. Social media is another gold mine for unfiltered comments about your app. Surveys are another viable option to gather feedback. Polls are more specific and deliberate; you can ask what users think about particular aspects of your app. You can contract professionals like Buildinary to analyze your app and provide an expert opinion on how you can improve it.

Key Takeaway: Listen to your users.

Show Users you Care

care for usersTo engender loyalty among your users, it is essential to build a sense of community. You must let users know that their suggestions are valued. As much as possible, respond to user’s comments. Responding to feedback from users is one thing, but you must also attempt to implement their recommendations where possible. Users feel more valued when they see that companies take their opinions seriously.

Key Takeaway: Work to build a relationship with your users.

Make It Personal

Anyone abreast with the tech market knows that personalization is one of the secrets to keeping users. It can go a long way to enhance user experience, particularly with mobile applications. The more personalization options that a mobile app offers, the more it is likely to engage users. You can harness data to personalize content for your users. Users are likely to find relevant content more appealing and would spend more time on your app. Some simple personalization options like making the name of each user appear on the screen or allowing users to choose a different interface can go a long way to make people fall in love with your app.

Key Takeaway: Give users options to personalize their experience on your app.

There are many other equally good ways to improve the user engagement and retention rate of your app such as offering discounts and adding social media features to your app.
