and • 17 minutes READ

With the increasing reliance on websites for various purposes, the demand for reliable website monitoring services has also grown. These services not only help you track the uptime of your website but also provide valuable insights into its performance and potential issues. But with so many options available, it can be overwhelming to choose the best one for your specific needs.

To save you time and effort, we have compiled a list of the top 10 website monitoring services that you can trust to keep your website up and running smoothly. Whether you are a small business owner or a website administrator, these services offer a range of features and benefits that will give you peace of mind and ensure that your website is always accessible to your visitors. Let’s explore the best options available and find the perfect fit for your website monitoring needs.

Almost 40% of visitors bounce if your website takes more than 5 seconds to load, and every second of delay causes a nearly 10% drop in conversions. On top of that, 1 in 4 visitors will leave and never come back after one failed web transaction. If you think these stats do not involve you because your website is fast and reliable, consider studies done by Unbounce. The team has found out that only 15% of websites operate at an acceptable speed and standards established by Google. Therefore, chances are your website is one of those that drag behind and lose customers every day.

The target market expects from your website fast connection, instant response, and smooth, flawless interaction. In today’s world, speed is everything, and delays and failures are unacceptable.

However, the sad truth is, your website experiences regular outages and components failures, and you might not even know about them. You will be surprised to know that your website’s availability is far from being perfect (100%), which means that not only do you lose money and scare visitors away by being inaccessible, but you also miss opportunities to generate extra revenue during high-peak hours that are infamous for downtime.

The best practice is to monitor website uptime to get valuable information about your website’s performance to introduce improvements and, most importantly, get a chance to fix delays in time, keeping your customers happy.

Let’s find out what site uptime is, why it is important and what tools you can use to monitor it.

What Is Website Uptime?

Website uptime (also known as website availability) is a period of time when the web platform is unhindered available for online visitors. During this period, users can access the site and use its utilities.

As a rule, site uptime is presented as a percentage – it is a ratio of the available time to the total time. While you may expect it to be 100%, this is impossible. The deal is, whatever powerful server can be, it still cannot guarantee 100% availability for its “households.”

Why Do Websites Experience Downtime?

There are many reasons for website downtime occurrence, both unexpected and planned, for instance:

  • It can be a technical failure.
  • It can be a system failure.
  • It can be code issues.
  • It can be an additional load and heavier traffic on the server, like during official holiday seasons, including the biggest shopping event, Black Friday, and Cyber Monday.
  • It can be a machine adjustment.
  • It can be regular maintenance.
  • It can be human errors.
  • It can be hacker attacks.
  • It can be natural disasters.
  • It can be unexpected events like an electrical blowout.

Therefore, every website experiences downtime. As a result, hosting providers consider 99.999% uptime( that translates into 5.26 minutes of downtime per year) as a goal that everyone should strain after. By the way, Google is one of those several companies that are managed to hit this deadline. As for everyone else, this is almost impossible; therefore, hosting providers try to ensure 99.99% uptime (though in reality, it can be much less), which means that your website will be unavailable for only 1 hour during a year.

It is also crucial to note that this ratio reflects only website availability ensured by the server machine. That means it only considers the time when the server returns status code 200 OK for the website, and it does not consider other factors such as the failure of functions and performance of the web platform itself. For instance, you may host images on other servers or use plugins and components hosted by other computers, thereby drastically increasing downtime that may ruin the user experience and leave a bad aftertaste.

Speaking of ruining user experience and long-lasting wrong impressions, extended downtime may cause lots of inconveniences for your users and cause problems for running your business smoothly by tarnishing your reputation and shattering your revenue. Let’s consider some strong reasons why it is important to monitor site uptime to deal with those unexpected downtimes on time.

Why Should You Monitor Website Uptime?

Do you know that it is customary to mention a percentage value of uptime in service level agreements? Due to this custom, AT&T had to refund more than 6,000 customer accounts in the late ’90s, costing the company millions of dollars. A decade later, Xbox Live experienced thirteen days outage that set the company back a staggering sum of millions of dollars. There are many other similar stories out there.

Downtime can be a costly thing, because like it or not but not only should you make amends for the service issues by, for example sending apologetic notes, but you should also compensate it with your money.

On top of that, uptime provided by the hosting service is a subjective term whose percentage value is often inaccurate. Consider these scenarios taken from real-life situations:

  • Limited availability, which implies that the server experiences heavy traffic and detours users to the apology page, is considered the uptime. Technically speaking website is available, even though it does not provide an expected level of user experience and does not meet the declared standards.
  • Poor performance, which implies low speed for a website, is also uptime because the page does not return errors and time out.
  • Missing functionality, which implies when one or several functions do not work on a website, is also considered uptime.
  • The scheduled outages, which imply the actual inaccessibility of a website due to planned maintenance of the server, are excluded from the total time, thereby messing up the data and final result.

However, is downtime so crucial for your business? Let’s consider the consequences that it may bring to your business.

How Does Downtime Impact Business?

You Lose Money

With downtime, however short, you will suffer some form of monetary loss.

When your website is not accessible, your sales and current transactions come to a halt, regardless of whether you have a digital shop or SaaS platform. If people cannot buy products, order services, or hit the checkout button, they will leave, and some of them will never come back.

You Lose Customers

No one likes websites with sluggish performance, missing functionality, or colossal loading time. Consider these stats:

  • More than 70% of customers said that page speed impacts their decision to buy from the company.
  • The more people have to wait for the page to load, the more of them will bounce.
  • Almost 90% of customers said they would not return to the website with a bad user experience.

To make matters worse, the market is oversaturated: there is always an alternative to your business. Your target audience does not need any solid reason for never coming back after downtime.

Therefore, first-time buyers will just leave and never come back, whereas loyal customers, who are the lifeblood of every business, will start to doubt their choices and eventually move on to your competitor because their loyalty takes a hit every time they experience downtime.

Ruin Your Reputation

Downtime hurts credibility and trustworthiness that are the main pillars of reputation.

Today’s market expects from brands a certain level of quality. If you cannot meet these expectations, then you are out of the game.

The user experience has a significant impact on how people feel about your business. It affects all the campaigns and strategies both online and offline, thereby damaging the company’s perception across the board.

Lose Positions in Search Engines

Google punishes websites for low speed and poor performance. Although this does not trigger the Google penalty, this certainly downgrades your positions because downtime is crucial in ranking. That leads to less organic traffic and fewer conversions.

Should You Monitor Site Uptime?

You should monitor site uptime to avoid all those consequences that we have mentioned above. However, that’s not all; with constant tracking of site availability and fixing problems on time, you may keep customers happy and meet the target market’s expectations, thereby bringing to your business some considerable benefits. For instance:

  • Maintain trust and loyalty.
  • Increase trust and loyalty by providing customized status pages.
  • Avoid money loss.
  • Generate extra revenue.
  • Ensure excellent user experience.
  • Get higher ranks in search results, thereby increasing your online visibility.
  • Generate more traffic.
  • Get the most out of peak hours.
  • Enhance reputation.
  • Improve brand identity.
  • Keep visitors happy.
  • Win over new clients.
  • Detect hackers attack fast.
  • Protect your site from cyber threats.
  • Measure the reliability and stability of the system.
  • Get insights into your hosting provider’s performance.

In a word, monitoring the site’s uptime keeps your website up and running and preserves good relationships with the customers securing a fine reputation for the brand.

How Do You Monitor Website Uptime?

Since no one is safe from downtime, it is highly recommended that every business monitor the site. How to do this? Simple. Just check your website every single minute to see whether it works or not. Not only should it load fast, but also all the components should work as intended. You should be able to conduct a search, hit buttons, move through slides, use a shopping cart, etc. On top of that, you need to check the website from various locations.

If you have a huge company, you may create a department for that. This team should send requests to a resource to see if it responds and interact with the components to see whether they are fine.

However, if you run a small- or medium-sized business, a non-profit organization, or a personal blog, this approach is not feasible since you do not have so much time; and there is a big chance that you miss out on some crucial details.

More so, the manual approach considers to be hectic, tiring, time-consuming, and at some point irrational. Therefore, it is advisable to use site tracking services that do all the heavy lifting. They automatically ping resources, interact with components faking human behavior, check protocols, provide thorough reports, and send notifications to the owner.

Benefits of Automatic Uptime Monitoring

Uptime monitoring services are your online security guards that provide an extra layer of defense for your system by catching suspicious activity in your system and the unintended behavior of your website. They offer numerous benefits in the financial and efficiency aspects. Let’s consider some of their features to unveil their potential:

  • They have numerous monitors that give you a complete picture of website performance.
  • They give insights into how your website performs in different countries.
  • They monitor the speed of different pages to give you hints on what should be improved.
  • They send a quick notification when something is wrong with the website or any service or component.
  • They send website down alerts when the hardware fails.
  • They notify you when you need to get your site back on track.
  • They help to understand the server’s performance and effectiveness of your hosting provider.
  • They provide a detailed report covering such crucial factors as response time, browser and geography metrics.
  • They can reach you through various means of communication.
  • They can even alert your customers.

Although automatic uptime monitoring services may require you to invest some money, they have a positive ROI from short-term and long-term perspectives.
