Slow website loading? See what makes your website slow
Posted: Wed Jan 29, 2025 5:35 am
A number of issues can cause your website to slow down. Learn the main reasons why your website is slow and heavy.
With each new Google update, a new headache arises for those who have a website. And the search giant has been increasingly taking a toll on those who have a slow, heavy, poorly designed website, and so on.
With this in mind, I have gathered together in this post the main causes of slow websites.
I will also comment on what can be done to optimize your website. Sacrifices are not always necessary – sometimes you just have very large images or bad hosting, for example.
But as you will see below, in many cases some new zealand number dataset need to be replaced or redone – or removed altogether.

10 reasons why your website is heavy and slow to load
There are not just ten – some items on this list have more than one reason of the same type (i.e., problems that are related to each other).
But before you proceed, it’s important to make sure that your website is experiencing slow speeds. After all, it could just be a problem with your internet connection.

1. Heavy images
In practically all the slowness analysis requests I handle, the images are not optimized.
Keep in mind!
Did you know that choosing the wrong hosting can reduce your Google score, cause slowness and even leave your website vulnerable to hacks and viruses?

This is because many people upload images without processing them, such as reducing their width and height, compressing them or even using the correct extension.
Some cases border on the absurd: while consulting for a website, I found a background image weighing almost 2MB. To give you an idea, optimizing the image reduced the file to 366kb (that is, a reduction of 80%).
So, large, non-deferred images (see the second item on the list for more information) will not only slow down your site but can quickly consume your server resources (such as transfer limits).
