Large file sized images will cause your website to download slowly
If you are self-managing your website, are you optimising your images before uploading them to your website?
I have had a number of clients upload over 1MB images to their website which has a negative effect on their SEO as it really makes the website very slow to download.
There is a difference between images for print and images for the web. Images used for print purposes need to be of a higher resolution however images for the web need to be of a lower resolution.
Before uploading, always downsize the actual size of the image and then optimise it for the web which compresses and decreases the file size even further. If you upload a large image and then change the size on the actual page, this does not actually downsize the file size, it only shows the image in a smaller scale. The image will still take a long time to download as the actual file size has not changed.
Optimising your images for the web is very important. Large file sized images will slow down your page loading speed which will have a negative impact on your SEO. It will also have an impact on your users as they will not wait for a slow web page to load especially if viewing on a mobile phone.
There are a number of ways to optimise your images for the web. There are many free websites which offer image optimisation such as TinyPNG.com, Image Optimizer or Online Image Compressor. You may prefer using a software program such as Photoshop. There are also a number of WordPress plugins which will optimise your images. TinyPNG offers a WordPress plugin to compress both JPG and PNG images on your website. View at https://wordpress.org/plugins/tiny-compress-images/
To sum up, don’t make your website load slowly by uploading large sized image files. Always downsize and optimise your images for maximum download speed.
