Are Your Images Optimised?

The speed of your site is vitally important when it comes to achieving sales. Research has shown that for every 1 second it takes your site to load, your business loses 7% of its revenue. For a large ecommerce site like Amazon, it could cost the business $1.6 billion in sales. One of the biggest culprits of slow sites is not having your images optimised.

The difference between an image that has been optimised and one that has not can be highly significant. For instance, take a look at the image below.

If I loaded this image to my site in 1920 x 1325 format, it would use up 503Kb. If I reduce the size down to 320 by 221 pixels, I use up significantly less memory (10.2 kb). That is a 98% saving on memory and yet, most images on the site don’t need to be any bigger than 320 wide.

This plays a more significant part when you consider the size of the file compared to the rest of a page. If we had this picture as part of the TwoFeetMarketing’s home page, then it would take up 44% of the entire homepage’s memory size. If I used the reduced size image, then it would be worth a mere 1.6%.

Therefore, the difference when you have images optimised and when you don’t could be as much as doubling the time it takes to load your website on a browser. This could in effect mean that your site’s images are forcing people to abandon your site before they’ve even landed on a single page.

Images Optimised For Search Engines

It isn’t just about optimising your images for download that you’ve got to consider, although that is pretty important. You’ve also got to consider how you can optimise your images for search engines. Not even Google has yet determined how to look at an image and visually tell you what it is about.

Therefore you need to use text to tell Google what the image is about. There are several tags on your site that can help with this. They are: title, caption, alternative and description. Each one of these will need to be completed, with the same keyword inserted to ensure that they are going to be found with Google and ranked accordingly.

For instance, if I wanted to use this image:

I would set the title of the image as images-optimised remembering to use the (-) sign not the (_) to denote a separation in the words. The caption would read “are your images optimised”, the alternate text would be “images optimised for search engines image” and the description would be “a computer screen to denote that images optimised are good for websites”.

All of these qualities would be picked up by Google but what the search engine would be most interested in would be the two words images optimised.

With a strong targeting of those keywords on the rest of the page, a few back links and social media presence, then the site should rank fairly high on search terms.


Optimising your images is an essential part of how fast your site loads on a visitor’s browser and whether they can find you on Google. Getting these two elements right is important and takes some hard work. Yet with the initial work done, you will have more traffic, less bounce and greater sales.
