When you have an online store, one of the many aspects you need to master is image optimization. Now, if you think this is just to reduce the loading time of your website and its pages, there is something more you need to know about – it also attracts more potential shoppers to your website, those going through Google images looking for what they need.

Image optimization?

The term basically refers to reducing the file size of the images you use on your website, taking it down as much as possible, without compromising on their quality.

In addition to the reasons mentioned above, image optimization also helps with SEO, helping attain better ranking for your images on search engines.

Before we move on to listing down some of the best tools to reduce file sizes of your images, here are some tips for uploading the same:

Images to Use

If you wish to add quality images on your website, there are images you should and shouldn’t use. Following are images you can use:

Permitted photography images – These will be images captured by a photographer, which you can use after getting the photographer’s permission to upload the same on your website. Don’t forget to include credits to the photographer.

Stock photos from websites like shutterstock.com, istock.com, etc. – When you get realistic photos from such sites, it is wise to use them as required. However, be sure to read the fine print just to check if you can use them on your website.

Images you captured – These are pictures you captured on your phone or camera and are actually the safest bet when it comes to uploading them to your website. If you are planning on going with this method all the time, you should think about investing in a good quality smartphone or camera.

Images to Not Use

Watermarked images – Keep in mind to never use watermarked images on your website. Some people tend to use image editing tools to remove watermarks from images in order to use them, but this is never a good practice, because there are various other ways to know the original source of an image.

Google and social media images – Most of the images you find on Google and on social media platforms are recycled again and again, getting to the point where their original source goes unknown. These images should not be used on your website unless you know the right source and acknowledge the same.
