Today’s post is all about image optimisation for SEO in 2020. We’ll be looking at several different elements including alt text for images, best practices about writing SEO friendly image names and the best tools to minimise your images without losing quality. But first, let’s answer the question:
What is image optimisation?
Image optimisation for SEO is reducing the size of your images so they load as fast as possible, without impacting the quality of the images. The second part of image optimisation is using keywords and phrases so they can be found in Google image search.
Why is image optimisation necessary?
There are two main reasons why image optimisation is necessary:
- Page speed
As we start to spend more time searching on our mobiles, the need for page speed continues to grow. There’s nothing more frustrating than a slow-loading website and compressing your images is usually plays a big factor.
- User experience
While Google is getting better at understanding images, it cannot fully read the image without any assistance. Using simple and plain language to describe your images will not only help them rank better in image search but also help with user experience.
Visually impaired visitors use screen readers that use image alt text to provide a better user experience.
