If you are building or maintaining your own website then you may already be familiar with Yoast Search Engine Optimisation plug-ins and their informative blogs. This week I found their article on image optimisation very useful. If you haven’t got time to read the complete article then the 6 key points I took away were:
1. Check your website’s loading speed at Google’s PageSpeen Insights to see whether they flag your image sizes as a significant issue.
2. Compress your images to reduce their file size. If you haven’t got Photoshop the you can find free software online. I found a recommendation for jpegmini; however, if you have a lot of photos on your website you may have to pay to upgrade the software.
3. Include your page’s keyword in the file name.
4. Your images should adjust to the various screen widths. Thankfully, WordPress does this automatically as long as you using at least Version 4.4.
5. Captions are important. Yoast reference research that state captions are read 300% more than body copy!
6. Alt text – although a nice to have and doesn’t impact image SEO it does ensure full functionality of your site when your image can’t be displayed or your visitor is visually impaired.
