6 Simple SEO Tips To Greatly Improve Image Rankings 


#1 Optimised File Names

Before uploading your image to your website, be sure to rename your image with descriptive content about the image and it's purpose (maybe include the focus keyword).  Most cameras will default to a naming scheme that’s not user-friendly (or search engine friendly).  As an example, using "jordan-air-1-mid-front.jpg is better than IMG00353.JPG."

#2 Optimised Alt Text

Once uploaded, you should make sure everywhere your image is added that its Alt Tag is a clear text description for the image that describes what it shows. The alt text could read: <img src=”chocolate-1.jpg” alt=”chocolate”/> However, a better alternative text that describes an image would read: <img src=”chocolate-1.jpg” alt=” dark chocolate coffee flavoured bar”/> Don’t try to take advantage of search engines with keyword stuffing though.

#3 Use Appropriate File Types

- JPG is the most common format for photographs. - PNG is best for line drawings, text, and when a transparent background is required. - GIF is best for moving images. Always use the extension offering the highest quality at optimal compression. Note: As of August 5th, 2020, you can use all the image formats Google Image supports, including BMP, GIF, JPEG, PNG, WebP, and SVG, in Structured Data.

#4 Optimised Image File Sizes

High-quality image with lossless compression - Site load time as an important factor in delivering relevant results to keyword searches. You should also try to resize the dimensions of your image in line with your site dimensions.

#5 Contextual Content

These days contextual relevance plays a big role. Surrounding text such as, on page copy, anchors (links), captions and heading tags ultimately tells search engines that your images are relevant to those terms mentioned.

#6 Use Original Images

Original images will beat out stock images any day of the week. Google values original content over reused stock images. Take your own photos where and when possible. Original photos can be traced back to only your website. 

Optional Tips

- For crawlability, create an image sitemap or make sure your images are featured in your sitemap. - Make your images mobile-friendly - the image should scale with the size of the site whether the user is using desktop or mobile. - Regardless of the image you choose to use, make sure there’s no copyright conflict. - Broken images make for poor user experience; you should prioritize fixing any images that don't display.
