When you think of search engine optimization (SEO), images may not be at the top of your mind – but they should be. Getting your images found with Google and other search engines gives your site a chance to rank as an image source rather than a purely written content source.
Try doing a Google image  search for “POU water filter.” The search returns thousands of images, each one giving you the opportunity for a click-to-conversion into your site.
Google needs you to tell them what your images represent, though, or there will be no way for them to tie your images to any industry searches or topics. How do you do this?
- 1. Make the file name descriptive. If the file name from your camera is DSC0987.jpg do not load that photo onto your website before changing the name. Google has no idea what DSC0987.jpg means. If you name the file appropriately, however, it will fundamentally help out. If the picture is of a residential ultraviolet purification system, rename it to something like residential-uv-purification-system.jpg before you upload it to your site.
- 2. Use ALT tags. Ensure that in your image tag you are using the ALT attribute, a la <img src=”images/residential-uv-purification-system.JPG” alt=”Residential UV Purification System” /> It’s important to note that ALT tags are used primarily for accessibility (for a blind individual accessing your site, for example), so keep them descriptive and don’t stuff them with keywords.
- 3. Try to use unique images. Don’t use the basic manufacturer-supplied image if at all possible. If you can, take your own unique product shots that will really set your images off from the competition.
