In my many years in the internet marketing / SEO world, I have repeatedly been met with folks who do not see the value or importance of applying Search Engine Optimization best practices to any images on their web site or blog. I have prodded clients to rename images using keywords in the photo’s file name. There are so many key elements in a page’s content that can contribute to gaining visibility in search – why would you not leverage ALL of those elements.
Photo naming conventions can go add an additional element to your page – so why not take the time to rename your image files before uploading them to your website? In the case of eCommerce, your image file names can potentially impact your position in Google Shopping, if you have your products uploaded to their product database.
