Image Name and Alt Attribute
Images are sometimes the forgotten child of SEO, but they too can bring valuable search traffic—even some traffic that regular text can’t reach. How many times have you searched for an image and ended up on the website that hosts the image? People often search for images alone, so it’s worth your time to optimize yours with keywords.
First, make sure the images are given logical, readable names—with keywords, if appropriate. For example, cupcake.jpg is better than img-00012.jpg. Next, don’t skimp on your alt tags; they are required for better usability in case your image can’t be seen, and they tell search engines what the image is. My advice is to write whatever you would want a user to know if the image didn’t load, ideally using some keywords.
Finally, ensure the image is in the right context—this is perhaps the most important feature that search engines look for. In short, place the keyword-optimized image close to keyword-optimized paragraph and header tags, and you’re on your way to turning up in an image search.
