Is optimising your images important for your competitors?

When you upload an image, do you optimse it? Do your competitors? Do a search in Google Images to find those sites that are optimising their images. Do they match the organic SEO SERP listings? There are essentially three way to optmise your images. The first is to name the image with one of your keywords, e.g. dog-grooming-services.jpg.
Next, add appropiate alt test, i.e. img src=”dog-grooming-services.jpg” alt=”The Best Dog Grooming Service Baltimore”.
And the thrid way is to link your image to a relavant page, e.g. a href=”http://www.dog-grooming.com” img src=”dog-grooming-services.jpg” alt=”The Best Dog Grooming Service Baltimore”
