Question: Also – can you hide keywords behind pictures?
Answer: In terms of straight HTML / on page SEO, absolutely. Every time you create an image you should name the image after a keyword, and use the ALT="" attribute to put text ‘behind’ the image so to speak.
In general, Google will perceive the text behind images in the ALT attribute tag to be the ‘kewyords’ of the image. So, yes, this is a good practice. I wouldn’t call this ‘hiding,’ however. Rather, you are just telling Google that such-and-such is a picture of such-and-such and always being aware of your target keywords.
