Hi Google now uses alt tags in their description of sites. And we are supposed to use the alt tags for accessibility (mainly for sight-disabled or "images-turned-off" users) So if I have a header logo on every page which links to the home page I should have an alt tag which says "my site logo - link back to home page" or something like that. However that is useless for google which will include this text in the site description. How do we get around this - it seems to me that we have a choice - search rankings that make sense in google OR alt tags that make sense for sight-disabled or "images-turned-off" users. And these two aims seem mutually exclusive. Any ideas?
