I noticed that when all CSS is removed, my site doesn't display the Banner (obviously), so I put a text link back to the home with my keywords (which is also the site name) to display for search engines and for non-graphic readers.
Now that this link is there, the first link on every page of my site is my keyword and return link to the home page. It's not an H1, but it's bold.
Is this good for SEO or overdoing it? I'm not sure what the best practice is here, but I heard it was good to have your keyword first. I just don't want it to reduce the weight of other pages h1 tag or the more specific topic pages.
