Is your White Hat Fading in the Wash?

[teacake23]

Is the following use of CSS to apply an H1 to our company logo a little bit black-hat? A SE bot should see the text without any problem but is it a legitimate use of an H1?

<h1 class="logoImage">My Company Name/Keywords Here</h1>

'logoImage' style would then be styled using:

H1.logoImage {
background:url(/images/logo.gif) no-repeat top left;
text-indent: -8000px;
}

These seems legitimate, although the H1 text is actually positioned off the visible page, I would welcome comments from anyone with experience of this approach.

The approach of placing content off the screen was discussed at SES London and I believe the bots will only include content within a certain range of pixels off the page. Does anyone have a magic number of pixels to use safely?

I have no experience of this but it probably won't pass a hand inspection by Google. If the H1 text was visible it wouldn't be an issue.
