Hello,
I read in SEO guides that for onpage SEO, the <h1> header is kinda important. But what if you site consists of nested tables, with logo stuff and such on top, is the effect the same when placing the header in a table like for example:
<table>
<tr><td>
<table>
<tr><td><h1>header goes here</h1></td></tr>
</table>
</td></tr>
</table>
And what about the color and size of the header when using CSS classes for headers, if you change these values is the header value worth less for the google spider?
