Hi

Not sure if the software in this post is too 'artistic' but maybe something there will work.  From SEOgadget / Richard Baxter

Hi

Both sites are showing for me in Bing on site: search, searches for the domain and brand name searches.  What are the other searches/keywords where ranking has dropped?  At quick glance I didn't see anything out of the ordinary in Bing.

Bing could be doing something wonky... see where I show you on that search - http://screencast.com/t/2KGmi5gWO

I just did a post on my site this week about some weird Bing results, so I wouldn't be surprised if there is something weird happening.

The big question is, how is traffic? Did you check analytics? Its not impossible it could be a rank tracker error.

In general its bad practice to put images in the H1. This doesn't mean if you just stuff a few keywords in them that you'll rank better either. But the Header tags are meant to hold text - text that accurately describes to the reader what they should expect to see below the header.

Bill's article on headers is fantastic.

And the original source from w3.org says:

"A heading element briefly describes the topic of the section it introduces...." - basically that it's meant for text. Source

So as Bill says, if you correctly set up a semantic relationship between the title, headers and content on the page, you can help users and engines understand what the page is "about" and thus rank better in that sense.

Hope that helps!!
