When browsing the Gallery 2 installation on the A1 Imports Gallery I noticed that the default implementation was to use H2 as the headings! This is horrible, pointless, and not very well thought out. I realize that its not the job of the Gallery 2 engineers but they went far enough to make it an H2 so why not just make it an H1? Anyway the problem has been solved and we’ll see what type of results we get. Be sure to use them on your site, but use them wisely. A good rule of thumb is to only have one per page that is very specific to the content. Over-bloating your page with these tags will definitely send the wrong message to Googlebot.
