Confusion on schema.org

[oznappies]

I have begun marking up the site for schema.org and Google has now begun indexing those pages with a weird result. Instead of using meta description in search it is using the ALT text from an item marged as ImageProp="image". I was hoping it would display the picture not change my description.

Any ideas?

I will fix that, thanks, funny my seo did not pick up on that.

Well I can verify your results.

When I searched for "reusable nappies oznappies" at Google.com, your result page description appears normal. When I switched to the au site and searched for "resusable nappies" I noticed the alt tag.

I recall a video from Matt Cutts stating Google would use whatever information it determined best as the meta description. It seems odd to me they would select your image's alt tag. I have never seen nor heard of that before.

I will point out, your alt tag does appear odd to me. Normally I would expect to see "Oz Nappies Logo" or something similar. I don't believe it is wise to add your tagline to the alt tag. Perhaps if you remove it Google will find a better description or use your meta description. In this case, you use the term "reusable nappies" in your alt tag so that seems to be a factor in the switch.

So, here is the confusing bit Ryan:

Keyphrase - Modern Cloth Nappies = meta description

Keyphrase - Reusabe Nappies = img alt

Both searches page 2 on google.com.au

I performed a Google search for oznappies.com. The resulting link for your home page offered your exact meta description: "Modern Cloth Nappies in Australia - Our affordable nappies are easy to use and environmentally friendly. Our washable nappies are long lasting ..."

Is there another page from your site with this issue? Or am I misunderstanding the issue?
