Just a small update:
I’m now using the easy recipe plugin, and I can get google’s testing tool to properly validate some of them now. Mostly, I need to either fill in the calories count, or add a picture for it. Once they’re in, the testing tool picks them up.
The downside, of course, is that I don’t have pictures for many of them. And I don’t want to lie about the calorie count (the other way of getting it done) and ‘too many’ isn’t a good answer 😉
As for rich snippets for reviews, I have the SEO ultimate plugin to take care of that. I did have to mess with the ratings plugin (the one that puts the stars in) as it had css that caused problems with the rating, but a quick edit of the plugin to change the css reference from rating to score fixed that. Now I just have to hope that google pay attention to the updates, and start showing the rich snippet additions.
