Hey Beau
Thanks for your reply.
We never received anything from Google in Google Webmaster tools. One day the site was gone in the serp with no explanation. That was on 11 August. Since then we have done a lot of things in Google Webmaster tools to see if that would help. There were no major things, but we have done everything we can and no there are nothing left to do. Yesterday, the site as back on track in Google. I can't say why, but positive thinking (ability to look for solutions and not anybody to blame) I believe are the most important reasons why we are back.
We have not liberally used anything to mark up our site with structural data before. The only thing we could find that might have helped us with structural data was a plugin Author H review which I find very good. However my intention is so structure up the entire site with structural data now.
I read the recommended article about structural data (thanks, it was really interesting). I'm no experted in it, nor is my web developer. Hence I have been thinking of contacting a Schema.org expert. What do you think, would that be a good idea? The more I read about schema.org the more it triggers my interest and the more I realize that it could be good to get some help.
In google webmaster tools we still have 4 errors regarding Structural data. However when we test it in their own tools everything works. IN the control panel we have added http: https: www.http www.https. For some reason Google shows different results regarding indexed pages and structural data and site maps depending which of the http versions you're looking at. The structural data is now back and we have managed to increase it.
Thanks a lot for your hel Beau. Your questions and answers helped us to start looking more at structural data. It was a great relief yesterday when we were back in the search results again. I hope it will stay that way.
Do you think it's worth spending time and resources to contact a schema.org consultant who can help us mark up the entire page with structural data?
Have a nice day!
