SEO Issue

This is related to single posts.

In search engines meta descriptions generally begins from where the actual post content starts, by default, if not other changes are made.

in case of this theme, search engine takes bread crumbs, title, author name etc. as meta description by default.

This is related to html tags, I assume, am not very sure though.

Also, when a link on shared on facebook, it generates automatic desription, in that as well, instead of actual content I see bread crumbs, title etc in description.

This is a serious SEO issue, which need to be fixed immediately.

I've checked the results for the News theme and I don't see breadcrumbs in the results - there is the title, then article details. If you want to put in the description the article content, you can use the Meta Description metabox available in the post editor if it is enabled on the SEO tab in the theme settings.

I am using seo plugin by yoast and breadcrumbs plugin by yoast.

So it must be something wrong with these plugins, please see how the search results seems for the News theme using this phrase in Google: site:http://demo.gavick.com/wordpress/news

As you can see - there is no breadcrumbs in the results.
