I have a large site and I have a question over meta tags.
For example, I have meta title, description and keywords as has always been known, these labels are essential for SEO.
With the facebook new open graph I have this in my head:
<meta property="og:title" content="Advertising">
<meta property="og:description" content="description advertising">
<meta property="og:type" content="website">
<meta property="og:url" content="url">
<meta property="og:site_name" content="mi_site_name">
.
.
.
and more meta og: if you want add more....
My questions are:
Can I work with both (meta tags for google and meta tags open graph for facebook)? how it affects the seo? Google penalizes you if you add og meta tags? is best to use the meta keywords for google or use open graph for facebook?
Thank you
You can have meta tags for Google and the other search engines as well as Facebook in the same page without one affecting the other. Having Facebook meta tags will not affect your rankings (and for that matter neither will regular meta tags) or get you penalized.
