Schema
Schema refers to code used by search engines to help them understand your content. Good Gallery websites include schema information. That information is created dynamically and automatically using data you already provide.
Because we use schema information in our code, that in turn improves the way your website information is displayed in search engine results.
Scheme information is also known as structured data. We also provide Open Graph data.
SEO
Although schema information and structured data don’t directly affect rankings, the improved characteristics of the way your information in search engines does affect clickthroughs and that in turn can positively affect your rankings and conversions.
