I am doing SEO for a website which have offices in two locations in USA and also in UK. I would like to use microdata for the organisation using free tool(tools dot seochat dot com/tools/brand-organization-schema-generator/) for rich snippet generators. I have already placed meta tags on the home page. My doubt is whether should i use rich snippet tags for both locations of usa and also uk. where should i place the tags on the home page. can i place them after on page meta-tags? how are are microdata format tags helpful in seo?
