Schema Markup 101: Boost Your SEO & Improve Search
Schema markup is code you add to your webpage that tells a search engine what your content is about.
If you can tell Google the meaning behind your content, it can show your content to the right people. This can lead to an increase in organic traffic and improved conversions.
When done correctly, schema markup creates a web of context that helps search engines help you by improving your click-through rate (CTR) and conversions.
