Meta tags are invisible tags that provide data about your page to search engines and website visitors.
In short, they make it easier for search engines to determine what your content is about, and thus are vital for SEO.
Meta tags are placed in the <head> section of a HTML document, and so they need to be coded in your CMS. This can be easier or harder depending on the platform that powers your website: an “out of the box” solution like WordPress will have a dedicated section for meta tags like canonical links or meta descriptions.
