Meta Tags: Meta tags are HTML elements that provide structured metadata about a webpage, such as its title, description, and keywords. They are used by search engines to understand the content of a page and help with indexing and ranking. Meta tags also play a role in optimizing search engine results by displaying relevant information about a webpage when it appears in search results, influencing click-through rates (CTR). Some common meta tags include the title tag, description tag, and keyword tag.
