Frequently Asked Questions
Meta tags provide structured metadata about a webpage. They help search engines understand content, influence how your pages appear in search results (titles, descriptions), and control social media sharing (Open Graph, Twitter Cards). Proper meta tags improve SEO and click-through rates.
Open Graph (OG) meta tags control how your content appears when shared on platforms like Facebook, LinkedIn, and Pinterest. They define the title, description, image, and type of content. Without OG tags, social networks may pull unoptimized information, resulting in unattractive previews.
The
<meta name="robots"> tag tells search engine crawlers how to index or not index a page, and whether to follow links. Common values: index,follow (default), noindex, nofollow. Incorrect usage can accidentally hide pages from search results.Google sometimes rewrites snippets based on the user query. To increase the chances of your meta description being used, make sure it’s unique, relevant, between 120–155 characters, and accurately summarizes the page content. Missing or duplicate descriptions often get replaced.
The
<link rel="canonical"> tag indicates the preferred URL for content when several versions exist (e.g., duplicate pages). It helps prevent duplicate content issues and consolidates ranking signals to the canonical version.Highlighted Text Extractor – Online Gather Citations From Web
