**Explanation of Tags:**
1. **``**: This is the most crucial SEO element.
* It clearly states the exam, year, question number, and the core topic ("Corrected Fore Bearing & Local Attraction").
* It includes the brand name "ExamPrev" for recognition.
* It's descriptive and optimized for search engine results pages (SERPs).
2. **`<meta name="description">`**: This provides a brief summary of the page content.
* It encourages clicks by describing what the user will learn/practice.
* It incorporates relevant keywords like "GATE Civil Engineering 2013," "corrected fore bearing," "local attraction," "compass traversing," and "surveying MCQ."
3. **`<meta name="keywords">`**: While less impactful for modern SEO, it's good practice to include.
* Lists relevant terms users might search for, covering the topic, exam, and question type.
4. **`<link rel="canonical" href="...">`**: This tells search engines the preferred URL for this content, preventing duplicate content issues.
5. **Open Graph Tags (`og:`):** These control how your page appears when shared on social media platforms like Facebook, LinkedIn, etc.
* `og:title`, `og:description`: Optimized for social sharing, often slightly more engaging than the standard meta description.
* `og:type`: Specifies the type of content (e.g., "article").
* `og:url`: The exact URL of the page.
* `og:site_name`: The name of your website.
* `og:image` (commented out): Highly recommended if you have a relevant image (e.g., ExamPrev logo, a diagram from the question). This makes social shares much more visually appealing.
6. **Twitter Card Tags (`twitter:`):** Similar to Open Graph, these optimize how your page appears when shared on Twitter.
* `twitter:card`: Specifies the type of Twitter card (e.g., "summary" or "summary_large_image" if you have a prominent image).
* `twitter:title`, `twitter:description`: Similar to Open Graph.
* `twitter:image` (commented out): Also highly recommended for visual engagement on Twitter.
* `twitter:site`: Your Twitter handle if you have one.
7. **`<meta name="robots">`**: Explicitly tells search engine crawlers to "index" (include in search results) and "follow" (crawl links on the page). `index, follow` is the default behavior, but explicitly stating it can be useful.
8. **`<meta name="viewport">`**: Essential for responsive web design, ensuring the page displays correctly on various devices.
