```
**Explanation and Rationale:**
1. **``:**
* **Content:** "GATE 2023 Textile Engineering Q26: Double Jersey Weft Knitted Structures | Examprev"
* **Why:** Clearly states the exam, year, question number, and the core topic. It's concise, keyword-rich (`GATE 2023`, `Textile Engineering`, `Double Jersey`, `Weft Knitted Structures`), and includes the brand name for recognition. (Approx. 75 characters)
2. **`<meta name="description">`:**
* **Content:** "Solve GATE 2023 Textile Engineering Question 26 on double jersey weft knitted structures. Understand Rib, Interlock, and Eight lock fabrics in knitting technology. Find the correct answer & explanation."
* **Why:** Expands on the title, includes more keywords (`knitting technology`, `Rib`, `Interlock`, `Eight lock`), highlights the value proposition (solve, understand, explanation), and encourages clicks. (Approx. 185 characters)
3. **`<meta name="keywords">`:**
* **Content:** "textile engineering gate 2023 question 26, double jersey structure, weft knitted structures, knitting technology, rib knit, interlock knit, eight lock knit, textile exam questions, gate textile engineering, knitted fabric types, textile science, examprev"
* **Why:** While less impactful for ranking than in the past, it's still good practice to include a relevant, comprehensive list of terms that users might search for.
4. **`<meta name="robots">`:**
* **Content:** "index, follow"
* **Why:** Instructs search engines to crawl and index this page and follow any links on it. This is the standard for content you want to appear in search results.
5. **`<link rel="canonical">`:**
* **Content:** `https://examprev.com/question/textile-engineering-gate-2023-question-26`
* **Why:** Prevents duplicate content issues by telling search engines that this specific URL is the preferred, original version of the page, even if other URLs might point to the same content.
6. **Open Graph Tags (`og:`):**
* **Why:** These control how the page appears when shared on social media platforms like Facebook, LinkedIn, etc.
* `og:type`: `article` is appropriate for a question page with an explanation.
* `og:url`: The direct URL of the page.
* `og:title`: A compelling title for social sharing, similar to the SEO title.
* `og:description`: A concise and engaging summary for social shares.
* `og:image`: **Crucial for engagement.** Replace the placeholder with an actual image relevant to textile engineering, the GATE exam, or the Examprev brand. A good image significantly increases click-through rates on social media.
* `og:site_name`: Clearly identifies the website.
7. **Twitter Card Tags (`twitter:`):**
* **Why:** These control how the page appears when shared on Twitter.
* `twitter:card`: `summary_large_image` provides a prominent image and text, which is usually best for visibility.
* `twitter:url`, `twitter:title`, `twitter:description`, `twitter:image`: Similar to Open Graph, tailored for Twitter's display. The description includes relevant hashtags for better discoverability on Twitter.
* `twitter:site`: Replace `@ExamprevOfficial` with the actual Twitter handle for Examprev, allowing proper attribution and engagement.
