1. What are the most critical on-page SEO factors you consider when optimizing a page?

The key on-page SEO factors include:

• Title tag: Make sure it’s relevant to the content and includes the main keyword.
• Meta description: A short summary that encourages users to click through.
• Headers (H1, H2, etc.): Use headings to structure the content and include keywords naturally.
• Keyword placement: Use the primary and related keywords throughout the page, but don’t overdo it.
• Content quality: Ensure the content is unique, informative, and answers user questions.
• Internal links: Link to other relevant pages on your site to guide users and search engines.
• URL structure: Keep URLs short, descriptive, and include keywords if possible.
• Mobile-friendliness: Ensure the page is responsive and works well on all devices.
• Page speed: Fast-loading pages provide a better user experience and rank higher.

2. How do you optimize a webpage’s title tag for SEO?

To optimize a title tag:

• Include the main keyword: Place your primary keyword near the beginning of the title.
• Keep it short and clear: Aim for around 50-60 characters so it doesn’t get cut off in search results.
• Make it descriptive: It should tell users what the page is about.
• Engage users: Add something compelling that encourages users to click, like “Best,” “Guide,” or “Tips.”

3. What is keyword cannibalization, and how do you fix it?

Keyword cannibalization happens when multiple pages on your site compete for the same keyword, causing confusion for search engines. To fix it:

• Audit your content: Identify which pages are targeting the same keyword.
• Merge or update content: If two pages are similar, combine them into one comprehensive page.
• Use different keywords: Ensure each page targets a unique keyword or variation.
• Internal linking: Make sure to link related pages properly, giving priority to the most important page.

4. How would you go about optimizing a website’s internal linking structure?

To optimize internal linking:

• Link relevant pages: Connect related pages to help users find more information and spread link equity.
• Use descriptive anchor text: The clickable text should describe the page it links to, ideally including keywords.
• Ensure logical flow: The most important pages should be easily accessible, especially from the homepage.
• Avoid too many links: Don’t overdo it—only link when it makes sense for the user experience.

5. How important is page speed for on-page SEO, and how would you improve it?

Page speed is very important because it affects both user experience and search rankings. To improve it:

• Optimize images: Compress and resize images without losing quality.
• Use browser caching: Store parts of your website so it loads faster on repeat visits.
• Minify CSS, JavaScript, and HTML: Remove unnecessary code to reduce page size.
• Enable a Content Delivery Network (CDN): A CDN distributes content to servers worldwide, making your site load faster for users.
• Reduce server response time: Ensure your hosting is fast and reliable.

6. What role does meta description play in SEO, and how do you optimize it?

Meta descriptions don’t directly impact rankings but can influence click-through rates (CTR), which can indirectly affect SEO. To optimize a meta description:

• Keep it under 160 characters: So it fits within search result limits.
• Include the main keyword: Make it clear what the page is about.
• Make it engaging: Write a summary that entices users to click through, like a call to action (“Learn more,” “Discover”).
• Unique for each page: Every page should have a different meta description that accurately describes its content.

7. How do you approach optimizing images for SEO?

To optimize images:

• Use descriptive file names: Name the image files with relevant keywords (e.g., “blue-widget.jpg” instead of “IMG123.jpg”).
• Compress images: Reduce file size to ensure fast page loading without losing quality.
• Add alt text: Describe the image using relevant keywords. This helps search engines and improves accessibility.
• Choose the right format: Use modern formats like WebP or optimized JPEG/PNG for better performance.
• Use responsive images: Ensure images scale properly on different devices.

8. What role does keyword density play in modern SEO?

Keyword density refers to how often a keyword appears on a page compared to the total word count. In modern SEO, keyword density isn’t as important as it used to be. Search engines focus more on context and content quality than the frequency of keywords. However, it’s still important to include keywords naturally without overstuffing. Instead of focusing on density, use related terms and synonyms to create relevant, user-friendly content.

9. How do you optimize a webpage for featured snippets?

To optimize for featured snippets:

• Answer questions clearly: Use short, concise answers (40-50 words) at the top of your content.
• Use headers and lists: Format information using bullet points, numbered lists, or tables.
• Target question-based keywords: Use phrases like “how,” “what,” and “why” in headings or within the content.
• Structured data: Add schema markup to help search engines understand the page content.
• Provide detailed and useful content: Make sure the rest of the content is thorough and informative to support the snippet.

10. How do you handle duplicate title tags across multiple pages?

To handle duplicate title tags:

• Create unique titles: Ensure each page has a distinct, relevant title that reflects the page’s content.

11. What are the best practices for writing SEO-friendly URLs?

For SEO-friendly URLs:

• Keep them short and descriptive: Use a few relevant words to describe the page.
• Include a keyword: Use the primary keyword in the URL.
• Avoid unnecessary words: Remove stop words like “and,” “the,” and “of.”
• Use hyphens, not underscores: Separate words with hyphens for better readability.
• Lowercase letters: Use lowercase letters to avoid confusion with case sensitivity.

12. How does user experience (UX) influence on-page SEO?

User experience is critical to SEO because it affects how users interact with your site. A good UX can:

• Increase engagement: More time on the page and lower bounce rates signal to Google that your content is valuable.
• Improve navigation: Easy-to-use menus and clear calls to action guide users through the site, improving performance.
• Boost mobile-friendliness: A responsive design ensures your site works well on all devices, a key ranking factor.

• Fast loading: Ensure the page loads quickly for better user experience and ranking.
• Clear call-to-action (CTA): Make it easy for users to take the desired action (e.g., sign up, buy, etc.).

18. How does Google treat nofollow vs. follow internal links?

• Follow links: These pass “link juice” or ranking power to the page being linked to, helping it rank better.
• Nofollow links: These tell Google not to pass ranking power to the linked page. Nofollow links are typically used for paid links or user-generated content like blog comments.
• Internal nofollow links: These should be used sparingly, as most internal links should be follow links to help Google crawl your site effectively.

19. What is the relationship between Core Web Vitals and on-page SEO?

Core Web Vitals measure how users experience your site and are part of Google’s ranking factors:

• Largest Contentful Paint (LCP): Measures how quickly the main content loads—affects user experience and SEO.
• First Input Delay (FID): Measures the time it takes for the site to become interactive—helps ensure good user engagement.
