SEO On-Page SEO Flashcards

24 sample cards from the On-Page SEO deck

Sampled from the end of the deck, so these are different cards from the ones shown on the syllabus page.

1. What is breadcrumb navigation and what are its SEO benefits?

   Breadcrumbs are a secondary navigation trail (e.g., Home > Category > Subcategory > Page) showing a page's location in the site hierarchy. They improve user navigation, reduce bounce rate, add internal links, and can appear as rich results in SERPs via structured data.

2. Name the three common types of breadcrumb navigation.

   Hierarchy-based (shows the site structure/path), Attribute-based (shows attributes of the current page, common in e-commerce filters), and History-based (shows the user's own click path, like a back trail).

3. What is an internal linking strategy and why is it important for SEO?

   An internal linking strategy is the deliberate practice of linking related pages within the same domain. It distributes link equity (PageRank), helps search engines discover and crawl pages, establishes topical relationships, and guides users to relevant content.

4. What is anchor text and what is the best practice for internal link anchors?

   Anchor text is the clickable, visible text of a hyperlink. For internal links, use descriptive, keyword-relevant anchor text that accurately describes the destination page, while keeping it natural and varied rather than exact-match spam.

5. What is a 'pillar page' and 'topic cluster' model of internal linking?

   A pillar page broadly covers a core topic and links out to multiple detailed 'cluster' pages that each address a subtopic; the cluster pages link back to the pillar. This structure signals topical authority and organizes internal links around themes.

6. What is the purpose of image alt text?

   Alt text (alternative text) describes an image for accessibility (read by screen readers) and provides search engines context about the image, helping it rank in image search. It also displays if the image fails to load.

7. What is the best practice for naming image files for SEO?

   Use descriptive, keyword-relevant filenames with hyphens separating words (e.g., 'red-running-shoes.jpg') instead of generic names like 'IMG_1234.jpg', so search engines can understand the image content.

8. Why does image compression matter for on-page SEO?

   Compressing images reduces file size, which speeds up page load times. Faster loading improves user experience and Core Web Vitals (especially Largest Contentful Paint), both of which support better rankings.

9. Compare lossy and lossless image compression.

   Lossy compression permanently removes some image data to achieve much smaller file sizes with some quality loss (e.g., JPEG). Lossless compression reduces file size without discarding data, preserving full quality but yielding larger files (e.g., PNG).

10. Which modern image formats are recommended for web performance, and why?

    WebP and AVIF are recommended because they provide significantly smaller file sizes than JPEG or PNG at comparable quality, improving load speed. AVIF typically compresses even more efficiently than WebP.

11. When should you use JPEG versus PNG?

    Use JPEG for photographs and complex images with many colors where small file size matters and slight quality loss is acceptable. Use PNG for graphics needing transparency or sharp edges/text, such as logos and screenshots.

12. What are the core elements of Video SEO on a page?

    A descriptive keyword-rich title and description, a compelling thumbnail, a transcript/closed captions, structured data (VideoObject schema), fast-loading embedding, and inclusion in a video sitemap so the video is discoverable and eligible for video rich results.

13. Why are transcripts and captions valuable for video SEO?

    Search engines cannot 'watch' video, so transcripts and captions provide crawlable text that conveys the video's content and keywords, improving indexing and relevance while also boosting accessibility and user engagement.

14. What is a VideoObject schema and what does it do?

    VideoObject is a structured data (schema.org) markup that provides search engines with details about a video—such as title, description, thumbnail, upload date, and duration—enabling video rich results and better understanding of the content.

15. What is an image sitemap and when is it useful?

    An image sitemap is an XML sitemap (or image extensions within a sitemap) listing image URLs and metadata. It helps search engines discover images that might otherwise be missed—such as those loaded via JavaScript—improving image search visibility.

16. What information can a video sitemap provide to search engines?

    A video sitemap can specify the video's title, description, thumbnail URL, content/player URL, duration, publication date, and viewing restrictions, helping search engines find and correctly index video content.

17. What does it mean to 'write for users and search engines' simultaneously?

    It means creating content that is genuinely helpful, clear, and engaging for human readers (satisfying intent naturally) while also incorporating relevant keywords, logical structure, and semantic context that search engines can understand—without sacrificing readability for optimization.

18. What is Google's 'people-first' / helpful content principle?

    It is Google's guidance that content should be created primarily to help and satisfy people, demonstrating real expertise and value, rather than being made mainly to rank in search engines. Search-engine-first content risks being demoted.

19. What is readability and which factors improve it?

    Readability is how easy text is to read and understand. It is improved by short sentences and paragraphs, simple vocabulary, active voice, subheadings, bullet lists, adequate white space, and a logical flow of ideas.

20. What does the Flesch Reading Ease score measure, and how is it computed?

    It measures how easy a text is to read on a 0–100 scale (higher = easier). It is computed as $206.835 - 1.015\left(\frac{\text{total words}}{\text{total sentences}}\right) - 84.6\left(\frac{\text{total syllables}}{\text{total words}}\right)$.

21. On the Flesch Reading Ease scale, what score range is considered 'plain English' / easily understood?

    A score of about 60 to 70 is considered plain English, easily understood by 13- to 15-year-old students; scores of 90–100 are very easy, while scores below 30 are very difficult (college-graduate level).

22. What content-formatting techniques improve on-page scannability?

    Descriptive subheadings, short paragraphs (2–3 sentences), bulleted and numbered lists, bold text for key points, tables for comparisons, images/visuals to break up text, and a clear introduction that states the main takeaway early.

23. What is a 'featured snippet' and how can content formatting help earn one?

    A featured snippet is a highlighted answer box at the top of Google results (position zero). Content can be formatted to earn it by directly answering a question in a concise paragraph, using clear step lists for how-to queries, or tables/bullet lists that match the query format.

24. What is the difference between on-page SEO and off-page SEO?

    On-page SEO covers optimizations made within a website—content, title tags, headers, URLs, internal links, images, and technical elements. Off-page SEO covers external signals—primarily backlinks, brand mentions, and social signals—earned from other websites.
