Search Engine Optimization Syllabus

What is keyword cannibalization?

Keyword cannibalization occurs when multiple pages on the same site target the same keyword, causing them to compete with each other and dilute ranking signals, often lowering overall performance for that term.

What is keyword density and what is a commonly recommended range?

Keyword density is the percentage of times a keyword appears relative to total word count: $$\text{Density} = \frac{\text{Keyword occurrences}}{\text{Total words}} \times 100\%$$ A natural range of roughly 1-2% is commonly recommended to avoid keyword stuffing.

What is content optimization in SEO?

Content optimization is the process of improving content so it ranks well and satisfies user intent, involving keyword placement, readability, structure with headings, relevant media, internal links, and comprehensive coverage of the topic.

What does E-E-A-T stand for in Google's content quality guidelines?

E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trustworthiness, which are signals Google uses to assess content quality, especially for YMYL (Your Money or Your Life) topics.

Why is keyword placement in the first 100 words important for content optimization?

Placing the primary keyword early (within the first 100 words) helps search engines quickly understand the page topic and signals relevance to both crawlers and readers.

What is the purpose of the HTML title tag in SEO?

The title tag (<title>) defines the clickable headline shown in the SERP and browser tab. It is a strong on-page ranking signal and should be unique, descriptive, include the primary keyword, and stay roughly under 60 characters.

What is the meta description tag and does it directly affect rankings?

The meta description is an HTML tag summarizing a page's content (about 150-160 characters) shown in the SERP. It does not directly affect rankings but influences click-through rate by enticing users to click.

What is the role of heading tags (H1-H6) in SEO?

Heading tags structure content hierarchically. The H1 should describe the main topic (one per page), and H2-H6 organize subsections, helping search engines and users understand content structure and improving readability.

What is alt text (the alt attribute) and why does it matter for SEO?

Alt text is an HTML attribute describing an image's content. It improves accessibility for screen readers, helps images rank in image search, and provides context to crawlers that cannot 'see' images.

What makes an SEO-friendly URL structure?

An SEO-friendly URL is short, readable, uses hyphens to separate words, includes relevant keywords, avoids unnecessary parameters and stop words, and uses lowercase letters (e.g., /blue-running-shoes).

Why should hyphens rather than underscores be used in URLs?

Search engines treat hyphens as word separators but read underscores as joiners, so 'blue-shoes' is parsed as two words while 'blue_shoes' may be read as one. Hyphens are recommended for readability and indexing.

What is a canonical URL and what problem does it solve?

A canonical URL, specified via the rel="canonical" tag, tells search engines which version of duplicate or similar pages is the preferred one to index, preventing duplicate-content dilution of ranking signals.

What is internal linking?

Internal linking is the practice of linking from one page of a website to another page on the same domain, helping distribute link equity, aid navigation, and help search engines discover and understand site structure.

What is anchor text and why is it important?

Anchor text is the visible, clickable text of a hyperlink. Descriptive, keyword-relevant anchor text helps search engines understand the topic of the linked page and improves both SEO and user experience.

What is 'link equity' (link juice)?

Link equity is the ranking value or authority passed from one page to another through hyperlinks. Both internal and external links distribute this equity, influencing the target page's ability to rank.

What is a backlink?

A backlink is an incoming hyperlink from one website to another. Backlinks act as 'votes of confidence' and are a major off-page ranking factor, with quality and relevance mattering more than sheer quantity.

What is the difference between a dofollow and a nofollow link?

A dofollow link passes link equity/authority to the target page and can influence its rankings, while a nofollow link (with rel="nofollow") tells search engines not to pass ranking authority, though it may still drive traffic.

What are three effective white-hat backlink building strategies?

Creating high-quality linkable content, guest blogging on relevant authoritative sites, and digital PR/outreach. Others include broken link building, resource page link building, and earning editorial mentions.

Why is backlink quality more important than quantity?

A few links from high-authority, topically relevant sites pass more ranking value and trust than many links from low-quality or spammy sites, which can even trigger penalties. Search engines weigh relevance and authority heavily.

What are social media signals in the context of SEO?

Social media signals are the engagement metrics (shares, likes, comments) a page receives on social platforms. They are not direct ranking factors but can increase content visibility, traffic, and the likelihood of earning backlinks.

What is guest blogging and how does it help SEO?

Guest blogging is writing and publishing articles on other websites in your niche. It helps SEO by earning backlinks, driving referral traffic, building brand authority, and expanding audience reach.

What is website speed and why is it an SEO factor?

Website speed is how quickly a page loads and becomes interactive. It is a confirmed ranking factor because faster pages improve user experience, reduce bounce rate, and are favored by Google's page-experience signals.

What are Google's Core Web Vitals?

Core Web Vitals are user-experience metrics: LCP (Largest Contentful Paint, loading), INP (Interaction to Next Paint, interactivity, which replaced FID), and CLS (Cumulative Layout Shift, visual stability).

What is the recommended 'good' threshold for Largest Contentful Paint (LCP)?

A good LCP score is $\leq 2.5$ seconds. Between 2.5 and 4.0 seconds needs improvement, and $> 4.0$ seconds is considered poor.

Name three common techniques to improve website speed.

Compressing and optimizing images, enabling browser caching, and minifying CSS/JavaScript. Others include using a CDN, reducing server response time, and lazy-loading media.

What is mobile optimization and why does it matter for SEO?

Mobile optimization ensures a site displays and functions well on mobile devices (responsive design, readable text, fast load). It matters because Google uses mobile-first indexing and most searches occur on mobile devices.

What is Google's mobile-first indexing?

Mobile-first indexing means Google predominantly uses the mobile version of a site's content for indexing and ranking, so the mobile version must contain the same important content as the desktop version.

What is crawlability and indexing in technical SEO?

Crawlability is a search engine's ability to access and crawl a site's pages via bots, while indexing is the storing and organizing of those crawled pages in the search engine's database so they can appear in results. A page must be both crawled and indexed to rank.

What is the purpose of a robots.txt file and an XML sitemap?

A robots.txt file instructs crawlers which URLs they may or may not access, while an XML sitemap lists a site's important URLs to help search engines discover and crawl them efficiently.

What are HTTPS and SSL, and how do they relate to SEO?

SSL (Secure Sockets Layer) is the encryption technology that secures data between browser and server, and HTTPS is the resulting secure protocol. Google treats HTTPS as a lightweight ranking signal, and secure sites build user trust.

What is Google My Business (Google Business Profile) and why is it important for local SEO?

Google Business Profile (formerly Google My Business) is a free tool for managing a business's presence on Google Search and Maps. It is important for local SEO because it powers the local pack, provides NAP (Name, Address, Phone) info, hours, reviews, and boosts local visibility.
