Cannibalization of keywords is what?

Answer: When multiple pages on a site are optimized for the same keywords.

Keyword cannibalization occurs when several pages on the same website target and rank for the exact same keywords. This confuses search engines about which page is most relevant, potentially diluting authority and causing pages to compete against each other. It can lead to lower rankings for all involved pages rather than a single strong ranking.

What should you take to undo a manual link penalty?

Answer: Remove or disavow all links that do not appear to be editorially given, and file a reconsideration request.

To recover from a manual link penalty, Google requires webmasters to actively clean up or disavow unnatural or spammy backlinks. This involves identifying and removing problematic links or using Google's Disavow Tool to tell Google to ignore them. After demonstrating a good-faith effort to fix the issue, a reconsideration request must be submitted to Google for review.

Which of these should you use to your advantage when creating various filters or sort orders for products on your website to reduce the risk of thin or duplicate content?

Answer: Rel="canonical"

The `rel="canonical"` tag is used to tell search engines which URL is the preferred or 'canonical' version of a page among a set of duplicate or very similar pages. When dealing with filtered or sorted product listings that generate many URLs with similar content, implementing `rel="canonical"` helps consolidate ranking signals to the main product category page, preventing issues with thin or duplicate content.

What is the purpose of the HTTP header Vary: User-Agent?

Answer: It tells caching servers that a site's content varies by user agent.

The `Vary: User-Agent` HTTP header instructs caching servers (like CDNs or proxies) that the content served for a particular URL might differ based on the user's browser or device (the 'User-Agent'). This is crucial for sites that implement dynamic serving, ensuring that the correct version of the page (e.g., mobile vs. desktop) is delivered and cached appropriately for each user agent.

A mobile subdomain: what is it?

Answer: A subdomain that the web server will send users to based on their user agent.

A mobile subdomain (e.g., `m.example.com`) is a separate version of a website specifically designed for mobile devices. When a user accesses the main site from a mobile device, the web server detects their user agent and redirects them to the mobile subdomain, which serves content optimized for smaller screens and touch interfaces.

How can Penguin be recovered from?

Answer: Clean up links from web directories, article directories, countries where you don't do business and where you have too much rich anchor text, and then wait

Google's Penguin algorithm targets websites with manipulative or spammy link profiles. To recover, webmasters must identify and clean up low-quality, unnatural, or overly optimized backlinks, often involving disavowing them. Unlike manual penalties, Penguin updates are algorithmic, so recovery typically involves cleaning up the link profile and then waiting for Google to re-crawl and re-evaluate the site during a subsequent Penguin refresh.

When should you use the robots noindex meta tag?

Answer: To prevent pages from appearing in search results

The `noindex` meta tag or `X-Robots-Tag` HTTP header instructs search engines not to include a specific page in their search index. This is useful for pages that you don't want users to find via search, such as internal administrative pages, thank you pages, or pages with duplicate or low-quality content that you still want accessible on the site.

Does Google consider the position of information on a page?

Answer: Yes; placement on the page says something about the importance of the content.

Google's algorithms do consider the placement of content on a page. Information placed higher up in the main content area (above the fold) is generally perceived as more important and relevant than content buried at the bottom or in sidebars. This helps search engines understand the primary focus and hierarchy of information on a page.

Which of these should you choose when implementing pagination for products on your website to reduce the danger of duplicate content or thin content?

Answer: Rel=prev/next

Historically, `rel="prev"` and `rel="next"` tags were recommended by Google to indicate paginated content, helping search engines understand the sequence of pages and consolidate ranking signals. While Google announced in 2019 that they no longer use these for indexing, they can still be useful for other search engines and for maintaining a clear site structure, making them the most appropriate choice among the given options for managing pagination.

Responsive web design: what is it? ​

Answer: A site design that uses CSS to dynamically adapt the HTML to fit the user's device and screen size.

Responsive web design is an approach that makes web pages render well on a variety of devices and screen sizes. It uses flexible layouts, images, and CSS media queries to adapt the content and layout dynamically, providing an optimal viewing experience across desktops, tablets, and mobile phones from a single HTML codebase.

What are rel prev/next tags used for?

Answer: All of the above

The `rel="prev"` and `rel="next"` attributes were historically used to signal to search engines that a series of pages were related and part of a paginated set. This helped consolidate ranking signals, eliminate concerns about perceived duplicate content across paginated URLs, and allowed publishers to identify these groups. Although Google deprecated their use for indexing in 2019, these were their intended purposes.
