The harder half of the bank: second-order concepts and the details that separate someone who has read about SEO from someone who has fixed it. Crawl budget, hreflang, soft 404s, faceted navigation, JavaScript rendering, INP versus FID, priority hints, lazy hydration, and how the third-party authority metrics are calculated.

8 of the 39, with the answer and the explanation hidden until you open each one.
Answer: D. LCP is most affected by slow server response times, render-blocking resources, and large images or videos. Optimizing these elements significantly improves LCP.
Answer: D. Crawling is when search engines discover and scan pages. Indexing is when they analyze and store the content in their database for potential display in search results.
Answer: D. Dwell time is the amount of time a user spends on a page after clicking from search results before returning to the SERP. Longer dwell time often indicates quality content.
Answer: D. A soft 404 occurs when a server returns a 200 OK status for a non-existent page instead of a proper 404. This confuses search engines and should be fixed to return proper 404 codes.
Answer: D. Preloading uses <link rel='preload'> to tell the browser to fetch critical resources early in the page load process, improving performance by loading key assets sooner.
Answer: D. Edge SEO involves implementing SEO modifications at the CDN/edge layer, allowing changes without altering the origin server. It's useful for dynamic redirects, A/B testing, and headers.
Answer: D. TTI measures how long it takes for a page to become fully interactive and reliably respond to user input. Good TTI is under 3.8 seconds. Long JavaScript tasks can delay TTI.
Answer: C. DA is calculated by Moz using multiple factors including linking root domains, total number of links, and other proprietary metrics. It uses machine learning to find the algorithm that best correlates with search rankings.
