Content Cluster
A group of interlinked content pieces organized around a central pillar page, where supporting articles cover specific subtopics in depth and link back to the pillar. Content clusters signal topical authority and create logical site architecture.
Content clusters structure your content around topic hubs rather than isolated pages. A pillar page provides a comprehensive overview of a broad topic, while cluster pages dive deep into specific subtopics. Strategic internal linking connects cluster pages to the pillar and to each other, creating a web of related content that search engines can easily understand and evaluate.
For growth teams, content clusters provide a scalable framework for SEO content production. Start by identifying core topics aligned with your product or service. Create a pillar page that broadly covers the topic and serves as the main ranking target for high-volume keywords. Then systematically create cluster content targeting long-tail subtopics that link back to the pillar. This approach concentrates topical authority, improves internal link equity distribution, and creates clear user navigation paths. Track cluster performance holistically by measuring total traffic and conversions across all cluster pages, not just individual page metrics. Well-designed clusters compound in value as each new piece strengthens the entire group.

Core Web Vitals
A set of three Google-defined metrics that measure real-world user experience for loading performance, interactivity, and visual stability. Core Web Vitals are a confirmed ranking factor in Google Search.
Largest Contentful Paint (LCP)
A Core Web Vital that measures the time from page load start until the largest visible content element (image, video, or text block) is rendered on screen. Good LCP is 2.5 seconds or less.
Interaction to Next Paint (INP)
A Core Web Vital that measures the latency of all user interactions (clicks, taps, keyboard input) throughout the page lifecycle, reporting the worst interaction. Good INP is 200 milliseconds or less.
Cumulative Layout Shift (CLS)
A Core Web Vital that measures the total amount of unexpected layout shifts that occur during a page's entire lifespan. Good CLS is 0.1 or less, where layout shifts are calculated from the impact and distance of moving elements.
Time to First Byte (TTFB)
The duration from the user's request to the first byte of the server response reaching the browser. TTFB measures server-side processing speed and network latency, directly impacting all subsequent loading metrics.
Crawl Budget
The number of pages a search engine bot will crawl on your site within a given timeframe, determined by crawl rate limit and crawl demand. Crawl budget optimization ensures important pages are discovered and indexed efficiently.
