Server response time is how long a server takes to process a request and begin sending a response, closely related to time to first byte and shaped by hosting and caching.
Email outreach ROI is the revenue a cold email program generates compared with what it costs to run: sourced revenue minus total cost, divided by cost. Because tool fees are low and a booked meeting can be worth thousands, well-run B2B outreach often returns many times its spend.
Page speed is how quickly a web page loads and becomes usable for visitors, measured by metrics like load time and Core Web Vitals, and it affects SEO and conversions.
Largest Contentful Paint, or LCP, is a Core Web Vital that measures how long the largest visible element on a page takes to render, with a good score under 2.5 seconds.
Core Web Vitals are a set of Google metrics measuring real-world user experience: LCP for loading, INP for interactivity, and CLS for visual stability, used as page experience signals.
TTFB, or time to first byte, measures how long a browser waits between requesting a page and receiving the first byte of the response, reflecting server speed and hosting quality.
WordPress hosting is web hosting configured and optimized to run WordPress sites well, ranging from cheap shared plans to premium managed hosting tuned for the platform.
Web hosting is a service that stores your website files on a server connected to the internet, so anyone can load your site by entering its domain, with types from shared to managed and cloud.
Uptime monitoring is a service that regularly checks whether your website is reachable and alerts you when it goes down, measuring availability as a percentage over time.
PHP workers are processes that execute uncached requests to a WordPress site, each handling one request at a time, so the worker count sets how many simultaneous dynamic requests a site can process.
