TTFB slow — server response delay measured

Time To First Byte (TTFB) is how long your server takes to begin sending the page to a visitor's browser after they click a link. Yours is currently slower than recommended thresholds. A slow TTFB delays everything that follows — images, text, and interactive elements all load later than they should. It directly harms your Core Web Vitals scores (which Google uses as a ranking factor), increases bounce rates, and costs conversions, especially on mobile connections. Common fixes include enabling caching so the server doesn't rebuild the page from scratch on every visit, using a content delivery network (CDN) to serve pages from a location closer to each visitor, and reviewing any slow database queries or third-party services that run before the page starts loading.
