Users abandon slow sites and rarely return. The good news: because WordPress gives you full control over hosting, caching, code, and content delivery, it is the platform where smart optimization makes the biggest measurable difference.  \nCO R E W E B V ITA LS : YO U R P E R FO RMA NC E TA RG ETS  \nMETRIC GOOD NEEDS WORK POOR  \n\n| LCP: Largest Contentful Paint  Under 2.5s  2.5s – 4.0s |  | | Over 4.0s |\n| --- | --- | --- | --- |\n| INP: Interaction to Next Paint  Under 200ms  200 – 500ms |  | | Over 500ms |\n| CLS: Cumulative Layout Shift  Under 0.1  0.1 – 0.25 |  | | Over 0.25 |\n| TTFB: Time to First Byte  Under 200ms  200 – 800ms\u003Cbr>Google officially calls TTFB “good” at under 800ms, but high-performing WordPress sites target LCP under 1 . 5s, INP under 100ms, and TTFB under 200ms. These are the thresholds that separate fast sites from great ones. |  | | Over 800ms |\n| HOW TO US E T H IS C H EC K L IST\u003Cbr>Work through each step in order: they are ordered by impact and dependency. Hosting and caching (Steps 2 and 3) have the largest impact and must be addressed before any frontend optimization, because no amount of image compression can overcome a one-second server response time.

Without a baseline, you are guessing which issues matter most for your specific site. Every site has different bottlenecks: one site’s biggest issue is images, another ’s is TTFB, another ’sis JavaScript.
