Core Web Vitals er Googles centrale pr\u00e6stationsm\u00e5linger, der m\u00e5ler indl\u00e6sningshastighed, interaktivitet og visuel stabilitet.

M\u00e5lingerne fokuserer p\u00e5 tre hovedfaktorer: indl\u00e6sningsydeevne, interaktivitet og visuel stabilitet. Med andre ord hj\u00e6lper de websiteejere med at forst\u00e5, hvor hurtigt en side indl\u00e6ses, hvor gnidningsfrit brugerne kan interagere med den, og om indholdet forbliver stabilt under indl\u00e6sningen.<\/p><p>Et websites ydeevne handler ikke kun om, hvor hurtigt en side \u00e5bner. Et website kan indl\u00e6se sit indhold p\u00e5 kort tid, men hvis brugerne skal vente, f\u00f8r de kan klikke p\u00e5 en knap, eller hvis sidens layout \u00e6ndrer sig uventet, kan den samlede oplevelse stadig v\u00e6re d\u00e5rlig. Core Web Vitals hj\u00e6lper med at identificere disse problemer og giver m\u00e5lbare m\u00e5l for at forbedre websitets ydeevne.<\/p><p>Google bruger i \u00f8jeblikket tre Core Web Vitals-m\u00e5linger: Largest Contentful Paint (LCP), Interaction to Next Paint (INP) og Cumulative Layout Shift (CLS). Hver m\u00e5ling m\u00e5ler en forskellig del af brugeroplevelsen, s\u00e5 en forbedring af \u00e9n af dem betyder ikke n\u00f8dvendigvis, at de to andre ogs\u00e5 bliver bedre.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-603a3e6 e-flex e-con-boxed e-con e-parent\" data-id=\"603a3e6\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-ffab792 elementor-widget elementor-widget-text-editor\" data-id=\"ffab792\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<h2>Hvorfor er Core Web Vitals vigtige?<\/h2><p>Et website b\u00f8r give sine bes\u00f8gende en gnidningsfri og p\u00e5lidelig oplevelse.

En udvikler kan for eksempel teste et website p\u00e5 en kraftig computer og konstatere, at det indl\u00e6ses hurtigt. Bes\u00f8gende, der bruger \u00e6ldre mobilenheder eller langsommere internetforbindelser, kan dog opleve betydeligt l\u00e6ngere indl\u00e6sningstider.<\/p><p>Disse forskelle g\u00f8r det vigtigt at overv\u00e5ge ydeevnen.

Google bruger signaler om sideoplevelse i sine rangeringssystemer, men gode Core Web Vitals-resultater garanterer ikke h\u00f8jere placeringer. Relevant indhold og mange andre faktorer er fortsat vigtige. Derfor b\u00f8r forbedring af disse m\u00e5linger ses som en del af en bredere strategi for at opbygge et nyttigt, tilg\u00e6ngeligt og p\u00e5lideligt website.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-598ac2f e-flex e-con-boxed e-con e-parent\" data-id=\"598ac2f\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-def6c44 elementor-widget elementor-widget-text-editor\" data-id=\"def6c44\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<h2>Hvad er de tre Core Web Vitals-m\u00e5linger?<\/h2><p>Hver Core Web Vitals-m\u00e5ling fokuserer p\u00e5 et bestemt aspekt af et websites ydeevne.

Sidens baggrund og navigationsmenu vises m\u00e5ske n\u00e6sten med det samme, men hovedoverskriften eller det fremh\u00e6vede billede kan tage flere sekunder om at indl\u00e6se. I den situation kan den bes\u00f8gende have indtryk af, at siden stadig indl\u00e6ses, selvom nogle af dens elementer allerede er synlige. En god LCP-v\u00e6rdi b\u00f8r v\u00e6re 2,5 sekunder eller mindre. Ligger v\u00e6rdien mellem 2,5 og 4 sekunder, skal siden forbedres.

I mods\u00e6tning til First Input Delay (FID), som kun m\u00e5lte forsinkelsen, f\u00f8r browseren begyndte at behandle den f\u00f8rste interaktion, tager INP h\u00f8jde for den samlede interaktionsoplevelse i hele sidens levetid. En god INP-v\u00e6rdi er 200 millisekunder eller mindre. V\u00e6rdier over 200 og op til 500 millisekunder skal forbedres, mens v\u00e6rdier over 500 millisekunder betragtes som d\u00e5rlige.<\/p><p style=\"padding-left: 40px;\">JavaScript er en almindelig \u00e5rsag til d\u00e5rlig INP, fordi browseren kan v\u00e6re n\u00f8dt til at udf\u00f8re scripts, f\u00f8r den kan reagere p\u00e5 brugerens input og vise en opdatering. Langvarige opgaver kan forhindre browseren i at behandle interaktioner hurtigt.<\/p><p style=\"padding-left: 40px;\">For at forbedre INP kan udviklere bruge flere teknikker:<\/p><ul><li style=\"list-style-type: none;\"><ul><li><span style=\"color: #a26f9a;\">Reducer un\u00f8dvendig JavaScript:<\/span> Fjern ubrugt kode, og undg\u00e5 at indl\u00e6se scripts, der ikke er n\u00f8dvendige for den aktuelle side.<\/li><li><span style=\"color: #a26f9a;\">Opdel lange opgaver:<\/span> Del store JavaScript-opgaver op i mindre opgaver, s\u00e5 browseren f\u00e5r flere muligheder for at behandle brugerinteraktioner.<\/li><li><span style=\"color: #a26f9a;\">Optimer event handlers:<\/span> Hold funktioner, der er knyttet til interaktioner, s\u00e5 enkle og effektive som muligt.<\/li><li><span style=\"color: #a26f9a;\">Undg\u00e5 un\u00f8dvendige DOM-opdateringer:<\/span> Hvis for mange elementer opdateres p\u00e5 \u00e9n gang, kan det \u00f8ge renderingstiden og forsinke den n\u00e6ste visuelle opdatering.<\/li><li><span style=\"color: #a26f9a;\">Reducer tredjepartsscripts:<\/span> Analysev\u00e6rkt\u00f8jer, annoncescripts og indlejrede tjenester kan bruge behandlingsressourcer og p\u00e5virke responsiviteten.<\/li><\/ul><\/li><\/ul><p style=\"padding-left: 40px;\">At forbedre INP kr\u00e6ver mere end blot at reducere den samlede st\u00f8rrelse af JavaScript-filerne.
