Kev ua kom zoo rau Core Web Vitals tau dhau los ua qhov tseem ceeb rau kev ua tiav ntawm e-lag luam lub vev xaib. Qhia los ntawm Google hauv 2020, Core Web Vitals yog cov txheej txheem ntsuas uas ntsuas cov neeg siv kev paub dhau los ntawm nplooj ntawv web ceev, teb, thiab pom kev ruaj ntseg. Rau cov khw muag khoom online, kev txhim kho cov kev ntsuas no tuaj yeem nqa cov txiaj ntsig tseem ceeb, los ntawm kev txhim kho kev tshawb fawb cav qeb duas kom nce kev hloov pauv.
Peb lub ntsiab tseem ceeb ntawm Core Web Vitals yog:
1. Cov Xim Xim Loj Tshaj Plaws (LCP): Ntsuas lub sijhawm thauj khoom ntawm qhov pom loj tshaj plaws hauv qhov chaw pom thawj zaug.
2. First Input Delay (FID): ntsuas qhov kev teb ntawm nplooj ntawv rau tus neeg siv thawj zaug.
3. Ncua Layout Shift (CLS): ntsuas qhov pom kev ruaj ntseg ntawm nplooj ntawv thaum thauj khoom.
Rau kev lag luam e-lag luam, kev ua kom zoo dua cov yam ntxwv no yog qhov tseem ceeb. LCP ceev ceev kom ntseeg tau tias cov khoom thiab cov duab thauj khoom sai, tso cai rau cov neeg siv khoom pib tshawb nrhiav thiab ua kev yuav khoom yam tsis muaj ncua sijhawm. FID qis kom ntseeg tau tias yuav cov nyees khawm, daim ntawv tshev tawm, thiab cov khoom lim dej teb tam sim ntawd, txo cov neeg siv kev ntxhov siab. Thaum kawg, qhov tsawg kawg nkaus CLS tiv thaiv cov nplooj ntawv los ntawm kev txav mus los yam tsis tau xav txog, muab kev ua haujlwm zoo thiab zoo nkauj.
Cov txiaj ntsig ntawm kev ua kom zoo rau Core Web Vitals hauv e-lag luam muaj ntau yam:
1. Txhim kho SEO: Google suav tias yog Core Web Vitals yog qhov qeb duas, uas tuaj yeem ua rau pom kev zoo dua hauv kev tshawb nrhiav.
2. Kev hloov pauv ntau ntxiv: Cov nplooj ntawv ceev ceev, teb cov nplooj ntawv yuav ua rau cov neeg siv koom nrog, ua kom muaj feem ua tiav kev yuav khoom.
3. Txo tus nqi tso tseg: Ib tus neeg siv kev paub zoo txo qis kev ntxhov siab thiab, yog li ntawd, lub laub tso tseg.
4. Txhim kho kev paub hauv xov tooj: Nrog kev loj hlob ntawm kev yuav khoom hauv xov tooj, Core Web Vitals yog qhov tseem ceeb tshwj xeeb los ua kom muaj kev paub zoo ntawm cov ntxaij vab tshaus me.
5. Ua kom cov neeg siv khoom muaj siab ntseeg ntxiv: Kev ua lag luam zoo siab txhawb kom cov neeg siv khoom rov qab mus rau tom khw.
Txhawm rau txhim kho lub vev xaib e-lag luam rau Core Web Vitals, qee cov tswv yim tuaj yeem siv tau:
- Kev ua kom pom duab zoo: Siv cov qauv niaj hnub xws li WebP thiab compression kom zoo.
- Kev nqis tes ua ntawm tub nkeeg thauj khoom: thauj cov duab thiab cov ntsiab lus raws li xav tau.
- JavaScript thiab CSS Minification: Txo cov ntaub ntawv loj kom nrawm dua.
- Siv CDN (Cov ntsiab lus xa tawm): Kev faib cov ntsiab lus ze rau cov neeg siv.
- Ua ntej cov ntsiab lus saum toj no-the-fold: Ua ntej thauj khoom ntawm cov ntsiab lus pom thaum xub thawj.
- Kev ua kom zoo tshaj plaws font: Siv font-tso: sib pauv thiab preload cov ntawv tseem ceeb.
Nws yog ib qho tseem ceeb uas yuav tsum tau hais txog tias kev ua kom zoo rau Core Web Vitals yuav tsum yog cov txheej txheem tsis tu ncua. Kev ntsuas yuav tsum tau saib xyuas tsis tu ncua thiab hloov kho raws li qhov xav tau, tshwj xeeb tshaj yog tom qab hloov tshiab lub vev xaib tseem ceeb.
Hauv kev xaus, kev nqis peev hauv Core Web Vitals kev ua kom zoo tuaj yeem ua rau muaj txiaj ntsig zoo rau kev lag luam e-lag luam, txhim kho cov neeg siv kev paub thiab kev tshawb fawb cav. Raws li kev lag luam e-lag luam txuas ntxiv zuj zus, muab qhov nrawm, teb, thiab ruaj khov kev lag luam hauv online tau dhau los ua qhov tseem ceeb rau kev ua tiav.
