Hinting mus nrhiav xyaw tus Preferred Version ntawm ib daim ntawv
Thaum koj khiav cov ntaub ntawv uas tau tsav los sis muaj lwm yam txheej xwm vim li cas ib daim ntawv sib txuas ua ke nws tseem ceeb uas yuav tsum qhia rau cov kev tshawb fawb xyaw uas luam yog daim ntawv luam, lossis hauv lub jargon, daim ntawv "canonical". Thaum lub cav tshawb nrhiav koj cov nplooj ntawv nws tuaj yeem qhia thaum twg cov ntsiab lus tau duplicated. Yog tias tsis muaj xov xwm ntxiv, lub cav tshawb fawb yuav txiav txim siab seb leej twg zoo tshaj plaws raws li qhov xav tau ntawm lawv cov neeg muas zaub. Qhov no tej zaum yuav zoo, tab sis kuj muaj ntau zaus ntawm kev tshawb fawb xyaw cov nplooj ntawv qub thiab cov nplooj ntawv qub vim lawv xaiv cov ntaub ntawv tsis raug cai raws li canonical.
Yuav Qhia Tau Dab Tsi Rau Lub Vaj Kaj Siab
Nws yog heev yooj yim los qhia kev tshawb fawb xyaw cov ntsiab lus ntawm cov xov xwm hauv cov ntaub ntawv hauv koj cov ntaub ntawv. Muab cov HTML hauv qab no nyob ze rau saum koj lub taub hau ntawm txhua nplooj ntawv uas tsis tuaj yeem ua tau:
Yog hais tias koj muaj kev nkag tau mus rau HTTP headers (xws li nrog .htaccess los yog PHP) koj tuaj yeem teev cov ntsiab lus canonical ntawm cov ntaub ntawv uas tsis muaj lub taub hau HTML, xws li PDF. Ua li no, muab cov hau kev rau cov nplooj ntawv uas tsis yog-canonical li no:
Txuas: < URL ntawm nplooj ntawv canonical >; rel = "canonical"
Cas tus Canonical Tag Ua Hauj Lwm thiab Thaum Tsis Ua
Cov ntaub ntawv metabolism canonical yog siv raws li tus hint mus tshawb xyaw rau cov nplooj ntawv yog tus tswv. Kev tshawb fawb xyaw siv qhov no los hloov lawv qhov kev txheeb xyuas los mus siv cov ntawv luam raws li daim ntawv luam, thiab thaum lawv xa cov kev tshawb nrhiav lawv xa cov nplooj ntawv lawv ntseeg tias yog canonical.
Tab sis cov nplooj ntawv uas koj qhia tau tias yuav tsis yog qhov nplooj uas tshawb nrhiav xyaw.
Muaj ntau ntau yam ua rau qhov no tshwm sim:
- Yog tias qhov koj tau hais qhia yog 404 tsis pom, kev tshawb fawb xyaw yuav sim nrhiav ob qhov tseem ceeb tshaj plaws qhov URL kom xa tuaj
- Yog tias qhov tshawb nrhiav cav ntseeg tias koj lub vas sab tau raug ntxiv los ntxiv ib txoj cai fake canonical lawv yuav tsis siv nws (ntawm chav kawm, koj yuav muaj teeb meem loj dua hauv qhov xwm txheej no)
- Yog tias koj tso qhov txuas rau hauv daim pib, los yog muaj qee yam ntseeg tias TSIS tsis tau kaw. Qhov no yog vim muaj ntau lub vas sab pub rau cov neeg siv los txhim kho cov ntsiab lus ntawm nplooj ntawv (hauv lub CIM TSWV TSEV), thiab thaum nqus cov kab lus uas siv tau pom los yuav muaj kev tsis zoo thiab.
Dab tsi yog qhov Rel = Canonical Tag Tsis yog
Ntau tus neeg ntseeg hais tias yog tias koj ntxiv rel = canonical txuas mus rau ib nplooj ntawv ces cov nplooj ntawv yuav raug xa mus rau lub canonical version, xws li nrog rau HTTP 301 redirect. Qhov no tsis yog qhov tseeb. Qhov txuas = canonical txuas muab cov ntaub ntawv rau kev tshawb xyaw, tab sis nws tsis cuam tshuam li cas cov nplooj ntawv tau teev lus pom los yog nws tsis ua qhov kev hloov ntawm cov neeg siv khoom qib .
Lub canonical txuas yog, kawg, ib tug hint xwb. Kev tshawb fawb xyaw tsis tas yuav hawm nws. Feem ntau cov kev tshawb fawb xyaw siv zog ua rau cov neeg xav tau tswv yim, tab sis thaum hnub kawg, qhov kev tshawb fawb nrhiav tau yog lawv ua dab tsi, thiab yog lawv tsis xav ua hauj lwm rau koj cov nplooj ntawv canonical, lawv yuav tsis ua.
Thaum twg siv cov Canonical Txuas
Raws li kuv tau hais saum toj no, koj yuav tsum siv qhov txuas rau txhua phab tib yam uas tsis muaj peev xwm. Yog tias koj muaj nplooj ntawv uas zoo sib xws, tiam sis tsis zoo tib yam, nws qee zaum ua rau muaj kev hloov ntau dua ib leeg, txawv dua li ua ib qho canonical.
Nws zoo rau kos ob nplooj ntawv uas tsis zoo tib yam li canonical. Lawv yuav tsum zoo sib xws, tiam sis koj yuav tsum tsis txhob yoojyim rau tag nrho cov nplooj ntawv rau koj qhov home page. Canonical txhais tau hais tias cov nplooj ntawv yog tus qauv ntawm daim ntawv ntawd, tsis muaj kev sib txuas ntawm tus thawj ntawm koj qhov chaw.
Kuv xav tias nws tseem ceeb heev uas rov qab hais tias qhov kawg me ntsis - koj yuav tsum tsis txhob qhia tag nrho koj cov nplooj ntawv rau hauv koj qhov home page raws li cov phab ntsa kab tshab txawm tias koj yuav raug li cas. Ua qhov no, txawm tias muaj kev huam yuaj, tuaj yeem ua rau txhua phab uas tsis yog canonical (xws li txhua nplooj ntawv uas tsis yog koj qhov home page thiab muaj qhov txuas = qhov txuas ntawm nws) kom raug muab tshem tawm ntawm qhov tshawb nrhiav cav.
Qhov no tsis yog Google (lossis Bing los yog Yahoo! los yog lwm yam tshawb nrhiav cav) ua siab phem. Lawv tabtom ua raws li koj tau hais kom lawv ua - xaiv txhua nplooj ntawv ib qho ntawm koj qhov home page thiab xa tag nrho cov qhabnias rau phab ntawv ntawd. Ces thaum cov neeg tuaj yeem cuam tshuam xaus rau ntawm koj qhov home page tsis muaj ntaub ntawv ntau, cov nplooj ntawv yuav tsis nrov thiab yuav poob rau hauv kev tshawb nrhiav. Txawm hais tias koj txhim kho qhov teeb meem, koj tuaj yeem tua koj cov txiaj ntsig kev tshawb nrhiav rau lub hlis tom qab thiab tsis muaj qhov lees paub tias koj qhov chaw ua haujlwm yuav rov qab tau.
Koj yuav tsum tsis txhob ua ib nplooj ntawv canonical uas tau raug tshem tawm los ntawm kev tshawb nrhiav txog qee yam (xws li cov tsis muaj npe los sis tsis nris ntawm cov ntaub ntawv robots.txt). Hauv kev txiav txim siab rau kev tshawb nrhiav cav kom pom ib nplooj ntawv uas yog canonical, nws yuav tsum muaj peev xwm siv nws thawj qhov chaw.
Cov chaw zoo los siv qhov kev sib raug zoo = canonical link muaj xws li:
- Cov chaw nrog dynamic URLs - Koj siv tau nws los txhais tau cov hom ntawv URL uas koj xav tau
- Eccmerce cov chaw, especiall ntawm cov khoom npe - Thaum twg koj cov neeg muas zaub hloov cov kev xaiv sorting, qhov URL tshiab tsis tas yuav tsum tau indexed
- Cov ntsiab lus sib txuas lus - cov neeg tshaj tawm uas siv cov ntsiab lus uas koj sau tau yuav tsum muaj qhov txuas = qhov txuas ntawm lawv cov nplooj ntawv taw rau koj daim ntawv qub
Thaum Tsis Siv Cov Canonical Txuas
Koj qhov kev xaiv thawj zaug yuav tsum yog 301 txhim kho. Qhov no tsis yog qhia rau lub cav tshawb nrhiav tias qhov URL URL tau hloov, tab sis nws kuj siv tib neeg mus tshaj plaws (thiab twv kuv hais, canonicol?) Version ntawm nplooj ntawv.
Tsis txhob tub nkeeg. Yog tias koj hloov koj tus qauv URL, ces siv qee tus HTTP header manipulation (xws li .htaccess lossis PHP los yog lwm tsab ntawv) ntxiv 301 redirects txiav.
Thaum koj siv tau qhov kev sib raug zoo = canonical txuas, uas tsis siv cov nplooj ntawv loj dua. Thiab yog li txhua tus neeg tuaj yeem tau mus rau lawv txhua lub sijhawm. Qhov tseeb, yog tias tus qhua muaj ib nplooj ntawv cim thiab koj hloov qhov URL, tiam sis tsuas yog hloov cov kev tshawb fawb xyaw nrog ib qho txuas = kev sib raug zoo, tus neeg yuav tsis pom cov nplooj ntawv tshiab.
Qhov rel = canonical txuas yog ib tug uas pab tau rau qhov chaw nrog ntau cov ntsiab lus sib npaug. Los ntawm kev nkag siab tias nws ua hauj lwm li cas, koj siv tau nws zoo. Tab sis thaum kawg, nws yog ib qho cuab yeej uas tau tso tawm los ntawm kev tshawb fawb xyaw kom pab lawv ceev lawv cov cim tshawb nrhiav. Yog hais tias koj tsis khaws koj cov neeg saib xyuas huv thiab ua kom tiav, koj cov neeg muas zaub yuav raug cuam tshuam thiab koj qhov chaw yuav raug mob. Siv nws lub luag haujlwm.
