„NoFollow“ – kokia tokios nuorodos vertė?

Kas yra „NoFollow“?

 

„NoFollow“ tai „rel“ atributo reikšmė, kuri gali būti priskirta HTML „a“ elementui.

Ši reikšmė HTML kode gali atrodyti taip:

 

<a href="http://www.pavyzdys.com/" rel="nofollow">
Nuorodos tekstas</a>.

 

NoFollow tai pranešimas paieškos varikliams, kad jie nesektu šia nuoroda. Tokiu būdu svetainės, kurioje yra nuoroda šeimininkas praneša paieškos varikliams, kad šia nuoroda nepasitiki.

 

Tai ypač aktualu, kai svetainėje yra vartotojų generuojamo turinio, komentarų ir panašiai.

 

„NoFollow“ pirmą kartą pasiūlė Google kompanija 2005m. tam, kad  paieškos varikliai galėtų efektyviau kovoti su komentarų SPAM’u. Šiuo metu dauguma didžiųjų portalų, dienraščių, tinklaraščių naudoja „NoFollow“ reikšmę.

 

 

Ar „NoFollow“ nuorodos gali padėti pakelti svetainę Google paieškoje?

 

 

Trumpai kalbant – ne.

 

Drąsiai galima sakyti, bent jau tiek, kad svetainė vien dėl  „NoFollow“ nuorodų Google paieškoje tikrai aukštai neiškils, nors jų bus ir „kvadrantilijonas“. Jeigu kas nors bandėte tokią strategiją ir tai Jums suteikė pastebimą teigiamą poslinkį – rašykite komentarus, būtų įdomu išklausyti.

 

 

Oficialūs faktai iš Google:

 

  • „NoFollow“ nuorodos neperduoda PageRank vertės.
  • „NoFollow“ nuorodos neperduoda  pasitikėjimo mato.

 

http://www.google.com/support/webmasters/bin/answer.py?answer=96569

 

Visgi paoponuoti galima tuo, kad:

 

 

PageRank yra tik vienas iš 200 Google algoritmo veiksnių, taigi jis yra ne tiek svarbus, kaip daugelis žmonių mano.

 

O dėl pasitikėjimo, tai ir TAIP ir NE. 

 

Taip – labai tikėtina, kad Google neperduoda pasitikėjimo tiesiogiai per „NoFollow“ nuorodas.

 

Ne – taip pat tikėtina (nors trūksta įrodymų), kad Google vertina visą konkrečios svetainės nuorodų „portfeli“ ir kokį procentą, tos svetainės nuorodų sudaro „NoFollow“ ir „DoFollow“ nuorodos. Jeigu sakykime, kad Jūsų svetainė staiga įgijo keletą ar keliolika tūkstančių nuorodų ir VISOS jos yra „DoFollow“ – tai Google algoritmui gali sukelti įtarimą, kad tos nuorodos buvo nupirktos ar kitais manipuliuojančiais metodais surinktos.

 

Taigi, turėti  „NoFollow“ nuorodų  „dėl kvapo“ (3-10%) manau yra labai teisinga praktika.

 

 

Dar keli įdomesni faktai/gandai/pastebėjimai apie „NoFollow“:

 

1. Paprastų svetainės lankytojų neįtakoja „NoFollow“, taigi per šią nuorodą vis tiek ateis (gali ateiti) lankytojų, kurie tiesiog paspaudžia ant nuorodos.

 

2. Nors Google neįtraukia šios nuorodos kaip „balso“ savo algoritme, visgi jie ja nuseka... Ir „NoFollow“ tikrai padeda greičiau atrasti (suindeksuoti)  svetainę paieškos varikliams.

JohnMu, Google Employee,  čia taip sako:

 

„This does not mean that the target URL will never be crawled. By adding a rel=nofollow to a link, you're essentially removing a sign pointing to the restroom. Just because that sign is gone does not mean that Googlebot will never find the restroom. Using rel=nofollow is not a way to block crawling altogether -- if you need to do that, then use the robots.txt file.“

 

3. Jeigu žiūrėsite per „Webmaster tools“ aplinką savo nuorodų portfelį, pamatysime jame ir „NoFollow“ nuorodas. Jeigu jos būtų bevertės, kam Google jas skaičiuotų ir pateiktų svetainių savininkams?

 

4. Toliau – čia tik mano pastebėjimas. Esu stebėjęs ne vieno tikrai patyrusio „SEOisto“ nuorodų statybos rezultatus. Ir juose dažniausiai yra nemažai „NoFollow“ nuorodų. Nemanau, kad jie nežino ką daro, ar neturi kur savo laiko efektyviau panaudoti.

Totalus melas, gal kažkada taip ir buvo, bet dabar pats žiutiu iki PR2 vien su nofollow uzkeliau.
Mindaugas
Nepamirskite, kad PageRank teka (pasiskirsto) svetaines viduje. Kita vertus, jeigu Jusu visa svetaine neturi nei vienos DoFollow nuorodos, manau, kad greitai virs PageRank=0 pakilti nepavyks.
Justas
Nofollow nereikia taip nuvertinti kaip čia kad bandoma rašyt. Visų pirma, šie nuorodų atributai tikrai "ne dėl kvapo", o padeda spręsti įvarias dublikatų problemas, mokamas nuorodas ir pan. Už šituos dalykus bent google baudžia, taip kad nofollow taip jau bendrai kalbant tikrai padeda "pakelti" reitingus.

Doctor Who is now considered a British Institute and has come a long way since it first aired on November 23rd 1963. The very first show saw the Doctor travel 100,00 years into the past to help some dim cavemen discover light. After 26 seasons and seven Doctors later the series came off our screens in 1989 much to the disappointment of the huge devoted fanbase. In 1996 an attempt was made to revive Doctor Who but it wasnt until June 2005 when it came back with a vengeance with Christopher Eccleston as the ninth Doctor that put the series back on the map as it were. It then went on for 5 years with David Tenant portraying the Doctor until 2010 when Matt Smith took over the role. Today it is still a great family show and has attracted many new fans. If youre a new or old fan of the show there are Tours and museums you can go and see some of the locations and memorabilia of this classic show. The Doctor Who Tour of London will take you on over 15 locations from the show, some from the new series and some from old sites like the location of The Invasion and Resurrection of the Darleks. The tour also takes you to the TV museum in London where you will get to see some of the cosumes worn in the show and props used. Also you can buy gifts and memorabilia from the shop. You will learn all about how the shows were made so the tour is also educational. If you want to take pictures of the locations thats not a problem. Remember the front door of 10 Downing Street in Aliens of London? Well you can get up and close to this and get your picture taken in front of the door. Rose Tyler fans will love the tour as you get to drop by her home in the show. Why not go that extra mile and actually meet a Doctor Who star. Well this is possible with private or group tours. You will get the general tour but included will be a pre-arranged meeting or lunch with a celebrity from the show. This will obviously depend on availability of the celebrity and the cost will reflect the popularity of that celebrity. There are tours in London and also Wales. The Wales tours take you to Cardiff where you will see lots of location which were featured in shows since 2005. You can leave from London or at Leigh Delamere services station on the M4. There is a Doctor Who exhibition in Cardiff which you get to see. At the end of the Doctor Who tour you get a souvenir group picture sent you by email which is a nice touch. For seriously devoted Doctor Who fans there is a 3 day tour which takes you to all the locations in both London and Cardiff. You will see locations from the past 45 years as well as recent sites from the lasted Doctor Who series. Day one is based in London where you get to see 15 sites. Day two takes you to Cardiff where you get to mean the real life owner of the to see we have an Gothic property used as the location of the school in Human Nature. The final day is partly spent in Cardiff with a walking tour at Cardiff Bay, then you head back to London but a stop at Stonehenge to see the site of the Pandoica. Then its dinner at The Cloven Hoof pub in Devils End b efore you taken back to central London.

A Biological Masterpiece, But Subject to Many Ills The human foot is a biological masterpiece. Its strong, flexible, and functional design enables it to do its job well and without complaint—if you take care of it and don't take it for granted. healthThe foot can be compared to a finely tuned race car, or a space shuttle, vehicles whose function dictates their design and structure. And like them, the human foot is complex, containing within its relatively small size 26 bones (the two feet contain a quarter of all the bones in the body), 33 joints, and a network of more than 100 tendons, muscles, and ligaments, to say nothing of blood vessels and nerves. <a >https://www.cialissansordonnancefr24.com/cialis-prix-conseille-en-pharmacie/</a>
