Det var lige præcis det eksperiment jeg tænkte på, tak :) |
Jeg vil sige at rel="nofollow" er en google ting
før yahoo bliv til bing tog yahoo alle links også links med rel="nofollow"
men kort sagt alle links har en værdi, bare ikke overfor google
google tager ikke rel="nofollow" links med i sin index
http://en.wikipedia.org/wiki/Nofollow
Google announced in early 2005 that hyperlinks with rel="nofollow"
[4] would not influence the link target's PageRank.[5] In addition, the Yahoo and Bing search engines also respect this attribute value.
On June 15, 2009, Matt Cutts, a well-known software engineer of Google, announced on his blog that GoogleBot will no longer treat nofollowed links in the same way, in order to prevent webmasters from using nofollow for PageRank sculpting. As a result of this change the usage of nofollow leads to evaporation of pagerank.[citation needed] In order to avoid the above, SEOs developed alternative techniques that replace nofollowed tags with obfuscated JavaScript code and thus permit PageRank sculpting. Additionally several solutions have been suggested that include the usage of iframes, Flash and JavaScript.[citation needed]
