En ny och intressant post angående länkar som ger en liten inblick i Googles tänkande. Intressant, intressant.

Här till exempel bekräftas att Google nu kan känna igen till exempel köpta länkar.

At this point, someone usually asks me: “But can’t you just not count the bad links? On the dailycal.org, I see the words ‘Sponsored Resources’. Can’t search engines detect paid links?” Yes, Google has a variety of algorithmic methods of detecting such links, and they work pretty well.

However, link-selling sites can lose their ability to give reputation (e.g. PageRank and anchortext).

Detta betyder att det finns en osynlig faktor i deras algo som filtrerar bort dessa länkars värde i deras beräkningar.

Angående "rel=nofollow":

What if a site wants to buy links purely for visitor click traffic, to build buzz, or to support another site? In that situation, I would use the rel=”nofollow” attribute. The nofollow tag allows a site to add a link that abstains from being an editorial vote. Using nofollow is a safe way to buy links, because it’s a machine-readable way to specify that a link doesn’t have to be counted as a vote by a search engine.

Skrivet alltså av en Google staff.

Saxat från hans kommentarer:

one thing that Google and probably most search engines have developed is the ability to look at site-level linkage. So buying a ton of links from a lot of smaller sites can stand out even more than buying a link from a well-known site.
