Googles spamteam har lagt ut information om hur länakr påverkar en hemsidas ranking på deras blogg, Inside Google Sitemaps.

We find links to your site through our regular crawling mechanisms, so there's no need to tell us separately. Keep in mind that our algorithms can distinguish natural links from unnatural links.
Google kan alltså avgöra hur länken skapats och om det är en bra (natural) eller dålig länk (unnatural).
Unnatural links are links to your site placed there specifically to make your site look more popular to search engines. Some of these types of links are covered in our webmaster guidelines:
Don't participate in link schemes designed to increase your site's ranking or PageRank. In particular, avoid links to web spammers or "bad neighborhoods" on the web, as your own ranking may be affected adversely by those links.
Avoid "doorway" pages created just for search engines.
In general, linking to web spammers and "bad neighborhoods" can harm your site's indexing and ranking. And while links from these sites won't harm your site, they won't help your indexing or ranking. Only natural links add value and are helpful for indexing and ranking your site.
Det hjälper inte din ranking att delta i olika länknätverk om de inte tillför din hemsida någto eller om inte din hemsida tillför den du länkar till. Det är dock helt tillåtet att länka till vem man vill (utom till "bad neighborhoods") men det påverkar inte din ranking hos Google. Det kan däremot skapa en ökad trafik till hemsidan att ha länkar på andras hemsidor.
My site participates in an affiliate program. What tips can you provide?
Google's goal is to provide relevant and useful results to searchers. Make sure that your site provides unique content that adds value beyond an affiliate link or the content provided as part of the program. We talk about this in our webmaster guidelines as well:
Avoid "cookie cutter" approaches such as affiliate programs with little or no original content.
If your site participates in an affiliate program, make sure that your site adds value. Provide unique and relevant content that gives users a reason to visit your site first.
Look at your site and determine what you can offer that will make searchers want to visit and what can distinguish it from other sites in the same affiliate program. And while we expanded on the information in our guidelines specifically because so many people asked us about their affiliate sites, this information is true for all sites. If there's no added value to users, then it's unlikely that search engines will find added value either.
Innehåll, innehåll och åter innehåll! Se till att ha ett bra innehåll på hemsidan så kommer en bättre ranking naturligt.
