Yes...Those links are considered as irrelevant links...
Google doesn't take it in to account.
But not sure,google may punish you for it...
Under your example, I could go to an adult site, post a bunch of links to my competition and get them a penalty?
Sorry, but that is not how it works.
Relevance plays a factor, but so do dozens of other factors. Some people say that google uses something close to 200 factors to rank a site. And "relevance" is just one of them.
To make the math easy, lets say that google uses 100 factors to rank a site. So "relevance of backlinks" is 1% of the total.
If google uses 200 factors, "relevance of backlinks" is 1/2 of 1%.
I can live with those numbers.
@texashiker and Sandeep..
Did i miss something?? Can you explain the question to me??
He wants to know if he puts a link on his old site, going to his new site, if it will be ok.
sandeepdude said those are irrelevant links and google might give you a penality.
I said irrelevant links are still a link, and you will NOT get a penalty. Google uses so many factors to rank a site, that having some irrelevant links is not going to hurt you.
rome9t9 - does that explain it a little better?
coming to proxysites.ca's question..I dont think it will hurt you..we can see Sandeep linking to his Ghillie Suites and Health blog from Netbuilders in his sig..they both are of different niches than NB..but it wont hurt you...
The links wont be "worthless" ..but they will be "worth less"
No mention of having links from relevant sites.Make sure that other sites link to yours
Links help our crawlers find your site and can give your site greater visibility in our search results.
As far as I know, the only time the Google Webmaster Guidelines references relevant links, is when the topic turns to buying and selling of links that pass page rank.
The "Quality" of the linking site is referenced several times - more so then "relevance." That means that the quality of the linking site is more important then its relevance.Your site's ranking in Google search results is partly based on analysis of those sites that link to you. The quantity, quality, and relevance of links count towards your rating. The sites that link to you can provide context about the subject matter of your site, and can indicate its quality and popularity. However, some webmasters engage in link exchange schemes and build partner pages exclusively for the sake of cross-linking, disregarding the quality of the links, the sources, and the long-term impact it will have on their sites.
1 reference to relevance.
3 references to quality.
Quality means whether the site is full of spam, full of duplicate content, promoting copyright infringement,,, stuff like that.
Now then, do you have anything from google webmaster guidelines that says having links from irrelevant sites will get you a penalty?
