did you watch that video with Mat Cutts explaining what is a paid link? he explains there how they detect whether a link is paid or not.
Oh yes, Matt Cutts, prostitute paid by Google, mouthpiece who's job is to deceive public
by telling public that "back links" our friends, use Links Wheels charts in my YouTube video
to learn how to get as many links as possibly you can... oh, wait, that was 5, 6 years ago
before Google decided that "back links" are bad, bad, bad and we will fight the same
public who have followed our advice and got a tons of them.
No self-respected Webmaster or Real SEO will listen any-longer to what that dickhead is
"preaching" to weak-minded "peasanos" who are trying to sell his gospel to jackasses.
Another thing is that Google doesn't penalize a site just for paid links.
ooopps, I forgot Google now penalizes sites for just having link... good or bad
Google penalizes a site if it breaches several google's policies,
Can you make clear for us, which policies are you talking about, the one it has
5 years ago and now changed them because it finally realized they where stupid?
Or the one, I can bet, it will changing within a next update... sometimes next week?
But if Google mentions that your site is overwhelmed with paid links (and what's more those link are of low quality), it'll ÐµÑ„Ð»Ñƒ some measures to your site
Get it to your head.
Google doesn't know which link is which or it would ban thousands of sites already without
asking public to go to every site they have had link years back and ask owners to remove
these links G. wants you to have in a first place.
