Many website owners fall into the trap of buying links from other people.
This is dangerous for many reasons, but the most important reason of all is that it’s against Google’s rules.
If you are caught doing anything to manipulate their results unjustly, your site will be penalized.
How will Google find out if you buy links?
Honestly, it’s entirely possible that Google will never find out.
That’s a risk you take.
Google is always on the lookout for anything that looks suspicious.
Every hour of the day, Google is crawling the web and indexing everything.
It’s difficult to keep anything from a company that has so many resources.
