I'm thinking of purchasing links in various places on the Internet, such as blogs and websites in my niche, for the purpose of getting direct visitors to my website. However, I wouldn't mind if I also get a boost in the organic search results thanks to the additional incoming links to my site.
If I understand correctly, Google has some ways of spotting purchased links, although they can't be sure.
Now, I'm using a tracking script to help determine the results of my link purchases. That script works by adding a string such as ?ad=adgroup1 to the link, for instance: www.example.com/?ad=adgroup1 where example.com is my domain.
I could then assign an ad group ID such as adgroup1, adgroup2 etc. to all the different places I'm advertising on to track results.
What I'm asking is, would that help Google to detect that it's a purchased link? Let's face it, it doesn't look natural at all with an added string such as ?ad=adgroup1 to it.
What I fear is that it could make the link useless for SEO purposes, or even punish my website (unless it's nofollowed). I could still get the benefits of direct visitors through the links I buy, though, which is the main idea.
Any thoughts on this? Thanks.
