Now, what are the odds of your competitor doing this to your websites? Back then, I used to have two websites ranking on the first page of Google.
A week later, those two sites were then ranked on page 20! What the heck happened? Well, as I was checking my backlinks, the sites were spammed and it appears someone to build tons of backlinks to my site quick.
So, rather than having your whitehat competitors trying to outrank you by building their own backlinks the ethical way on their own website...blackhat competitors will try to knock your site off Google by spamming your site?
How would you protect your websites from such incident?
