I analyzed one of my competitors backlinks & saw that he added his backlink in near 20 domains (own by one person) & then for some reason they delete the backlink (because now I check the backinks but there was no links available anymore). This caused them to be number one for the term pest Control, in Australia, even though their website is not quite perfect.
So my question here is this: Is this safe?
This is one of the 20 websites I mentioned : 88ba.org
Totally garbage website just for making links for their clients & Deleting them to avoid Panda penalty .
Can I Do the same? is it safe?
