IMHO you and people like you are lower than a snakes belly.
heck yes i'd take the job (obviously!), especially when it is a malicious site...no reason to stand there and let someone sucker-punch you all day...hit them back.
Have you considered that maybe the person has a legitimate beef that the provider has failed to address?
And what would "real seo" be in this case ?
rank 9 (NINE) additional sites just to outrank 1 ?
My god.. i have better things to do, seriously.
That site is no competitor, but a 100% hate site - why even ask ? i'd do it without thinking about it for a second.
You are taking the wrong view of this whole situation.
Haha. Elitist
So his client pays his bills. asks for him to do service X. yet you are telling him to offer his client service Y ?
Im making 1-5k € a month. depending on the season. and i do whatever my customers are asking me to do.
because u know... they are paying my bills, amirite?
And sorry but no. you are NOT his client. because his client asked him to nuke that site that tries to HARM HIM. not to "fix" anything. read again, mister exclusive status donor vip sir.
You are also looking at things the wrong way. I will explain further down the line.
I would personally buy fiverr gigs (xrummer and scrapebox) and blast it off the map. Why spend how many hours trying to fill up the first page with a bunch of stuff when you can literally get rid of them in minutes. Quick, cheap, easy, and effective. NOW the only problem is that you have to worry about him doing this to your site, which shouldnt be much of a concern because chances are if he knows about it he will do it anyways since he is obviously pissed off. If I was him I would blast your site as well, which will probably happen anyways.
Retaliation can be worse than the original problem.
What IF you had an OFFLINE business making $100,000 in revenue monthly - and a client from hell creates a hate website about your business and your revenue drops to $20,000 .
After trying every issue to resolve the situation with said client, he still refuses to take down the hate site, and negotiates with ridiculous demands and possible extortion.
Would you do Negative SEO to take down his site ?
Never. As a business person you need to address the issues not create more of them. Letting a negative campaign get under your skin will tear you apart. If you are making 100k and have no reserves to weather the storm then you are at fault. You need to learn to live on less than you make. This guy will not last if he has to resort to these tactics.
To the ones that have answered YES to this question, you are not looking at the whole picture.
You can make more money doing things the right way. Negative SEO (if it works as there are no guarantees) will give you a shot of cash but it will be very short lived. You knock the site down and you are done. How much is that going to bring you $200, $500 or $1000?
Now if you sell the customer on the correct way to combat this, you can rake in the money. Charge for building the other sites and a monthly fee for ongoing reputation management. Depending on the size of the company and the difficulty of ranking, you can bring in hundreds or thousands of dollars every month for months on end.
It is not your fault that the customer is in this predicament but you also have to keep your reputation in mind. You also need to figure out a way to turn this negative into a long term positive for you as well as your customer. Repeat business is where the money is made not in the one time sales.
Pull your heads out of your asses and wake up to the real world. If you were operating real businesses this would not even be an issue for you to decide. Having a business license only makes you a legal business, how you operate makes you a real business.
The customer caused his own issues and will need to pay someone to have this rectified. In the long run, the use of other sites to knock the negative site off the first page will have longer lasting effects and have longer lasting income for you.
Most of you in this thread need to just leave the offline customers alone as all you are going to do is hurt them in the long run because you do not know what you are doing.
