Just few hours ago i browsed a lot of +1 exchange and +1 sell websites and thought that is a great opportunity since is new enough to dominate the market.
I planed to offer +1 packages on cheap rates for any website owner and the simply outsource the job to other websites and just take the revenue. Sounds good, easy plan that has to work. Wanted to start instantly bout I thought that i sleep one more on it.
Now i wake up and check this out: Google removed every +1's that i got from these sites and services. Spent few bucks on it to test the services for outsourcing. Seems that all +1's that are not coming from the search results or from the page itself, ARE REMOVED BY GOOGLE.
Ok i think that this is OK, since we probably will have a more cleaner system like the other ones. I'm pissed of a bit for the spent dollars but also I'm happy that i don't begun the process and don't buyd domain for the service also promotion was not started so i WON only with a few hours.
My advice, don't buy any +1's even if you want to. Wait until the site owners find some solution for it or buy only real +1's from peoples that visit your website, and +1 it.
