My buddy AJ sent me a blog post that said five reasons why Google’s +1 button will succeed. Unfortunately, I have to disagree with him and I think it will be +1′ed out of Google faster than you can say “WTF is +1?”
The reason: SPAM.
When or if Google start using it as a ranking signal, people will figure out how to get lots of +1′s to benefit themselves and raise their own websites visibility in the SERPS. I can already get people as many Facebook Likes, Digg votes or any other votes as I wish including 1+’s as soon as they launch. I can even get them from a different IP every time and clicking through from a SERP as well as behaving like a user and not a bot. Now, imagine the abuse by a couple of hundred smart spammers.
If you want 200,000 +1′s, you can have them, tomorrow if so choose. With natural click intervals, IP ranges and even real verified Google accounts. Automatically and legally. I don’t even have to Crowd Source to get the votes, let alone even contemplate using real people.
There we have it, I think that Google’s +1 will be the single biggest opportunity of abuse ever to hit their Algo.
Here is my buddies blog post which advocates the +1 button.
C’est la vie
