The Plus One service I utilize is listed here on my SEO software, Tools and Services page. While waiting for your +1s to be delivered here’s a tried and test guide on how to buy Plus Ones. The best way to find out the impact of a Plus One campaign is to take a look in the Google Webmaster Tools section called +1 Metrics. There you will find a glimpse of how Google collects +1 data and uses it to aid their search results.
There you will also find Search Impact, Activity and Audience and definitely check out the +1 Metrics FAQs too. Without getting too far into the explanation I can easily sum it up by saying Google’s Plus one algorithms include measuring the value of the +1 by the user’s activity. In other words, if someone with a weak Google Plus profile pluses a page and then never comes back, its a very weak + but if the Google account they are Plusing from has many friend, followers and activity and on top of that they continue to revisit the site, then it will boost your SERPs faster than links.
The best search engine algorithms are always the simplest. The +1 system isn’t 100% spam proof but they have found a simple way to combat it by using data that is hard to replicate or automate. In the beginning Google floundered in the social search arena but this time they found a way to 1up (no pun intended) Bing’s social search.
Buy +1s From a Trusted Network
This being said, it looks like the best way to buy +1s is to make sure the network of Google accounts are PVA and not only look authentic but also have natural behavior in their Google Plus profile as well as other Google services. Here’s a few tips of what a good +1 looks like. Many friends followers and recent posts on Plus and some have even suggested to setup blogger, Youtube, search history even email activity can build power and legitimacy to a Google account. As my colleague Dean put it, “I want to get a lot of good followers on Plus that way it will increase my Plus power. I’d be a PR5 in the Plus world”.
Sure buying +1s can be great for SEO but only if they are coming from good Google accounts. If you are buying them from an exchange network this will be easier to assure but if you are buying them from a company or some dude on a forum somewhere then make sure their network of Google accounts is worth a damn.
