Is this guaranteed to work? Is it risky?

If anyone offers you a search engine optimization guarantee run away as fast as possible. There are no guarantees in SEO, unless you happen to own Google (in which case: Hi Sergey / Larry! Thanks for stopping by!).

There are innumerable factors that can affect search engine rankings. And, realistically, most sites should focus their efforts on traditional SEO before using non-traditional techniques like SerpClix.

Ok, no guarantees. But it does work, right?

While backlinks and content remain the dominant factor in SEO, over the past few years Google seems to have been moving more towards user feedback signals like engagement, retention and bounce rates. We believe Google will continue to move away from external signals like backlinks and move towards user experience signals. This seems to have already been done with YouTube. YouTube videos used to be ranked based on thumbs up, view count and comments, but now it's all about user experience and engagement. If someone leaves the video instantly, it ranks lower. If they watch the full video, it ranks higher. We believe the same things are being applied in the SERPs (search engine results pages).

Is it risky?

All SEO efforts can involve an element of risk. Some techniques are certainly more risky than others. SerpClix employs real human clickers, so we think our service is far less risky than trying to use automated or robotic click methods which are not only risky but simply do not work. But, like all SEO strategies, there is an element of risk because Google’s algorithm is unknown and subject to change at any time.

That said, it is highly unlikely that a site would be penalized for trying to boost their CTR. If this was so, then people would be using this method against their competitors! 

Google always has to be careful of unintended consequences. This happened before when they were penalizing sites who were linked to from "bad neighborhoods" and black hat SEOs quickly realized they could employ this technique against their competitors' sites and get them penalized! So, for this reason if nothing else, it's extremely unlikely that our service would ever result in any kind of penalty.
