You or someone, company, or website owner you may know must have suffered from Google penalty issues. Actually, it’s a common problem and quite a number of people are acquainted with it. The good thing about Google penalty is that it can be rectified by professionals in the business.
The common cause of penalty is Panda or what they called quality algorithm. Apart from Panda being the cause of ban, others are malware, Penguin and manual. The intensity of the problem includes de-indexing action, zero ranking, and lesser ranking. Google uses algorithm that gauges quality to inspect your site and if the result of the inspection comes back as low-quality, the search engine will allocate a low score to your website hence making it difficult to receive any position in any search engine.
