I work as a SEO employee ( for a PR5 site) where we are doing all white hat stuffs like doc submission, slide submission, article submission, blog post, social media etc for our client. But the problem is for last one month we are not seeing any improvement in SERP and even our keywords started loosing rank.(almost 20 keywords lost first page ranking) I checked Google webmaster account but there was no critical message.
After analyzing the whole thing we assume that Google seems to devalue our work because most of the SEO work from our employees are coming from same IP address.(Please correct me if I am wrong)
We are really concerned about getting our keywords back in first page. Therefore, any suggestion from fellow warriors to improve our condition would be of great help!
Looking forward to the reply
