We have been hit extremely hard by the latest google panda and penguin updates. We previously used a seo firm that got us good results that told us they only use white hat techniques; this was obviously not the case, and we are paying for it now. We have received a message in google webmasters that states that there are: artificial or unnatural links pointing to your site that could be intended to manipulate PageRank. We can provide a copy of links from our webmasters page, and a link report from opensiteexplorer. You will also need to pull a link report from ahrefs and majestic seo. We will need for you to identify all unnatural links (domains) and have them taken down. We want a freelancer who has successful experiences in link removal and reconsideration requests for google. Freelancer must be very thorough in reviewing ALL links. Please send references or past projects of the same nature. We would only like to use google's disavow tool as a last resort.
