Hi to everyone, I would like to say my story. (It's small, don't worry! ) So, i have a company website. At the past at [keyword1] i have a 30-40 position, and at [keyword1 keyword2] (phrase) i had 14-24 position for the same url (mysite.gr/url1). At the start of the new year i decide to "promote" my site. I wrote 5 articles andi submit them at article directories, and i bought about 10 blog comments (manually supposed!) from fiverr. My articles have anchor txt [keyword1] with link to my url. After these actions, i ranked at 10th position for [keyword1] and at 9th for [keyword1 keyword2]. But, at 15-16 Jan my site dropped very much. [keyword1] dissapeared at all. [keyword1 keyword2] rank 38th position. (same url) The keywords are very low competion keywords. I know that at this period there is a g update, but is there any case that i get penalty for one keyword? The website is company, so i cannot add many content yet. Also, at past before 1-2 years i had use an x-rumer service but no affect then. My todays backlnks are 258, ~90 doffolow from my blog (i have put the website url with anchror text [keyword1] at my blogrolls, ~90 nofollow from a forum that i participate, and the rest backlinks are from some directories and about 20-25 from the x-rumer above service that they remain today. At webmastertools i have not recieve any message. All the above are for the same url of my domain. What do you suggest me? Have i get penalty for one keyword? Sorry for my pure English.
