I have been a webmaster for the past 2 years, now recently google has introduced a new algo in their armoury, i.e supplemental results. A content is duplicated or insufficient links. Its one way contradictory to its previous algo. Because google said having thematical links will increase the chance of rankings. I have done that according to google words but i have a website it has more than 500 pages, due to this supplemental result concept 400 pages are gone into the shell i mean de promoted from the results. I assure all the contents are unique and written by our team. Only thing im still confused whether if someone copies the content of my website, then who should be penalized for the act, google software does nt seem to realize that , it has punished me hate this new supplemental results concept.
