My most of the articles' pages has gone into supplement result which earlier were ranking on the first page of google. these articles were original and no duplicate content used or no kind of spamming was done. See if someone can come up with any particular reason: The URL is below (please omit in between spaces): www. coulsonpritchard.com/articles/income-protection-insurance. asp www. coulsonpritchard.com/articles/professional-indemnity-insurance-why-freelancers-need-it. asp www. coulsonpritchard.com/articles/contractor-banking. asp www. coulsonpritchard.com/articles/business-insurance-freelance-professionals. asp www. coulsonpritchard.com/articles/Income-Protection-For-Contractors. asp www. coulsonpritchard.com/articles/contractor-pensions. asp
If it's in supplemental result it means there is article that has been indexed first in other site or blog. Where did you post the article?
When You get some quality BL for Your pages You will back to main index of google One of the most importand factor to catch supp results is too poor BL for pages Reagrds
Yep, backlinks are usually the answer. But it looks like the site has quite a lot of decent links, and isn't very large, so I'm a bit surprised. One thing, did you change the menu system recently? Sometimes menus that aren't straight textlinks can cause problems. It is probably worth adding a sitemap of all the pages, with the sitemap linked from the homepage, to help things along.
my criteria for the supplemental pages is PAGE RANK as matt cutts wrote on his blog. i belive those pages has low page rank i think you have yo find more backlinks to these pages
