I've come across a method implemented by some SEO agencies to fill up pages with somehow relevant text and hide it behind a javascript dropdown. Does Google fall for such cheap tricks? You can see this method used on these pages for example (just scroll down to the bottom) - it's all in German, but you get the idea I guess: http://www.insider-boersenbrief.de/ http://www.deko-und-kerzenshop.de/ How is you experience with this way of adding content to a site? Do you think it is valuable or will it get penalised?

My clients business is divided in chain stores. All stores are set under the same franchise. There is one domain www.company.com with branches like www.company.com/location1/content and www.company.com/location2/content etc. I've taken care of duplicate content issues with rel="canonical" and duplicate page titles are also not a concern, anymore. Right now the concept is like this: If you visit the site for the first time you get to choose between the locations. Then a cookie is set and once you revisit www.company.com it will redirect you via a php header command to the location stored in your cookie: www.company.com/location1/content. My question is if this might hurt rankings in some kind of way as these aren't permanent redirects with a 301 but rather individual ones, based on your cookie.
