But things are worse than that! With few exceptions (Stack Exchange and Wikipedia are notable) most searches will return sites that have been SEOd.
My Google search for [spectacles cases] returns these two sites on the first page:
(http://www.spectaclecases.co.uk/)
(http://www.aglassescase.co.uk/)
> Welcome to SpectacleCases.co.uk. You will find a wide selection of Glasses Cases / Spectacle Cases / Sunglass Cases.
> Made from leather, fabric, metal or plastic finished to a very high quality. Hard and soft cases for spectacles, glasses and sunglasses. We also have a good selection of cheap glasses cases which offer great protection for your glasses.
> Welcome to AGlassesCase.co.uk. The one stop shop for Glasses Cases, Spectacle Cases and Sunglass Cases. We also sell a number of Glasses Cloths
> Made from a range of quality materials including leather, fabric, metal and plastic all finished to a very high standard. We sell hard and soft cases for spectacles, glasses and sunglasses. We also have a good selection of cheap glasses cases which offer great protection for your glasses.
These two different sites are the same company.
Maybe they're a great place to buy spectacles cases from, but it's vaguely upsetting that Google can create freakin' awesome stuff (A self driving car! It is actually wonderful and futuristic) yet can't fix this stuff. Obviously, Google are not to blame, and really the problem is with sleazy SEO and odd behaviours by vendors.
