A new client wants me to redesign her existing art gallery site using a new domain. I am obviously aware (and have advised the client) that new domains can attract penalties in the serps (sandpit, new website filter etc). However, before I advise her to keep the existing site, do people believe that making significant changes in the keywords also produces a penalty/filter? I have read on a different forum a belief that drastically changing the keywords is the same as creating a new domain in Google's eyes. What are your views? Note that the current site is scarcely optimised at all - only the home page has a title tag, and this tag only says the name of the gallery and would therefore have to be changed to include terms liks "Scottish fine art" etc. I would be interested in any views.
