I have a wedding car hire website.

www.finestweddingcars.co.uk

I am trying to improve the SEO and just want to clarify how i should put my keywords.

If people search "wedding cars Sussex" is that a key word / phrase and if so i just put this seperated by a comma or is that 3 keywords Wedding, cars, sussex,

Then the same with "Chauffeur driven wedding cars" so again a keyword/phrase or just adding Chauffeur, Driven, will then cover both phrases

I hope that makes sense so I either have 2 phrases or 5 keywords

Also is there a recommended number of keywords / phrases

Thanks in advance for your help
