What do you mean keywords? Like searching for something or adding keywords to a site to help it be found on google? If looking for keywords for your site I would use the common ones like detailing, car wash, polishers, ext.
Oh wait, you mean when looking for detailing stuff? It's tough for me to answer that question, as I normally just come here, and rely on the other member's experiences and suggestions. I suppose add all the brand names you carry. Swissvax, collinite, lusso, P21S, etc. Also things like paint sealant, car wax, carnauba, etc.
Phil- Put what you want to key on in quotes. For example detailing products "Menzerna polishes". Or Menzerna "retailers" HTH
:worship2: Amen for bookmarks!!! For all the sites I stumble upon or get linked to, I would never remember them all. My cousin calls me the "Bookmark King" because I have rows an folders of links, but guess who can't remember a site when he needs it...!? As for keywords, all things relevant to your specific site, items and field. Name brands, waxes, microfibers, buffers etc. What would also be good to do is just google words you would want or consider and see what the search result comes back with. That can give you an idea of what words are more searched for then others.
As far as I'm aware keywords are not going to do to much with respect to Page Rank on Google. Googles spider isn't your run of the mill keyword indexing system (very few search engines are these days). It is a good idea to have products and terms in your META tags so that they at least get flagged for that term, but they aren't going to do much to your Page Rank. I would concentrate more on linkbacks from partners. Here is an article on Google's Page Ranking system: Rules to Better Google Rankings -Shane
