hi there
there are links into the site from my BT and yell listing, and a lot of info is provided by those sources to search engine.
whilst i dislike with a passion paying for advertising the adwords works well at the moment, i agree with what you say to a point with regard to natural listing as opposed to sponsored listing.
i may well consider seo in the future, but i need to be careful in the number of customers i take at one go, controlled growth is important to us.
with regards to the commercial look of the site, the letterheads, leaflet inserts, site reports, business cards, and folders all follow on from the web theme, along with colour of vehicle livery and office signage.
the branding whilst not as flamboyant as some, delivers a clean image to our potential and existing clients, the services that we then provide deliver the same message.
regards
martin
