Thanks for your replies and advices.
The website hasn`t been released yet, and we are still having some changes done thats why it still runs under eazysecure.
The website aims mainly professionals(builders, architects, contractors...)so they know the definition of each word.The site is not for buying online but they send us their enquiries and we send them samples.
I will speak to the webdesigner regarding your comments for SEO, at least i know a bit more now
For the pay per click, i requested info from Google Adwords, and they told me that to be at the top of the ranking, we need to increase quality scores and the Cost per click, so does that mean that we need a good quality of website and to have the higher bid to get at the top?
Also the more keyword we have the better we have the chance to go up ?
Sorry for asking all these questions

but i am not an expert in that field, so i really appreciate your help.
